Industrial Pretreatment Program
The Water Reclamation Facility for Henrico County, Virginia is a 75 mgd regional POTW with 1800 miles of sanitary sewer ranging in size from 8 inches to 84 inches. There is always the potential for an industrial discharge that is not compatible with the biological nature of the facility, thereby causing an upset. Pollutants may also pass-through the facility to the historic James River and cause an environmental problem for the river and our neighbors along the estuary. Bio-solids are dewatered and, by separate contract, applied to farmers’ fields as a soil amendment. Whether the liquid is discharged to the James River, or, the solids are applied to a farmer’s field, it is essential that an Industrial Pretreatment Program (IPP) continuously identifies potential significant industrial users, and permits their discharges.
Industrial Waste Survey
The General Pretreatment Regulations require identification of all possible Industrial Users which might be subject to the Pretreatment Program. Although not required but once every few years, the potential is great that a discharger could be connected to the sanitary system and cause great harm to the facility, and to the river. The Henrico County Industrial Waste Survey (IWS) program continuously monitors the types of commercial or industrial customers being connected to our system. By knowing the nature of the business, we can classify the discharger into one of several two-letter Sub-Classification Codes (see below). The Customer Service Representatives are our ‘first line of defense’ in determining new customer, or new tenant, status. The CSR asks, ‘what is the nature of your business?’ and then proceeds to classify the customer.
Customers added to the billing system are reviewed monthly. If there is any question about the nature of the business, a one page survey form is sent to that customer. The response may initiate a more in-depth joint IWS/Discharge Application form.
