Public Hearing on Proposed Development Impact Fees
Post Date: 11/14/2018 - In accordance with Arizona Revised Statute 9-463.05, the City of Avondale is holding a public hearing to accept comments on the proposed development impact fees. The public hearing will be held at Avondale City Hall at the City Council meeting scheduled: Monday, January 14, 2019, City Hall Council Chambers, 11465 W. Civic Center Drive, Avondale, Arizona 85323 at 7:00 pm. City Council reviewed the Land Use Assumptions and Infrastructure Improvement Plan on Monday, October 15, 2018.
It is the City’s responsibility to protect customers from contaminated water. The backflow prevention assembly is the key to preventing unwanted substances from entering our distribution system. In case of a drop in the city’s water pressure, the backflow device will stop water from flowing in reverse and possibly contaminating the drinking water supply.
Backflow might occur either by back-pressure or back-siphonage. Back-siphonage can be caused by high velocities in pipes from maintenance, line breaks, or fire fighting. Back-pressure occurs when the pressure at the point of use is higher than the supply pressure. Sources of back-pressure include booster pumps, boilers, elevated piping, and interconnections with auxiliary systems.
Cross Connection is any actual or potential physical connection between a public water system or the consumer’s water system and any source of non-potable liquid, solid or gas that could contaminate the potable water supply by backflow. Examples of “cross-connections” are: post mix soda machines, soap aspirators, chemical injectors, cooling towers, boilers and chillers connected to the potable water supply.
Public Works staff tracks the results of annual backflow prevention assembly testing which are to be conducted by Certified Backflow Assembly Testers.
Customers are encouraged to assist with the success of this program by attaining the proper permits for plumbing changes including new irrigation installation and arranging for annual testing of existing assemblies by a certified tester.
One way to deter the theft is to spray paint the assembly according to code as light tan or color to match the building or screen wall. Be careful not to paint over the ID tag and serial number. The paint makes the metal less valuable when melted down and recyclers won't take it.
Backflow Preventer Assemblies are critical to preventing contamination of the water supply. If you see any suspicious activity near or around these devices please contact the Police Department at 623.333.7000.
