A summary of the inspection is below. Septic Tank Condition 1. Pumpout needed within one year.(Last Pumpout unknown.) The septic system is non-compliant due to a lack of a three foot separation distance between the bottom of the drainfield to the seasonally high watertable. The three foot requirement is a State Code,not a City Code. A soil boring was conducted to determine the depth of the seasonally watertable. The septic system must be replaced no later than December 31,2006. Enclosed is a list of state licensed septic contractors who work in Orono on a regular basis. Also enclosed is a fact sheet explaining how a septic system functions properly. Finally, an as-built drawing is enclosed that shows the approximate location of the septic system. If you have any questions regarding this report, please contact me at the City Offices at 249-4600. :Re ectfull , s Pence On-Site Systems Manager Enclosures In the event this inspection report is used to satisfy the requirements for a mortgage or other transfer of property,be advised that this report does no guarantee or certify the existing system will continue to function properly,but is merely an opinion of the adequacy of the system under current conditions based on the available information. This report must be kept on the premises with the system location and pumping records.

Co., MN in full compliance with all applicable aeptio&W=W%cc& Requirements including items not specifically Salad iN*ii w*1M KEEP THIS PLAN UT ON UrRAT ALL TMU This site has an existing on-site sewage treatment system which is hydraulically overloaded and very near surface discharging. If the system surface discharges, this is classified as an imminent health hazard which must be repaired or disconnected within 10 months. This on-site sewage treatment system is designed for a Type 1, three bedroom home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are a clay loam. The seasonally saturated soils were located at (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the rock must be located at least 3' above the saturated soils. Approval will be needed to be 10' from the north & east property lines. The soils at a depth of 12" have a percolation rate of 8.8 mpi. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump failure. 1 The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. The supply line will cross underground utilities. The supply line will need to be insulated through the driveway. The existing tanks will be abandoned, pumped and removed due to being in the area of a possible addition to the home. All neighboring wells are located greater than 100' away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid & the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tanks. Recommend Iron filters be diverted out of the system. Recommend to divert the water softner also if the iron filter is diverted. Garbage disposals are not recommended, due to adding more solids & fine solids passing through to the system. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower cleaners used every shower & chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend to pump & clean your tanks through the manhole by a certified pumper every 2 years. Check with your pumper to set up a schedule. Steven B.
