Do you require onsite wastewater treatment?

Autoflow wastewater treatment systems are a unique, sustainable, environmentally friendly system, especially designed to utilize natures process in the treatment of wastewater. Solid waste is converted into humus by a living eco system of decomposer organisms (compost worms, bugs, beetles etc).


A sustainable waste treatment system working for the environment. No chemicals.


Because of the aerobic process this system does not produce offensive odours.


No sucking out, no blowers to service or repair.


The system comes in Kit-Set form. Lightweight tanks are excellent for difficult sites.


The simplicity and effectiveness of this system means costs are kept to a minimum.

How Autoflow systems work

Liquid waste is passed through a series of filtration mediums before being dispersed into a planted evapotranspiration field, or soil infiltration system. Superior to a septic tank, more user-friendly than a composting toilet and lower maintenance than an aerated wastewater treatment system! (AWTS)

1. Vermicomposting & Greywater tanks: Receive black & grey wastewater flows, filter & compost solids.

2. Batch reactor with dosing siphon or pump: Treats the water.

3. EVAPO transpiration field: Reintroduces water back into the environment.

South Canterbury

A client from South Canterbury, 60km inland from Timaru in the South Island, approached us looking for a sustainable wastewater treatment system to complement the sustainable house he was building. He wanted a system that would allow his wastewater to be used as a resource: water for irrigation and compost for the garden. He also wanted a system with few moving parts because of possible winter power outages. SEE MORE
