#3 Improvements to Water Utility and apply for funding (File Res. Nos. 2009-600 & 2009-601) DEPARTMENT OF PUBLIC WORKS MEMORANDUM April 17, 2009 TO: City Council FROM: Daniel L. Lynch, PE, Utility Director SUBJECT: Action on Proposed Resolutions Authorizing the City Manager to Proceed with Improvements to the Water Utility and to Apply for a Wisconsin Safe Drinking Water Fund Loan and Authorizing Interfund Borrowing to Provide Interim Funding (File Resolution Nos. 2009-600 and 2009-601) Summary The City of Janesville has experienced residential growth to the northeast. This growth has increased the demand on the water distribution system resulting in unacceptable water pressure fluctuations. Independent engineering firms evaluating this problem have each concluded that additional water storage is presently needed on the City’s east side to support existing demands placed on the water distribution system. This additional storage will reduce the magnitude of the pressure drops on the City’s northeast side during high water demand situations such as those created when water is used to fight fires or when a major water main break occurs. Department Recommendation The Water Utility staff strongly support this project and encourage the City Council to adopt the proposed resolutions. Adoption of these resolutions does not create any additional financial obligation on the part of the City. This project will be before the Council at a future date to acquire a tower site and to authorize construction. Suggested Motion Move to adopt Resolution Numbers 2009-600 and 2009-601 authorizing the City’s application for a low interest loan and providing for interim financing for the proposed Water Utility improvements. City Manager Recommendation The City Manager concurs with the Utility Director’s recommendation based on the existing north zone pressure issues. I believe that supporting this project currently will provide the City the opportunity to seek funding assistance in the event the project continues to proceed forward. Analysis The North Pressure Zone serves about 30,000 people or almost fifty percent of the City’s 63,500 population. Normal water system pressure in the North Pressure Zone is about 60 PSI, but can vary from a low of 45 to over 100PSI. The North Pressure Zone can be divided into three general areas, which are: 1 Population Served (est.) West of the Rock River 5,900 Between the Rock River & the Interstate 17,900 North & East of the Interstate 6,200 Total 30,000 Distribution of water in the North Pressure Zone has been compromised on a number of different occasions resulting in either the complete loss of water system pressure or a major pressure drop in the portion of the North Pressure Zone north and east of the interstate. These events were accompanied by major water system pressure drops (up to 50 psi) in the remainder of this zone east of the Rock River and typically last about four hours. These extreme pressure drops are caused by: major main breaks (three- four in the past five years); failure of the pumping equipment supplying the zone (once in the past five years); or failure of the single river crossing connecting the west side of the zone to the east side (three times in the past five years). An example of the effect an extreme event has is shown on the attached map. As indicated on the map, during an extreme event such as a 16 inch main break, most homes north of highway 14 will experience water system pressure below 20 PSI. This pressure is below the minimum safe water pressure for residential or domestic use (35 PSI) and the minimum residual pressure for fire protection (20 PSI). This means that the water supply serving the residents northeast of the interstate may be compromised by groundwater, chemicals or other liquids being pulled into the distribution system creating a public health risk. In addition, in this part of the City the availability of water to fight fires is greatly reduced or eliminated. Less extreme, but still significant system-wide pressure drops (15 to 20 psi) occur more regularly during the warmer months when maximum hour water demands occur or during emergencies, such as fires, when large volumes of water are used in a short period of time. The North Pressure Zone problems are compounded by the following conditions: 1. East-west water main transmission capacity is limited. Large diameter mains exist on both the east and west sides of the North Pressure Zone; however, they are not connected. Even when the North Zone Reservoir is full, because of its location on the City’s far west end and inadequate east/west transmission capacity, the water cannot be conveyed quickly enough to the east side in high demand situations. 2. There is only a single crossing of the Rock River for the North Pressure Zone. While the river is only three to four hundred feet wide where the main crosses it, damage anywhere along a much larger segment of the main (about 7,000 feet) can take the crossing out of service. In the past five years, the single crossing has been taken out of service three times: twice because it was struck by contractors and once because of material failure. On one occasion both the river crossing and the reservoir were taken out of service. 2 The solution to these problems has been developed by AECOM, a nationally recognized engineering consulting firm that is also preparing the City’s update to the Water System Master Plan. The recommended solution is to construct a 1.5 million gallon water tower on the City’s northeast side and to construct a large diameter water main to connect the existing 24-inch mains on the City’s east and west sides. This project is estimated to cost approximately $7,150,000 and is being advanced at this time to take advantage of the increased federal stimulus funding recently made available. At this time the amount of federal funding available for this project is unknown, but that funding information will be known before the Council is asked to make a decision to proceed with this project. With storage on the west side of the river, well production on the east side, and significant residential populations on both sides, this is a critical situation. Having storage on both sides of the river and reinforcing the water mains between the east and west sides of the North Pressure Zone will greatly reduce the probability that unacceptable drops in distribution system water pressure will occur. The proposed Blackbridge water main and the new tower will help address this problem. cc: Eric Levitt, City Manager Jay Winzenz, Director of Administrative Services 3 4 RESOLUTION NO. 2009-600 A Resolution authorizing the City Manager to proceed with certain improvements to the Water Utility and to apply for a Wisconsin Safe Drinking Water Fund Loan WHEREAS, A new water tower and related transmission water mains must be constructed to stabilize the water distribution system on the City’s northeast side; and WHEREAS, the design of a project water tower was included in the 2007 Water Utility Budgets as a Capital Improvement Project; and WHEREAS, the construction of this project is expected to begin in December 2009; and WHEREAS, the City Council intends to fund this project by a combination of funding that includes: funds previously borrowed in 2007 and borrowing or receiving funds in 2009 in the form of a Wisconsin Department of Natural Resources Safe Drinking Water Loan Program low interest loan or grant as outlined in the following table: Project Funding Summary Funding Amount 2007 G.O.
