Waterschap Zuiderzeeland has proposed raising its 2027 water board tax rates by more than 9%, citing rising costs for maintenance, investment and energy. The proposal would increase the annual bill for a multi-person homeowner from €503.53 to €551.43, an increase of €47.90. Tenants, single-person households and businesses would also pay more, with proposed increases of 9.6% for agricultural holdings and 10% for industrial companies.

The proposal comes after a similar increase for 2026. The water board said the additional revenue was needed for renewing infrastructure, strengthening dikes, improving freshwater availability, and preparing for power failures and cyberattacks. The general administration will decide on the proposal on 26 November; the rates are not yet final. The water board’s multi-year estimate also anticipates annual increases in water system charges between 2028 and 2031. A remission scheme for residents unable to pay will be extended from 2027.
