One trench is currently installed at 47.5 feet. The proposed design changes are as follows: • 1000 -gallon septic tank will be changed to a 1250 -gallon HDPE septic tank • We are proposing to change the length of the trenches to the following: 0 4 -bedroom home: 600 gpd 0 0.45 application rating (per the design) = 600/0.45 = 1333 ft' o Existing 47.5 -foot trench with 7 feet of effective = 665 ftZ (this trench is already installed) o Proposed second trench will be 48 feet with 7 feet of effective = 672 ftZ (they would like to install this today) o Total ftZ will be 665 + 672 = 1337 ftZ (1333 ft' required) It should be noted that the 47.5 -foot trench that is installed will be slightly undersized (667.5 ft' required for an even 50/50 split — currently has 665 ftZ).
