The New Water System at Springfield.
The Little river water system, that will insure, at a cost of $2,000,000, an ample supply of good water for Springfield, Mass., will have a reservoir of 2,478,000,000 gallons capacity. The diversion dam which will help to impound this water will be about 600 feet wide, 100 feet high and 60 feet broad at the base. It is curved in shape, the arch of the curve being up stream, making the resistance greater in accordance with the increase in pressure. The upstream side has a sheer vertical height of 100 feet and the water passes through a 4,800-foot tunnel, in Cobble mountain, to a sedimentation basin and thence to the filter galleries, which are of concrete and have an area of 5 acres. O11 its way from the basin to the filters, it passes through a hydro-electric outfit, the turbines of which supply light and power for the works. Front the litters, through a 36-inch main, the water flows into a great storage reservoir 8 miles away, on Provin mountain, whence it is delivered in the city, at a distance of 5 miles, under a pressure of 200 pounds to the square inch. The water travels in all about 3o miles before it reaches the city and the source of supply, in the Little river, which is a branch of the Westfield river, is regarded as unquestionably good, while the quantity available, at all seasons, gs practically unlimited.
