Harwich Water Department Projects
Contractor: Weston & Sampson Engineer: Polaris Consultants LLC
Project Overview: Under the Supervision of the Board of Water Commissioners and Superintendent, the Harwich Water Department constructed a 6.5 MGD Greensand and Manganese removal plant. Public sealed bids were opened in March of 2010; the low bid was then awarded to Weston & Sampson Inc. for $3.25 million dollars. This plant will be used to remove approximately 80% of the iron and manganese which occurs naturally in the type of soil formation on Cape Cod. These types of plants can be found in all of our surrounding Towns. Harwich has now joined the surrounding Towns in treating for iron and manganese. For the last 10 years the Harwich Water Department was able to blend water with little to no iron and manganese with the water that had higher levels of iron and manganese which kept iron and manganese to a minimal level. However, with the demands growing during our summer months we were no longer able to continue the blending process.
There was an open public ceremony which took place on November 16, 2011 at the new Bruce Cahoon Treatment Facility where Bruce Cahoon’s family was in attendance. The Bruce Cahoon Treatment Facility came on line November 20, 2011.
Contractor: Amstar of Western New York Engineer: Haley & Ward
Project Overview: The Route 39 waters storage tank underwent extensive structural repairs this year. The last time this tank was painted was 14 years ago. The Route 39 tank is a spider leg tank. The Harwich Water Department has two of these tanks. The second one is the Lothrop Tank. The Route 39 tank had severe metal lost around the area where the bowl and legs come together, around the catwalk as well as the sway bars on the tank. Another costly item was that the tank had to be completely shrouded because of lead paint issues.
The project engineers on this project were Haley & Ward Inc. out of Waltham MA. Inspection services were conducted by Merithew Inc. out of Raynham Center, MA. Structural repairs and painting were done by Amstar of Western New York, Buffalo, NY.
This project went out to bid according to Chapter 30 Laws. Publicly sealed bids were then opened on February 2010. The award went to the low bidder, Amstar of Western New York at a price of $2,050,000. The final cost of this project was $2,050,000. It was completed within the allotted time schedule and within budget.
