Status of renovation Wastewater Pressure Pipeline

Waterboard Brabantse Delta is working on the renovation / renewal of the wastewater pressure pipeline (AWP) in the coming years. This pipeline runs from the Moerdijk industrial estate to the sewage treatment plant in Bath. We are tackling the AWP to ensure that sewage water in West Brabant can also be transported and purified reliably in the future.

The pressure stations at Roosendaal, Bergen op Zoom and Bath will be renovated first (improve reliability); Moerdijk will follow later. And the pipeline route between Bergen op Zoom and Bath will be doubled from the A4/A58 intersection to the Scheldt-Rhine Canal (increase discharge capacity). Finally, we want to ensure that the entire system of the wastewater pressure pipeline is/remains remotely monitorable and operable. This means that we will carry out an automation

going to make. As we enter the implementation phase, we would like to update you with this newsletter on the status of the project named AWP 2.0.

What have we been doing over the past period?

The tenders for the construction of the second pipeline between the Markiezaat junction (a4/a58) and the renovation of the pressure stations have been completed. A partner has also been chosen to carry out the process automation.

The renovation of the pressure stations is complex. In order to complete this job, GMB, with partners Van der Kamp, Pentair Fairbanks Nijhuis, Hoppenbrouwers and RHDHV, decided to carry out this project jointly; under the name PAUW.
The construction of the second pipeline will be carried out by GW Leidingtechniek. They are supported by

consulting firm Kragten. The contracts with these contractors have been signed. The process automation has been awarded to Croon Wolter and Dros. During construction, temporary pumping units will remain in place at the locations of the pressure stations to ensure that wastewater discharge continues during the work.

Automation

Simultaneously with the renovation, we want to ensure that the entire system of the wastewater pressure pipeline is remotely trackable and operable. In this way, we will gain more insight into the operation of the AWP. With an improved monitoring system, the AWP and the feeder pumping stations can be better monitored and maintenance optimally planned. For example, a pipe can be cleaned when it is observed to have a certain degree of fouling. Not too early, in other words, and not too late. This keeps system performance in order.

The wastewater pressure pipeline between the Moerdijk discharge station and the Hoeven site has been cleaned. This section consists of two pipelines: AWP 1 and AWP 2. AWP 1 in particular was heavily polluted.

The cleaning allows both pipelines to be fully utilized for wastewater transport. The renovation of Moerdijk pressure station is still being put out to tender. This will be continued in the coming years so that Moerdijk pressure station can be carried out immediately after Bath (2022 - 2023).

Result

By addressing the AWP, we are ensuring that wastewater in West Brabant can continue to be transported and treated reliably in the future.

Both the renovation of the pressure stations and the construction of the second pipeline will ensure that the system will soon be future-proof and in order for at least the next 30 years.

Festival Watery

Together with Brabants Landschap, water board Brabantse Delta organized 'Festival Waterrijk' on Sunday, October 21 in Bergen op Zoom at two locations: activity center Kraaijenberg and the press station of the water board. Activities were organized at both locations.

On the water board grounds, a sewer system was set up above ground where children could drive through it themselves with a sewer inspection cart. The press station hosted well-attended tours.

Many visitors were particularly interested in the rebuilding plans for the pressure station. In addition to increasing the capacity of the pumps, the building and its surroundings will be redesigned. We welcomed about 750 to 1,000 visitors to the festival.
