Requirements before using secondary water:
- Customer must call for an inspection of their sprinkler connection to the secondary service line. (See instructional video below)
- Customer must have a current backflow assembly test report if using culinary and secondary (swing line connection) for irrigation.
- Customer must request secondary water meter to be set after they have passed inspection and have a current backflow assembly test report.
The Herriman City Water Department has completed a water rate study, which was performed by Zions Bank Public Finance. These studies are generally conducted every 1-2 years to ensure our water revenues are staying in line with our debt service obligations and O&M costs. The last water rate study was performed in the summer of 2012. Here is a link to the rate findings presentation for Culinary and Secondary water rates. A map has been provided to point out the areas of the City which currently have secondary water available and areas which could potentially have access in the future. If you have questions, feel free to contact the Water Department at 801-446-5323 or email@example.com.

Explanation of Components and Parts
Secondary Water Meter Box – Item installed by Developer for City use only. This is usually a green sprinkler box or a cast iron oval meter box. Home owners are responsible for hooking up to the line outside the box. Do not connect to anything inside of the meter box. The City will install a secondary water meter after the connection has passed inspection.
Stop & Waste Valve – The stop & waste valve serves two basic purposes. It is used for turning water on or off and for draining water out of the sprinkler system. The valve must be fully open or fully closed to operate properly.
Filter (optional) – We recommend using a filter. The secondary water will be filtered before it enters the distribution system. We are filtering it down to 200 microns. Check with your sprinkler professional for their recommendation on filtration for your particular sprinkler system.
Swing-line – A swing-line is only needed if you plan on using both culinary and secondary for irrigation. It is not needed if you choose to use only secondary for irrigation. A swing-line is used to ensure only one supply of water is being used for irrigation. In a swing-line box you have two supply lines coming in (culinary & secondary) each with a shut off valve and you have one line going out (sprinkler feed line). There is one flexible line that is permanently fastened to the sprinkler feed and a quick connector that can be connected to either the secondary or the culinary depending on which supply will be used.
Backflow Assembly – The recommended backflow assembly type is a Reduced Pressure Zone assembly (RPZ). A backflow assembly is needed anytime culinary water will or may be used for irrigation. If using culinary only for irrigation, the backlow assembly must be installed on the main sprinkler feed line before the tee, junction or the first set of control valves. If you are using culinary and secondary, the backflow assembly must be installed before the swing-line box. A backflow assembly is not required if secondary will be the only supply for your irrigation system. Backflow assemblies must be tested by a certified backflow technician within 10 days of initial use and annually thereafter.
