What is groundwater replenishment?
What is groundwater replenishment? It’s an innovative concept where treated wastewater is further treated to drinking water standards and recharged into our groundwater supplies. The water can then be stored in our underground aquifers, which store and naturally filter the water until we need it.
What is the meaning of water recycle?
Water recycling technologies include the processes and equipments involved in the activities of treatment, storage and distribution of used water. The term ‘water recycling’ basically refers to wastewater treatment which can produce the reuse-water for other beneficial purposes.
How many groundwater treatment plants supply water to Perth?
113 wastewater treatment plants
We operate 113 wastewater treatment plants across the state.
What are two ways that groundwater can be replenished?
Aquifers may be artificially recharged in two main ways: One way is to spread water over the land in pits, furrows, or ditches, or to erect small dams in stream channels to detain and deflect surface runoff, thereby allowing it to infiltrate to the aquifer; the other way is to construct recharge wells and inject water …
Which river has highest replenishable groundwater resource?
The correct answer is Ganga. The Ganga and the Brahamaputra basins, have about 46 per cent of the total replenishable groundwater resources.
How does water recycling work?
Water reuse (also commonly known as water recycling or water reclamation) reclaims water from a variety of sources then treats and reuses it for beneficial purposes such as agriculture and irrigation, potable water supplies, groundwater replenishment, industrial processes, and environmental restoration.
Why is water recycling important?
All water is recycled and reused as a part of natural water processes such as the hydrologic cycle. Recycling wastewater can extend water supplies, improve water quality, reduce discharge and disposal costs of wastewater, and save energy.
Why does Western Australia use groundwater?
In many parts of Australia, native fauna and flora rely solely on groundwater for their survival. Groundwater also contributes water directly to rivers and lakes as baseflow, often maintaining surface water bodies in times of drought. In the arid zone, groundwater sustains important natural and cultural values.
What are some of the major environmental issues around the use of groundwater in Perth?
If garden bores draw water faster than groundwater is recharged by rainfall, groundwater levels can drop. This has a serious impact on Perth’s lakes, wetlands, parks and bushland. Falling groundwater levels can also lead to water quality problems, including acid sulphate soils and saltwater intrusion.
Can you replenish groundwater?
For example, groundwater can be artificially recharged by redirecting water across the land surface through canals, infiltration basins, or ponds; adding irrigation furrows or sprinkler systems; or simply injecting water directly into the subsurface through injection wells.
