Why Pressure Sewer
Pressure sewers are wastewater collection systems that are easier to install and more resilient. They protect the environment and public health for years to come.
Users of pressure sewers are contributing to keeping new zealand as clean, pure, and safe as possible.
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. Gravity sewers are also prone to stormwater and groundwater infiltration that strain the systems - especially during wet weather events. This can cause sewage overflows that close swimming beaches, risk public health, and impact the environment. 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 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. Because transport of sewage is done under pressure, the pipe network can follow the contour of the land at shallow depth. 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 and interchangeable. Grinder pumps typically run to failure and service interval varies based on usage. It’s important to keep debris out of the system like wipes and fats. That will help extend the service interval. But if there is a problem, Ecoflow is here to help!
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.
