CITY OF SOUTH BEND South Bend, Indiana 46601 Jerry J. Miller Mayor Rollin E. Farrand, Sr., P. E. Director, Public Works Members of the Common Council County -City Building South Bend, Indiana Gentlemen: Reply To: Department of Public Works December 11, 1973 The Department of Public Works, through its Board of Wastewater Commissioners, received bids on December 3, 1973 for the following equipment. (1) 25,000 # G.V.W. truck for use in the grit removal building, and (3) 45,000 # G.V.W. trucks for use in hauling the lime sludge by- product from the expanded plant processes. Low bidder on the 25,000 # G.V.W. unit is McCarthy G.M.C. of South Bend at $5,892.50, and low bidder on the 45,000 # G.V.W. units is Jordan Motors, Inc. of Mishawaka at $11,676.25 each or a total bid of $35,028.75. We are asking for an appropriation from the Sewage Works Construction Fund for the initial purchase of these vehicles. We feel this is justified because the addition to the plant is the cause for the need of these units, and C.E. Williams depicts the use of these units in the construction drawings. The smaller unit which will be used in conjunction with the degritting and bar screen mechanism, will be used to haul rubble and large items which are filtered out of the inceptor sewer at this location. The degritting mechanism is design- ed in such a way that it is essential to have a truck there at all times. We realize that several questions were raised by the figures quoted in the South Bend Tribune article reference the Wastewater Plant. Let me first state that the 60 tons per day of lime sludge stated by the article is a figure with which we do not agree. We feel a more realistic figure is lime sludge in a dry solid form of 100 tons per day, and since a more realistic combination is 50% solids and 50% solution, you are talking about 200 tons per day. As a result of the chemical reaction which occurs in the phosphate removal process, 1 ton of lime chemical produces 2.5 tons of lime sludge.
