The disposal of water from a swimming pool and/or spa for properties serviced by a septic system always poses a unique challenge.

Section 11.4 of the SNHD Regulations Governing Individual Sewage Disposal Systems and Liquid Waste Management PDF 1MB pursuant to Nevada Revised Statute (NRS) 444.650 has the following restriction:

“The disposal of water from swimming pool or spa into or over the septic system is prohibited. The disposal of backwash waste from pool or spa filters into the septic system is prohibited.”

Essentially, the septic system would be overloaded and fail if water from a swimming pool or spa is drained into or over it.

Draining Instructions/Options

1. Dechlorinate the water in the swimming pool/spa and arrange to have it pumped by a liquid waste hauler for disposal at a wastewater treatment plant - this option can be expensive because multiple trucking trips may be required based on the capacity of the pool. Listings of liquid waste haulers can be found under “Septic Service” in the Yellow Pages.
   
   
2. If there is an existing sewer manhole in close proximity to the property, you can check with the sewer agency of jurisdiction to get permission to discharge the dechlorinated water into the sewer manhole (this is dependent on direction in which the sewer line drains and if it is a collector line).*

It is a municipal code violation to drain a swimming pool/spa into the street. Additionally, drained water could become a breeding place for mosquitoes, which constitutes a public health hazard.
