New Hampton Road Water Main Project

New Hampton Road Water Main Project

Tata & Howard recently completed design, funding, and construction phase services in the City of Franklin, NH for the $3.5M New Hampton Road Water Main Project. The new 16-inch and 12-inch ductile iron water mains replaced a 1940’s era unlined cast iron water main (approximately 14,000 linear feet) with a history of main breaks and extends over three (3) miles from the Babbitt Road Booster Station to the Sanbornton Wellfield.

The water main was identified as a priority in the 2016 Capital Efficiency Plan prepared by Tata & Howard and will provide improved water quality, distribution pressure, and fire protection.

Tata & Howard assisted the City with maximizing the NHDES SRF Loan with the City’s paving program funds to fully reconstruct 9,000 linear feet of New Hampton Road as part of the project.

Park Construction Company of Fitzwilliam, NH was the General Contractor for the project which was initiated in March and completed on time in November of 2020 following all recommended Covid-19 protocols.

Falmouth Main Street Water Main Construction

Falmouth Main Street Water Main Construction

Tata & Howard was contracted to provide design, construction administration and resident observation for the installation of 18,000 linear feet (approximately 3.5 miles) of 16-inch ductile iron water main in Falmouth, MA. Water main replacement will be in Main Street and Route 28. That is, from the intersection of West Main Street and Locust Street, to the intersection of Teaticket Highway and Oxbow Road.
New water main will be replacing the town’s 10-inch cast iron water pipes that were originally installed in 1898. Falmouth’s 121-year-old water infrastructure has stood strong for more than a century; however, it has become clear that it’s nearing the end of its useful life and approaching the age at which it needs to be replaced. Evidence of this can be seen in the three water main breaks that have occurred since August of 2018. In addition, the original water main is hydraulically deficient and needs to be up-sized to meet the increasing demands in the system.
Construction began at the beginning of April and continued up until Memorial Day of this year. Construction was placed on hold during the heavy tourist months in Cape Cod and will resume after Labor Day. Project completion is expected in 2021.



Chamberlain Highway Receives New Water Main Connections

Chamberlain Highway Receives New Water Main Connections

The Chamberlain Highway in Meridan, Connecticut has 536 linear feet of new 16-inch ductile iron main and two new fire hydrants. After Tata & Howard completed several test pits to verify connection locations at each end of the new main, construction work started on May 3, 2018 with the installation of a 16” x 16” tapping sleeve and valve at the north end of the project. This existing water main at the north end connection was originally installed in 1894.

Chamberlain West MainWork progressed south until the new main was approximately 50 feet away from the other connection point in West Main Street. Connections to the existing main in West Main Street was performed over a 36-hour period due to the complexity and amount of utilities around the service connection, including a live 24-inch water main five feet away and multiple telephone conduits located 6 inches above the replaced main. Tata & Howard personnel on site at all times to observe that work was in performed in accordance to the plans and specifications.

Following the completion of the Chamberlain Highway water infrastructure improvement project, work to replace two water mains on the state-owned bridge crossing Sodom Brook in Meridan will begin.

A Decade of Infrastructure Improvements

Wiscasset Completes Capital Efficiency Plan™ Infrastructure Improvements

The Wiscasset Water District (WWD) completed its final phase of water main replacements for the Town of Wiscasset, ME. In 2007, Wiscasset, a rural coastal town in Maine, embarked on a long-awaited infrastructure improvement program to replace the Town’s century-old waterlines. The Wiscasset Water District, engaged Tata & Howard’s services in 2010, to prepare a Capital Efficiency Plan™ (CEP), to identify areas to the Town’s water distribution system needing rehabilitation, repair, and/or replacement.

CEP reportThe Capital Efficiency Plan™ report which included hydraulic modeling, system criticality, and an asset management plan, provided the Utility with a database and Geographic Information System (GIS) representation for each pipe segment within their underground piping system. The CEP report also prioritized the water distribution system piping improvements and provided estimated costs to replace or rehabilitate the water mains.

Wiscasset Main StreetIn response to the CEP™ findings, the Wiscasset Water District retained the services of Tata & Howard, to perform design, bidding, construction administration, and resident project representation services for a series of water main projects.

Phased over 10 years, the plan included replacing 33,150 feet of 12-inch and 8-inch piping, installation of a water storage tank mixer, SCADA upgrades, and office landscaping improvements.

The final phase of water main replacements is scheduled to be completed during the summer of 2018 and will fulfill all the Priority I water main improvements identified in the 2010 CEP™ report. The projects were funded in part by a combination of USDA Rural Development grants (6 total) and loans (7 total), as well as coordination with the Maine Department of Transportation and Rural Development.

With the water main improvements nearing completion, the Wiscasset Water District has retained Tata & Howard to reevaluate its 2010 Capital Efficiency Plan™. The revised plan will update the water main inventory database and review additional recommended water distribution improvements.

New Water Main, Whitinsville Water Company, MA

New Water Main, Whitinsville Water Company, MA

Tata & Howard provided engineering services for the design, construction administration, and resident project representation for the installation of approximately 3,800 linear feet of 8-inch ductile iron water main on A, B, C, D, and Border Streets for the Whitinsville Water Company. All homes in the project area are multi-family ranging from duplexes to four units per building, and are of wood construction. The area has a history of fires, so fire protection was of utmost concern.

The project began in February of 2016. Each home had its water service replaced, and also received a 6-inch ductile iron water main that was installed with a gate valve and a cap so that the homeowner could install individual fire and water services to each unit. For example, the homes with four units could be tapped with eight new service lines, giving each home a fire service and a water service and increased protection from fire. As added fire protection, Tata & Howard also replaced all hydrants and added four additional hydrants to the project area.

All water main installation was completed in November of 2016, and final paving is scheduled to take place in the spring of 2017.
