Summary
Yes, in 2026 it got worse: on 28 May ESSMAR activated its drought plan when inflow to the Mamatoco plant fell from about 750 to 560 liters per second (−25%), and on 15 July a damaged 28-inch main cut water to 19,372 users in 58 neighborhoods.
The problem is old. A 2017 study measured 46.8% non-revenue water, and when Superservicios took over ESSMAR in November 2021, average continuity was only 70.8%, about 17 hours a day.
It's not that the city has no water. El Roble's inflow also fell, from 500 to 450 liters per second, and with no big reservoir, drought, muddy rivers after heavy rain and a leaky network keep breaking the chain between river and tap.
Losses are the quiet problem: ANI's infrastructure plan (October 2025) still uses a 58% loss baseline and aims for 27%.
Average hours did improve, from about 17 to a 20.5-hour planning baseline, but tankers are still routine: on 4 June 2026 ESSMAR said it had supplied 90 neighborhoods by alternative means over three months.
Growth makes it harder. The city has more than 650,000 people, the airport handled 3.79 million passengers in 2025, and the Irotama pump upgrade added just 38 liters per second, about 6% of what the planned 600 l/s desalination plant would bring.
One failure now hits tens of thousands: in July 2025 an illegal blockage at the Manzanares intake cut about 350 liters per second, 45% of Mamatoco's usual inflow.
Tap water isn't the issue: on 1 July 2026 ESSMAR said its IRCA risk index had stayed below 5% across 70 sampling points.
Repairs are too small, and desalination stalled: the Ministry of Housing launched the selection on 19 June 2026, but on 19 August ESSMAR said no tender, award or contract was running.
Superservicios handed ESSMAR back to the city in August 2026 after almost five years of intervention, and kept it under special supervision for six months.
Cutting losses from 58% to 27% would recover 31 points of the water the city already produces, part of it real leaks, part of it unbilled water.
Climate is the wild card: on 13 August 2026 IDEAM gave El Niño a more than 90% chance of lasting into early 2027, and the city is closer to a fix on paper (a COP 6.14 trillion plan) than in the pipes.
Since 16 September 2026 ESSMAR has shut the Manzanares supply line every week from Tuesday 4 p.m. to Friday 6 a.m., and in October residents were collecting 50,000 signatures to protect about COP 786 billion (about $246 million) set aside for water.
For a buyer, the useful answer: value any property as if today's supply lasts for years, and at US$3,000+ per m² in Bello Horizonte or Pozos Colorados, ask for the cistern size, days of autonomy and the building's 2026 tanker bills before you negotiate.
What actually changed for Santa Marta's water in 2026?
It got worse, even though a few parts of the system are healthier than they were in 2021.
The clearest deterioration was on the supply side. On 28 May 2026 ESSMAR activated its dry-season plan, saying El Niño and a harsh summer were cutting the water reaching its treatment plants. Inflow at Mamatoco fell from about 750 to 560 liters per second; El Roble fell from roughly 500 to 450.
Then came the failures. On 15 July 2026 third-party excavation damaged a 28-inch main, cutting water to 19,372 users in 58 neighborhoods. A community closure of the Piedras intake reduced flow into Mamatoco while rivers were already low. On 30 August a transformer failure at the Rebombeo pumping station hit 14 southern sectors, and since 16 September ESSMAR has shut the Manzanares supply line every week to get more river water into the plant.
The climate outlook didn't help. On 13 August 2026 IDEAM said El Niño was strengthening, with more than a 90% probability of lasting at least into the first quarter of 2027 and a 69% probability of reaching the “very strong” category in October–December 2026.
There is one important counterargument. Santa Marta appears to have improved average water continuity since the conditions that triggered the national intervention of ESSMAR in 2021, and official drinking-water quality has improved considerably. We therefore would not describe the whole water system as deteriorating.
What got worse in 2026 is Santa Marta’s margin for error. The city still lacks enough dependable supply, still loses an enormous amount of water and still needs tankers when the rivers fall. A strong El Niño is testing that same weak system before its biggest planned fix even has a contract.
| What we checked | Situation now | Direction | Our reading |
|---|---|---|---|
| River supply | Flows into major treatment plants have fallen | Worse | Immediate pressure |
| Climate | El Niño strengthening (IDEAM, August 2026) | Worse | Higher drought risk |
| Average continuity | Better than around the 2021 intervention | Better | Real progress |
| Water losses | Planning baseline remains around 58% | Poor | Structural problem |
| Water quality | IRCA remains below 5% | Better | Clear improvement |
| New large supply | Desalination plant has no contract (ESSMAR, 19 Aug 2026) | Unchanged for residents | Relief has not arrived |
Has Santa Marta always had this kind of water shortage?
