Water supply in Heraklion at a critical point, and there are few encouraging signs in western Crete either.
Water Supply Situation in Heraklion
Heraklion’s got a serious water supply problem after damage hit the main equipment in the Apselemi network. The top priority is to fix this mess and get water flowing again.
They probably won’t reach the agreed supply levels for August, but at least they want to match what the city had earlier in the summer. Everyone’s wondering if there’s any backup plan if things stay broken.
Do city leaders have a Plan B, or are people just stuck with the consequences? It’s become a pretty urgent issue, with major concerns about the future of Heraklion’s water.
Over the past few years, water reserves have just gotten worse. Long dry spells and poor rainfall have really pushed the system to its limits.
The Apselemi dam, once a dependable source, now looks shaky. Even though it’s a big dam, it can’t keep up during these repeated droughts.
Eastern Crete is getting dangerously close to the point where water shortages might stick around for good. In 2021 and 2022, things briefly looked better thanks to some heavy rain.
The dam filled up, so the city avoided the worst restrictions. Back then, the region needed about 20 million cubic metres a year, split about half and half between the dam and local wells.
There’s also around 1 million cubic metres a year from a private desalination plant. That helps, but it’s just a drop in the bucket compared to everything else.
So, dam water and well water were pretty balanced during those rare years with decent rainfall. But starting in 2022, that changed.
The dam only gave 6.5 million cubic metres, and wells had to step up to 12.5 million. Suddenly, groundwater had to cover the shortfall.
By 2024, wells were doing even more of the heavy lifting. They provided 15.5 million cubic metres—about 77.5% of the total.
The dam? Just 3.5 million, not even a fifth of what’s needed. Looks like this trend isn’t going away, either—over 80% of water will come from wells and desalination combined.
This puts a lot of strain on the wells. Pulling so much groundwater isn’t exactly a sustainable plan, and it could mess with local ecosystems.
The city’s basically running the wells flat out, hoping the dam bounces back. If it doesn’t, they’re in trouble.
Experts are crossing their fingers that repairs on the Apselemi network wrap up soon. If not, things could get ugly fast.
There’s no real backup plan for Heraklion’s water system, which is honestly kind of scary. If repairs flop or droughts keep hitting, the city could face a major crisis.

The table lays it out: the dam just isn’t pulling its weight anymore, so wells have become the main source. This shift is kind of alarming if you ask me.
The pressure on natural resources keeps climbing, and relief doesn’t seem close. Authorities really need to step up and do something.

Pumping Mud Instead of Water: Aposelemi Dam Near Collapse – Emergency in Eastern Crete
The water level at the Aposelemi Dam has dropped to an alarming low. Instead of clean water, the dam mostly pumps mud now.
Several municipalities in Eastern Crete depend on this dam, so things are tense. The region’s basically on high alert, with basic water needs at risk.
The Crete Development Organisation (OAK) says the dam’s water volume is at a critical point. There’s only about 3.5 million cubic metres or less left.
At this stage, the system pulls water from the very bottom, so a lot of sediment and mud gets sucked in. That makes the water undrinkable.
The treatment system can’t handle it. The worse the raw water gets, the harder it is to clean.
They’re trying to upgrade the treatment tech, but honestly, there’s only so much it can do. Right now, the amount of drinkable water is way below what the towns need.
Local leaders from Heraklion, Hersonissos, and nearby areas are demanding action. They’re calling on the government to step in and hand dam management over to the municipalities.
They argue OAK just isn’t moving fast enough. Residents are dealing with daily water shortages, and it’s wearing people down.
Public officials warn that if things don’t change, the dam could completely fail to supply water. The risk of a total collapse is real.

This drop in clean water hits a lot of people. Municipalities in Eastern Crete have lost nearly 40% of their usual supply.
Local leaders are bracing for even worse shortages if things don’t turn around soon. The dam’s running on fumes.
It’s a constant struggle just to keep water service going. The need for a new management plan is obvious at this point.
Without quick action, the water crisis could spiral, hurting homes and businesses. Local and central authorities are watching the situation closely.
There’s a growing push to put local management in charge, since people hope that means faster and better responses. If you want the latest updates, there’s more info on the dam’s current status.
The false idea that western Crete has abundant water – Drought hits the entire island hard
People often think western Crete, with all its green hills, lakes, and springs, has endless water. That’s just not true.
Sure, eastern Crete gets attention for water shortages, but western areas are also running low. It’s not just a local issue—water scarcity stretches across the whole island.
In the last 18 months, nine municipalities have asked for emergency status because of drought. Farmers in spots like Ierapetra and the Mesara plain worry about their land turning into desert.
Meanwhile, some folks at home are left with dry taps. Not exactly the picture of abundance people imagine.
Western Crete now shows obvious signs of climate change hitting water resources. Underground reserves keep shrinking, and water quality isn’t what it used to be.
Honestly, the island waited too long to get serious about protecting its water. When action finally started, it felt a bit late.
Places like Rethymno and the north of Mylopotamos already feel the squeeze. They’ve just begun work on a new Water Treatment Plant at the Potamoi Dam.
This project should eventually bring 30,000 cubic metres of water per day to those towns, but that’s still about three years away. Until then, folks have to make do.
Right now, people are over-pumping from Lake Kournas to keep up with demand. At the same time, nearby springs have lost about half their usual flow.
That’s made things worse. Even with these stopgaps, water shortages keep biting into daily life and farming.
Eastern Crete is still in a tough spot, especially around the Aposelemis dam. Water problems there ripple through several municipalities and keep everyone talking—and worrying.

The drought keeps putting strain on agriculture, water supply, and local ecosystems. Unless there’s a real push for better planning and smarter management, dry conditions probably won’t let up anytime soon.
Building new infrastructure and using water more wisely? That’s not just a good idea—it’s starting to feel urgent. The water shortage issue in Crete isn’t going away by itself.
