This is less than the .42 required by Municipal Code for a four bedroom home. A total of 660 gallons of static storage has been added to the water system to increase water availability to the household. The storage includes 2- 330 gallon Norwesco vertical storage tanks. The tanks are NSF certified and all components of the water system including the storage tanks comply with the latest adopted edition of the Uniform Plumbing Code. The storage tanks are plumbed in line with from the well and will be filled directly by the well. Water flows directly from the static storage through a Goulds transfer pumkp to the standard pressure tank which maintains the working pressure in the water system. No water hauling is anticipated. The tanks are clearly marked "Potable Water". Sincerely, as, Michael E. Anderson, RE Attachments DC* P"M ��er.*r.. -M MANS Standard 61 -Det Mng Wetsr System Components .

We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. The subdivision is currently undeveloped and all lots surrounding this lot are vacant. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. No existing wells or septic systems are closer than 100' from the proposed septic system. Drainage arrows 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 holes placed on the lot in the area of the absorption trench and alternate site indicated silty gravel (GM) material with some sand. The percolation rate of the soil was determined to be 2.5 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. Bedrock was found at 8' below the surface. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. A lift station/pump vault will be placed in the house to pump septic effluent to the septic tank. We are proposing to place a new 1,500 -gallon Septic tank and 2-44' long by 5' wide by 1' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 1' below the surface and the total depth will be 2' to provide a minimum of 6' separation from bedrock. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. A flow diverter valve will be placed to insure even flow to each trench. Lot 4, Roseberry Highlands Subdivision September 11, 2015 Page Two The ground surface on the lot in the area of the absorption trench slopes to the southwest at approximately 10-20%. The new trench will be constructed parallel with the contours of the slope as much as possible 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' from 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. Si�ncerely, ' Q Michael E. Anderson, P.E.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 03/18/24 pOx X132 X54 -SA.1\ ..Lia "560 . a - 4co a o� --5130 -320 x 1, Aw N�,, 0 Well Water advisory Certificate of On -Site Systems Approval # OSC241067 Subdivision: Roseberry Highlands, Block: , Lot: 4 This well's productivity was determined to be .18 gallons per minute.