Yes. Santa Marta has had a serious water shortage for years, which is exactly why the current deterioration cannot be blamed on one bad summer.
Engineering research was already identifying a large mismatch between Santa Marta’s water demand and its ability to supply that demand almost a decade ago. A 2017 study reported non-revenue water of 46.8% and described water scarcity as a central problem for the city.
Conditions later became worse. When Superservicios intervened ESSMAR in November 2021, average water continuity was only 70.8%, roughly 17 hours a day, and the regulator described water losses as very high.
ESSMAR itself calls the shortage a structural supply deficit that has lasted decades. Estimates of that gap, from roughly a quarter of demand in wet months to around half in dry ones, circulated around 2023, but we found no recent official figure to confirm them, so we don't treat them as a current reading. They still point in the same direction: Santa Marta has repeatedly lacked enough reliable water for full demand.
Today’s problems therefore sit on top of an old deficit. What has changed is the amount of pressure being placed on that deficit.
| Period | What was happening | What it tells us |
|---|---|---|
| Around 2017 | Non-revenue water measured at 46.8% | Structural problems were already serious |
| 2021 | Continuity 70.8% (about 17 h/day); losses described as very high | The system reached a severe operational low |
| 2023 | Large seasonal supply deficits still cited | Intervention had not removed the basic shortage |
| 2024 | Tanker distribution expanded during El Niño | Drought again exposed the same weakness |
| 2026 | Drought plan in May, main break in July, weekly line closures from September | The old deficit is under fresh pressure |

Are Santa Marta’s rivers giving the city less water?
Yes. In 2026 Santa Marta’s main river-fed treatment plants received less water, and that is hard evidence that the situation deteriorated.
ESSMAR reported on 28 May 2026 that inflow at Mamatoco had fallen from about 750 to 560 liters per second. That is a drop of roughly 190 liters per second, or about 25%. El Roble fell from approximately 500 to 450 liters per second, another 10% reduction.
Those numbers are especially important because Santa Marta depends heavily on the Manzanares, Piedras and Gaira river systems. Their flows vary considerably between wet and dry periods, and the city has no huge reservoir capable of smoothing that variation over long stretches.
Past droughts show how far the decline can go. ESSMAR reported during a previous severe dry period that flows in the Manzanares, Piedras and Gaira rivers had fallen close to 50%.
So when residents complained of low pressure and longer cuts in 2026, there was a measurable supply problem underneath. The treatment plants simply had less river water to work with.
Is Santa Marta simply running out of water?
No. Santa Marta still has several water sources, but the city cannot turn them into enough reliable tap water throughout the year.
The city draws surface water from the Manzanares, Piedras and Gaira systems and supplements those sources with groundwater wells. The surrounding Sierra Nevada receives substantial rainfall in parts of the year, while aquifers provide another source that can help when surface flows fall.
The problem appears when we follow the water from source to household. River flows can collapse during dry periods. Heavy rainfall can create another problem by pushing turbidity so high that treatment plants have to reduce output or stop temporarily. ESSMAR has had exactly that problem at Mamatoco, when muddy source water and landslides disrupted treatment, and on 5 September 2026 a Manzanares flood carried years of accumulated waste and plastic down to the bay.
Groundwater helps, but wells need pumps, electricity, maintenance and careful management of the aquifer. The distribution network then loses a very large amount of the water entering the system.
Santa Marta therefore has water around it while still struggling to deliver dependable potable water. That is why the city can face shortages during drought and treatment interruptions during intense rainfall.
Is Santa Marta wasting an extraordinary amount of its water?
Yes. Santa Marta still loses far too much water, and the scale is large enough to weaken almost every supply solution the city is considering.
A 2017 engineering study put non-revenue water at 46.8%. When ESSMAR was intervened in 2021, Superservicios described losses as very high. ANI's infrastructure portfolio (October 2025) still uses about 58% as Santa Marta's baseline and aims to bring it down to 27%.
