Upgrade Septic System Permit Request
Design Narrative
This is a design narrative to issue a permit to install an upgrade septic system for this property. The system will serve an
existing four (4) bedroom house. The system will utilize an existing 1500g septic tank and a conventional gravity fed drain
field. This lot is served by a private well. The surrounding lots are undeveloped and there are no wells within 100' of the
proposed septic system.
1. Soils. PES performed one test hole on the property in the area of the proposed system on 09JUL19 and completed
seven day water monitoring on 09AUG19. Ground water was not observed to a depth of 16'. Bedrock was not
encountered in the test hole to 16.0. The percolation rate of the soils was 0.3mpi and a sieve analysis was performed
(results attached) resulting in a SP soil so no sand filter is required. Based on the results of the test hole and sieve
analysis, an application rate of 1.2 GPD/SF was used for a conventional wastewater.
2. Soil Absorption System Design.
a. See Sheet 1 of the design package.
3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field.
4. Topography: The existing topography on the lot generally slopes from west to the east. The proposed field is to be
installed in a slope of 8%-20% and there are no steep slopes in the area of the proposed system.
5. Drawing Markings: The Drawings are marked "For MoA Review Only." When written notification that the review is
complete and that there are no further comments received from MoA On -Site Department, the note will be removed and
"Issued for Construction" drawings will be issued.
The proposed installation will not affect the future development of this or the surrounding lots.
If you have any questions or concerns, please contact me at 745-8200.
Sincerely,
Steven R. Pannone, P.E.
