In partnership with The Pump House, Allcast Precast has designed a concrete pump station for the industrial and commercial market catering for high flow stormwater and sewerage solutions. Our pump well chambers have been certified to a depth of 9 meters and are built to handle high demands, large volumes and offer life span requirements.

The base and bottom chamber are poured as one complete casting, with tapered internal walls from 150mm-190mm and a 300mm thick base. Each unit is custom made to suit the required depth and pipe penetrations making an easy installation.
