Pressure Sewer

Why choose Pressure Sewer over gravity?

Wastewater treatment and infrastructure is an essential part of any community. However, traditional gravity sewer systems are not the most appropriate or cost-effective solution in difficult ground conditions. Fall requirements to maintain adequate flow by gravity may require deep excavations in hilly or flat terrain, adding to the risk of hitting rock or groundwater as well as the addition of expensive pump stations. If only there was a better way…

There is. Ecoflow is New Zealand’s leading supplier of Pressure Sewer Systems. And with the use of the global market leading grinder pump (E/One), Pressure Sewer Systems provide a far more reliable, resilient and controllable transfer of wastewater from the household to the treatment plant than conventional methods.

Pressure Sewer Systems are becoming increasingly popular amongst engineering consultants, council asset managers, and developers thanks to the advantages and cost savings they offer over traditional gravity systems.

Pressurised systems use specially designed grinder pumps that reduce any solids into a slurry, which is then pumped into the network. Each household has a grinder pump which does little work, on average only 20 minutes/day of pumping. This is how we get such great longevity out of the wearing parts. Serviceability of the grinder pump network is easy, all grinder pumps are identical, interchangeable and have a design life of 25 years. Because transport of sewage is done under pressure, the pipe network can follow the contour of the land at shallow depth.

Moreover, upgrading to smart controllers which communicate via a cellular network to an online portal give councils complete control of their pressure sewer networks. This allows councils to monitor and control the network, reduce peak flows, hold back pumping during storm events and offer a higher level of service to the homeowner.
