Onehunga War Memorial Pool Filtration Upgrade

The filtration for the Indoor Pools at Onehunga War Memorial Pool consists of four Pressure DE Filters. During backwashing the filters dumped water into a sump inside the plant room which was unable to cope with the capacity of water.

Watershed designed a system that connected the dump valves of all the filters into a main drain line which was piped a distance of 20m into a 12,000lt discharge tank outside the facility.
