Malpas Wastewater Treatment Works, Cheshire

One of the main things we do at Welsh Water is aim to provide you with a reliable wastewater service which will take away the wastewater you flush away or wash down the sink. To make sure we continue to do this, we need to carry out improvements to our Malpas Wastewater Treatment Works.

To facilitate the work at Malpas Wastewater Treatment Works, we need to acquire a nearby small parcel of unregistered land to house the new equipment, and we want to give you the opportunity to have a look at the information and share your feedback with us.

What are we doing?

Over the next few months, we will be carrying out improvements to the treatment works as well as adding a new process to the site to ensure we treat the water to the highest standard before it is returned to the environment. We will be carrying out the work on site in two phases:

  • The first phase will see us carry out improvements to the equipment and process within the site to treat the flows coming in.
  • The second phase of the work involves adding a new phosphorus removal process to help improve the quality of the treated water that comes from site.

This work will start over the next couple of months, and we should have everything finished by Summer 2025.

To facilitate the work at Malpas Wastewater Treatment Works, we need to acquire a small parcel of unregistered land to the north of the existing site to house the new equipment.
