Pumping systems from concept to maintenance

Peter Stam works as a project consultant at REMONDIS Smart Infra Westland in Wateringen. With eight branches, REMONDIS is a nationwide installation company in the field of quantitative water and infrastructure management. Most of its clients are contractors and governments from municipalities through water boards and provinces to the Department of Public Works.

Stam: "In addition to the waste and recycling branch, REMONDIS Netherlands has the Smart Infra division where I work and what we conveniently call the 'pump branch'. Think of sewage pumping stations so complete with pumping and control installation, automating polder pumping stations and weirs. And pumping installations where highways are sunken, so also at overpasses, aqueducts and in tunnels to pump away the rainwater that flows in."

REMONDIS Smart Infra engineers, supplies and installs complete pumping systems from small to large, but also provides maintenance, service, inspection and renovation after installation.

Pumping plants

Stam: "For the Rijkswaterstaat A9 Badhoevedorp-Holendrecht project, VeenIX is our client. We came into contact with them because of our knowledge and experience with pumping systems and the associated controls for tunnels. A construction consortium finds everything under one roof with us. From the very beginning, we support our clients with advice and engineering. Then, following our advice and assistance, the contractor pours the concrete structure with pump pit. Then we supply and install the pump system."

With regard to the A9 project, REMONDIS Smart Infra has been engaged in three places. The first project was completed: the installation of a Temporary Pumping Station. Stam: "There was an original pumping station with five pumps directly behind the noise barrier of the old A9. We replaced it with a Temporary Pumping Station. This was initially planned for three to four years, but it will eventually be more."

REMONDIS Smart Infra makes a clear difference in dirty (sewer) and clean (rain) water. The second project is with three dry mounted pumps the Keizer Karelweg sewerage pumping station, which will eventually be transferred to the municipality of Amstelveen. Tribe:
"The pressure lines from this will be on the roof of the land tunnel. The drained dirty water goes towards the wastewater treatment plant. From the start of this project, the Municipality of Amstelveen has been directly involved with its own program of requirements (PVE)."

Insightful process

The third project is the final pumping station to replace the Temporary Pumping Station. 3D engineering is being used extensively in the development. Stam: "That not only has added value for REMONDIS, it also makes the entire process more transparent for the client. That comes in handy during engineering about the position of pumps and piping and, for example, the locations of cable ducts. We also find this advantage during execution. We have been actively using 3D engineering in our projects for years."

Stam cites as a strength of REMONDIS Smart Infra that the client can turn to one party from concept to installation and long-term maintenance. The locations are monitored via a telemetry system. Based on the reports thus obtained, remote intervention or a decision to go to the location can be taken. Each project has its own project manager who is the central point of contact for the client.
