The filter station in conjunction with the lift station is the primary stage of the greywater recycling system. It is vital that greywater is filtered for the removal of particles of solid matter and the various personal hygiene products used while showering or bathing.

The holding tank is the secondary stage of the greywater recycling system. The importance of the holding tank is its storage capacity relative to the number of people it will serve within a building. The holding tank must collect and store enough greywater to supply the building’s toilet flushing requirements.
3. Disinfection
The disinfection of the greywater stored in the holding tank is performed by the monitoring of the volumes of incoming greywater by the systems electronic water management controller on the pump station. The greywater is driven from the holding tank by a dedicated chlorination pump through the chlorination housing (containing calcium hypochlorite) to the lift station (a separate tank) through the filter station and then onto the holding tank.
4. Greywater Distribution

On demand (toilet flushing) greywater is taken from the holding tank and pumped under pressure automatically by an inverter controlled multistage centrifugal pump distributing it to the building’s toilets. The inverter control maintains constant operating pressure at a selected pressure setting. The pump cycles up when greywater is consumed and automatically cycles down as water usage decreases.
Water Management Control
The pump station features the Greyter Commercial Controller (GCC-100), an electronic water management controller, which is responsible for the monitoring and control of the complete system, including greywater tank levels, system pressure and temperature, actuated valve control, disinfecting circuit, greywater diversion and water usage monitoring.
Fresh Water By-Pass
In the event of low levels of greywater in the holding tank, the GCC-100 controller will automatically activate the actuated valve on the pump station which will allow freshwater to supply the building’s toilets. Once the level of greywater within the holding tank increases, the GCC-100 controller will automatically activate the actuated valve on the pump station. This will again allow greywater to supply the building’s toilets.
Water monitoring
The volumes of grey and fresh water used to service toilets is monitored by the GCC-100 controller and the information can be used to calculate how much potable water has been saved by recycling greywater.
