4No. rotating half bridge scrapers supplied for two 16.5M primary settlement tanks (PSTs) at Haddington Wastewater Treatment Works by Colloide Engineering Systems. Colloide contracted for the detailed Mechanical & Electrical design, supply and delivery of the bridge scrapers. ESD acted as the main contractors and carried out the civil engineering works.

Haddington Sewage Works is situated to the north of Amisfield Walled Garden. Colloide’s bridge scraper installations are part of a £3.8 million upgrade and maintenance project by Scottish Water and their alliance partners ESD. The work, which includes upgrades to the treatment process, will ensure that the works can continue to operate effectively now and in the future.
