All communities need a supply of clean, safe water. Some communities, and the utilities that serve them, have the luxury of tapping into additional water sources when their primary supplies face quality or quantity issues. However, because traditional water sources, such as surface water and groundwater, are highly dependent on location, many utilities don’t have easy access to contingency supplies. As increased pressures from drought, extreme weather, and shifting populations make backup supplies more critical, many utilities are looking beyond traditional sources to diversify their supplies. Many communities are also grappling with political and institutional issues, like local control of water supplies, driving the need to identify new, local options to avoid the need to import water.
All of these circumstances make water reuse an attractive option. Potable reuse purifies water from wastewater treatment plants through advanced treatment methods to meet drinking water standards, while non-potable reuse recycles municipal wastewater and water from impaired sources for activities that don’t involve human consumption, such as landscape and crop irrigation, industrial processes, and other uses.
Exploring Potable Reuse to Diversify Water Supplies
This video offers insights from water utility leaders on why direct potable reuse (DPR) may be a crucial future water supply option. It also discusses WRF research that is developing recommendations and guidance for the appropriate use of blending as part of DPR and helping water utilities and regulators evaluate the safety of existing or potential DPR facilities. This video was filmed at the Santa Clara Valley Water Department’s Silicon Valley Advanced Water Purification Center.
