Economic Infrastructure Case Study:
Colleton County

Colleton County has been proactive in its effort to bring in more business and industry as well as jobs to its residents. Part of this effort included establishing an industrial park at the Lowcountry Regional Airport, South Carolina's largest general aviation airport.

The airport is jointly owned by the City of Walterboro and Colleton County and together these local governments have targeted the aviation industry for investments and recruitment within the airtport's vicinity. 

Recently, two new businesses were interested  in establishing their manufacturing operations at shovel-ready industrial sites at the airport. While utilities provided by the City of Walterboro were nearby, the sites were not served by water and sewer service.

Colleton County received RIA funding to extend water and sewer to the site. Total project costs were $1.7 million.

RESULTS: Two aerospace companies announced plans to create 166 jobs and provide $5.8 million in capital investment.

"The Lowcountry Regional Airport is a key asset in our community but we have had limited resources for its development. By providing us with the resources to install water and sewer infrastructure, the Rural Infrastructure Authority has been vital to our plan of attracting jobs and investment to the airport and surrounding properties.”

Basic Infrastructure Case Study:
Lancaster County Water and Sewer District

Lancaster County Water and Sewer District (LCWSD) has a "goal to improve the quality of life in [their] county by providing the highest quality water and wastewater service possible". And that is evident with the numerous awards and accolades the system has received over the years.

Yet even with regular maintenance including camera inspections, pressure cleaning and root cutting that are accomplished by the sewer system crew on a routine basis, their 40 year-old clay pipes have exceeded their expected useful life and increasingly are experiencing above normal infiltration and inflow (I&I), all of which leaves the system susceptible to sanitary sewer overflows.

In addition, the project area drains to another utility's sub-basin which is currently under an EPA Administrative Order of Consent, highlighting the need to address the problem in a timely manner. LCWSD secured RIA grant funding to install cured-in place pipe for more than 10,000 LF of pipes and manholes rehabilitation.

RESULTS: After project completion, initial flow data indicated a 57% reduction in the wet weather peaking factor. This reduction reflects the effort to keep sewer flow within the confines of the collection system for eventual treatment at the plant and limit the amount of I&I getting inside of their sewer system, thereby positively impacting the environment.

“The funding provided by South Carolina Rural Infrastructure Authority will assist LCWSD for generations to come in making this area of our collection system better to serve our customers. Our rehabilitated sewer collection system minimizes the chances for sewer overflows in this area, helps protect our environment, and helps our receiving entity with added capacity in their system.”
