What are the social impact of rain water harvesting?
Answers
Rainwater harvesting reduces stormwater peak flows and total volume. This improves water quality and waterway health. It reduces the cost of infrastructure to manage stormwater, the amount of land required for wetlands and reduces the cost of flooding.
Answer:
Rainwater harvesting significantly reduces potable water use. A well designed house will save about 90,000 litres of rainwater each year, particularly in the toilet and washing machine which are year round uses. This saving at a household level changes the long term demand for water across the city, smaller treatment plants, smaller pipes, smaller pumps and less pumping, smaller dams and if desalination plants are required they need only be half the size.
Rainwater harvesting reduces stormwater peak flows and total volume. This improves water quality and waterway health. It reduces the cost of infrastructure to manage stormwater, the amount of land required for wetlands and reduces the cost of flooding. In a drought situation rainwater harvesting continues to provide water long after all runoff into dams ceases. Rainwater harvesting is therefore climate change resilient for both droughts and intense rain events.
Rainwater harvesting is a local solution that generates local jobs
