Replacement pressure pipeline rg. Volendam

What will happen?

In the municipality of Edam-Volendam and a small section in the municipality of Waterland, the existing sewage pressure pipeline from sewage pumping station Volendam to the sewage treatment plant (rwzi) Katwoude will be replaced and its discharge capacity increased.

Inspections have determined that the existing sewage pressure pipeline has reached the end of its technical lifespan. In consultation with the municipality of Edam-Volendam, it was decided to abandon the route of the current pressurized pipeline and find a new route, as much as possible in municipal land. The existing pipeline now lies mostly in residents' gardens and partly even under trees. A new route limits the inconvenience to the surrounding area.

The new discharge line from the Booster Edam and the future discharge line Baanstee Noord will pierce the new discharge line Volendam-rwzi Katwoude. The existing connections will be transferred to the new discharge line. It concerns the discharge line of the recreation center Slobbeland, the discharge line of cheese farm Alida Hoeve and the discharge line of Hotel Volendam (Motel Katwoude). In the future, the new Lange Weeren development plan will also be connected.

In the image below, the existing pressure pipeline is shown in yellow. The new discharge line is shown in light brown. Here is also an image of the new discharge line in Google Earth.

Method of construction

Most of the new pressure pipeline will be laid using horizontal directional drilling (HDD). HDD makes it possible to lay a pipeline underground from two points over a longer distance. The deep location means that any obstacles can be passed without hindrance and inconvenience to the surrounding area is limited. Thanks to this implementation method, the Water Board only has to set up work areas in a few places. Within these work areas, the equipment of the HDD installation will be set up.

Planning

The project will be implemented in 2 phases. In 2023 we will have completed the construction of sewer pumping station Volendam up to the water storage facility Zeddeweg. In 2024 the section from the water storage facility Zeddeweg to the Katwoude rwzi will follow.

Other developments

We are now investigating whether we can use sewage heat. Recovering heat from sewage water through which we can heat houses. HHNK is doing this research together with the municipality of Edam-Volendam.
