Septic Eligibility for New and Existing Properties

The following documentation related to water and sewer service must be included with all septic permit applications:

• Proof of an approved water source:
  • Properties within the Las Vegas Valley Water District (LVVWD) service area must obtain written approval from LVVWD.
  • Properties within the Moapa Valley Water District (MVWD) service area must provide a Conditional Water Commitment letter.
  • Properties with an existing or proposed well must provide a well log (well driller’s report) and must obtain appropriate water rights as necessary (contact the Nevada Division of Water Resources for additional information).
• A letter from the sewer agency with jurisdiction stating that connection to the community sewerage system is not available. This letter is alternatively referred to as a “Letter of Sewer Non-Availability” or a “Point of Connection Inquiry Letter.”

ISDS (or Septic System) Submittal Details

New septic plans are submitted online to septics@snhd.org. The Southern Nevada Health District will process the paperwork and send an invoice for payment. Upon payment, the applicant will be placed in line for review. The order of review is based on age. The Health District plan reviewer will review the material selected / design / capacity of the septic system, evaluate setbacks and provide corrections as necessary.
