PARK CITY, UT. (January 17, 2023) — The Snyderville Basin Water Reclamation District calculates a monthly “flush Index” for the purpose of estimating the number of visitors (visitor nights) that were present in the Park City/Snyderville Basin area. Listed below is the latest monthly index with a comparison from the previous year.

December  2022 Visitor Nights “Flush Index”% Difference from December  2021
    230,856 +/-   8.2% Decrease

The “Flush Index” is based on historical wastewater flows measured by the Snyderville Basin Water Reclamation District. Actual methodology involves a statistical model that considers the quantity of wastewater, the strength of wastewater, monthly visitation patterns and an adjustment for rain or snow melt water seeping into the system.

 “Tip of the Month”

Prevent sewage back-ups and protect the environment by placing food waste in the trash and not down the drain!
