Operator ingenuity pays off at Illinois wastewater treatment plant

When the treatment plant in New Lenox, Ill., faced an expansion, operators saw that it was not as simple as expected. Adding three primary clarifiers increased capacity from 0.75 to 1.5 mgd.

See how their ingenuity paid off and what you could learn from their experience.

Water purification demonstration project boosts recycled water initiative

The City of San Diego, with its Water Purification Demonstration Project, is one step closer to using purified water for reservoir augmentation.

The Rahway Valley (N.J.) Sewerage Authority has boosted its plant tour program. “The best way for us to get the word out about the positive things we do for the environment is through the children,” says Jim Meehan, executive director. The kids then go home and tell their parents how much effort it takes to clean water and why the resource is precious. Tours target kids in seventh grade through high school.
