WATER AND SANITARY SEWER SUPPLIES

Water Supply

The water supply map displays the area currently served by city water distribution lines. This is the area where city water is available and there is very little if any dependence on private wells,

Presently there are two major sources of water which feed the demand produced by the businesses and homes in this area. These sources are the Mount Higby Reservoir in the Westfield Section of the city and the River Road well fields along the Connecticut River. A third less utilized water supply is the Laurel Brook Reservoir. This reservoir is located in the southwestern corner of the city at the municipal boundary with Middlefield. In order to achieve maximum utilization of this supply, a water filtration plant is necessary.

Currently the peak demand for water in Middletown is approximately 5.4 million gallons per day. To satisfy this demand, the River Road facility provides approximately 4.0 million gallons per day and the Higby Reservoir provides approximately 1.4 million gallons per day.

Considering an ultimate target population of 65,000 residents, as projected in the population and housing portions of this plan, the anticipated peak demand would increase to approximately 10.0 million gallons per day.

Water and Sewer Department projections indicate that this future peak demand can be met with the three existing facilities, provided that the Laurel Brook filtration plant is on line. The River Road Well fields and Higby Reservoir would serve as the primary water sources with the Laurel Brook Reservoir acting as a reserve.

Clearly, planning for an ultimate population of 65,000 residents, which primarily entails providing for a zoning scheme which targets this population, will avoid future expenditures which would be necessary to access additional ground water supplies.

Adequate supply is one of the two main considerations. The second consideration is water quality. It is essential that the quality of these supplies be protected and improved wherever necessary. For this reason, the city should update and strengthen the section of the Zoning Code regarding the Protection of Water Resources.

Public Act 89-305 as amended by 90-275, An Act Concerning Aquifer Protection Areas, requires both detailed mapping of public ground water supply aquifers and land use regulations which restrict uses over aquifer recharge areas. These additional land use restrictions must be designed so as to avoid potential groundwater contamination. In Middletown, the area involved is the River Road well field. This plan is in full support of this state initiative.

In conclusion, the city should continue to study the city’s water sources, on a long range basis, first to insure an adequate supply of potable water for the City’s ultimate population, and second, to plan for the gradual improvement of the distribution system, including new principal mains and extensions to new areas where necessary. This would include areas where available groundwater supplies are inadequate to support the existing development and where ground water supplies have been contaminated and are no longer potable.

SANITARY SEWERAGE

The sanitary Sewerage map displays the area served by sanitary sewer lines. The effluent produced from these areas of the city either flows to the City’s treatment plant along River Road or to the Mattabassett Regional treatment plant adjacent to Route 9 in Cromwell.

To be more specific, all effluent from the areas north of Westfield Street and west of Newfield Street is treated at the Mattabassett Regional treatment facility. The effluent produced from all other areas served by city sanitary sewer is treated at the River Road treatment plant.

After the effluent is treated at the River Road facility, the remaining sludge is transported by rail to the Mattabasset facility for incineration. The ash which remains after incineration is then transported to an ash disposal site in Berlin.

Currently, the peak flow to the two treatment plants is approximately 4.0 million gallons per day. The capacity of the River Road facility is estimated to be 6.1 million gallons per day.

Considering an ultimate target population of 65,000 residents, as projected in the population portion of this plan, the anticipated peak flow would increase to approximately 8.0 million gallons per day.

Water and Sewer Department projections indicate that this future flow can be treated with the River Road facility and the Mattabassett Regional facility.

FUTURE EXTENSIONS OF SEWER AND WATER LINES

Future extensions should be carefully scrutinized by the Water Pollution Control Authority and the Planning and Zoning Commission. It is recommended that the Water Pollution Control Authority continue to hold a public hearing for major extensions. This public hearing should occur prior to any application to the Planning and Zoning or Inland Wetlands Commission. As a general policy, the Water Pollution Control Authority should avoid water and sewer extensions into those areas designated as conservation areas and rural areas in the State Plan for Conservation and Development.

When considering extensions, the Water Pollution Control Authority must take into consideration the guidelines, in terms of public facilities, set forth in the State Plan for Conservation and Development, the applicants environmental assessment, comment from Water and Sewer Department staff including the Environmental Manager, the City Planning staff, resolution or prevention of health problems, improvement to quality of life and cost effectiveness. Where it is found to be impractical, uneconomical or environmentally unacceptable to extend service to some of the higher and more rugged areas, where zoning allows for only sparse development, extensions should be discouraged. Additionally, the Planning and Zoning Commission should consider and promote open space (cluster) subdivisions which allow for the same number of units on a smaller area of land. While the remaining less developable land is left undeveloped. In terms of water and sewer lines, streets and other utilities, it is much more efficient, cost effective and environmentally sound to service this more compact development.
