Two community-level advantages of water harvesting are that it reduces water bills and decreases the overall demand for water, potentially leading to lower costs for water services. Additionally, water harvesting can help prevent flooding by managing stormwater runoff and improving groundwater levels, which can reduce the risk of flooding.
Elaboration:
Reduced Water Bills:
By harvesting rainwater, communities can reduce their reliance on municipal water supplies, leading to lower water bills.
Decreased Water Demand:
Water harvesting helps to meet some of a community’s water needs, reducing the overall demand for water from traditional sources.
Flood Prevention:
Rainwater harvesting can help to manage stormwater runoff, reducing the risk of flooding in urban areas.
Improved Groundwater Levels:
By capturing and storing rainwater, communities can help recharge groundwater aquifers, potentially increasing water availability during dry periods.
