Council might recall that late in 1993, Staff purchased a new dehumidifier for the Booster Plant. To save money, Staff is installing this system inhouse, but it will still require a mechanical company to plumb, charge and wire the system. Estimated expenditure is $2,000.00. Staff also briefed Council earlier about installing a flush out system in the backwash tank and install a foot valve on the reclaim pump at Water Treatment Plant #1. This equipment will reduce labor to clean out the sludge after any backwashes and greatly reduce the chance of contamination to the water supply by keeping.personnel out of the backwash tank. Staff estimates this equipment to cost $2,500.00. In 1988, Staff had recommended to consider new roofs and tuckpointing of all Treatment Plants and Pump Houses. In 1990, Assistant Engineer, Troy Gamble, and SEH, surveyed all buildings and recommended that repairs be considered as soon as possible. Since that time, new roofs were installed on the Booster Station and Pump House #2. The roofs and tuckpointing of Water Treatment Plants #2 and #3 were to be constructed when the revisions to the plant were bid. Currently, the contract for new roofs has been awarded at these plants, $16,800.00, however, all buildings must be tuckpointed. In many areas of these buildings, a vast majority of the bricks must be repaired. Staff is requesting quotes at this time. Since the buildings have decayed rapidly, Staff is expecting this repair to be extremely expensive. This repair may cost as much as $20,000.00-$50,000.00. While investigating these buildings, it was observed that a new roof should also be installed at Pump House #4. Projected cost will be $4,500.00. The following is a breakdown of project expenses. Fund balance a/o 1-4-94 is $292,000.00 Project Expense Roofs Treatment Plants #2 & #3 ($16,800.00) (Bid awarded) Tuckpointing & Doors (Treatment Plants #2 & #3 and Wells #2 & #4) ($50,000.00) Treatment Plant #1 - Program Change ($ 1,500.00) Dehumidifier - Booster Station ($ 2,000.00) Modify Reclaim Pump & Backwash- Tank Treatment Plant #1 ($ 2,500.00) Roof - Well #4 ($ 4,000.00) Treatment Plants #2 & #3 ($58,000.00 ) (Balance due) Total funds remaining $157,200.00 Staff recommends that Council authorize Staff to proceed with these projects funded through the Water Bond Fund. Staff is researching additional areas where improvements, can or should be made, throughout the system. A couple possibilities would be to install a new electric motor to Well #2 (currently it is propane powered) and purchase a generator to provide.emergency.power. This motor is over 20 years old and has been rebuilt once and requires frequent maintenance. During an 8 hour run the engine uses 6-8 quarts of oil and 3-5 gallons of water. Another project possibility is the installation of variable speed pump controls at pumping stations. This modification can decrease pump wear, decrease electrical costs and constantly maintain system pressure and volume. This is something that must be addressed when the City's storage facilities require inspection or maintenance. NSP also offers rebates with this type of update. Staff will continue to evaluate these particular issues and more, and return to Council with recommendations.
