€160M Plan Aims to Secure Drinking Water for Alentejo Communities

A €160 M investment package, unveiled this month by Environment and Energy Minister Maria da Graça Carvalho, promises to overhaul ageing water networks, treatment plants and supply lines in the drought-prone Alentejo. The announcement is being greeted with cautious optimism by local councils that say the cash is welcome but still short of what is needed to future-proof Portugal’s hottest and driest region.

Snapshot

• Total budget: €160 M under the second phase of the Programa Operacional Sustentável 2030

• Priority areas: Santa Clara–Odemira, Alvito–Cuba–São Matias, Grândola–Melides, Alcácer do Sal–Santiago do Cacém, Moura and São Luís

• Main goals: secure drinking water, swap obsolete pipes, modernise ETARs at risk of EU non-compliance, add solar power to plants, cut energy bills

• Funding mix: up to 85 % FEDER co-financing, topped up by the national Fundo Ambiental for smaller quick-win projects

Why It Matters for Portugal

Recurring heatwaves have pushed Alentejo’s rainfall deficit close to 30 % below the national average over the past decade. Coastal hubs like Odemira host intensive farming and seasonal tourism, multiplying water demand. By targeting critical supply corridors and failing treatment stations, Lisbon hopes to avoid EU infringement proceedings and soften the economic impact of future droughts felt on dinner tables across the country.

Where the Money Will Flow

The star project is the 56 M€ revamp of the Santa Clara system, including a brand-new Water Treatment Plant in São Teotónio and nearly 20 km of new conduits from the Santa Clara dam. Further south, reservoir and pipeline upgrades in Alvito, Cuba and São Matias aim to cut leakage that currently runs above 28 %. Along the coast, the second phase of the Grândola-Melides adduction and a full remodelling of networks serving Alcácer do Sal and Santiago do Cacém will improve reliability for 80 000 residents. Smaller but urgent repairs at the Moura and São Luís ETARs round out the first batch of contracts.

Who Is Picking Up the Bill?

Brussels will bankroll the bulk through FEDER envelopes re-programmed in December 2025 under Alentejo 2030. Each project can claim up to 85 % EU co-financing, leaving municipalities and the state to cover the remainder. For fixes under €3 M, the government will tap the Fundo Ambiental, allowing faster procurement and fewer reporting obligations—a manoeuvre applauded by cash-strapped councils that struggle to meet EU paperwork demands.

Local Voices: Enthusiasm Meets Skepticism

Mayors grouped in the Associação de Municípios para a Gestão da Água Pública (AMGAP) praise the government for finally targeting the worst bottlenecks, yet warn that their own needs assessment tops €250 M. “We cannot afford another summer of water trucks and emergency pipes,” said AMGAP chair Marcelo Guerreiro, calling for legally binding schedules. Agricultural cooperatives welcome the Santa Clara focus but lobby for broader irrigation upgrades, while environmental NGOs argue that industrial farming must also commit to water-saving technology to avoid repeating past shortages.

Timeline and Next Steps

Public tenders for the Santa Clara package go live in March, with ground-breaking expected before the 2026 irrigation season. Remaining design studies should be cleared by autumn so that all contracts are signed ahead of the EU funding window that closes in 2027. The ministry has pledged quarterly dashboards so residents can track progress online.

Key Takeaways for Residents

When skimmed, three messages stand out: substantial EU money is finally arriving, the first shovels go into the ground this year, yet local leaders insist that €160 M is only a down-payment on Alentejo’s long-term water security.
