City of Spartanburg Storm Sewer Assets
The City of Spartanburg currently owns or maintains a large and varied storm water system, including approximately 65 miles of storm water pipe ranging in size from 12 to 72 inches. Generally this includes pipes that are located in the Right-of-Way (ROW) of City-maintained roads. The median year of installation for the pipes is 1975 and the average pipe age is slightly more than 30 years. The City also maintains more than 5,000 storm drainage structures (drainage manholes, catch basins, pipe headwalls, etc.) that are located in the City’s right of ways.The vast majority of the storm water infrastructure in the City was installed by private developers, most of which has been dedicated to, and accepted by, the City for maintenance. The South Carolina Department of Transportation also installs storm water infrastructure under their various programs in their Right-of-Way.
Proposed Management Approach
Managing these assets as they become older and less able to perform as designed will be costly. However, these costs can be minimized if the assets are consistently maintained and actively managed over time. The EPA & S.C. Department of Health and Environmental Control (DHEC) has recognized this need and is promoting practices, such as Asset Management, that allow utilities to address existing needs now and minimize the cost of management as the infrastructure ages.
State Regulations
DHEC regulations regarding Storm Water Management require the City to address six minimum measures:
- Public education and outreach on storm water impacts
- Public involvement and participation
- Illicit discharge detection and elimination
- Construction site storm water runoff control
- Post-construction storm water management in new development and re-development
- Pollution prevention and good housekeeping for municipal operations
