Bids received for water treatment plant and processing equipment

By Dotti Farrington

Only one of five bidders to build the town's new water treatment plant at Great Creek on North Main Road, was within the town's $4 million budget for the project, according to Stephen Goslee, the town's director of public works.

The contract covers a 4,200 square foot structure with new high tech water processing equipment to replace the 2,050 square foot plant and apparatus, currently in place.

Weston and Sampson of Peabody, Mass., offered to do the work for $3,836,000.

Other bidders were: Carlin Construction, a general contractor, of Waterford, Conn., $4,506,840; Waterline Industries, Seabrook, N.H., municipal utilities specialist, $4,847,577; R. Zuppo Corporation, Stoughton, Mass., marine and environmental contractor, $4,997,000; and Thielsch Engineering, Cranston, $5,214,750.

The water plant bids will be reviewed, verified and referenced by Fay, Spofford and Thorndike of Burlington, Mass., town water consultants and designers of the project. The review report is due July 16 for the next meeting of the Town Council sitting as the Board of Water and Sewer Commissioners.

Weston and Sampson, environmental and infrastructure firm, has won several awards for its innovations and construction work, that cover various utility projects including water treatment plants. It won last year's American Public Works Association award for its Arlington Reservoir Dam Rehabilitation project.

The treatment plant will be replaced as part of the 2004 bond issue for $6.2 million in water improvements, including the second water tower to be completed soon; and water distribution pipe improvements.

The town has spent nearly two years getting various permits to replace the water plant at its existing location at Great Creek. It needs one more permit, from the Coastal Resources Management Council (CRMC), that is expected soon, based on on-going work by town and CRMC officials, according to Goslee. The discussions involve creation of an acceptable mitigation area, including demolition of two storage sheds and planting a new grassed area to substitute for some wetlands to be disturbed or used as part of construction.

The town had to meet regulations for permits involving local planning and zoning rules, state health and environment regulations, and state plans for land use, outdoor recreation, Greenways, Greenspace, Community Forests, Rivers Policy, Narragansett Bay Conservation, water supplies, emergency response, drought management, and watersource management.

Water supply

FST said earlier this year that the new plant will meet existing maximum water needs of the 47 percent of island residents who have municipal water service. The new immersed membrane technology will ensure that the town meets the newest, more stringent, water-quality regulations that the existing plant cannot meet, according to FST. Speakers, officials, and reports at the mandatory hearing last February all emphasized that the increased water supply does not mean that the town can expand the municipal system,

The consultant said its design features state-of-the-art technology that will be 99 percent efficient, wasting only one percent of the water treated, instead of the 15 percent or more now lost during treatment

The technology results from pilot testing on the North and South Pond reservoirs with an ultrafiltration membrane treatment system from Zenon Environmental, a developer for water and wastewater treatment technologies.

High bidder

Thielsch, high bidder for the water plant, was the sole bidder for the major renovations and improvements now underway at the Jamestown Wastewater Treatment Plant at Taylor Point. Thielsch agreed to contract changes to bring costs within the town budget. The contract negotiation needed to be within the $2.6 million balance of the $7.5 million multi-project, multi-year sewer system upgrades.
