Clinton On-Call Water & Sewer Projects

About This Project

Since 2008, WithersRavenel has provided engineering services for design, surveying, easements, permitting, bidding, stakeholder and grant coordination, and construction administration/observation services for the following water and sewer installations:

  • Water System Infrastructure Improvements (2012): Replacement of existing old and undersized water lines in an older section of the city
  • Smith Street Drainage Basin I&I Study (2012): WithersRavenel performed a study of inflow and infiltration in a particular area of town. Services included CCTV and NASSCO assessment of approximately 3,000 LF of 8, 10, and 12-inch gravity sewer pipelines and a desktop analysis of the pump station using runtimes compared to daily rainfall and generally accepted sanitary sewer flow rates. The project resulted in the further pursuit of manhole rehabilitation projects which have yet to receive funding.
  • Eliza Lane Water, Sewer, and Streets (2011): Installation of 2,055 LF of 6-inch water line, 1,590 LF of 8-inch gravity sewer, 930 LF of 4-inch force main and 80 GPM lift station, and 2,100 LF of street and drainage repairs to serve existing low-to-moderate income housing areas and eliminate failing septic tanks, wells, or undersized water lines and failing street systems.
  • Pugh Road Water and Sewer (2010): Installation of 1,510 LF of 8-inch water line and 680 LF of 8-inch gravity sewer.
  • Russell Street Water and Sewer (2009): Installation of 1,900 LF of 6-inch water line and 1,730 LF of 8-inch gravity sewer.
  • Pugh Road Pump Station (2008): Construction of a 180 GPM pump station, 3,600 LF of 6-inch force main, and 2,600 LF of 8-inch gravity sewer.

In addition, WithersRavenel built the City’s infrastructure GIS database from the ground up. To initiate the program, WithersRavenel conducted a land use study and address verification effort, which involved traveling to every structure in the City, photographing it, labeling it with the type of structure (civic, commercial, residential, etc.), and determining whether its address was displayed correctly. Incorrectly addressed buildings were sent a notice with guidelines on how to properly the address. Next, WithersRavenel conducted an inventory of all water and sewer infrastructure in the City, totaling almost 2,000 fire hydrants, water valves, blowoffs, air release valves, and other features. Then WithersRavenel performed survey-grade mapping for more than 1,800 sewer manholes; manholes were located and assessed according to NASSCO assessment standards. With this data, WithersRavenel was able to implement a methodology for a fire hydrant assessment and maintenance and valve exercise program. Finally, WithersRavenel implemented a work order and asset management program accessed via a secure Web- and mobile-based client.
