New generator makes water treatment more environmentally sustainable at East Lothian site

The installation of a new hydro power generator has led to Scottish Water’s Castle Moffat treatment works becoming the organisation’s most environmentally friendly site.

The water treatment works, just south of Garvald in East Lothian, abstracts water from Whiteadder Reservoir and now generates more energy than it uses. It is the only Scottish Water asset where  pumped water is used to power a site and it generates 750,000 kWh/annum, enough to power 2,416 homes.

The new hydro power generator and control panel were upgraded in a £200,000 investment in May 2019.
