W A Determination of the Cost of Delivering Lake Michigan water to the City of Grand Rapids, Michigan, Through Existing Supply System A Thesis Submitted to The Faculty of MICHIGAN STATE COLLEGE of AGRICULTURE AND APPLIED SCIENCE by Thomas B. Newberg w Candidate for the Degree of Bachelor of Science July 19h8 Purpose; To determine the average total cost per gallon of supplying the city water filtration plant at Grand Rapids, Michigan with water from.Lake Michigan through the supply system which has been in operation since August of l9h0. The fiscal year 1947 ( June 30, 1947 to July 1, 1948 ) will be used as the basis for calculations. Description; The accompanying Plan and Profile map of the portion of the‘water Supply System under consideration shows the main intake located at a point 6200 feet out from the lake shore. This intake consists of a 54 inch steel pipe elbow turned up and protected by a 36 foot square heavy timber crib. The top of the intake is approximately h2 feet below the.nean surface of the lake.‘water admitted by the intake flows through the 5A inch intake pipe to a wet well surrounding the lakeshore pumping station, entering the wet well at an elevation of 560.00 feet above M;S.L., which is 18 feet below the Lake Michigan surface elevation of 578.00 feet, MQS.L.. Two emergency intakes are located on the intake line between the main intake and the shoreline. The intake line is constructed of 5A inch steel and concrete pipe, anchored and supported by concrete saddles at 120 foot intervals, and connected at the joints by rubber gaskets and steel rings. 20331.5 The wet well consists of a cylindrical shell 6.5 feet wide, 70 feet in diameter and 42 feet in depth, the bottom elevation being 552.00 feet above MQS.L.. The 45 foot (inside diameter) cylinder which forms the inner wall of the wet well houses the lakeshore pumping station, the pump intake level being at 556.00 feet elevation. Normal depth of water in the wet well with no pumps operating is 26.00 feet, with a drawdown of approximately 11 feet during maximum pumping operation. In the lakeshore pumping station there are five vertical pumps, the pump floor being at elevation 560.00 feet M;S.L., and the motor floor being at the high water elevation of 584.00 feet MQS.L., 5 inch pump shafts are suspended from.bearings on the motor floor. The pumps are of the following ratings and operating heads; #1-- lA.M.G.D. 220 Foot Head #2- l7 M.G.D. 235 Foot Head #3- 21 MiG.D. 255 Foot Head #h- 25 M.G.D. 280 Foot Head #5- 31 M.G.D. 325 Foot Head Maximum capacity is obtained by operating #4 and #5 pumps simul- taneously. This combination supplies 52.7 M.G.D. to the filter plant at Grand Rapids, provided the booster station at Allendale is in operation. A supply of 33 MiG.D. is provided by operating the #5 pump only, with no boost required. Automatically operated cone valves are set between the pumps and the header pipe, which header feeds into the main transmission line. Valves open or close in approximately thirteen minutes to prevent water hammer. Surge valves are located at the junction of the header and the main transmission line. A venturi is located in the first fifty feet of the transmission line from which lines run to a control board inside the pump- ing station, indicating pressures and volumes of water being transmitted. Hourly readings are tabulated. From the lakeshore pumping station the water is transmitted through a A6 inch Lock Joint steel and reinforced concrete pipe along highway M950 right-of—way to a booster station located one-half mile west of Allendale, Michigan. During periods when more than 33 M.G.D. are being transmitted to the filter plant, the booster station is operated, the water being byhpassed from.the transmission line, through the booster pumps, and bank to the transmission line at increased pressure. The booster station pumps are of the following ratings and operating heads; #1 -- 11+ M.G.D. 200 Foot Head #2 -- 21 M.G.D. 210 Foot Head #3 - 25 M.G.D. 225 Foot Head #h -- 31 MiG.D. 235 Foot Head From the booster station the water flows under pressure through the transmission line Easterly along M550 to highway M9114, thence North along Mkllh to the highest point on the line, as indicated on the Profile map..This highest point is 168 feet above the lakeshore station pump level. Gravity flow then carries the water by the circuitous route shown on the accompanying map, around the Northwest section of the city of Grand Rapids, into the city at Richmond Park, and across Grand River to the city filtration plant located on Monroe Avenue and Sweet Street. Man holes and valves therein are located as shown on the accompanying Profile map. History; On may 12, 1938, the city commission of Grand Rapids, Mich- igan initiated a survey to determine the feasability of obtaining water from.Lake Michigan for city use in place of the then present Grand River source of supply. The main reason stated for the move was that during periods of high consumer use, the fire demand supply was dangerously low, and it was feared that with the inevitable growth of the city, the Grand River source would be insufficient within a period of a very few years. In June of 1938 the city commission entered into an agree- ment with the Federal Government, whereby a water supply system improvement including the procurement of water from.Lake Michigan would be financed fiftybfive percent by the City of Grand Rapids and forty-five percent by the Public works Administration of the United States. The city commission then floated a bond issue of $2,255,000.00 in $1,000.00 bonds at 2.82% interest, maturing as per the follow- ing schedule; Principal $70,000.00 70,000.00 70,000.00 80,000.00 80,000.00 85,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 90,000.00 eats 8-‘h4 8-!45 8446 8-'1+7 anus 841.9 8-150 Maturity Date 8-‘51 8-‘52 8-‘53 8451+ 8-!55 8-'56 8-‘57 8-‘58 8-‘59 8-‘60 8-'61 8-‘62 8-i63 8461. 8-‘65 8-‘66 8-'67 8-‘68 ~6- P.W.A. Project #1587-F included the construction of additional reservdirs and pipelines within the city of Grand Rapids which do not enter into the cost of delivering water from.Lake Mich- igan to the Grand Rapids filter plant. Wbrk on the Lake Michigan to Grand Rapids pipeline was begun in May of 1938 and completed in August of l9h0.
