Frequently asked questions

On this page you can read useful advice relating to private pumping station adoption process:

In July 2011 the Department for Environment, Food and Rural Affairs (DEFRA) passed the Private Sewerage transfer regulations: this was a two part process;

  1. Sewerage companies would become responsible for private sewers/drains from 1 October 2011
  2. Sewerage companies will become responsible for private pumping stations from 1 October 2016, which meet the eligibility criteria.

For pumping stations that do not meet the eligibility criteria, DEFRA have been consulting as to whether a specific set of regulations should be created.

All newly built private pumping stations therefore, would comply with and thus would be adopted by the relevant sewerage company as soon as they come into service, but this is currently only a future possibility.

The other option available, should your station be ineligible for adoption in October 2016, is to apply under Section 102 of the Water Industry Act to have your station adopted.

In line with the Water Industry Act, stations may need to be modified to meet the requirements before Thames Water will adopt it. This process requires an application fee.

If the pumping station meets the following criteria, then we will now be responsible for it:

  • Been in service prior to 1 July 2011
  • Connected to the main sewerage network (either foul or surface water)
  • And, either serve more than one property, or, sit outside of the curtilage (similar to boundary) of the property it serves

If you think your pumping station meets the criteria, please register the station.

If your pumping station does not meet the criteria, please contact our Developer Services team.


If your pumping station does not meet the criteria, please contact us to discuss other adoption routes that could be available to you.

We will not reimburse any maintenance or repair costs incurred prior to the date of eligibility confirmation.

We will cover all maintenance and repair costs for the pumping station from the date we confirm it is eligible, as per the DEFRA guidance.

There is no charge to transfer the station. Once we confirm the pumping station is eligible for adoption, we’ll be responsible for maintenance, repair and servicing of the station.

We are now responsible for maintaining and repairing all eligible stations, so you will no longer need a servicing contract. It is your responsibility to end the contract with your Servicing Company.

If you are concerned there is an issue with the pumping station or the beacon is flashing, please call us on 0800 009 3979, lines are open 24 hours a day. If you have the pumping station unique code (also known as a FLOC) to hand, this will make it easier for the team to identify the station. 

We are responsible for servicing the station and responding to emergencies.

We are responsible for the electricity costs associated with the pumping station from the date eligibility is confirmed.

As the supply set up is different for each station, we need your help to get the correct payment arrangements in place. If you have any queries, please contact 0800 009 3979 to discuss this further.

No. We are now responsible for any costs associated with the station as well as any improvements or maintenance work that may be needed. 

Yes. The rising mains also transferred to us with the eligible pumping stations they are connected to. 

If a rising main crosses public land and is serving a pumping station not eligible for transfer, the station and rising main on private land remains as private but the section of the rising main on third party land will now be our responsibility. 



There may be a kiosk, usually green or grey, containing electrical equipment along with a large manhole cover near to your property or in your street; this could be a pumping station. 

If you are unsure, please get in touch as it may be a pumping station we have adopted. You can contact our team on; 0800 009 3979. Lines are open Monday to Friday, from 9am to 5pm. 




Yes. If you have these documents please send them to us. If you haven’t already, please complete our online form and one of our team will be in contact to collect all the relevant information about your station.

We will agree any access on to private property with you before we visit the station for the first time. 

We are now responsible for the station which includes the pump, wet well and kiosk. We are not responsible for any compound or building; however every case is different so we will talk to you about your particular set up.

We will try to make minimal changes to the look of the station; in some circumstances however we will need to carry out work which may result in changes to the stations appearance.
