01What is being requested

The assignment concerns the realization of a wastewater transport pipeline (ø315mm) from the current AWTG Leimuiden to the AWZI Nieuwe Wetering, including crossing the Rijksweg A4 and HSL.

The existing AWZI Leimuiden will eventually be relocated, as a capacity expansion also took place during the renovation of AWZI Nieuwe Wetering a few years prior, allowing the latter to take over the treatment operations of AWZI Leimuiden. To make this possible, the current AWTG's must be renovated or renewed, and a new AWTL (ø315mm) must ensure the transport of wastewater to Nieuwe Wetering.

What will be done with the existing pipes at the location?
The current AWTG's must be renovated or renewed. Additionally, an existing ø400 pipe (from AWTG Oude Wetering) located at the Natuurbelevingstuin De Bult will be partially renewed.
