I H R n. n Merritt BYU professor and summer consultant consultant con con- for the Provo based firm has determined that half of the clear water seepage could be eliminated by taking corrective methods lie He gave a rough estimate of that it will cost the city to correct the correctable problems Problems within the system are identified through the use of ofa a television system that is pulled through the sewer pipes Community Consultant COI worl workmen men first clean out put the pipes by utilizing a high powered spray hose that washed the to facilitate a better visual determination of the system A camera is then pulled through the cleaned out pipes thus enabling the workmen to inspect the interior of the system and identify problem spots spot AFTER VISUALLY seeing such problems in the line as breaks dislocated joints or bad lateral connection analysis can then determine the corrective method which will be utilized Dr Merritt mentioned replacement of the system grouting or the repairing of the lines as options for city of of- The cost cast of repairing the problems in the sewer system w will ill be included in the total cost of the upgrading of present facilities or construction of an entirely new system Whichever plan the council decides on it will be at least a year ear before movement in lu that direction begins according to City Manager Glade J.
