RECYCLED WASTEWATER FOR PARKLAND PLANT IRRIGATION AND SUSTAINABILITY MEASURES

water is one of the main water resources with substantial contribution to increase the security of future water supplies. Scientific and technical studies are required to maximize this contribution through developing water recycling opportunities and reuses particularly for green space irrigation to provide environmentally, socially and economically sustainable environments. The use of municipal recycled water for green space plants is a valuable attempt to use the easily available water resources but it requires a monitoring system to mitigate the possible inverse impacts on the soil, plants and water systems. Variables such as climate, irrigation methods and frequency, plant species and soil can have a profound effect on the sensitivities of plants to salts and toxicity. Soil drainage, irrigation application rate, water quality, rainfall characteristics and plant canopy shade can influence the long-term effects of salinity, and toxic effects of chemical compounds on the vegetation health. It is, therefore, important to have information specific to each individual plant species, as well as information on all the above-variables, specific to each locality, in order to properly plan and manage water requirements of specific landscapes. In this paper the main potential inverse impacts of reuse of recycled water for irrigation is discussed and Adelaide parklands as a case study is briefly
