The Five Strategic Pillars
-
Architectures: State-owned bulk system governance
Maps how Águas de Portugal structures mainland water supply and wastewater responsibilities through operating subsidiaries while municipalities retain the retail layer.
-
Enablement: PENSAARP 2030 delivery framework
Explains how national planning objectives, priority measures and sector investment needs convert climate resilience into a structured delivery agenda.
-
Resolution: Drought-driven supply diversification
Assesses how the Algarve desalination project creates a practical supply-diversification signal for climate-exposed regions facing water scarcity.
-
Alignment: European compliance pressure
Connects wastewater treatment obligations, regulatory enforcement and infrastructure investment to the Group's near-term capital priorities.
-
Capability Building: Digital loss-control and energy discipline
Evaluates WONE, waterbeep, Billmeter and ZERO Energy Neutrality Programme evidence as operational tools for measurable resilience improvement.
Operational Excellence & Resilience
Águas de Portugal operates an integrated water network supported by state-owned bulk supply and wastewater systems across mainland Portugal. Performance is achieved through WONE monitoring and control zones that use flow and pressure analytics for water-loss control. This is further supported by waterbeep customer consumption information and Billmeter metering-error loss control. Key performance is reflected in 191 million cubic metres of water wasted nationally in 2023, highlighting the sector efficiency challenge. This is reinforced by about 2.8 MW of annual photovoltaic production at Alcântara, Beirolas and Chelas.
The EUR 500 million EIB loan, approved on 18 December 2025 within a EUR 1,127 million total project cost, funds Águas de Portugal's 2025-2029 programme for construction and rehabilitation of bulk and retail water supply systems and wastewater collection and treatment across mainland Portugal. The programme supports compliance with the EU Water Framework Directive and Urban Waste Water Treatment Directive while sitting inside the wider PENSAARP 2030 national planning frame for the 2021-2030 period.

Expert Briefing: FAQs
The programme is anchored by European Investment Bank financing for Águas de Portugal. This is supported by a EUR 500 million loan within a EUR 1,127 million total project cost. This is delivered through the 2025-2029 investment programme for mainland water supply and wastewater systems.
PENSAARP 2030 provides the national planning framework for the utility's resilience agenda. This is supported by four global objectives, 20 specific objectives and 85 measures. This is delivered through Council of Ministers Resolution No. 23/2024 for the 2021-2030 planning period.
The Algarve desalination plant is the clearest supply-diversification evidence. This is supported by planned production of about 16 million cubic metres per year, extendable to 24 million cubic metres. This is delivered through the Águas do Algarve design-build-operate contract awarded on 22 October 2024.
The report identifies digital loss-control and energy-efficiency programmes within Águas de Portugal. This is supported by about 2.8 MW of annual photovoltaic production at Alcântara, Beirolas and Chelas. This is delivered through WONE, waterbeep, Billmeter and the ZERO Energy Neutrality Programme.
