Great Valley is a town in Cattaraugus County, New York. The town has a total area of approximately 50 square miles. Based upon the 2010 census, the population is 1,974, with a Median Household Income of $48,490 with 14% of people living below the poverty level. The town is centrally located in the county, northeast of the City of Salamanca and the Hamlet of Kill Buck is east of Salamanca.
The Cattaraugus County Health Department (CCHD) administers a private septic system program throughout the county and is very familiar with the chronic operational problems and documented sewage discharges that present a public health hazard within the Kill Buck neighborhood.
The primary problems with existing septic systems are the poor drainage characteristics of the native soils, a high-water table, and the small lot sizes, which do not provide enough area for a properly-sized septic system meeting the New York State (NYS) design standards. CCHD sanitarians generally complete a dye test of home plumbing as part of required property transfer inspections. In the case of one Great Valley home with a failing septic system, the dye was discovered discharging into a local stream which means that sewage is seeping directly into that stream. The CCHD also tested the water coming from the storm sewer along nearby NYS Route 417 and confirmed the presence of high levels of fecal coliform bacteria which typically comes from sewage. This documented that some septic systems are illegally tied into storm drains and directly contribute to the contamination of Great Valley Creek and the Allegheny River. The Allegheny River and downstream Reservoir are widely used for boating and swimming recreation throughout the summer months and for community water supplies. This poses another direct route for human exposure and illness.
Since most of the onsite systems are undersized and 50 or more years old, the CCHD expects more systems to fail each year. The lack of a public sewer system is preventing any future economic growth and poses significant health and safety risks.
The engineering study funded by CDBG would evaluate the existing condition of the on-site septic systems in the hamlet from available records, and evaluate several alternatives for improving the collection, treatment and disposal of the hamlet’s wastewater. Preliminary indications are that the construction of a collection system to then convey wastewater to the City of Salamanca for treatment may be the best course of action at this time.
The Town of Great Valley has given full endorsement for the project by authorizing the preparation of the planning grant application by RCAP Solutions. The Town has authorized 5% matching funds for the proposed study. Town officials are committed to meeting with engineering consultants on a regular basis as the plan is developed and will hold public meetings to discuss plan recommendations with relevant stakeholders. With continued assistance from RCAP Solutions, officials will work on securing the necessary funding for the infrastructure improvements recommended by the engineering report once it is completed.
