CLEARMASTERS
Pump stations in towers and mixed-use buildings
New towers and mixed-use buildings rely on pump stations and sumps. We service them on a planned schedule, test every pump and alarm, and report to the managing agent or facilities team.
Learn moreStratford has been rebuilt since the 2012 Olympics. The Queen Elizabeth Olympic Park, East Village, the International Quarter and the towers around the station have brought tens of thousands of new homes, offices, shops and restaurants. Almost every new building has plant rooms, pump stations or sumps that need planned maintenance.
Restaurants and food courts in the shopping centres and around the park need grease traps emptied regularly. Older streets in Stratford, Forest Gate and Maryland are Victorian terraces with shared drains. The Lea and the Bow Back Rivers run through the area.
We’re SafeContractor, Achilles UVDB and RISQS approved, our crews work in east London most days, and we answer the phone 24 hours a day.
