ValveTek’s Jeff Favina joins The Water Values Podcast to discuss main flushing and ValveTek’s use of the patented NO-DES flushing solution. Starting with the basics of main flushing, Jeff explains why main flushing is important from a water quality standpoint and outlines the conventional methods of main flushing. He then expands into the NO-DES flushing solution and demonstrates how it works and how it, importantly, does not waste water. The avoidance of water waste from the NO-DES system demonstrates how utilities can walk the conservation walk rather than imposing conservation measures on their customers.
In this session, you’ll learn about:
- What main flushing is
- Why main flushing is important
- What some of the common particulates are in water mains
- How a utility determines what sections of its network need to be flushed
- How ValveTek achieves disinfection from system to system and when making local connections
- The turbidity levels the NO-DES solution is capable of achieving (hint – it’s a very low Nephelometric Turbidity Unit, or NTU)
- How a single rig location can clean a large distribution network area
- How ValveTek tests the water quality in the distribution system pre-, during, and post-flush
- The areas of the country where the NO-DES flushing solution is most commonly deployed
