A water main extension from the Danbury town line north up Federal Road to the Brookfield Four Corners area would require about 8,000 feet of water main and would cost about $1,500,000.

Once reaching the Four Corners (Routes 7 and 25 intersection area) it would connect with the Brookfield Water Company (BWC), which as of 2005 is just in the process of constructing its water system. It reportedly has approval for two wells with a combined yield of 140,000 gallons per day.

An interconnection has also been constructed to allow the BWC to purchase water from the United Water System in New Milford to the north. The piping along Route 7 from the Newbury Village Condominiums in Brookfield north to the New Milford town line is complete.

A meter building is to be constructed in Brookfield near the New Milford town line. Thus the BWC’s mains would serve as an intermediary to any regional connection between Danbury, Brookfield and New Milford.

Purchases of water by BWC from United Water will be limited to less than 50,000 gallons per day unless a DEP Diversion Permit is obtained in the future for a higher amount. There are no plans to obtain the permit. The BWC does not have a Water Supply Plan or projections for future use. Robert Parker, BWC President, reported that the current sources are expected to be adequate for the next 10 years.

Note that the United Water System is at HGL 463, which is higher than the BWC System HGL 403. Thus the BWC pressure will have to be increased to HGL 463 or a pressure reducing valve installed in order to serve the BWC System from the United Water System.

As noted above the BWC System operates off a hydropneumatic tank, which does not provide fire protection. An atmospheric tank would be required in Brookfield to provide adequate storage for fire protection. The cost of the storage tank would be range from $500,000 to $1,000,000.

The United Water Connecticut New Milford System currently has adequate source of supply, but the system demands are growing rapidly and are projected to have margin of safety of less than 15% for peak day demands after 2020.

The existing safe yield is 1.822 MGD (1.336 MGD without Well No. 5) and the maximum available water is 2.430 (1.782 MGD without Well No. 5). The 2001 consumption (the highest recorded to date) was 1.235 MGD with a margin of safety of 1.08, maximum month was 1.366 MGD with a margin of safety of 0.95, and peak day was 1.852 with a margin of safety of 0.96. Well No. 5 is in use, but can not be currently included in the available supply calculations because the ground around the well is below the 100-year flood level. United Water Company is working on corrective measures for Well No. 5 and expects to have the improvements made within the next two years.

With Well No. 5, the water system would have adequate margin of safety through 2020. In 2004, the average day demand was 1.08 MGD, the maximum month was 1.21 MGD, and the peak day was 1.52 MGD.

For 2050, if additional wells are not developed in New Milford, the United Water System would need 0.25 MGD for average day, 0.47 MGD for maximum month, and 0.67 MGD for peak day, in order to provide a margin of safety of 1.15.
