lucityoJ Louisville COLORADO • SINCE 1878 CITY COUNCIL COMMUNICATION AGENDA ITEM 4B SUBJECT: RESOLUTION NO. 72, SERIES 2015 — A RESOLUTION APPROVING AN AGREEMENT WITH THE TOWN OF SUPERIOR FOR THE EMERGENCY POTABLE WATER INTERCONNECT DATE: OCTOBER 13, 2015 PRESENTED BY: KURT KOWAR, PUBLIC WORKS DEPARTMENT SUMMARY: Staff is recommending approval of an Intergovernmental Agreement with the Town of Superior outlining operational protocols for a new interconnect system between the Superior and Louisville potable water systems. In 2013 City of Louisville and Town of Superior staff discussed the concept of a potable water interconnect between the City and the Town to provide both municipalities with a redundant treated water supply. Doing so would: • Provide Superior redundancy for potable water treatment in the event of an emergency. • Improve Louisville redundancy for potable water treatment in the event of an emergency. • Provide extra capacity for Louisville potable water supply in future years when peak day demands in the summer may slightly exceed Louisville existing water treatment capacity. The interconnect investment was $300,000 versus $5 -10 million dollars for a full water treatment plant expansion. • Potentially provide for potable water supply of both communities during the winter from one water treatment plant. Currently each community runs their separate water treatment plants during the winter. Power costs and general wear tear on water treatment plants could be minimized in this scenario. In 2014, Louisville's City Manager and Town of Superior's Town Manager executed a letter of understanding for sharing design expenses associated with the interconnect. The attached Intergovernmental Agreement describes the construction, operation, maintenance, and improvement responsibilities between the two municipalities. The proposed interconnect would be Louisville's second potable water interconnect, with the first being with the City of Lafayette. The project would result in Superior's only emergency water supply.
