5-1-7: CONSTRUCTION AND USE OF SYSTEMS:

   A.   Failure Of Systems, Backup:

      1.   New On Site System Design: All newly installed individual on site sewage systems shall be designed and installed so that in case of subsurface sewage disposal system failure, a second subsurface sewage disposal system can be installed in a manner which will allow installation of an alternating valve and the continued use of the first subsurface sewage disposal system after rejuvenation, if the first subsurface sewage disposal system can be reused.

      2.   Failure Of Existing On Site System: When, and if, any existing individual on site sewage disposal system fails, the health authority must approve the design and installation of the replacement subsurface sewage disposal system and an alternating dual subsurface sewage disposal system must be established once the subsurface sewage disposal system has recovered sufficiently to provide adequate treatment, if it can recover.

   B.   Municipal Sewer System Variance: When a municipal sewer system is to be installed within one year, the health authority may issue a variance on the size of the individual on site sewage disposal system.

   C.   Interim On Site System/Dry Lines: The installation of an interim on site sewage disposal system in areas where dry line sewers will also be established shall require complete dry line installation to the property lines by the contractor to eliminate road, sidewalk and/or other structural removal when a municipal sewer system becomes available.

   D.   New Septic Tank Specifications: All new septic tank installations in Ada County shall have a marker pipe that shall consist of a section of four inch (4") ABS or PVC pipe that extends from a fitting in the lid of the manhole to the ground surface. (Ord. 111-1-83, 10-12-1983)
