Historically, wastewater treatment started as risk reduction for human health and welfare, migrated to environmental risk reduction, and has now matured into resource recovery and revenue generation. Technology and common practices are in place to treat water as a sustainable resource; we simply can no longer afford to use it once and "throw it in the ocean" nor can we afford the liability of not treating water to our best abilities to protect human health and the environment. Specifics, metrics, and detailed examples, not generalizations and platitudes, about recovery of the "water" from wastewater will be covered. It comes down to dollars and cents, a little math, and common sense.
Water / Stormwater Management
Health, Safety and Welfare
•Discuss how to manage the design of facilities to reduce environmental, personal, and public health risk from insufficiently treated potable and reuse water supplies.
•Compare and contrast the water quality specifics, operational reliability, environmental safeguards, and public safety risks for recycle and recovery of wastewater as a secondary water supply and alternative potable water supply.
•Calculate the reduced costs and decreased environmental risks of proper wastewater treatment.
•Identify different design and operational strategies claiming to improve safety, reduce public health or environmental risks, or reduce costs.
