Aquarion Water Company of Connecticut’s Ridgefield System currently has an adequate source of supply, but the system demands are growing rapidly and are projected to have margins of safety of less than 15% for peak day demands by 2020.

The existing safe yield is 1.689 MGD and the 2003 consumption was 0.89 MGD.

In 2004, Aquarion applied for an increase in its diversion limit from the Aquarion Main System from 1.15 MGD to 1.30 MGD. With this increase, the Ridgefield System will have adequate supply through 2030, but would need up to 0.4 MGD to provide a 15% margin of safety for peak day demands in 2040. DEP has published its intent to approve the request.

The Aquarion Ridgefield System also has two small interconnections with the Danbury system at Barnum and McKeon Places in north western Ridgefield. These are isolated small service areas with no regional significance.

One of the alternatives evaluated in the Diversion Permit application was an interconnection with the City of Danbury along Route 7. The main supply for the interconnection would be from the Spruce Mountain Tank (El. 760) with a capacity of 1,500,000 gallons.

This is Danbury’s West Lake High Service Area. The tank is located on a hill south of Danbury Airport and is some 25 feet higher than the Ridgefield Low Service Area hydraulic grade line (HGL) 735.

The potential interconnection to the Danbury system would include 17,500 feet of 12-inch main and two stream crossings. With a 12-inch main, the supply available to Ridgefield by gravity would be up to 0.6 MGD (less consumption in Danbury).

This is the supply available to the low service area HGL 735. The Ridgefield main service area is at HGL 960, and would require pumping to be served from Danbury. No additional pumping stations or other improvements would be required within the Danbury system.

The estimated cost of the interconnection and pumping station to supply the Ridgefield main service area is $4.0 million, and this does not include the cost of purchasing the water.

David Connors of Aquarion confirmed that, assuming the current Diversion Permit application is approved, the Ridgefield System should have adequate source of supply through 2030, thus Ridgefield will not need to consider an interconnection with Danbury in the short term.

In addition, a January 5, 2006 comment on this potential interconnection was that "The City of Danbury does not want to encourage inappropriate growth and development along the southerly section of Route 7 by the installation of a water main in Route 7."
