Basement Pump Installation & Commissioning

As basement pump installation and commissioning specialists of Delta Membrane Systems equipment, we carry out the mechanical and electrical installation of sump pumps, internal pipework and associated accessories like high level alarms and control panels.

At first, we will either offer an on-site survey to ensure your site is ready for installation, or allow you to do this via an online survey form and a virtual call. The choice is yours. Once this is complete and the site is ready, we will proceed with the basement pump installation and commissioning according to the manufacturer’s guidelines, where on completion you will receive a detailed report, certificate of completion and O&M manuals.

Using us for installation and commissioning allows us to form a partnership with both you and your client and enables us to look after their pump stations for years to come. It’s personal.

Please note, site surveys are free of charge unless the installation doesn’t go ahead (charged upfront). All warranties remain with the manufacturer of the installed equipment. Commissioning is free of charge, unless unable to do at the time of installation, thereafter it becomes chargeable. Quotation and prices are all subject to site survey. Our prices do not include any work to the external pipework, civil work or installation of the sump itself. Our prices include the mechanical and electrical installation of sump pumps, internal pipework and associated accessories like high level alarms and control panels. Before the installation, the sump/s should be in the ground, clean and ready for final installation (discharge pipework and cable duct run with drawcord). All cable ducts should be accessible. Chamber covers should be removable. If we attend site and the area or pump station is inaccessible, unfit for work, not ready for installation, etc. you will be liable to a cancelled call charge.
