South East Water has completed the construction of the new £50 million state-of-the-art water treatment works on the site of the old Aylesford Newsprint.
The project will see 20 million litres of fresh drinking water treated per day for the Ashford and Maidstone area.
From the M20 you can see the large, grey building that houses the equipment that carries out the filtration and disinfection processes as well as doubling as an office space for staff on site.
Boreholes have been drilled at several key points around the site, either side of the motorway. These supply the treatment works with the raw water to process and turn into safe, wholesome drinking water before it is pumped to our customers’ properties.
A large concrete tank has also been constructed on site. This is for the final element of the treatment process, where we hold the treated drinking water for a short period in a contact tank to ensure that it is ready to be pumped out.
The tank has been designed to provide resilience and contingency measures for the treatment process and was leak-tested before being brought into supply
We are pleased that Butler Water Treatment Works is now supplying water to the Kent area and we will be posting more content across our platforms for more information.

FAQs
When Aylesford Newsprint was in operation it had its own water storage tank and sourced water from a number of onsite and offsite boreholes.
