Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.
Sustainability, One Project at a Time
As a utility in one of the fastest-growing regions of Puget Sound, the LOTT (cities of Lacey, Olympia, and Tumwater; and Thurston County) Alliance has taken an innovative approach to sustainability: managing growth one chunk at a time.
Survival Without Bypass
Is your plant designed to treat only twice its average flow but receives flows in excess of four times the average? Are storm events in the region high intensity and short duration? Do site
constraints or availability of funds preclude construction of equalization basins? Are the secondary clarifiers shallow or overloaded? Is your plant facing increasingly strict effluent nutrient permit limits? Is it located in a cold climate?
If you answered yes to any of these questions, this article is for you.
Water Reuse: What's on the Horizon?
Recent advances in water reuse technology have reduced operating costs, improved efficiencies, and significantly enhanced the quality of treated effluent — enabling municipalities to consider reuse projects that previously would have been economically and technically infeasible.
These improvements, coupled with growing concerns about maintaining adequate water supplies in drier regions of the world, have grown the market for membranes and other water reuse technologies.
