A pumping station is an intermediate collecting chamber for wastewater or surface water that needs to be pumped to another location.

The most common reason our customers use a pumping station is to connect to the main drain if it is higher than the drains around your house.

Another reason for needing a pumping station is to pump sewage away from septic tanks or treatment plants. It is important to understand the do’s and don’ts of pumping away from or into a treatment plant or septic tank. If you are using a pumping station before a septic tank or treatment plant it is important that you understand about settlement. You can find out more about settlement and how treatment plants and septic tanks work on our ‘Treatment Plants’ or ‘Septic Tanks’ webpage.

Prior to having a pumping station installed it is essential to have a survey. We also need to ascertain what is required in your individual circumstance under relevant laws. Without a full insight to your individual circumstances you may not be able to get an accurate estimate.

Pumping main

A pumping main is a pipe that the sewage travels through when it is being pushed by the pump up to and into the inspection chamber to freefall into the main public sewer. A pumping main can cover great distance without disturbing the surface it is under by using no dig methods. Listed below are the different methods available in order for you to make an informed decision with guidance from us.

ASL Limited can use dig or no dig methods such as:

  • Directional boring for installing pumping mains without disturbing the surface (trenchless technology).
  • Chain trenching service for cutting a narrow trench leaving the soil as a powder consistency making backfilling easy and fast.
  • Excavator trenching in places where the ground is not suitable, or the distance is too short for the chain trencher.

“We use a trencher when we need to run a pumping main pipe through a field. We turn up on the day at a given time, check for gas pipes, electric cables etc. and are off. Our machine will cut through to the depth we want in no time, then we use a light machine – two or three-ton in weight – to gently pull the powdered soil to backfill, then we pick up our trencher and take it away, no fuss or bother. I would recommend this to anyone.”

Pump and Pumping Station maintenance

Servicing, replacements and repairs are essential to ensure your pumping station operates efficiently helping to prevent breakdown. When your pumping station breaks down it is likely that your drains may fill up and back up to the house. This can cause the kitchen gully outside to overflow. You may hear a gurgling noise when you pull the kitchen sink plug or flush your toilet which indicates either you have a blocked drain or your pump is not functioning. These two problems require different experts to attend – a blocked drains operative OR a pump engineer.

If your pumping station has an alarm system this can help you determine which problem needs solving and who to call. If you don’t have an alarm system on your pumping station ASL Limited can fit an alarm system for you and when we attend a call for a blocked drain but are made aware that you have a pumping station we can check this for you. The benefits of having a dedicated professional company who will stay on top of your pumping station maintenance can save you the time, worry and resulting inconvenience of calling the wrong expert with the wrong tools.

ASL has a purposeful powerful tanker that is able to suck the grit from the bottom of the pumping stations that would otherwise build up and interfere with the performance of the pumps. We also use our powerful jetter to release the fats that stick to the walls and interfere with the floats and switch mechanisms of the pump – which also gets sucked up along with the grit.
