Managing landscapes using recycled water

This paper discusses the important factors to consider and management techniques to accommodate use of recycled water. [UMN]

"Use of secondary- or tertiary-treated recycled water for landscape irrigation is increasing. The quality of recycled water is generally poorer than potable water. In the context of landscape irrigation, water quality refers to the presence and concentration of total salts (TDS, ECw), specific ions (Cl, Na, B), bicarbonate, pH, trace elements, and nutrients (N, P, K). Guidelines for interpreting water quality are provided. Evaluation of sites for irrigation with recycled water must consider plant salt tolerance, soil texture, chemical characteristics, and drainage, as well as irrigation method and frequency. Lists of tree species tolerance to salt and boron are provided. Potential problems to plants and soils can be minimized with specific management techniques." [Abstract]
