An ordinance (PDF) enacted by the City Council in August 2014 concerns sewage and storm system surcharge and backup prevention claims. The ordinance requires properties where sewer connections are considered 'at risk' for sewer backups to have backwater prevention devices (such as backwater valves) installed to reduce the risk of sewage backup. These properties are identified as "designated connections." The presence or absence of a backwater prevention device at a designated connection will affect how future sewage back-up claims are processed, as specified in the ordinance.
Backwater Device Maintenance
For backwater prevention devices located on your property, you are responsible for inspection and maintenance during your period of ownership. The following video details how to maintain your backwater prevention valve.
