Subject: T15N R1 W SEC8 Lot 113
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of the Lot 113, at T15N R1W SEC8 intends to construct a new four-
bedroom home on the lot. We are therefore requesting a permit be issued for the
construction of a new well and septic system to accommodate the home. The attached
Site Plan and backup documentation identify the location and configuration of the
proposed well and septic system along with the alternate site. Also identified on the
plans are the existing wells in the area and septic systems on surrounding lots. No
conflicts exist between the proposed septic system and the existing septic systems and
wells on this and adjacent lots. Drainage arrows and ground surface contours are
shown on the site plan showing the grade and direction of flow on the lot. The drainage
pattern will not be changed as a result of this project.
The test hole placed on the lot in the area of the absorption trenches and alternate site
indicates silty sand. This test hole was perked, and a second perk test was performed
about 60' away. The soils were very hard, although the percolation rate was tested at
under 10 minutes per inch. No groundwater was found during the placement of the test
hole and none was found during the monitoring period. A conservative application rate
of 0.6 gallons per day per square foot was used in the design of the absorption system.
We are proposing to place a new 1 ,250-gallon septic tank and two 50' long by 5' wide
by 4' effective depth absorption trenches to treat and dispose of the effluent generated
in the house. The elevation of the distribution line in the absorption trench will be 2.0'
below the surface and the total depth will be 6.0'. A minimum of 2" of insulation and 2'
of fill will be placed over the absorption trench and septic tank.
The ground surface on the lot in the area of the septic system slopes to the northeast at
a shallow grade. The new trench will be constructed parallel to the ground contours in
conformance with Municipal requirements. The new septic system will be constructed a
minimum of 100' from all wells and any surface water and 10' the proposed and existing
water services in the area.
If the system is constructed in accordance with our design the following statements
apply:
1. The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
3. The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
4. The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
