9. Why Solar? “The District is in the environmental business. We are always looking for ways to conserve our natural resources and our ratepayers’ sewer use fees. This project is just another step in the use of alternative energy which allows us to do both,” Leonard Battaglia, WCWD Board President.

10. Why Solar? “Our solar installation will cover about five acres over an existing storm water holding pond,” he says. “This design gives us dual use of the site without compromising either function. We’ll get a substantial reduction in our dollar outlay for electricity and eliminate about 1 million pounds of greenhouse gases. That’s a win-win for everyone.” E.J. Shalaby, General Manager
