Executive overview
Key findings
95 → 107 million m³ a year: Waternet's regular production capacity in 2024 against the capacity required by 2030 (projection)
122 million m³ a year: capacity required by 2050 in the 2023 forecast; the 2024 update adds about 4 million m³ a year after 2030
70 → 75 million m³ a year: dune abstraction ceiling, raised on 13 August 2025 after demand growth and extra deliveries to neighbouring utilities threatened to exceed it
141 litres: water use per person per day in the Waternet supply area in 2021, against a national target of 100 litres by 2035

Buyer relevance
Who the report is for
Large water users and data-centre developers
Gauge supply risk before relying on drinking water, given permits such as about 1.1 billion litres a year for two planned Equinix data centres.
Water sector consultants and engineers
Follow the post-2030 options, including about 6 million m³ a year of brackish seepage from the Horstermeerpolder that needs membrane treatment.
Provincial, city and national policy teams
See which intake, permit and demand decisions set the supply balance after 2030 and the national 100-litre target.
Investors and analysts covering Dutch utilities
Assess how a 5% operational reserve and a 2030 shortfall of 10 against 14 million m³ a year affect Waternet's risk.
03
Decision scope
Questions answered
Does Amsterdam have enough drinking water capacity today?
Regular capacity is 95 million m³ a year with a 5% reserve; the required capacity rises to 107 million m³ a year by 2030.
Where will new supply come from before 2030?
From +5 million m³ a year at the Leiduin dunes and +5 through a new bulk supply from PWN, 10 million in total; a further +6 at Weesperkarspel is expected in use in 2031.
Is there enough new supply after 2030?
The named options add about 30 million m³ a year if all deliver in full, against a forecast post-2030 need of about 15 to 19 million.
How much water do residents use?
141 litres per person per day in the Waternet supply area in 2021, against a national target of 100 litres by 2035.
