AGENDA ITEM SUMMARY March 15, 2012 TO: River Board FROM: Carla Ostberg, Pitkin County Environmental Health Department SUBJECT: Financial Assistance for Onsite Wastewater Treatment System (OWTS) Replacement Introduction: This summary is intended to generally inform the Board of the effect of failing OWTSs, commonly referred to as septic systems, on the environment and public health, as well as to alert the Board of a current situation having the potential to negatively impact the environment and public health in the Capitol Creek drainage. "Wastewater", also known as sewage, is defined in the Pitkin County OWTS Regulation as a combination of liquid wastes that may include chemicals, household wastes, human excreta, animal excreta, other animal or vegetable matter in suspension or solution, and that is discharged from any building, dwelling, or other establishment. Pitkin County has approximately 3000 parcels that fall outside of a sanitation district, relying on OWTSs to treat their wastewater. Malfunctioning OWTSs contribute to non - point source pollution and negatively impact water quality. Non -point source pollution differs from point source pollution in that the pollution is not coming from a single source, such as a factory. Non -point source pollution comes from the cumulative effect of day to day activities including road maintenance, fertilizer application, and use of OWTSs. The impact of non -point source pollution is often difficult quantify in the same way pollution from a point source can be identified and measured. In the last several years, the Pitkin County Environmental Health Department has seen an increase in OWTS permits issued to address failures. Aging systems, improper maintenance, and increased water use are all factors that are likely contributing to OWTS failure rates in Pitkin County. However, failing OWTSs are not just a problem in Pitkin County. Nationwide, contamination from septic systems and sewage overflows is an issue of great concern. American Rivers, an organization founded in 1973 to protect and restore the nation's rivers and streams, posts the following information regarding the implications of sewage contamination on the environment and public health: "Sewage pollutes our waters with pathogens, excess nutrients, heavy metals, and other toxins. It kills aquatic life and creates algal blooms that can suffocate fisheries. Even worse, sewage carries pathogens that can end up in our drinking water supplies and swimming areas. These disease -causing microorganisms cause diarrhea, vomiting, respiratory, and other infections, hepatitis, dysentery, and other diseases. Common illnesses caused by swimming in and drinking untreated or partially treated sewage include March 15, 2012 C 0 Request for OWTS funding gastroenteritis, but sewage is also linked to long term, chronic illnesses such as cancer, heart disease, and arthritis." (w)Aw.americanrivers.org) In February, I was contacted by the owners of a residence located at 703o E. Sopris Creek Road. The OWTS serving the residence on the property, permitted and installed in 1999, had failed and wastewater was coming to the ground surface. Capitol Creek is located approximately 125 feet downhill from the lowest portion of the failed absorption area. There are also several private drinking water wells in close proximity to the OWTS. The cause of the failure is difficult to pinpoint as the system is relatively new, water use is conservative, and maintenance of the system has been consistent; however, the receiving soils are clay, meaning that it takes longer for any water or wastewater introduced to the soil to absorb. The owners immediately addressed the problem by replacing the failed system with appropriate technologies for the site and soil conditions. I understand that maintaining and improving water quality and quantity within the Roaring Fork watershed is one of several objectives of the Healthy Rivers and Streams fund was established to attain. I believe that providing loans to homeowners needing to replace and repair malfunctioning OWTSs aligns well with that objective. There are a number of other states and counties that have established loan programs specifically to address OWTS repair and replacement. A loan program of this type would benefit Pitkin County residents while facilitating greater protection of our water resources. Project Cost: $25,000 Requested Board Action: Approve funding a loan, based on the County Attorney's approval of the loan agreement, for the property owners of 703o E. Sopris Creek Road to offset the cost of replacing the OWTS serving this residence.

Details for MircoFast to follow: Assume equipment from Valley Pre Cast. Sub Surface Conditions and Testina: A Subsurface soil investigation was performed by SE. A profile hole was excavated to 7' deep and a shallow trench was excavated to obtain soil samples for USDA soil classification. The soil at 12" deep appears to be a blocky clay loam to silty clay loam. A hydrometer Analysis is being performed to further cla and determine the loading rate. We assume that the loading rate i 0.3 als/SF/day. . Groundwater levels are expected to be below a minimum et from the existing surface grades in the area of the proposed drip field. o evidence of groudwater was encountered in the profile pit. Soil Dispersal S,�tem Design: 7j 5 L�P_ I r �1 `{i Ct L 5V I CI C,,/ ) The assumed design hydraulic loading rate is 0.3 gal/S.F./day for the native soils 12-18 inches below the surface grades on the hillside. The conservative hydraulic loading rate of 0.3 gal/S.F./day was used to size the preliminary drip field system. The system provides for intermittent pressure dosing treated effluent, in shallow driplines, across the field. The dispersal area is sized based on the calculated quantity of treated effluent utilizing the standard Geoflow dripline sizing criteria utilizing the design loading rate. The dripline dispersal system is proceeded by an ATU (Micro Fast) secondary treatment unit that will treat the septic tank effluent prior to discharge to the field. The treated effluent will be pressure dosed in small quantities across the field at frequent intervals through individual dripline laterals. The small amount of treated effluent will infiltrate into the natural soils over an average 12" diameter radius around the individual dripline emitters. The area required for dispersal field utilizing the loading rate for the native soils is approximately 3000 S.F. assuming the standard 2' on center emitter spacing and the minimum 2" separation between dripline laterals. The calculated total length of dripline is 1500 L.F. We assume that the field will consist of 12 laterals each 125 feet long or 16 laterals each 194 feet long. The supply and return line manifold pipes will be in the some trnch on the east side. Each pair of laterals will be looped on the west side with each loop connected with a tee fitting to an air bleed manifold.
