" PROJECT DESCRIPTION: THE EXISPMG WASTEWATER SYSTEM CONSISTS OF A 1,000 GAL. CONCRETE SEPTIC TANK DISCHARGING TO AN APPARENT LEACH FIELD. GIVEN ITS �
40 30 20 10 0 40 80 160 PROBABLE AGE (40+ YEARS) AND CURRENT OPERAT70NSAL ISSUE' IT IS PROPSED TO INSTALL A REPLACEMENT SYSTEM. IT IS PROPOSED TO HAVE THE BUILDING SEWER FLOW TO
(IN FEET) THE SEPTIC TANK BY GRAVITY, ONCE ALL SOLIDS ARE SETTLED, THE EFFLUENT TO FLOW BY GRAVITY TO A DISTRIBUTION BOX, THEN DISTRIBUTE AMONGST THE LATERALS IN THE J s ti
PROPOSED SHALLOW ABSORPTION TRENCHES. ANY REMNANTS OF THE EXISTING SYSTEM WILL BE REMOVED AND REPLACED WITH SUITABLE SAND BASED SO/L(PERC RATE 6-7
1 INCH = 40 FT. MINUTES/INCH).
WATER SUPPLY., WELL LOCATED GREATER THAN 10OFT OF PROPOSED FIELD.
PROJECTED FLOWRATE.• BASED ON A FIVE (5) BEDROOM COUNT AND NYS DOH STANDARDS FOR POST 1991 WATER SAVING FIXTURES ® 110 GALLONS PER DAY PER BEDROOM,
THE AVERAGE DAILY FLOW (ADF) IS 550 GALLONS. SHOULD HOUSEHOLD FIXTURES NOT BE OF THE 'LOW FLOW' TYPE MANUFACTURED SINCE 1991 THEN THE FIXTURES SHALL BE d w
REPLACED AS NEEDED. THIS FLOWRATE DOES NOT INCLUDE THE USE OF A GARBAGE GRINDER (NOR IS ONE RECOMMENDED) OR A HOT TUB/SPA. ADDIT70NAL FLOWRATE MUST
BE INCLUDED IN THE DESIGN SHOULD EITHER OF THESE COMPONENTS BE PART OF THE HOUSE DESIGN. _
SEPTIC TANK: DESIGN CAPACITY— 1,500 GALLON (MINIMUM). A 1,500 GALLON SEPTIC TANK IS PROPOSED FOR THE EXISTING RESIDENCES. f
ABSORPTION FIELD SYSTEM: THE ABSORPTION SYSTEM IS DESIGNED AS A DISPERSAL SYSTEM WITH SIX (6) LATERALS AT 55 LF, TOTAL ABSORPTION AREA EQUAL TO 640 SF
