Stormwater recycling

Water scarcity, rapid population growth and increasing urbanization are placing increasing pressures on water supply systems, and this may be further exacerbated by climate change. Thus, water recycling presents an attractive option for augmenting water supplies. Stormwater recycling as irrigation water for public lands presents a potential solution but this water can contain pollutants that are harmful to human health if exposure, particularly for vulnerable groups such as the elderly and small children, to these pollutants occurs during the irrigation process. Stormwater reuse also faces social and economic challenges, which may be affected by a changing climate. This research will determine how stormwater recycling for irrigation can be made environmentally, socially and economically acceptable and lead to the development of guidelines and policies on stormwater reuse for irrigating public lands that are robust and resilient under a changing climate.
