4.0 CAPITAL IMPROVEMENTS PLAN
Goal Statement: The goal of the Town of Siler City is to provide clean, safe, and
economical water and sewer service that meets existing standards and protects public
health and water quality for the foreseeable future. The Town currently serves residential
households and businesses within the Town and in nearby surrounding areas. Siler City
strives to provide and maintain a reliable and safe water supply, water distribution system,
wastewater collection system and wastewater treatment system.
The purpose of this asset inventory and assessment was to document the condition of
the Town's inventoried infrastructure to assist the Town with becoming more viable and
proactive in the management and financing of its wastewater system. The Town
continues to look to its CIP to guide its next projects; therefore, it is vital that the CIP
remains current to the Town's highest priorities and provides accurate cost estimates.
The development of this AIA will serve as a positive step towards ensuring that the Town
can maintain its level of service agreement.
Throughout the AIA process, the Town's entire sewer system was evaluated through
visual inspections, CCTV footage, smoke tests, and flow monitoring. The highest priorities
were collected and put into a twenty-year capital improvements plan. In this plan, the
WWTP, the large interceptors, and aged VCP lines were targeted to meet the future
needs of the Town and to comply with current and future limitations.
Reducing Ill at the wastewater treatment plant is a major goal of the AIA, assessments of
the wastewater treatment plant infrastructure led to replacing the interceptor lines, smoke
tested lines and I/I study lines as they are known to allow Ill into the system.
McGill updated the cost estimates for all projects based on current materials and
construction costs. The updated CIP is intended to be adopted by the Town to guide its
selection of sewer system improvement projects over the next decades. The cost
summary for the 20-year CIP is shown below in Table 36.
