Despite the significant rainfall in recent days, the water shortage in the Messara Plain remains dramatic, and how desalination projects are set to save Greek islands.
Messara: Just a drop in the ocean
The rains of recent weeks have brought water, but the situation remains critical for the Messara Plain.
The Faneromeni reservoir is filling slowly.
It currently holds just 3.5 million cubic metres, and perhaps by the end of the water year it will hold four million.
That may sound like a lot, but with a total capacity of 18 million cubic metres, it is actually only a fraction.
The region needs water – for tourism, but above all for agriculture.
Messara is home to large vegetable and fruit farms, as well as countless greenhouses.
These areas depend on reliable irrigation.
If the reservoir volume remains below certain thresholds, it is only just enough to provide emergency supplies to the driest areas.
This is not nearly enough for the regular irrigation of larger areas.
The administration and local authorities are sounding the alarm.
Without additional infrastructure, the situation will remain tense in the long term.
They say quite openly that rain alone, without significant snowmelt and without more storage capacity, is simply not enough to fill a large reservoir like Faneromeni.
The current water level speaks for itself.
The only real hope is a new dam project on the Platy River.
This should create additional storage and stabilise water distribution.
Planning is already underway – ownership regulations, land clearance, the first steps have been taken.
As soon as that is done, the tender will be issued.
After that, construction work could begin, but even if everything goes smoothly, experts estimate that it will take around six years to complete.
Until then, the Faneromeni reserve will remain the central buffer.
The reserves only allow for limited water expenditure.
Internal regulations set a critical threshold at around six million cubic metres.
Only then will there be enough water for large-scale irrigation.
If the reserves fall below this level, only the driest areas will receive water – simply to save the harvests.
This means that agricultural businesses are facing conditions that are quite difficult to plan for.
Irrigation plans, investments in crops, labour – everything depends on water, and that is uncertain.
Many operators are trying to save where they can: they are reducing the area under cultivation, relying on less water-intensive varieties or investing in drip irrigation.
This helps, but it does not replace a lack of storage.
Tourism is also feeling the effects of the situation.
Hotels and holiday homes need a constant supply of water – for guests, swimming pools and green spaces.
Water restrictions reduce the quality of life for visitors and damage the region’s reputation.
Greater uncertainty regarding water means higher operating costs, for example due to additional tanks or expensive deliveries.
Ultimately, this affects the services on offer and sometimes even customer service.
Local decision-makers and water authorities are currently working on short-term measures.
These include new distribution concepts, stricter controls on water extraction and emergency plans for dry periods.
The aim is to stabilise the situation until larger construction projects can get underway.
But let’s be honest, these are all just temporary solutions.
Without sufficient storage, the region remains vulnerable.
The planned dam on the Platy River could fundamentally strengthen the hydrological basis of Messara.
It would better capture rainfall, compensate for seasonal fluctuations and allow for more reliable allocation for irrigation.
This would make agricultural planning more secure and investments in high-quality production more worthwhile.
A larger storage area would also help to better withstand dry years.
However, there is still a long way to go before construction can begin.
First, ownership issues must be clarified and land made available.
Then come the tendering process, planning and finally the construction phase.
Even if everything goes smoothly, this will take several years.
This timeframe is forcing local stakeholders to find temporary solutions and become even more efficient in their water consumption.
One point that is often overlooked is the social impact.
Many families in Messara live directly or indirectly from agriculture.
When water is scarce, production declines – threatening incomes and livelihoods.
This social dimension makes the search for quick and reliable solutions even more urgent.
Technical measures alongside large-scale storage are also on the list.
Better pipes, fewer losses due to leaks and more modern irrigation technology should make more efficient use of the available water.
Support programmes for farmers could help to reduce the burden in the short term.
However, this requires money and coordination at the administrative level.
Here are a few figures for an overview:
- Current reserves: approx. 3.5 million m³
- Expected reserves by the end of the water year: approx. 4 million m³
- Total capacity of the Faneromeni reservoir: 18 million m³
- Critical release level for irrigation: 6 million m³
- Estimated construction time for Platy dam: at least 6 years
No wonder the local leadership considers the construction at Platy to be essential.
