DEP RULE PROPOSAL SEEKS TO CONSERVE WATER BY
MORE RECLAMATION OF TREATED WASTEWATER
(08/16) TRENTON - The Department of Environmental Protection has proposed new rules to encourage more reclamation of treated wastewater for a variety of uses such as irrigation of lawns, parks, and athletic fields, as well as in industrial processes, Commissioner Lisa P. Jackson announced today.
“Once again, New Jersey is at the forefront of using innovative thinking to tackle environmental challenges,” Commissioner Jackson said. “This proposal sets the bar for treatment of reclaimed wastewater very high and encourages wastewater facilities in areas of the state with stressed water supplies to examine the feasibility of implementing strategies to reclaim wastewater.”
These initiatives are included as amendments made to the proposed re-adoption of the New Jersey Pollutant Discharge Elimination System rule.
The amendments set high treatment standards for reclaimed water. They require wastewater facilities that discharge into coastal water bodies or those that are located in Critical Water Supply Areas to study the feasibility of using reclaimed water as a condition of NJPDES permits. These are areas that stand to benefit most from wastewater reclamation because of stressed water supplies.
“By going through this study process, some wastewater facilities may discover that reclaiming wastewater makes a lot of sense economically and benefits their local environments,” Commissioner Jackson said.
“The implementation of any beneficial reuse program will not necessarily enable wastewater facilities to expand sewer service areas or increase treatment capacity,” said Nancy Wittenberg, DEP’s assistant commissioner for environmental regulation. “At the same time, wastewater reclamation can help water utilities that face allocation constraints because of stressed supplies meet growing demand for water.”
The DEP will exempt facilities from the feasibility study requirement in cases where reductions in discharges of treated wastewater would have adverse effects on water resources. Wastewater treatment facilities that produce an average of less than 100,000 gallons per day will also be exempt.
Reclaimed wastewater has the potential to be used widely to irrigate golf courses, parks, athletic fields, highway medians, sod farms, pasture lands and certain crops, such as those that are peeled or processed before consumption.
Industries can also use reclaimed water to cool equipment, to wash parts and to operate equipment.
Some wastewater treatment systems already participate in DEP-approved wastewater reclamation projects that include irrigation of golf courses, landscaping and highway medians; street and sewer cleaning; dust control; firefighting; and as non-contact industrial cooling water.