The exact percentages are not perfectly interchangeable because non-revenue water includes several things: physical leaks, illegal connections, inaccurate meters and water that is supplied but never billed correctly. Still, a city operating around the high-50% range has an obvious efficiency problem.
The history is ugly. Going from 46.8% in the 2017 study to a 58% baseline in the 2025 plan suggests losses got worse, not better, although the two figures aren't measured the same way. This is not a system that has already fixed its network and simply needs another source.
The planned desalination plant makes the issue even more important. Desalinated water costs money and energy to produce. Sending expensive new water into a network with extremely high losses would leave a huge amount of value on the table.
| Measure | Earlier level | More recent baseline/target | What changed? |
|---|---|---|---|
| Non-revenue water | 46.8% around 2017 | — | Already very high |
| Losses around intervention | — | Described as very high in 2021 | No exact figure published |
| Current planning baseline | — | ~58% (ANI, October 2025) | Higher than the 2017 measure |
| Long-term target | — | 27% | Requires a major network overhaul |
70+pagesHas Santa Marta at least improved how many hours people get water?
Yes. Santa Marta appears to provide more hours of water on average than it did around the 2021 ESSMAR crisis, and that improvement deserves real weight.
Superservicios reported average continuity of 70.8% around the time of the intervention. That works out to roughly 17 hours of water service per day across the system. Some sectors were much worse, including areas receiving fewer than ten hours.
ANI's October 2025 infrastructure profile uses 20.5 hours per day as Santa Marta’s planning baseline. If we compare those figures cautiously, average continuity has improved by about 3.5 hours per day.
That is a meaningful gain. It is also one reason we would reject the idea that Santa Marta’s entire water system has simply become worse every year.
But averages hide some brutal local interruptions. A city averaging 20.5 hours can still have neighborhoods that go days without normal service when their part of the network loses pressure or when a major pipe fails.
So Santa Marta has made progress on average continuity while still failing a tougher test: can residents count on the water being there when the system is stressed? For many neighborhoods, the answer remains no.
Why does Santa Marta still need so many water tankers?
Santa Marta still relies heavily on tankers because the normal network cannot supply every neighborhood reliably during periods of scarcity.
The scale has been large for several years. During the 2024 El Niño emergency, the District said its Ruta del Agua program reached 161 neighborhoods and more than 40,000 families in one month through 2,103 tanker deliveries. On one reported day that year, ESSMAR delivered 1.824 million liters across 43 neighborhoods.
Alternative distribution stayed active in 2026. On 4 June ESSMAR said tankers and other alternative means had served 90 neighborhoods in the north and south over the previous three months. In October press reports still described sectors getting water once a week and families living off tanker trucks.
The same 4 June statement claimed more than 51 billion liters had been delivered through alternative means over three months. We would not use that figure literally. Spread over roughly 90 days, it would imply an average flow of more than 6,500 liters per second, far out of line with the scale of Santa Marta’s conventional water system and earlier tanker reports. The published figure likely contains a unit or transcription error.
The safer conclusion is simpler: emergency distribution has remained normal enough to have its own routing system, neighborhood prioritization and daily operating criteria.
A city can use tankers intelligently during a temporary emergency. Santa Marta has needed them too repeatedly for us to treat them as an occasional backup.
Is Santa Marta’s growth making the water shortage harder to fix?
Yes. Santa Marta is trying to close an old water deficit while the number of people and businesses demanding water keeps growing.
The size of the fix the government chose shows the size of the gap. In August 2025 the Ministry of Housing sized the main desalination plant, south of the city, at 600 liters per second, for a city that Superservicios puts at more than 650,000 people. The city does not need a few extra wells or a small pumping upgrade. It needs hundreds of additional liters every second.
Tourism makes the peaks harder. The airport handled 3.79 million passengers in 2025 (+4.7%) and its terminal is being expanded, the city fills up during holidays and festivals, while Rodadero, Bello Horizonte, Pozos Colorados and the wider southern corridor contain a dense concentration of hotels, apartments and tourism businesses.
ESSMAR’s own behavior shows that the tourism peak matters operationally. Before high-demand holiday periods, the utility performs preventive maintenance specifically to strengthen the water system. In December 2025 a new pump at Irotama increased distribution there from 140 to 178 liters per second for 8,262 users, installed explicitly to improve supply in the tourism corridor.
