§ 15.65.040. Use of on-site disposal systems.

A.

A person may not construct, install or use an on-site wastewater disposal system except in accordance with the provisions of this chapter or other ordinances, regulations or statutes in effect at the time of system construction. Except as this subsection provides otherwise, an on-site wastewater disposal system must conform to the standards in this chapter, 18 AAC 72, and applicable portions of the Uniform Plumbing Code, as amended. In the event of inconsistency among these regulations and standards, the more restrictive shall apply. All solid pipe used in an on-site wastewater disposal system shall be cast iron, ductile iron, high-density polyethylene, PVC rated by the American Society of Testing and Materials (ASTM) and labeled D3034, or an approved equal pipe.

B.

An on-site wastewater disposal system must have a design and actual operational capacity sufficient to dispose of 150 gallons of wastewater per day per bedroom.

C.

A lot with an on-site wastewater disposal system must have an original subsurface disposal field and one replacement site.

D.

The location of a well, on-site wastewater disposal system or subsurface drain, either separately or in combination with each other and other wells, on-site wastewater disposal systems or subsurface drains in the vicinity, shall not have the effect of prohibiting future residential use of an adjacent lot or parcel. The department may require an agreement and necessary easements with the owner of the affected property for the sharing of a well or other resolution of the problem. The agreement shall be recorded.
