Modular Inlet Works System for Ōpōtiki WWTP

In the last eighteen months Hydroflux has delivered over twenty (20) inlet works packages to sewage treatment plants located all over New Zealand, in order to remove debris that would otherwise accumulate in the downstream treatment process, reducing process efficiency and comprising performance.

The packaged inlet works are delivered as pre-engineered systems that are simple to install, include automatic bypass arrangements and reduce civil works requirements.

This latest project for Ōpōtiki WWTP included a custom designed inlet feed well and isolation penstocks, in addition to the pre-fabricated stainless steel inlet works chamber.
