Special City Council Meeting September 19, 2002 Page 4 account for sidewalks, curbs, street and alley repair. Mr. Campbell said they were obligated to maintain good roads to their plant and to the master lift station. They also have concrete work that they do around the plant. It may not be a curb, but it will be like a curb where you knock-off something on one of the basins and have to do concrete repair. Mr. Campbell explained the $85,000 in the filter beds and valves account for the Water Production Department. He said that amount is to replace the effluent valve controllers on ten valves on the filters. Mr. Campbell said the new rules and regulations require that all of the filters be monitored continuously for the quality of the water output. If you surge the filters, then that water quality can go up and spike the controls that are on the filters, which were put on there eight years ago when the plant was modified. They are wearing out and they are going to upgrade them to better controls. Councilman McCarthy questioned the sidewalks, curbs, street and alley repair account again and Mr. Campbell advised that the street and alley repair is basically for materials that are put on the roads. After discussion, the City Council agreed by a show of hands to cut $6,000.00 from this account. //~Councilman Plata questioned the Account for Sludge Removal at the Water ~ Treatment Plant. Mr. Campbell said two old settlement basins from the Maxey Water Plant were used when the sludge handling facility was put in. Workers cannot get the sludge out fast enough. Mr. Campbell said he wanted to put automatic sludge handling equipment in the bottom of those basins. This will scrape the sludge and keep it mixed up so it can be sprayed on the field. He said there is a new rule called the recycle rule. The water that goes around to backwash the filters goes to a sump and it is pumped back for the sludge to be removed out of it. Then the water is decanted over and goes back to the head of the plant for treatment. If you cannot take the sludge out of the pit efficiently then the water that comes back is a bad quality and they have to shut down the recycle system and dump it into the creek. If you dump into the creek, the water has to meet a certain quality. The city does not have the facility to treat water that goes to the creek so they have to make sure that they recycle all of the water.
