1).Whenwas the WVSA constructed and how was it modified?

WVSAwas established in 1962. The company was modified such that it couldprovide the residents with clean and safe treated wastewater. TheWVSA does run an accredited Industrial Pretreatment Program, which isa central government’s compulsory policy and is endorsed by theClean Water Act (CWA). The WVSA manages a U.S. EnvironmentalProtection Agency’s (EPA) endorsed IndustrialPretreatment Program, in the capacity of an approval authority(WyomingValley Sanitary Authority 1).

2).What is the source of the sewage and from what communities does itoriginate?

WaterWVSA treats come from various sources including ground water,industries, homes, businesses, and schools located in the LuzerneCounty. The WVSA’s serviced region encompasses 35 municipalitiesthat range from Newport Township to Pittston to Harveys Lake (WyomingValley Sanitary Authority 1).

3).How does the sewage arrive at the WVSA?Thesewage water from Luzerne County arrives at WVSA through CombinedSewer Overflow (CSO). The current transportation system is similar tothe traditional overflow systems. The storm water (snow or rain fromparking lots and off streets) and wastewater (sewage and used waterthat businesses and homes release down the drains) collects in asingle that directs it to WVSA facility. This transportation pipe isknown as a Combined Sewer System. In times of heavy rains, the CSOsmay overflow, thereby releasing the excess water into either thelocal creeks or the Susquehanna River. This surplus eliminationprocess is called Combined Sewer Overflow (CSO). It offers a “safetyvalve” that protects back-ups of unpurified wastewater intobusinesses and homes, bursting of underground pipes and city streetsflooding. The Combined Sewer System in Wyoming Valley was constructedin early 1900s, as the city was rapidly developing, to provide aneconomical strategy for handling storm and wastewater. However, theCSOs are efficient and advantageous during low to moderate rainfallseasons since the drainage takes both the wastewater and storm waterto the treatment plant prior to discharging it into Susquehanna River(WyomingValley Sanitary Authority 1).

4).Describe the treatment process in detail.TheWVSA treatment process starts at “pretreatment stage”, whichinvolves an initial treatment of the nondomestic wastewater prior todischarging it into the combined sewer system (CSO) leading to themain treatment plant. All businesses releasing their wastewater intoPOTWs should pre-treat their wastewater in order to satisfyregulations set by local authorities, the state, and the EPA. Some ofthe strategies these nondomestic sewage sources use to pre-treatwater include filtration, chemical precipitation,sedimentation/flotation, and pH adjustment just to mention a few(WyomingValley Sanitary Authority 1).

SignificantIndustrial Users (SIUs) are supposed to apply for a special permitprovided by the WVSA. The organizations should also conduct regularself-monitoring inspections of their wastewater, and then takeself-monitoring reports (SMRS) to WVSA for approval. Moreover, theauthority has special professionals who conduct industrialinspections and monitoring to ensure the businesses do comply withthe set regulations (WyomingValley Sanitary Authority 1).

TheWVSA applies two unique discharge limits. One of them includes theCategorical Pretreatment Standards, which are implemented by the EPAin compliance Section 307 of the Clean Water Act. These techniquesare based on technology, and are used with certain processwastewaters from given industrial classes. The industries arewholesomely called Categorical Industrial Users (CIUs). The LocalLimits is the other discharge limit used to regulate the IUs. Locallimits aims at controlling specific capabilities and needs ofparticular POTWs (WyomingValley Sanitary Authority 1).

TheIndustrial Pretreatment Department at WVSA also manages a greaseinspection program, which aims at reducing incidences of sewer lineoverflows and blockages resulting from fats, oils, and grease (FOGs)buildup. WVSA conducts on-site investigations to monitor compliancelevel (WyomingValley Sanitary Authority 1).

TheWVSA pretreatment program also operates a hauled domestic wastewaterprogram that permits wastewater-hauling services to dispose sludgeand septage from companies from wastewater treatment facilities thatdeals with purifying domestic sewage (WyomingValley Sanitary Authority 1).

5).Where us the wastewater after treatment discharge to?

Thewastewater after treatment is often discharged into Susquehanna River(WyomingValley Sanitary Authority 1).6).What are the waste products from the treatment process and how is thewaste disposed of?

Thewaste products from the treatment process include septage and sludge.The WVSA runs hauled domestic wastewater program that licenseswastewater-hauling services in charge of disposing the waste productsfrom the wastewater treatment plants (WyomingValley Sanitary Authority 1).7). How did the facility meet the new Total Maximum Daily Limit ofNitrogen, Phosphorus and Total Dissolved levels? What was estimatedcost and how was it paid for?

TheWVSA attained the new Total Maximum Daily Limit of Nitrogen,Phosphorus, and Total Dissolved levels through constructing a naturalgas wastewater treatment facility. The approximated cost of thefacility was between $8 million and $10 million dollars. The CateStreet Equity firm financed the cost of constructing the plant(Skraptis 1)
