Delivery of renewed septic tanks (VSTs)
Hoogheemraadschap Hollands Noorderkwartier (HHNK) wishes to replace 647 existing IBAs (Infrastructuur Buitengewone Afval) in the Noorderkwartier with renewed septic tanks (VSTs). The IBAs have been under the management of HHNK since 2005 and are managed jointly with 21 municipalities. The assignment is an open, public delivery without a CPV code. The VSTs must comply with Dutch regulations for wastewater treatment, be sustainable, and be suitable for local soil and water conditions. Installation, connection to the existing network, and aftercare (maintenance and monitoring) fall within the scope. The tender requires close cooperation with the involved municipalities, clear delivery and completion plans, and a total solution that guarantees the continuity of wastewater management. The assignment is technically challenging, but the scale is manageable and the market is reasonably developed, resulting in an estimated medium complexity.

The assignment is technically challenging, but the scale is manageable and the market is reasonably developed, resulting in an estimated medium complexity.
In the Noorderkwartier management area (North Holland above the North Sea Canal), twenty-one municipalities jointly own 647 IBAs. (For completeness: the municipality of Amsterdam has 60 IBAs and Texel has 8, and 5 will not be replaced by a VST; these fall outside the scope of the assignment.) HHNK has managed and maintained these IBAs since their installation around 2005 based on agreements with the involved municipalities. The IBAs must now be replaced by VSTs.
