Featured Video: System Pressure, Fire Hydrants, and Cross Connections

Featured Video: System Pressure, Fire Hydrants, and Cross Connections
Last week, we featured two videos that went into detail on backflow and the assemblies and practices that can prevent it. This week's video deals with backflow also, but it places the topic within the broader context of distribution system maintenance at a smaller utility. It features an interview with Scott Roselle, the water and sewer lead at a utility serving a town in Michigan. In this 4-minute interview, Roselle discusses pressure districts, fire hydrant maintenance, and cross connections, including both general CCC topics and the specifics of mitigating cross connections with residential swimming pools and in commercial buildings. If you want to see how another smaller utility handles distribution challenges, check it out:

No one wants to experience a backflow incident. Depending on what contaminant was involved and how much of the distribution system was affected, these incidents range from being a lot of work and expense to being a full-blown public health crisis. (See the bottom of this page to browse real backflow incidents that have occurred here in the U.S. as well as Australia and Canada.) Either way, a lot of people will have their water service disrupted and you'll have a lot of extra work on your hands until the situation is resolved.

If you're hoping to prevent a backflow incident in your community, this week's videos, courtesy of AWWA, could help. The first video explains the basics of backflow and backsiphonage and provides a brief overview air gaps and backflow prevention assemblies. The second video covers similar topics but goes more in-depth on backflow prevention assemblies, discussing the most common models, how they work, and where and how they should be installed. The first video is about 5 minutes and the second is about 7-and-a-half.
