Indian Head Water Storage Tank Replacement
The water tank located off Indian Head Heights is a key asset in Framingham's water distribution system. The 3.5 million gallon tank provides storage for over half of the average daily water demand in the City's distribution system.
Initially installed in 1939, the tank is aged and needs to be replaced. Due to its current condition, age and the critical nature of this tank, it is not reasonable to take it out of service for extensive repairs.
Two in Place of One
To continue providing high water quality and fire protection, two smaller tanks will replace the existing tank for a combined total of 3.5 million gallons. The smaller, narrower profile of the two tanks not only sit better on the site they will allow redundancy in the system when repairs are needed. The project site design has considered access, security, stormwater management and landscape screening improvements.
Due to the requirement to maintain water supply and fire protection services to the City during this construction, the existing 3.5 million gallon storage tank must remain in service while a new replacement tank is constructed. The installation of two smaller 1.75 million gallon tanks has been scheduled to be constructed over a two-year phased replacement period. The two tank configuration will provide redundancy to ensure uninterrupted water and fire service, improve the water supply and distribution system’s overall efficiency and provide enhanced operation and maintenance flexibility for the lifetime of the tanks.
Additional work will be also conducted as part of this contract such as the new water main to feed the tanks (from the intersection Indian Head Road - Indian Head Heights), installation of drainage improvements (Northern end of Indian Head Heights), and repaving of Indian Head Heights Road.
Final design is complete and construction bids have been advertised. Construction is anticipated to begin in April of 2017. Construction of the two tanks is expected to take two years with completion planned for Fall of 2019.
This project is currently on schedule with the originally anticipated completion date.
The following activities have been completed so far: Dome and wall panels for tank #2 are in place. Prestressing and concrete coating work around tank #2 are currently ongoing. About 50% of the retaining wall has been completed so far.
Filling and disinfection activities for tank #2 are scheduled for next month as well as continuation of work on the retaining wall and site grading.
