SOUTH BEND PUBLIC UTILITIES <br />224 North Main Street <br />P.O. Box 1714 <br />MICHAEL L. VANCE <br />Director of Utilities <br />Mrs. Beverlie Beck <br />President <br />Common Council <br />City of South Bend <br />Dear Mrs. Beck: <br />CITY of SOUTH BEND <br />ROGER O. PARENT, Mayor <br />COUNTY -CITY BUILDING SOUTH BEND, INDIANA 46601 <br />February 22, 1983 <br />219/284 -9322 <br />The ordinance enclosed will be filed for first reading of the <br />February 28, 1983 Council Meeting. If approved, the ordinance will <br />provide $52,500 in funding for the renovation of manhole structures. <br />In recent years the City through its Department of Sanitation has <br />seen an increasing number of manhole.collapses or failure through <br />structural fatigue. What I would propose through the use of these <br />funds is that the older brick manholes specifically those on South <br />Main from Sample south to Ewing to be renovated. The process <br />would involve, the internal cleaning of these units by our people, <br />the lining of them with a reinforcing material, and then the <br />spraying of a liquid concrete /cement known as gunite (trade name). <br />When the units have dried and set, you have a sealed structurally <br />sound liner that keeps infiltration to a minimum and adds strength <br />to the aged structure. This appears to have potential as an alter- <br />native to manhole replacement at the time of failure. <br />If you have additional questions, please feel free to contact <br />me. <br />Sincerely, <br />jj%�e V"-.— <br />Michael L. Vance <br />Director of Utilities <br />MLV /mtw <br />Enclosure <br />
