Install Self Contained Sewage System
Dowdens Pumping and Water Treatment have successfully supplied, installed and commissioned a 48,000L sewerage system for St Catherines Primary School in Proserpine, Queensland.
St Catherine Primary School has been increasing in its numbers over the past couple of years and therefore needed a larger scale and updated sewage system. The water table could have been an issue as it sits 1.5 m below the surface; however, the Dowdens team came up with a great solution.
Dowdens Pumping and Water Treatment, in conjunction with the project’s designers, redesigned the original project scope of 3 x 16,000L concrete tanks sitting at 3.5m deep with pour in situ concrete bases. By changing to a 48,000L Aquatec Emergency Storage Vessel, the project avoided an expensive excavation and dewatering of the tank pit where the water table sits at 1.5m below the surface.
The tank is a 1.85m diameter x 18m long fibreglass tank weighing less than 2 Tonnes. Due to the smaller tank diameter, the site excavation only needed to be 2.3m deep rather than the original 3.8m. The tank was held down by an in-house engineered concrete ballast which was poured on top of the tank.
