Elevated Water Storage Tank Rehabilitation, Borough of Milltown

Project Background
In 1992, CME Associates, then Borough of Milltown Municipal Engineer, designed a 750,000-gallon water storage tank as part of a $3.3 Million Multi-Phased Water System Improvements project. The other projects associated with the Multi-Phased Water System Improvements were a new 20" Transmission Main and a 2.0 MGD Water Pumping Facility located at Elkins Lane, within the Borough. The construction of the 750,000-gallon tank began in the fall of 1993 with excavation for the approximately 200 cubic yard concrete footing to depths of 20'-25' below existing grade, due to poor site conditions. The tank was completed and successfully placed into service in September 1994.

The purpose of Tank Rehabilitation
By 2017, after over two decades of continued beneficial service and in an effort to extend its useful life, the Borough authorized CME Associates to rehabilitate and upgrade the elevated storage tank. CME was tasked with incorporating new tank coating technology advances to rehabilitate the tank and related equipment. Further, taking advantage of prevailing favorable funding terms from the New Jersey Environmental Infrastructure Financing Program (NJEIFP), the Borough applied for and secured all the funding needed to complete the project. The NJEIFP is a State Revolving Fund program jointly administered by the New Jersey Department of Environmental Protection (DEP) and the New Jersey Environmental Infrastructure Trust (Trust) and uses a combination of funds provided by the United States Environmental Protection Agency, the DEP, and the Trust to provide very low-interest loans to borrowers for environmental infrastructure projects.

Project Benefits
This project will provide water quality benefits by extending the useful life of the water tank which provides storage of potable water for the Borough for use during peak demand periods and for fire demand reserves for residents and businesses in the Borough of Milltown.

CME provided Construction Administration during the Water Tank Rehabilitation. Services provide included coordination of operations with the Borough Water System Operator, coordination of relocation of cellular telephone equipment to facilitate the rehabilitation, observation of the Contractor's work, inspection of surface preparation and coating application. In addition to the rehabilitation of the Water Tank, the project included upgrades to the disinfection system at the Borough's Elkins Lane Booster Pumping Station and improvements to the telemetry system which monitors the water level in the water tank and provides alarms to the System Operator.
