Co. , MN This On-Site Sewage Treatment System is Designed for a Type l, three bedroom home and discharge from an iron filter adding an additional bedroom totaling four bedroom home. Designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local �ordinances . This site has an existing failing system�with effluent backing up into the basement. The existing system is in a high water table & strong clay soil & is also located less than 75 ' from the wetland to the south . The system will need to be abandoned & replac�d with a new one. The soils on this site are SCS soils mappcd - KkB - Kilkenny loarn. A seasonally high water table �aas located at 28" , 30" & 36" , (mottled soil ) . Due to the seasonally high water table, a Pressurized Mound System will need to be installed. Tne bottom oF the rock bed must be located at least 3 ' above the seasonally high water table. The soils at a depth of 12" have a percolation rate a�veraging 4 . 1 min/inch. Due to the clay soil , the liner is not nee��ed. A pumping chamber will need to be installed to lift the effluent to the treatment area. 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 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 . (Mercury floats are a good m�thod) . CONT' D . Mrs . Tearse � 1520 Fox Street � Orono (21 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 h�ve no probl�m in treating septic effluent effectively. Recommend to pump the septic tank every year if there is only 1 tank & every 2 years if there are 2 tanks . _ � . teven B.

Tank was last pumped 6-�3'L�`i ). Make sure septic tanks are pumped through manhole and not throu�h white inspection pipes. This allows for the proper cleaninQ. Keep water softner and iron filter discharge out of septic system to prolong life of drainfield. Ask pumper to test alarm float to verify alarm is still working in your house. The alarm warns owner that septage is about to backup into basement. 7 Inspection risers missing-tanks could not be inspected. Inspection risers(4"dia.pipe)must be installed in each tank. If tanks have not been pumped out within the last three years,they should be pumped out now.

A summary of the inspection is below. Sepdc Tank Condition 1. Pumpout needed within one year.(Last Pumpout 6/22/96.) 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 tl�ree 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 31,2010. Enclosed is a list of state licensed septic contractors who work in Orono on a regular basis. Also enclosed is a fact sheet elplaining how a septic system functions properly. Finally, an as-built drawing is enclosed that shows the approYimate location of the septic system. If y�ou have any questions regarding this report, please contact me at the City Offices at 249-4600.
