Herriman begins shutting down its secondary water system for the season

HERRIMAN — Herriman's secondary water system has begun its seasonal shutdown, the City said in a notice dated Oct. 13 1. Jordan Valley Water Conservancy District has already discontinued service to the Blackridge area, and residents in other parts of the city should expect secondary water pressure to gradually decrease over the coming days as the system is taken offline for the season 1.

The shutdown proceeds in stages, so exact timing may vary by area, and the City says some residents may notice reduced pressure before service stops completely 1. Residents who rely on secondary water for irrigation were asked to finish any remaining seasonal watering needs as soon as possible 1.

The City's secondary water page says the untreated irrigation supply is typically available each year between early May and mid-October 2. The City's water FAQ sets the window at May 1 to mid-October, states that secondary water is not treated and is not for human consumption, and says the City meters the secondary system to encourage conservation 3.

Secondary water reaches a property through a separate pipe network from drinking water. Herriman requires an inspection of a customer's sprinkler connection, and a current backflow assembly test report where culinary and secondary supplies are both used for irrigation, before the City will set a secondary meter 2.
