A summary of the inspection is below. Septic Tank Condition 1. Pumpout needed within one year.(Last Pumpout????.) 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.

In addition , lour(4) soil borings were drill d with a 2" i.d.x 3 1/4" o.d. Hand auger to c k 11or the position of the ground water table and to i the underlying soil types. Locati of tests and boring's are shown on the site plan. The percolation tests were performed in accordance with the provisions of"Minnesota Pollution Control Agency Rules and Standards Chapter 7030". The percolation test holes were drilled to a depth of 24 inches with a 5" i.d. x 6" o.d. auger. Two inches of pea gravel were placed in the bottom of each hole to prevent scoring. Water was then added to the test holes and replenished as necessary, maintaining a saturation, each hole was refilled to a 20-inch head of water over the bottom, and the percolation tests commenced. PERCOLATION TEST RESULTS Results of percolation tests at holes P-1, P-2, P-3 and P-4 are shown as observed. Percolation rates in minutes per inch are: P-1 P-2 P-3 P-4 30 mpi 34 mpi 42 mpi 40 mpi Primary Site Ave. 32 mpi Secondary Site Average 41 mpi 4 DESIGN REQUIREMENTS Considering the soil data and minimum design requirements of the Septic System Ordinance, our proposal is as follows: Construct a Standard Septic System based on a 3 bedroom Type I home average of 450 gallons per day. Proposed Design Size= 450 gpd X 2.0 =900 square feet of drain field 2- 1000 gallon tanks 1- 1000 gallon pump chamber CONSTRUCTION PROCEDURE FOR A SELVAGE TREATMENT DRAIN FIELD Tanks must be installed level. There must be inspection pipes installed vertical to the tank above both baffles and in the center manhole which shall not be more than 12" below the final grade. The drain pipes between the house and the tanks shall be schedule 40 pvc. Tile septage must be lifted to the drain field via a 2" manifold ending in the first drop box. The pump must have at least 17 feet of head pressure and a gallon per minute rating of at least 10 but no more than 45. The pump must be made of cast iron or brass and be submerged continuously. The pumping cycle shall be at least 110 gallons but no more than 140 gallons per cycle. Trench construction must be shallow and follow the contour of the slope. Note: Contractor must shoot elevations to obtain the contour. Bottom of drain field trenches must be level from drop box to trench end. Install SB-2 gravelless tile or a comparable and approved product. Backfill with care taken to support the underside of the tile. Trench depth below existing grade will vary from 12 to 14 inches. See site sketch for elevations. The plastic limit of the soil must be acceptable in order to work soil. A vertical inspection pipe of at least 2" in diameter shall be installed in each end of every trench. The inspection pipe shall be installed with 3/8" or larger perforations spaced vertically no more than six inches apart. At least 2 of the perforations must be placed in the tile and be capped flush or above finished grade. A water meter can be installed to insure the actual water use does not exceed the designed capacity. MAINTENANCE Pumping of Septic Tanks. The owner of any individual sewage treatment system must properly inspected, and if necessary, clean the septic tank or tanks at least once every year in order to prevent the sludge from reaching any point closer than 12" from the bottom of the outlet baffle or the scum from reaching a point closer than 3-inches above the bottom of the outlet baffle. This is required by City Codes. DrainaKe and final landscaping All surface waters must be kept away from the drain field area. A drainage plan should be completed to ensure that surface run-off from roof and parking surfaces are drained away from the system. NOTE : If a chlorinated Hot tub is installed in the house this must be daylighted and not plumed into the septic system. Chlorine does kill bacteria in the septic tanks. Also, any sump pumps, pools, ground water, water softeners, or any other non-plumbed water devices must not be run into the septic system. To do so will void any and all warranties. GENERAL The contents of this site evaluation and design report are to be applied to the property listed, reprints for other applications only with the permission of Don's Backhoe& Excavating Inc.. The soil conditions have been established at the test hole locations only. There may be variations in soil stratigraphy between and around the boring's, and interpolation and extrapolation of the results is not warranted. All requirements of this design sliall be followed in order for the system to perform up to the designed capabilities.

This must be done at least once every three years. Sludge, or septage, includes the settled materials at the bottom of the tank, the floating scum materials at the top of the tank and the liquid in the tank at the time of cletuiing. The septic tank should be cleaned whenever the top of(lie sludge layer is closer than 12 inches to the bottom of the outlet baffle or whenever the bottom of the scum - layer is closer than 3 inches to the bottom of the outlet baffle. Both conditions likely will not occur at the same time in a septic tank, but " either condition requires tank cleaning. PENCIL MARKS „n MANHOLE INLET .•°':.. . ..

Push the measuring device through the scurn layer into the liquid layer. If the stick is carefully moved down and up, resistance on the"foot" should locate the bottom of the scurn layer. Equipment is also commercially avail- able to measure scum and sludge accumulations. Mark the stick at a convenient reference point when you feel the bottom of the scum layer. With the same stick, locate the bottom of the outlet baffle. Determine the distance between the bottom of the scum layer and the bottom of the outlet baffle by measuring the dis- tance between the marks on the stick. 12" EARTH COVER GRASS COVER HOUSE � = SUMP PUMP SEPTIC TANK DROP 130'^q- J-1 OXgJ-j OUTLET SEWER MIN.

(When consolidated impermeable bedrock is present, the vertical separation distance necessary is 7 feet.) When aerobic conditions exist in the clean sand, the long-term acceptance rate will be 1.2 gallons per day per square foot. If the depth to the restricting layer is inadequate or the rock bed is too wide, anaerobic conditions may exist and cause a much slower acceptance rate. The possibility of anaerobic conditions occurring in the clean sand and subsequent hydraulic failure is a major design consideration when mounds larger than those required for single-family residences are required.

PROCEDURE A total of four(4) soil percolation tests were performed on May 24, 1994 in areas to the north-northwest of the existing dwelling. In addition , four(4) soil boring's were drilled with a 2" i.d.x 3 1/4" c,.d. Hand auger to check !dor the position of the ground water talo-lie art to ►lie►iti y t{ic uii,,:i g�Oii iyNc�. ivGdtiOii vi �c��� and boring's are shown on the site plan. The percolation tests were performed in accordance with the provisions of"Minnesota Peilution Control Agency Rules and Standards Chapter 7080". The percolation test holes were drilled to a depth of 24 inches with a .5" i.d. x 6" o.d. anger. Two inches of pea gravel were placed in the bottom of each hole to prevent scoring. Water was then added to the test holes and replenished as necessary, maintaining a saturation, each hole was refilled tv u 2v-iii�h h,:au Ci Vvut(;r v'v'�r the bottom, and the percolation tests commenced. PERCOLATION TEST RESULTS Results of percolation tests at holes P-1, P-2, P-3 and P-4 are shown as observed.
