Secondary Water Rates
Secondary water will be accessible to residents in the available area of the city beginning towards the end of April 2012. Below you will find information to assist residents in preparing to connect to secondary water.

Explanation of Components and Parts
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.
