The objective is a durable, watertight replacement that meets the safety and quality requirements for drinking water infrastructure, with minimal disruption to service. The assignment requires a structural engineer with experience in water infrastructure, knowledge of concrete and waterproofing systems, and the ability to deliver within the specified time and budget.
At its Hoorn distribution pumping station, located at Leekerpad 1689PB in Zwaag, PWN has six drinking water cellars for the storage of drinking water for the region. Drinking water cellar 3 was built around 2012-2013. Following commissioning and subsequent inspection, cracking and leakage were found in the (concrete) roof. Adequate repair for recommissioning proved impossible, after which it was decided that the roof must be replaced so that drinking water cellar 3 becomes available again for the storage and supply of clean and safe drinking water.
