While standard tank and drainfield systems are th most common type of onsite wastewater disposal system, more advanced ystems are available that greatly increase the quality of septic tank was ewater discharge. These systems are called enhanced treatment syst ms, They include Intermittent Sand Filter systems, A TU's (Aerobic Treat¡ent Units) and Textile Filter systems. Aerobic Treatment Units consist of two types: Suspended Growth (usually single compartment) and Fixed Film ( sually multi-compartment). WHY ARE ENHANCED SYSTEMS REQUIRED? Standard tank and- drainfield systems provide good environmental protection when placed in good soil conditions with adequate spacing between systems. However, where soils are too porous or the water table is too high or spacing between systems is tight, more advanced treatment may be required. At the time of writing, approximately 250 subdivision lots have been approved in the Star Valley area, since 2002, with the provisionthat enhanced treatment be employed. 20 + systems are installed and working. WHICH SYSTEMS HAVE BEEN APPROVED SO FAR? Neighboring states have been using levels of BOD (Biological Oxygen Demand) and SS (Suspended Solids) as performance indicators for enhanced systems. Wyoming DEQ (Department of Environmental Quality) has recommended maximum levels of TKN (Total Kjedahl Nitrogen < 25 mg/ml) and Fecal Coliform bacteria reduction« 800 colonies/l00ml). The enhanced systems approved in our area, consist of either Textile Filter or Fixed Film Aerobic Treatment Units: Brand name Type of system Web site address Approx. cost AdvanTex® Textile Filter www.orencosystems.com Depending on site conditions and/or FAST ® Fixed Film ATU www.biomicrobics.com specific requirements of pennit and/or J et-Bat® Fixed Film A TU www. ietincorp.com engineering, the range is between No r wic!? \ $7,500.00 and l vi tv t..".

They have also shown significant 493 .", J. '~eduction of Fecal Coliform levels as well. Number of colonies is typically r'educed from tens of thousands down to between 1,000 - 3,000 colonies/l00ml. In order to further reduce these levels, there needs to be either good soil structure below the drainfield or a disinfection device ahead of the drainfield. Engineered requirements for enhanced systems may include a provision for ultra violet treatment where ground water separation, is less than six feet. WHA T IS THE REASON FO~ A MAINTENANCE AGREEMENT? Whenever mechanical components are added to a system, additional maintenance is required, As stated above, standard septic systems do protect the groundwater WHEN PROPERLY DESIGNED, WHEN PROPERLY INSTALLED AND IF PROPERLY MAINTAINED. Without proper maintenance, standard systems can and do fail. Enhanced systems require semi-annual inspections including annual sampling. The attached form is a contract between the property owner and Lincoln County that will be completed and filed with the County Clerk. The county commits to ongoing record keeping and enforcement with this agreement. The property òwner commits to proper ongoing operation and maintenance of the enhanced septic system. HOW MUCH WILL MAINTENANCE COSTS BE? Treatment systems that bear the NSF International Standard 40 seal of approval include the inspection and sampling costs for the first two years in the purchase price. Beginning with the third year, the property owner is responsible for the cost of ongoing semia~nualinspections including the annual sampling. Evidence of test results and proof of service contract renewal shall be made available to the Office of Planning and Development each year. It is projected to cost between $150.00 and $200.00 per year for the service contract beginning with the third year. As with standard septic systems, periodic pumping will be required. However, due to the regular inspections, a recommendation to ' , pump the tank will happen when actually required, instead of too late or too often. GOOD NEWS, BAD NEWS! The bad news is that enhanced septic systems require ongoing maintenance. The good news, for groundwater, is that enhanced septic systems require ongoing maintenance!

C. lnorder to comply with W:yoming Department of Enviromnental Quality Regulations: the Owner shall provide for the ongoing inspection, sampling and maintenance of the Treatment System. D. As the Small '\Vaste'\vater Facility delegated authority, the County also requires the Owner to agree to provide for the ongoing inspection, sampling and maintenance of the Treatment System. NO\V, THEREFORE, Owner agrees as follows: 1. Upon installation of the Treatment System and the execution of this Agreement, Owner shall provide annual evidence of ongoing Treatment System maintenance in the form of sampling results AND a copy of service contract for the following year with a provider authorized by the Treatment System's manuÍacrurer. 2. O'wner is requireò to keep the Treatment System on the Properiy iµ good operation, condition anò repair, Some repair or replacement costs may not be covered by a servIce cODtraci. Owner will be responsible to pay all costs not covered. O~Z84ZS U00495 3.
