Hi Everyone,
I wanted to see someone with more experience could offer advice in our situation. We are struggling with a remodel design because of distances (nearly 100ft) involved in the plan. Is the minimum depth for the sewer pipe below grade at 1 ft or 2ft? What is the minimum depth for the outlet of the waste piping at the edge of the house? And finally what is the minimum depth for the sewer lines outside of the building?
The City has said that they will allow a slope of 1% provided we use a 4" pipe. But because of the distance involved, I am not sure we can make it work with the existing grades.
I looked up the following code reference from the 2010 CALIFORNIA PLUMBING CODE.
Thanks in advance for any advice you may have.
"718.3 No building sewer or other drainage piping or part thereof, which is constructed of materials other than those approved for use under or within a building, shall be installed under or within two (2) feet (610 mm) of any building or structure, or part thereof, nor less than one (1) foot (305 mm) below the surface of the ground. The provisions of this subsection include structures such as porches and steps, whether covered or uncovered; breezeways; roofed porte cocheres; roofed patios; carports; covered walks; covered driveways; and similar structures or appurtenances."
