Installation guidelines

This guide is an illustration of installation guidelines which should be followed for proper installation of the Delta Dual 800
Groundwater Packaged Pumping Stations, including housing. It is important to note these instructions are for guidance only
and it is the installer's responsibility to satisfy themselves that the installation procedure is in accordance with the prevailing
ground conditions and good build practice, to eliminate any potential damage to the pump station chamber either during
or after installation. The installer should also satisfy themselves that the system can be installed in conjunction with these
guidelines, prior to work commencing.
Please read these instructions in full before beginning the installation. If you are unsure on any point then contact Delta
Membranes on 01992 523 523 between 8am and 5pm, Monday to Friday or by email at info@deltamembranes.com before
proceeding.

Pump station location

The Delta Dual 800 Groundwater Packaged Pumping Stations require routine maintenance. It is important that careful
consideration is taken to position the chamber in a location which will allow for permanent access.
4.3

Installation within a reinforced concrete sump

A structural and waterproofing engineer must be consulted when designing the waterproof
reinforced concrete sump and backfill to ensure that it can withstand the anticipated pressures,
and that they are not transferred onto the chamber.
The chamber is manufactured from tank‑grade polyethylene and is extremely robust. However, as with all pre‑formed chamber
they are susceptible to floatation and hydrostatic pressures exerted in high water table conditions.
To ensure these forces are not transferred onto the chamber, the chamber must be installed within a waterproof reinforced
concrete (RC) sump.
Furthermore, when constructing the waterproof reinforced concrete sump, adequate space must be made for connections to
the chamber e.g. inlets, discharge, cable and vent ducts. Consideration must also be made to the depth and orientation of all
connections to ensure that they line up with the chamber.
