Installing pumping equipment into existing structures can be an ideal way of creating a pump station on some sites, particularly where the structure is being created as part of a basement slab or where lead times or other consideration may demand it. 


Below are the six steps required to make sure your installation is completed safely and is Fit for Purpose and Built to Last.


Before we begin our works the chamber must be completely ready and safe for us to begin. Some points to take into consideration are as follows (list no exhaustive):-

  1. There must be good access around the pump station.

  2. Heavy items must be placed near to the pump station.

  3. Cover slab must be installed.

  4. Rising main is installed straight and level.

  5. Rising main protrudes well into the pump station.

  6. Rising main has been pressure tested.

  6. Chamber is free from debris, rubble and water.

  7. Barriers are in place to protect workers from falls.

  8. Duct(s) and Vent Pipe(s) have been installed.

Ask our team for more details.


Once we've been satisfied that the site is ready for us to start our works we will begin.  During the first visit we will install all the mechanical pipework and valves, upper guide rail holders, guide rails and auto couplings.  We may also connect onto the rising main with a flexible fitting.  In order to do this it is important that the rising main enters well into the pump chamber and is installed straight and level.  The control may also be installed at this stage ready to receive power. 


Once we have completed our first visit, the next stage is for the power to be installed.  As all internal works have been completed it is now suitable to install the manhole cover and frame to make the area safe. 


No further confined space entries will need to be made at this point.

We will advise approximate power supplies for the electrical teams to install the correct cabling requirements.


Once the power has been installed and the manhole cover is in place we can install the pump mechanically and electrically.  The pumps are typically lowered from above the chamber and automatically connect onto the coupling at the bottom.  This means that in an emergency situations they can be easily removed without getting into a full chamber of water.  If cable containment is required this is to be by others.  As pumps and level equipment are supplied with 10m of cable, please advise beforehand if it will not be sufficient.  Extra costs may be incurred if this is not the case.


Once the pumps have been installed, the concrete benching can be installed by others to avoid "dead zones" in the pump station which would allow solid matter to build up causing potential blocking issues in the future.  It is also suggested to remove any inlet bungs at this point unless it will cause any potential flooding or other issues.


Once all the above stages have been satisfactory completed, we are now ready to finish the installation and get it working.  At this point at least 1,000mm of water will need to installed within the chamber to wet test the pumps.  It is important that all rubble and debris is completely cleared before the pumps are put into permanent operation.

All electrical tests are now completed and a comprehensive commissioning certificate will be given over to the client for handover.  We are also able to attend a site handover which may incur additional cost.


You're all ready to go!
