Pool Draining Guide for Properties with Septic Systems
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.
