CR 91-184 Repairs Elmo Park Water Treatment FacilityAugust 14, 1991 Proposed Action. Y 0 A, /Y c P K \ 1 �6 , Council Report: 91-184 AUTHORIZATION TO PROCEED WITH REPAIRS OF THE ELMO PARK WATER TREATMENT FACILITY Staff recommends the following action "Move to authorize staff to proceed with the roof and wall repairs of the Elmo Park Water Treatment Facility in accordance with the attached reports from Ins-Dec Inc. at an estimated cost of $90,000.00". The adoption of the above motion would authorize staff to prepare the plans and specifications for this project, publish bid advertisements for this project,, and to use Water division funds as the funding mechanism for the project. Overview. Earlier this year the Water and Sewer Superintendent noticed water leaking through the roof at the Elmo Park Water Treatment Facility. The leaks gradually got worse which prompted staff to have Inspec Inc. look at the roof to determine the necessary repairs. As can be seen by the attached reports from Inspec, the roofing material is basically not worth repairing and Inspec is recommending complete replacement of the roof membrane. During Inspec-s review of the roofing material they noticed severe wall deterioration at this facility. Staff. subsequently instructed Inspec Inc. to study the walls and determine what repairs were necessary. Inspec recommendation for the walls included repair's that must be made ' in conjunction with the roof repairs, and other wall repairs that should be completed within two years.

The funding of this project with water revenue should not significantly impact the water reserve fund at this time. It was anticipated the these repairs would be necessary in the near future and they were therefore included in the CIP as a part of a complete filtration plant renovation in 1994 and 1995. The large repairs in 1994 and 1995 would have probably necessitated an increase in'water rates prior to commencing the projects in order to provide proper funding. The funding of these roof and wall repairs earlier than anticipated may create a need to review and possibly raise our water rates earlier than anticipated. o What is the timing of this project? If the project was approved as recommended the sequence of events, would be as follows: 1. Preparation of plans and specifications, advertisement of bids and award of contract. 2. Complete all roof repairs and wall repairs to the aeration tower this fall. 3. Install a vapor barrier on the inside walls.of the filtration plant this winter during low usage periods. The .vapor barrier must be installed during low humidity conditions and as such the plant must be completely shut down 4. Complete the remaining exterior wall repairs next spring. It's necessary that the inside vapor barrier be installed to eliminate moisture from traveling through the block work prior to completing the remaining wall repairs. o How would this project impact the city's water supply capabilities? As mentioned above, the city would have to completely shut down the filtration plant for approximately 2 -3 weeks this winter while the vapor barrier was being installed. The city's other filtration plant on County Road 3 unfortunately does not have enough capacity to meet the city's water demand even during low usage periods. Staff has therefore been in contact with Minnetonka to work out arrangements to open connections between the two cities water systems in order to meet Hopkins water demand for this period. e w . Council Report: 91 -184 Page 3 o Could this project be delayed? The leaks in the roof area are presently not affecting any of our filtration procedures. However, if leaks developed above our filtration areas and dripped into the treated water, the city would be forced to shut down the plant to prevent any contamination from occurring. Staff therefore feels that it is necessary to perform these repairs under a planned program instead of under emergency situations. Recommendation. Staff strongly feels that Council authorize this project as proposed in order that it may be completed under a planned approach instead of possibly under emergency situations. There will be furthermore significant cost savings by doing it as proposed instead of being at the mercy of a contractor during an emergency situation.