That 38-liter-per-second gain helps thousands of users, but it is about 6% of the 600 liters per second the planned desalination plant is meant to add.
Tourists did not create Santa Marta’s water crisis. They make an already tight system tighter during exactly the periods when demand jumps.
70+pagesAre broken pipes, illegal diversions and other disruptions now a major reason people lose water?
Yes. Santa Marta’s water network is so tight that a single damaged pipe or blocked intake can now remove water from tens of thousands of people.
The clearest example came on 15 July 2026. Third-party excavation damaged a 28-inch main carrying treated water from Mamatoco, and ESSMAR said 19,372 users across 58 neighborhoods were affected.
Around the same time, the Piedras intake was closed by a local community while Santa Marta was already dealing with low river flows. ESSMAR said the closure further reduced the amount of water entering Mamatoco.
Unauthorized interference has caused even larger shocks before. In July 2025, ESSMAR reported that an illegal blockage at the Manzanares intake cut approximately 350 liters per second, around 45% of the plant’s normal inflow, potentially affecting more than 96,000 accounts.
Other failures kept coming. On 30 August 2026 a transformer failure at the Rebombeo pumping station cut supply in 14 southern sectors, from Gaira and El Rodadero to Pozos Colorados and the airport. In September a main broken by third-party works on the Taganga road cut water in Nacho Vives. ESSMAR has also had to repair leaks on the Manzanares line and found more leaks during roadworks in the Zuana area.
We cannot prove from these examples that Santa Marta’s pipes are breaking more often than five years ago. What we can say confidently is that each failure carries an unusually high cost because the system has so little spare capacity. When supply is already short, losing another 100 or 300 liters per second hurts immediately.
| Recent disruption | Reported scale | Why it was serious |
|---|---|---|
| Damaged 28-inch main (15 July 2026) | ~19,372 users; 58 neighborhoods | Large central distribution line lost |
| Manzanares blockage (July 2025) | ~350 L/s | About 45% of normal Mamatoco inflow |
| Piedras intake closure (2026) | Reduced intake into Mamatoco | Happened during already-low river flows |
| Rebombeo transformer failure (30 Aug 2026) | 14 southern sectors | The pumping chain for the whole south stopped |
| Network leaks | Multiple local repairs | Adds losses to an already inefficient system |
Is Santa Marta’s tap water becoming less safe?
No. Santa Marta’s official drinking-water quality has actually improved, and scarcity is a much clearer problem today than declining potability.
Water quality was one of the concerns around the period that led to ESSMAR’s intervention. Superservicios reported samples above the 5% IRCA threshold during 2019 and 2020, meaning the water did not consistently remain in Colombia’s “without risk” category.
That picture improved afterward. ESSMAR reported IRCA readings below 5% from late 2022 onward, and on 1 July 2026 it repeated that the city’s water had stayed below the 5% threshold, based on 70 sampling points agreed with the health department.
We should still distinguish treated tap water from raw river water. Research on the Gaira and Manzanares systems has found microbial contamination and other water-quality pressures in the rivers themselves. Those findings matter for people using untreated sources and for the amount of treatment required at the plants.
They do not show a current citywide decline in the quality of properly treated water leaving ESSMAR’s system.
For now, Santa Marta’s bigger water risk is whether enough treated water reaches residents consistently.
Is Santa Marta fixing the existing water system fast enough?
No. Santa Marta has more repair and upgrade work underway than before, but the improvements are still too small compared with the size of the underlying shortage.
There has been tangible progress. ESSMAR has maintained and upgraded Mamatoco and El Roble, repaired distribution lines, raised the Irotama pumping station from about 140 to 178 liters per second in December 2025 and, in May 2026, was bringing five wells back into service to add more than 100 liters per second.
The scale is the problem. Irotama added 38 liters per second and the wells about 100; the plant the government designed to close the gap is 600. Together, the visible recent upgrades come to under a quarter of that.
The same problem appears with losses. ANI's plan still uses a baseline close to 58% and envisions cutting it to 27%. That kind of change requires extensive sectorization, metering, leak detection, replacement of old pipes and stronger control of unauthorized connections.
Santa Marta is finally spending effort on several parts of the system at once. The city simply has not reached the point where those projects change daily water security for everyone.
