Step 1
H2grO – Greywater for Gardens system diverts greywater supplied from the bathroom and/or laundry to your garden where it is used to irrigate plants. When you pull the plug on greywater, it flows down through subfloor drainpipes and into the top of the H2grO unit. Your greywater then passes through a stainless steel filter screen to remove lint, hair and large particles after which it collects in a pumpwell. When the level rises in the pumpwell, a float switch activates the pump and the collected greywater is pumped into the subsurface irrigation network.
Step 2
During periods of rainfall or when the greywater quality is unsuitable for garden use, divert the greywater to sewer. Fitting an optional rain/moisture sensor to the automatic H2grO will do this automatically.
Step 3
The water flows through a stainless steel filter screen to remove large contaminants such as hair and lint. This screen is set at an angle so that these contaminants buildup, they will be flushed to sewer.
Step 4
Should power supply be interupted or the H2grO pump develop a fault, the greywater level will rise in the pumpwell, overflow a weir below the filter
screen and discharge safely to sewer.
Step 5
In the unlikely event that the council sewer becomes blocked and backs
up into the H2grO, a level sensing pressure switch mounted inside the electrical enclosure will prevent the pump operating and divert the valve to sewer. Once the sewer blockage is rectified the system will need to be cleaned before resuming normal operation.
