TOTAL: 1,338 M2

WATER/WASTEWATER SUMMARY

AREA AVAILABLE IS NOT LARGE ENOUGH TO ACCOMMODATE REQUIRED LEACH FIELD

RECOMMEND CONNECTING WASTEWATER DISCHARGE TO EXISTING MUNICIPAL COLLECTION LINE

IF WELL WILL PRODUCE AT LEAST 41 GPM, INSTALL A PRESSURIZED WATER SYSTEM USING A 7.5 HP PUMP.

IF WELL PRODUCES LESS THAN 41 GPM, INSTALL AN OPEN SYSTEM WITH A STORAGE TANK.
