01What is being requested
The contract concerns the realisation of a new rainwater and foul water sewer system in the Noorderkwartier Oost of Leiden, including a drain to regulate the groundwater level and stabilize the settlement-sensitive clay soil. Total works include approximately 2,000 m of foul water sewer, 3,000 m of rainwater sewer, 400 m of relining, 2,000 m of drainage, and 30,000 m² of redesigning the living environment with greener street design. The contract falls under a non-public procedure and focuses on an integrated approach to water drainage, groundwater management, and urban renewal.
The rainwater sewer will be disconnected from the foul water sewer so that rainwater can be discharged more effectively during heavy rainfall. Additionally, a drain will be installed to maintain the groundwater level at a constant level and protect homes against groundwater levels that are too high or too low. This drain will also ensure that the settlement-sensitive clay soil in this area will subside less. The streets will be designed to be much more “green”.