Even if the rain cooperates, there will still be a real deficit without additional storage.
Coordination between regional authorities, agriculture and communities is crucial.
Measures will only be effective if they are implemented quickly and accepted by all.
Information campaigns, transparent rules and clear priorities help to avoid conflicts.
Investors and sponsors have long been examining feasibility and costs.
A project like this needs planning security and long-term commitments.
Private-public partnerships or government subsidies could make it all happen.
But how the climate and rainfall patterns will develop remains an open question.
Until construction begins at Platy, Faneromeni must continue to catch everything.
Even in years with moderate rainfall, there is no real protection against water shortages.
The authorities are fighting for every cubic metre to save crops and keep the economy going.
In the short term, prioritising drinking water, restricting unnecessary discharges and providing targeted support for small businesses could help.
In the medium term, additional storage capacity remains the most important lever.
Without this investment, there is a risk of recurring crises with severe consequences for Messara.
Experts emphasise the importance of networking and regional cooperation.
The project is located on the border with the administrative district of Rethymno, so supra-regional coordination is needed.
Water does not respect administrative boundaries – all stakeholders must pull together to make a new reservoir work.
The consequences of the current water shortage are by no means limited to irrigation.
Plant selection, harvest times and investment decisions also depend on it.
Many farms are wondering whether to continue investing in water-intensive varieties or whether to switch to something else.
All this is changing not only the landscape but also the local economy.
The authorities are looking for alternatives to bridge the gap until construction is completed.
These include temporary water transfers, the use of underground reserves and water recovery programmes.
These measures are expensive and usually have only a limited effect.
A large reservoir that cushions seasonal fluctuations simply cannot be replaced.
Political pressure and public attention are helping to speed up the project.
Local representatives are putting considerable pressure on the ministry.
If approvals, tenders and planning proceed quickly, the chances of the project actually happening increase.
But there is still a long way to go before completion.
In the meantime, municipalities, businesses and water authorities are looking for ways to mitigate the impact.
They are setting priorities, investing in efficiency and trying to adapt production to less water.
This requires courage and organisation, but it also brings opportunities.
Those who invest in economical technology now will work more cheaply and in a more environmentally friendly manner later.
The Messara region faces a clear task: crisis management now and investment in infrastructure for tomorrow.
Both must run simultaneously.
Without the new reservoir at Platy, the region remains vulnerable.
With it, there is a chance for stable irrigation, predictable agriculture and secure livelihoods for many families.
Island desalination projects strengthen water supply
The government has approved many water supply projects. The aim is to close gaps caused by drought.
Funds are flowing into numerous projects. Some are expanding existing networks, others are tapping new sources and using modern technology.
Three islands are getting desalination plants for the first time: Andros (600 m³/day), Kea (200 m³/day) and Meganisi (600 m³/day).
Meganisi was already in a state of emergency due to water shortages. The new plants are intended to secure the basic supply there.
Other islands in the Aegean and Ionian Seas are also receiving support so that they can produce more drinking water.
Islands receiving funding (excerpt):
- Cyclades: Kythnos, Naxos, Amorgos, Folegandros
- Dodecanese: Karpathos, Leros, Patmos
- Northern Aegean: Chios, Fournoi
- Sporades: Alonnisos
- Saronic Gulf: Spetses, Poros
- Ionian Sea: Paxoi, Ithaca, North Corfu
Desalination and drilling projects are also planned on the mainland. This affects several regions of the Peloponnese, Central Greece and Crete, for example.
In Volos, people are now making better use of local sources.
At the same time, they are modernising water networks in towns and municipalities. These include Hydra, Serres, Kymi, Aktio, Pylaia and Central Corfu.
Advantages of the measures:
- Rapid relief in the event of acute water shortages
- Better security of supply for tourist and residential areas
- More flexible combination of permanent and mobile facilities
Funding comes from a sectoral development programme. Many projects are already in the starting blocks and will soon be put out to tender.
