been made in this regard. In fact, Mr. Comstock said there had been no definite evidence presented to justify such an action. He said that while replacing the line from Ruzel.le to Coolidge was part of the rebuilding project for 29th, the .Line from Coolidge to Stinson at a cost of $8,600.00 was not proposed to be replaced and if it were done so would cosi: $17,200..00 fok the 10 inch line. If the size of sewer line were increased for the entire project with a 12 inch line, the cost would be $21,250.00 and if a 15 inch line were used would be $29,500.00. Since there is no eviden- ce to show where any of these replacements would correct the backup problems which had been experienced along 29th last year such an action might later be criticized as an unnecessary expenditure. Mr. James Datta, a member of the Sewer Study Committee, said the committee had recommended the replacement of the entire line be- cause they were afraid the street would have to be torn up later if it should be proved that the size of the line was insufficient:. Mr. Dulgar said that even if the line should have to be replaced there would be other methods of doing so without tearing up the street. He also disagreed that the flooding experienced by resi- dents was all a backup of the sanitary sewer lines because of the clearness of the water he had seen in many basements. In discussing the short range solutions suggested by the Committee, the Engineer said that Minneapolis would be able to handle some of the City's overflow in an emergency or a permanent arrangement could be made with them but Roseville had told him they could only handle the normal flow and the sewer line to the arsenal was not a viable solution because the line was owned by the federal government who had refused to let any community use it in the past. Mr. Comstock commended the committee for their fine job on the report which he felt would be very helpful in assessing the City's sewer system for improvements. He told of an independent group of engineers who specialize in sewer system evaluations who the City might employ to make a smoke analysis of the sewer system at a cost of between $20,000.00 to $30,000.00 saying they might r:ieet the requirements of the committee's recommendation for such an analysis. He said that the committee's premise that the difficulties ex- perienced by some homeowners with backup water last spring should be considered a city-wide problem for city-wide solution seemed to call for a political rather than an engineering decision but said there might be some conflict with the Comprehensive Report pre- pared for the Metro Waste Commission which doesn't allow for tie diversion of residential drain tile through the sanitary system for treatment. He also felt that the committee should not have been influenced by the proposed EPA program guide u-hich had never bee;: accepted by EPA and had never been intended for publication. The Council felt that without concrete evidence that a larger sewer line would solve the backup problems, there could be no justification for replacing the line from Coolidge to Stinson but it was agreed that if such evidence should be presented before she street is replaced their decision could be reversed by change order.
