    Brief

    The first part of the sewer replacement has already been completed. The municipality has a strong ambition to make the neighborhoods climate-adaptive and greener. The combination of urban development in this area and preparing the underground for the energy transition makes this project unique. The physical construction of the heat network will not be included in the work for phases 1 and 2; this is expected to start in 2025. The main tasks include: - Replacing approximately 3,200 meters of sewer (combined system) with a separated system (DWA + DT); - Redesigning approximately 30,000 square meters of public space; - Digging water channels; - Greening the public space; - Installing walkways, bridges, and retaining walls. Project Area: The project area is located in Leiden South-West, bordered by Staringkade, Telderskade, Boshuizerkade, and Hoflaan, covering the residential streets in this area. See the selection guide for more details.
