ONSITE SEWER SYSTEM DESIGN DWG

The County Health Department expects drawings that they can easily read and the only way that can be accomplished is by hand drafting. Yes Auto Cad drawings just can’t provide that without over kill and costing 3 or 4 times as much.

T.E.S.C. POND ANALYSIS:

SURFACE AREA POND CALCULATIONS PER DOE

SA = Surface Area = (1.2) (Q for 10YR, Average between existing and developed)/(Velocity of Settling)

SA = (1.2) ((2.10+3.73)/2 cfs)/ (0.00096 fps)

SA = 3,644 SF (Pond settling surface Required)

SA = > 4,000 SF (Pond settling surface Provided)

SA = Surface Area = (1.2)(Q for 10YR, Average between existing and developed)/(Velocity of Settling)

SA = (1.2) ((2.15+3.52)/2 cfs)/ (0.00096 fps)

SA = 3,544 SF (Pond settling surface Required)

SA = > 4,000 SF (Pond settling surface Provided)

SA = Surface Area = (1.2)(Q for 10YR, Average between existing and developed)/(Velocity of Settling)

SA = (1.2) ((1.04+3.29)/2 cfs)/ (0.00096 fps)

SA = 2,706 SF (Pond settling surface Required)

SA = > 3,000 SF (Pond settling surface Provided)

I feel that when the local jurisdictions stand with the landowner and utilize the value of habitable growth of the land to include our future generations this economy will stabilize. So it is the government that is governed by the people that need to catch up. The landowner needs to make contact with the Civil Engineer to move forward with development.
