He said some areas of the line were not photographed due to excess water in the line, and ~hat these areas the City needs to go back and photograph. He sald the lower end of the main receives the most charges. Mr. Boeker stated 400,000 gallons of water from the Pleasant Street line was.in the ~ain at 1:00 a.m. when it was being tested, and that the Clty was 7n the pro- cess of determining the reason for this. Mr. Farr stated lt could possibly be a back flush from the pool at SWT. M7' O'Brien ~aid ~he line was mostly made of clay, which would have ~lttle de~erloratl~n, the main problem being joint separation due to.l~proper lnst~llatl~n. He said better methods were now available for ]Olnts. He sald durlng most of replacement or rehabilitation time to the line at leas~ one lane of traffic could remain open. Mr. Farr asked Mr. Boeker lf the estimates included patching or repaving Sessom, and Mr. Boeker stated patching. Ms. Kissler and Mr. Farr indicated it would be better to look at repaving this area, as patching would not hold up, and Mr. Boeker agreed it would be a better investment. Mayor Craddock asked. for a time frame, and Mr. O'Brien replied three months on the sewer Ilne would be a tight schedule. Mr. Coddington asked Mr. O'Brien for a time schedule from the time the contract is signed through completion of the entire line. Mr. O'Brien replied approximately two months for plans and specifications to send to the Health Department, approximately one week's review time by the Health Department, there would be time in- volved if we needed to go through the bidding process (Mr. Hankins interjected at this point to state there is a provision in State law which if the Council determined there was a finding of eminent threat to the River, which was considered a public calamity, then the City could dispense with the bidding process). Mr. O'Brien stated 30 to 40% of the line could be relieved by rerouting to the Sink Creek intercept- or. Sink Creek could take Hughson Heights, Tanglewood and Mimosa Cir- cle off this line. Mr.Brown asked if there was legal recourse if the line was improperly installed many years ago. Mr. Hankins~ated there would be a problem with the statute of limitations and whether or not the City properly inspected the line at the time of its completion. Mr. Boeker stated the line was different sizes in different areas, being 15",18" and 24", and Mr. O'Brien stated the City may need to oversize some of the areas of the line where the camera is indicating full capa- city. Mr. Brown asked if this was just a small portion of the problems the City may be experiencing with lines in the City and Messrs. Gonzalez and Boeker indicated that it was. Mr. Boeker indicated we were going to begin cleaning some lines and running camera tests in some of the major trunk lines. Mr. Brown asked if these lines were the main problem of pollution to the River, and Mr.Boeker replied that it is only one of the problems polluting the river and as an example, Mr. Boeker pointed out the inverted cyphon area of the golf course is another source of pollu- tion to the river, which is in the process of being corrected. Mr. Moore indicated pollution of the river should be our top priority to correct. Mr. Gonzalez stated it could run between $500,000-$800,000 to replace or rehabilitate the line. Mr. Brown stated he wanted the City to pursue assistance and involvement of SWT in correcting these problems. Mr. O'Brien indicated Freese and Nichols could prepare al- ternatives for the Council's consideration or replacement of the line. Mr. Farr indicated it may be premature to enter into contractual in- volvement with Freese and Nichols until such time as the additional study is completed that has been discussed. Mr. Gonzalez stated it may be better to obtain additional investigation but it would require addi- tional time and it may be better to contract to proceed on portion we know needs to be replaced. Mr. Coddington asked Mr. O'Brien if there were al- ternatives of better ways to install and/or replace the line, and Mr.
