January 20, 1916: Municipal Journal article–New Filtration Plant Completed. “Lowell, Mass.-The city’s new $225,000 filtration plant is now in operation. The building is of concrete, with red tile roof, and is artistic in design. The filtration or purification plant is located on the north side of the boulevard, immediately opposite the lower pumping station. It consists of six coke prefilters, 10 feet in depth and two-fifths of an acre in total area; a settling basin, divided into two units, with a total capacity of 500,000 gallons; six sand filters, with a total area of one acre; and a filtered water reservoir of 1,000,000 gallons capacity. All of the operations involved are controlled in the building shown in the accompanying illustration, where are contained the main valves and recording apparatus. At the rate of 75 million gallons per acre per day through the prefilters. and a 10 million gallon rate through the sand filters the areas provided have a capacity of a 10-million gallon daily output. Allowing for cleaning and for the possible desirability of a lower rate through the coke, the plant is believed to be ample for an average daily supply of 7,500,000 to 8,500,000 gallons, or-if the past growth of the population holds in the future-sufficient for the needs of the city until 1935.”
January 20, 1916: Municipal Journal article–Engineers’ Report on Water Supplies. “Watertown, N. Y.-The report of Hazen, Whipple & Fuller, the consulting engineers, who for several months past have been investigating available sources from which Watertown might secure its water supply has been presented to city officials. The report is an exhaustive one and is supplemented by maps of the available areas prepared under the direction of the engineers. Four possible sources aside from the one now used are considered in the report, and, while no recommendations are made, statistics of the cost of the works and cost of maintenance all of which are embodied in the report, show that the possible supply from the north branch of Sandy Creek is the most satisfactory and least expensive. The report shows that the proposed Pine Plains source would not furnish a sufficient supply of water from wells alone. While the city at the present time consumes approximately 6,000.000 gallons of water a day, the commissioners decided before the survey started that no supply would he considered satisfactory unless it would furnish at least 12.000,000 gallons per day. This would assure a supply that could be used without addition for many years to come.”