70+pagesWill Santa Marta’s desalination plant finally solve the water crisis?
The desalination plant could remove a large part of Santa Marta’s supply shortage, but residents should not count it as solved water until the plant is built, connected and operating.
The planned scale is large enough to matter. In August 2025 the Ministry of Housing described a 600-liter-per-second plant south of the city plus a small 11.5-liter-per-second unit for Taganga, with COP 773 billion (about $242 million) for desalination, 70% from the national government and 30% from the city.
For scale: 600 liters per second is more than the whole inflow Mamatoco was getting at the low point of the May 2026 drought (560).
Then it stalled. The Ministry of Housing announced on 19 June 2026 that the selection process was starting, with ESSMAR structuring it and land from the city. On 28 July the Procuraduría asked for a provisional suspension of a large drinking-water supply contract process, and on 19 August ESSMAR said it had no desalination tender, award or contract running.
In October 2026 a former superintendent started collecting 50,000 signatures to protect about COP 786 billion (about $246 million) earmarked for the city’s water. Money set aside is not a plant: design, construction, testing and connection to the network are all still ahead, and today the plant adds zero liters per second.
There is another catch. New production will work much better if Santa Marta also repairs the network. A system starting from losses near 58% can burn through a surprising share of additional capacity before residents feel the full benefit.
| Project or measure | Approximate scale/status | What residents get today |
|---|---|---|
| Main desalination plant | ~600 L/s planned (MinVivienda, Aug 2025); no tender or contract (ESSMAR, 19 Aug 2026) | No operating supply yet |
| Taganga desalination project | ~11.5 L/s planned (MinVivienda, Aug 2025) | Future local capacity |
| Irotama pump upgrade | 140 → 178 L/s (December 2025) | Already operating |
| Well rehabilitation | Five wells, 100+ L/s (May 2026) | Incremental support |
| Network loss reduction | Target from ~58% to 27% | Still largely unfinished |
Did almost five years of government intervention actually fix ESSMAR?
Partly. ESSMAR is in better shape than when the national government took control, but Santa Marta still has a water crisis after almost five years of intervention.
Superservicios intervened ESSMAR in November 2021 after finding serious technical, financial and service problems. Average continuity was 70.8%, losses were very high, the water-quality risk was rated medium and the utility faced a cash deficit of about COP 62 billion.
The intervention ended in August 2026. On 11 August Superservicios announced it had returned ESSMAR to Santa Marta’s municipal administration after concluding that the District’s rescue plan was technically, financially and legally viable.
That is a real institutional improvement. Water quality has also moved into the official low-risk range, average continuity appears better and several infrastructure projects advanced during the intervention.
But look at the timing of the handover. ESSMAR returned to local control while the city was again dealing with a dry-season emergency, falling river flows and alternative water distribution. Superservicios also kept the company under special supervision for six months, until about February 2027.
So the intervention helped stabilize ESSMAR as a company. It did not deliver enough new water infrastructure to end Santa Marta’s recurring shortages.
Could fixing Santa Marta’s leaks help almost as much as finding another water source?
Potentially, yes. Cutting Santa Marta’s water losses could recover a huge amount of value from water the city already produces, although we cannot treat the entire 58% loss figure as physical leakage.
The planned reduction from roughly 58% non-revenue water to 27% equals 31 percentage points of system input. Even without knowing the exact current production volume on every day, the scale is enormous.
Some of that 58% comes from actual leaks. Recovering those liters directly improves physical supply. Another part comes from illegal connections, faulty meters and water that reaches users without generating proper billing. Fixing those losses mainly improves ESSMAR’s finances, which still matters because a financially healthier utility can maintain and expand the system more effectively.
Recent events show both sides. ESSMAR has repaired leaks on the Manzanares system, while illegal interference has previously removed hundreds of liters per second from major intakes.
The best outcome would therefore combine new supply and lower losses. Desalination gives Santa Marta another dependable source; network repairs make sure more of that expensive water reaches paying users.
70+pagesIs climate change making Santa Marta’s water problem harder for good?
Probably yes. Santa Marta’s water system is becoming riskier to operate because it depends heavily on sources that respond quickly to heat, rainfall and drought.
