Waterflow is the leader in onsite wastewater innovation and best practice.

Secondary Treatment System

1600L per day

Waterflow is the proud manufacturer of the Naturalflow wastewater systems. These are the leading vermiculture system in New Zealand. Providing passive breakdown and treatment of waste, the NaturalFlow systems have a completely power-free treatment process. These systems operate quietly and don’t require ongoing septic pump outs.
Made from roto-moulded plastic modules, the system is light and easily installed with lighter machinery. Making it great for those sites with challenging terrain.
By utilising aerobic bacteria throughout the treatment process, we have made it possible to have a passive and odourless system.

The NF11000 system is a 3 module combination, capable of treating a total daily flow volume of 1600 litres to ‘Secondary’ treatment level. It can discharge via LPED or PCDI – surface or subsurface laid, ETS bed, soakage bed, conventional trenches, mounds, sand trenches and arches

Commonly used for 3 – 8 bedroom houses, sleep-outs, baches, recreational and transportable dwellings, farm accommodation or rural commercial facilities with up to 40 day staff, schools, marae, camp grounds, holiday homes, motels, golf clubs, café’s, stables or other animal facilities…
