PUBLIC WORKS COMMITTEE TEAM 3-21-12 LMS
The cause of City Hall elevator problems was one of several topics discussed at the March 14 meeting of the cityís Public Works Team.
Team Chairman Fred Waidely told the Salmon City Council March 21 that the Otis Elevator company has isolated the problem to an elevator door sensor mechanism. The outdated sensor causes the doors to spontaneously close whether someone is in the way or not. The company determined that the solution is to install an entrance protective device priced at $3,085. Grant applications have been submitted and $300 from a Senior Citizens fundraiser will be contributed. The city will provide $1242 from its building maintenance fund.
Waidely said that after hearing details about construction of the new Ambulance Building on VanDreff Street, the team will make a recommendation to the City Council that utility hook-up fees be waived. The county proposed to dig the trench for a lateral hook-up and lay the sewer pipe. The city will provide the hot tap connection to the sewer line, run a tap for the water and connect the meter. The EMTís will be required to pay for the water meter which amounts to around $950.
Repairs to the sidewalk on the lower end of Fulton Street were discussed. City Administrator George Ambrose will proceed with the required engineering services.
City Public Works Supervisor Mickey Verbeck informed the Public Works Team that the City Hall roof above the Senior Center is leaking as well in other areas of the building. He and Ambrose will work on a contract proposal for repairs/replacement.
Ambrose reported on a draft technical memorandum from Keller and Associates concerning infiltration and inflow measurements from the Waste Water System. He said there is a significant reduction in flows since 2009 which is attributed to repairs and upgrades that have been made to several of the lines. It has also been determined that the inflow into the sewer main under the Salmon River is contributing 300,000 gallons a day to the water treatment plant. Ambrose said having to treat that amount of water per day is of course costing money and it is hoped that when the line under the river is relined the extra flow will be eliminated.
Waidely said Ambrose told the Public Works Team about a new media filter from WesTech which has a good track record and is less costly than other types of filters that have been researched and tested. The team recommended that the council consider the filter and the topic was placed on the councilís official agenda.
During the March 21 Council meeting the council approved money for a WWETCO Compressed Media FlexFilter pilot plant which will be brought to Salmon by the company and operated during the month of April. The test will take place during the month of high algae count. Cost of the pilot plant will be $7,000 and that cost would be rebated if the FlexFilter is purchased. If the filterís performance lives up to expectations, a smaller building would be required to house it and operating costs would be less than previously anticipated.
