Water Harvesting Systems

Alternative water supply systems typically incorporate a water harvesting system such as a roofwater or stormwater harvesting system. These systems are well suited to industrial precincts with large impervious areas providing a high conversion of rainfall to runoff.

Water harvesting systems have common infrastructure relating to water diversion, storage, treatment and distribution. Planning of these systems also has common components to consider:

Establishing suitable end uses for the available water source.

Assessing the volume and quality of water needed to supply the end uses.

Identifying preferred catchments to harvest the water.
Understanding the infrastructure needed for diversion, storage, treatment and distribution and developing options for that infrastructure.
Determining a preferred infrastructure option using technical and economic analysis to balance capacity, water savings and costs and optimising through design.

Roofwater Harvesting

Roofwater harvesting typically involves the diversion of roof downpipes in to above ground storage tanks where the roofwater is filtered and disinfected for use in non-potable applications such as toilet flushing and landscape irrigation. More

Stormwater Harvesting

Stormwater harvesting typically involves the diversion of stormwater from a drainage system to a storage and treatment facility where it is enhanced through a multi-stage treatment process for use in high water using applications such as cooling towers. More
