Can Co-Locating Utilities Solve The Water-Energy Nexus?
Try explaining to your children, as I have with mine, that turning on a light is akin to running a faucet. You’ll likely get a confused look, but this is perhaps the simplest example of the relationship between water and energy (the “nexus”). It’s only one side of the coin, however. Water and wastewater operators experience the other side, chewing through electricity (and their budgets) to treat and transport water.

Pump Station Bar Screen Saves Wastewater Utility $26,000 In Annual Labor
New Jersey’s Lower Township Municipal Utilities Authority had a problem. The utilities authority operates a 5 MGD plant, with wastewater inflow arriving through a 48-in pipe routed 23 feet below grade level. Their manual inflow pump screening setup was difficult and hazardous to clean, and its 2.5” screen spacing let entirely too much non-dispersible waste through. Their 3,000 GPM non-clog pumps were constantly clogging, and workers were repeatedly exposed to a hazardous situation.
