Eco-greywater
The system
 ECOplus standard unit
This saves flushing good clean water down the toilet, resulting in considerable water savings. It also reduces the amount of water in the septic tank and reduces surges of water into the tank which can wash partially treated efluent into the leach field, compromising its performance. Reduced hydraulic loading and mixing of layers in the septic tank results in better performance and can miraculously improve a smelly, boggy leach field.
The system produces two secondary advantages:
- Excess filtered greywater produced by the system can be used to water the garden, instead of being disposed of to the gully trap.
- Where low water pressure is present the shower will not lose the majority of its cold or hot water when the toilet is flushed.
Operation
Grey water from the washing machine, bath and shower are collected in a holding tank placed below ground level (may be buried or free standing). The water is piped to the holding tank and when full the excess water bypasses the tanks and flows into the gully trap in the normal manner.
An aeration device and a flow filter seperate the majority of soaps and lint from the water before it enters the holding tanks.
Excess soaps are directed into the gully trap and solids are held in the filter until cleaned out. To a large extent the filter is self-cleaning, diverting solids to the gully trap. The water in the end holding tank is then piped to the toilet system by a 12 volt electric pump which turns on when the toilet is flushed. A valve allows the toilet to return to the mains water supply if required. Eg when the filter requires cleaning or excess use of the toilet is required (such as a large number of visitors).

ECOplus® Standard Unit - For In Ground Installation
|
Click to view
|
ECOplus® standard unit suitable for installation into the ground. Used to recycle the bath, shower and washing machine water for flushing one toilet. Price does not include installation. Must be dug at least halfway into the ground.
Additional toilets at the same level require extra float switches and cistern fittings.
Where the toilet cisterns are at different levels they require a separate pumping system for each level. Example: a two story house requires two pumping systems, but only if there are toilets on both levels. Two pumps may also be needed for toilets on the same level if the cisterns are at different heights – check with us. Note: does not include additional toilet fittings, which should be ordered separately.
Additional prices apply for additional toilets.
