Oasen De Laak


Construction of a drinking water reservoir of 3850 m3. This included foundations, round prestressed concrete tank (23m diameter, 11m high) and architectural finishes.

The project

The project consisted of the construction of a prestressed concrete storage tank 23m diameter; 10m high (climb), and further:

  • Construction of foundations/capping and pipe routes;
  • Installation of new piping + integration with existing system;
  • Delivery and Assembly of internal stainless steel pipework;
  • Delivery and assembly of electrical and control/automation installations
  • Disinfection of the entire plant
  • Some prefab elements such as roofing sheets;

The work was carried out in close proximity to roads and in an operational area. Visser & Smit Bouw has therefore coordinated all the logistics and transport elements. The site layout took into account the location of the project in a protected water catchment area.
