The Proposed New Water-Works for Duluth.
The following estimate has been made by City Engineer Keating of Duluth, Minn., of the cost of constructing the proposed water supply system in three parts of the city which are at present without water service. His report reads as follows:
“The estimate herewith submitted provides for raising the water from Lake Superior and delivering it into reservoirs for the supply of the low and middle sections of the city, the high section to be supplied by special pumping machinery forcing the water directly into pipes without the intervention of a separate reservoir, the construction of which may be deferred until some future day when the necessity for it becomes more apparent than at present. No provision has been made for land damages or for the construction of the distribution system, as I understood from conversation with mover of resolution, that the laying of the distributing mains and pipes would form a separate undertaking which need not now be considered, beside which considerable time would be required to prepare the necessary plans, before even a rough estimate could be arrived at giving the probable cost of delivering the water through the various streets and avenues. It would have been more satisfactory if sufficient time could have been granted me to make a thorough investigation info the whole subject and to prepare plans upon which a reliable estimate might be based, as one of the first requisites, before estimating upon any work—with some degree of certainty—the quantities and character of the various materials that will be both encountered and employed during construction. Owing to the shortness of the time at my disposal, I have therefore been obliged to assume certain data which on closer examination and investigation may be found different from what is anticipated. I have, however, made liberal allowances and unless the information furnished me regarding local conditions and prices is considerably wide of the mark, I believe that the estimate is sufficient to cover all ordinary contingencies.
“ I may explain that the estimate has been prepared with the view of dividing the city into three separate water districts which may be termed the low, middle and high service supplies. The low service supply would embrace approximately all that district up to an elevation of about 200 feet above the lake : the middle service would embrace the district above the range of the low service supply up to 400 or 450 feet above the lake and the high service system would supply the higher portions of the city above the range of the middle service supply.
