Pumps for sewage, wastewater or surface water drainage Skip to main content


At ASL Limited, when we talk about a pump we are generally referring to submersible pumps that fulfil the following roles:

  • A sewage pump assists the flow of wastewater from your septic tank or treatment plant on to the discharge point. For example drainage field or surface water;
  • A submersible sewage pump that pushes private sewage from your home to the public foul sewer;
  • A basement pump that removes flood water from your home; or
  • A rainwater pump that discharges the collected surface water from your property.

There are many different types and brand of pump for different purposes. ASL Limited can source a wide range of different branded pumps which makes it easy to provide a ‘like for like’ replacement, should yours need replacing. We carry out pump installation, repair, replacement, maintenance and servicing.

Our teams are fully trained and qualified professionals who are locally available to you. As a family-run business, we are always happy to help and give you some advice when appropriate – so you only have to ask. Why not give us a call and chat with our friendly office staff.

You can find more information on the installation and maintenance of pumping stations on our pumping stations page.

More detail on Pumps:

Some kinds of pump have more than one purpose and others are specifically designed for one task. The following table might help you understand a little more about which one you might need.

Kind of pump

Purpose of the pump

Vortex (solids handling)

Surface or wastewater.
This kind of pump can handle both.

Macerator (grinder / chopper)

This kind of pump would be unnecessary for surface water that has little to macerate.


Surface water only.
This kind of pump would likely get clogged if used for wastewater.
