Gouda floodgate

Commissioned by the Rijnland Water Authority, Aannemingsbedrijf G. van der Ven is renovating the monumental Keersluis lock. This project will make the lock future-proof and bring it into line with current water safety requirements, while retaining its historic appearance from 1931.

Work will start in February 2026 and will take approximately one and a half years to complete. Van der Ven will repair concrete and natural stone structures within a watertight construction pit, replace the lock gates, and renew the fencing and railings. By working in phases, the pumping station will remain operational during the renovation.

This is a project that combines water safety, craftsmanship, and careful handling of historical heritage.
