Battle Creek Water System.
W. W. Brigden, superintendent and civil engineer of the water supply at Battle Creek, Mich., has recently issued the following information concerning the system: Source of supply, Goguac Lake, 360 acres area; water shed, 1 ½ square miles; maximum depth, 80 feet. Part of the year the lake is fed from Minges Brook; drainage area, 14 square miles. Two Blake compound, duplex condensing steam pumps, each 2,500,000 gallons daily capacity, and one Union Steam Pump Company crank and flywheel Corliss steam pump, 3,000,000 capacity. Pressure 65 to 85 pounds down town, 45 pounds at pumps. Average lift of pumps, 120 feet, including suction and friction. Standpipe, 75 feet by 18 feet, top 200 feet above business part of city. Bonded debt, $30,000; no other indebtedness. We pay all operating expenditures, interest and construction work ‘out of net earnings, and could pay the $30,000 bonds in 1911 if they were due. Balance in hands of city treasurer to credit of water fund, $30,648.04, so we practically owe nothing. We operated our waterworks for over twentyone years without purchasing a new pump, boiler or other similar part of the plant. We have made no extraordinary construction expenditure except $20,000 for diverting the Minges Brook into Goguac Lake for a larger supply, as contemplated before the works were built, and about $12,000 for a large number of experimental wells. Tn 1909-10 there were added a new 12-inch force main, inlet and suction pipes, extension to pumping station and a three million-gallon pump.
During 1910 the pumpage reached 762,000,000 gallons. Ninety-five per cent, of the services arc metered, and 57 per cent, of the water is metered. Meter rates, 6 to 13 cents per 1,000 gallons. Minimum annual rate, $3, except for large pipes, which are as follows: 8-inch, $100; flinch, $200; 4-inch, $100; 3-inch, $75; 2-inch, $50; 1inch. $35 : 1 ¼-inch, $15; 1-inch, $6. Sprinkler system pipes for lire protection, $25 per year and double regular meter rates for water used through sprinkler meter. Meters are sold at cost or rented at annual charge of 10 per cent, on cost, except %-incb meters rent for 10 cents and ¾-ineh for 12 cents per month. All new takers must put on meters, and all who change pipes or fixtures or add thereto. We began placing meters in time, did it gradually, and made it an object by giving low meter rates, so we had no real trouble. Our people approve of a meter system almost unanimously. Income from water rates, $49,194.48; income from rent of meters, $5,378.64; proper charge for use of 586 hydrants, $10, $23,440; proper charge for City Hall, engine houses, schools, water troughs, parks, flushing sewers, etc., $6,000: total, $84,013.12; operating expenses, $17.590.87; interest on total cost at 4 per cent., $19,877.16, $37,468.03; total. $46,545.09; estimated depreciation, 3 per cent, on total cost, $14,907.87; net gain by operating, $31,637.22.
The proposed plan for a new supply for Grand junction is to take the entire flow of Whitewater Creek at a cost of $250,000.
