Serves Las Vegas valley, NV. Every point below comes from Las Vegas Valley Water District's own pages, linked; check your notice for your own deadline.
Who must test
- Backflow prevention assemblies for service protection (at the meter) are tested and maintained by the District, not by private testers hired by the customer. Source.
- A District-approved backflow prevention assembly next to the meter is required at the applicant's expense for all new commercial and industrial services, new fire services and new potable or non-potable irrigation services. Source.
Notices and deadlines
- When a survey shows an existing service needs a new or upgraded assembly, the customer is notified by mail and has 120 days from the notice to install it. Source.
Tester registration
- An assembly may be installed by a Nevada licensed contractor, but the installation must be approved, inspected and tested to District standards before the service is activated. Source.
Fees
- Assemblies two inches and smaller may be installed by a licensed contractor only after the property owner obtains a permit from the District. Source.
- Customers with backflow prevention assemblies pay a daily service charge for each assembly, based on assembly size, on top of other daily service charges. Source.
If a test is missed
- If the assembly is still not installed 180 days after the first notice (after a second notice at 150 days), service may be terminated and the District may install the assembly at the customer's expense. Source.
- Failure to give the District access to the assemblies is grounds for termination of water service. Source.
Program
- The District's cross-connection control (backflow prevention) program for service protection is set out in Service Rules section 6.12 and runs under NAC 445A.67185 to 445A.67255. Source.