Research and climate-resilience projects around the Sierra Nevada have long warned that higher temperatures and changing rainfall could reduce dependable water availability around Santa Marta. The precise long-term decline varies between models, so we should avoid pretending there is one certain percentage.
What we can observe already is the vulnerability those models describe. River flows have fallen dramatically in previous droughts. In May 2026 flows into Mamatoco and El Roble declined again. In August IDEAM expected El Niño to last into early 2027 and possibly become very strong, with below-normal rain for most of the Caribbean region through December and above-normal temperatures.
Heavy rain brings a different problem. Intense precipitation can drive turbidity high enough to interrupt treatment, and the 5 September 2026 Manzanares flood showed how much debris the river can bring down. Santa Marta therefore has to manage both ends of the climate problem: too little river water during dry periods and difficult-to-treat river water during extreme rainfall.
The city’s long-term projects increasingly reflect that reality. Desalination, groundwater management, lower leakage and a more redundant distribution network all reduce dependence on exactly how much rain falls over the Sierra Nevada in a particular season.
Is Santa Marta closer to fixing its water problem than five years ago?
Yes. Santa Marta is much closer to a credible long-term solution than it was five years ago, even though residents still live with a system that can fail badly today.
Five years ago, ESSMAR was entering national intervention with continuity around 17 hours a day on average, losses the regulator called very high and no near-term solution capable of fundamentally changing the supply balance.
Now several pieces are further along. Average continuity appears higher. Water quality has improved. The desalination plant has a site and money earmarked, even though its selection process stalled in 2026. Pumping upgrades are operating. Well rehabilitation and network work continue. ANI's much larger long-term concession plan targets 24-hour continuity, full water coverage and losses of 27%.
The ambition of that broader plan is huge. National infrastructure documents estimate around COP 6.14 trillion (about $1.92 billion, in 2024 pesos) of investment for the long-term acueducto and sewer overhaul, with water coverage intended to rise from around 83% to 100%.
But there is still a wide gap between planned infrastructure and delivered water. Most of the transformative capacity has not reached the network yet.
Santa Marta is closer to solving the crisis on paper and in budgets. Residents will know the situation has really changed when a strong dry season no longer pushes large parts of the city back toward tankers, low pressure and rotating shortages.
| Structural issue | Current/planning baseline | Long-term objective | Progress so far |
|---|---|---|---|
| Water coverage | ~83% | 100% | Large gap remains |
| Average continuity | ~20.5 h/day | 24 h/day | Meaningful improvement |
| Water losses | ~58% | 27% | Still far from target |
| Additional supply | 600 L/s desalination plant designed | Diversified new supply | No contract yet |
| Utility governance | Intervention ended August 2026 | Stable local operation | Improved, under special supervision for six months |
What happened to Santa Marta's water between July and October 2026?
A lot, and none of it good news for anyone hoping the crisis was fading. The 28-inch main break on 15 July hit 58 neighborhoods. On 30 August the Rebombeo transformer failed and the whole southern corridor lost pressure at once.
On 16 September ESSMAR started closing the Manzanares supply line every week, from Tuesday 4 p.m. to Friday 6 a.m., so more river water reaches the Mamatoco plant. Homes hooked directly onto that line, many of them irregular connections, go without water for those days.
In October press reports still described sectors receiving water once a week, and a former superintendent launched a drive for 50,000 signatures to protect about COP 786 billion (about $246 million) earmarked for water. The desalination plant, meanwhile, had no tender or contract.
| Date (2026) | Event | Who felt it |
|---|---|---|
| 28 May | Drought plan: Mamatoco inflow 750 → 560 l/s | Citywide |
| 15 July | 28-inch main damaged | 19,372 users in 58 neighborhoods |
| 11 August | ESSMAR handed back to the city | Six months of special supervision |
| 19 August | ESSMAR: no desalination tender or contract | Everyone waiting for new supply |
| 30 August | Rebombeo transformer failure | 14 southern sectors |
| From 16 September | Weekly Manzanares line closure | Direct connections on the line |
70+pagesWhat does Santa Marta's water problem mean if you're buying property?
Mostly, that you are buying a building's water system as much as an apartment. The priciest areas sit on the weakest part of the network: Colombia Bound's September 2026 asking medians put Bello Horizonte at about US$3,438 per m², Pozos Colorados at US$3,381 and Playa Salguero at US$3,151, against US$1,838 in El Rodadero. All of them were on ESSMAR outage lists in 2026.
