All changes of the system components shall be documented by the designer -gym-thw fbaA4-AmIlt-drawing #4—Peak design flow is_360�.p.d.,Recommended daily flow should not exceed_288_g.p.d. or premature failure may occur. #5—Backfill sewage disposal system immediately after final inspection process,cover soils should be loamy sand or better. Seed final cover with grass or shallow rooting ground cover. #6—Keep all maintenance access lids and ports accessible to ground surface. #7—Installer should rake the finished grade smooth and slope it to divert all surface water runoff away from tack and drainfield areas. #8—Setbacks from house foundation to drainfields and reserve areas are 10',septic tanks 5' and transport lines 2'unless otherwise stated within the design. #9—Driveways and puking areas must stay 5' from drainfield areas.

Owners will receive details of this in the designer manual with the final approval of the application #17—Adhere to all designer notes located on design layout page. #18—If development exceeds 10,000 square feet of impervious surface an engineered drainage plan may need to be submitted. Options are available to reduce square footage requirements,such as wagon wheel driveways,contact DCD for further details. Owners are responsible for any fee for redesigns or revisions that may be needed after BSA submittal not due to designer error. #19—Low flow water fixtures are recommended within the home to help lower the hydraulic load to the system. #20—Watertight components are a must for all onsite sewage systems. Installers are required to ensure all components are watertight,extreme care should be used during backfilling of these components to prevent settling and or water intrusion issues. If leaking components are not fixed in a timely manner,the designers warranty may be void. #21 —Installation of this design must meet all Health Department regulations and all adopted policies by the Health Department that may apply.

It is the property owners responsibility to show the designer all plumbing stub outs and all gay and black water discharge points. A plumber may be needed on old homes to ensure that all stub out locations are connected to the newproposedsewagedisposat systems-An inside-pump-basin may be needed in some cases where plumbing is located in basements and elevations for a gravity discharge cannot be maintained. #25—Do not use low profile chambers or the system will be red tagged. All lateral lines must be a minimum of 6'offthe infiltrative surface. Lateral ends must be secured at the cleanout and must be in the center of the port. #26—Gravel trenches are recommended,but Arc 36"chambers are allowed.
