Design and Build Award for Arlington WTW

We are delighted to have been appointed as design and build contractors for the upgrade of Arlington Water Treatment Works (WTW). Colloide working on behalf of Enisca Browne in wider collaboration with South East Water are designing and upgrading the existing 5no. sand filters at Arlington WTW in East Sussex.

The Water Treatment Works at Arlington were developed nearly half a century ago, see below Alan Mitchell who helped manage the installation of specialist water equipment at Arlington before it was commissioned in 1971. Alan recently got the chance to see the fruits of his labour still in action at a recent open day held by South East Water.

Arlington WTW nearly 50 years on requires updating to stay on top of standards and to ensure that water produced continues to be of the highest quality. Colloide’s solution included removing the existing media filters and supplying and installing new media filters, aswell as replacing the associated flooring and railing works around the filter cells. This update will continue to see Arlington produce the equivalent of 1.5 baths of water every second of the day.

Scope of work

In order to upgrade Arlington WTW, we will remove the existing media on the existing 5no. sand filters and supply and install new media.

Other works included

  • Providing and installing new flooring ‘D shaped’ sections for 5no. filters, fixed to walls of the existing 5 filter cells. Finished floor level of D section to match that of existing concrete. 
  • Providing handrail and kicker plate around 5 filters (8 sides and 5 ends).