Foreign buyers carry more of this risk here than elsewhere: in Magdalena, foreign non-residents bought 7.3% of new homes sold, against 2.1% nationally (Camacol, December 2025).
Storage costs money every month too. Nationally, building administration fees rose 17.14% in the year to September 2026 (DANE), and in Santa Marta part of that bill is pumps, tank cleaning and trucked water.
Our advice: value the property as if today's supply lasts for years, and pay nothing extra because an agent says desalination is coming. If the administration can't give you the numbers below, negotiate as if you'll be paying for tankers.
| What to ask the administration | Good answer | Red flag |
|---|---|---|
| Cistern capacity and units sharing it | Stated in cubic meters | "Big enough" |
| Days of autonomy without ESSMAR | Two days or more | A few hours |
| Tanker deliveries paid in 2026 | Rare, invoiced | Regular, as a cuota extraordinaria |
| What happened on 15 July and 30 August 2026 | Taps kept running | Residents went without water |
| Backup pumps and power | Redundant, maintained | One aging pump |
So, is Santa Marta’s water problem getting worse?
Yes, Santa Marta’s water problem is getting worse in the sense that matters most right now: the city’s already-tight supply is facing stronger pressure before its major new infrastructure is ready.
River inflows into the main treatment plants fell in May 2026. El Niño strengthened through August. ESSMAR used alternative distribution across dozens of neighborhoods and, since September, shuts a main supply line every week. A single damaged pipe or blocked intake can remove water from tens of thousands of users because the system has little spare capacity.
At the same time, Santa Marta has improved some things. Average continuity is higher than around the 2021 intervention, official water-quality indicators are better and ESSMAR has returned to local control. Those gains are real, and ignoring them would exaggerate the decline.
They just have not changed the central water equation enough.
The strongest number remains the gap between what Santa Marta has and what it needs. The plant designed to close it, 600 liters per second, had no tender or contract as of 19 August 2026. Network losses, meanwhile, remain around 58% in the city’s infrastructure planning baseline.
So the sharper answer is not that Santa Marta is simply “running out of water.” The city has made operational progress while its overall water security has become more exposed. The 2026 drought arrived faster than the new supply, lower losses and redundancy needed to handle them.
Until that balance changes, another severe dry season will keep producing the same familiar result: less water in the rivers, more pressure on a fragile network and too many neighborhoods depending on emergency distribution.
Our methodology
This analysis tests whether Santa Marta’s water problem is getting worse by splitting it into parts: river supply, climate, network losses, hours of service, drinking-water quality, tanker use, infrastructure failures and new supply projects. One bad outage or one improving indicator was not enough to answer the question.
We gave priority to dated ESSMAR operating notices from 2025 and 2026 (May drought plan, July main break, August Rebombeo failure, September weekly closures, the 1 July water-quality statement and the 19 August desalination statement), Superservicios documents on the 2021 intervention and the August 2026 handover, and IDEAM's August 2026 El Niño outlook.
For the long-term picture we used ANI's October 2025 infrastructure portfolio (58% loss baseline, 20.5 hours of continuity, 83% coverage, COP 6.14 trillion plan in 2024 pesos), the Ministry of Housing's August 2025 desalination plan (600 l/s plus 11.5 l/s for Taganga, COP 773 billion) and a 2017 engineering study for the 46.8% non-revenue-water baseline. These figures don't form one clean time series, so we compare them with care.
Planned capacity is not water. The desalination plant counts as zero supply until it is contracted, built, connected and running; as of 19 August 2026 ESSMAR said there was no tender, award or contract. Where an official figure looked inconsistent with the size of the system (the 51 billion liters of tanker water), we did not use it, and we did not reuse older deficit percentages we could not trace to a current official source.
Price-per-m² figures come from Colombia Bound's September 2026 neighborhood asking medians, the foreign-buyer share from Camacol (December 2025) and the administration-fee increase from DANE's September 2026 CPI.
We checked these figures in October 2026. Dollar amounts use about COP 3,190 per US dollar (official TRM of 22 October 2026).
Limits: ESSMAR notices list affected sectors but rarely say how long each was without water, and no official neighborhood-by-neighborhood continuity figure exists. A given building can do much better or worse than its street.
