E., ity of Ramsey Leonard Linten, P. , i ty of Ramsey From: Paul Saffert, P.E. s Subject: Water Supply Projlects Update Ramsey, Minnesota Wells 7 and 8 Bids were received for the construction of Wells 7 & 8. E.H. Renner & Sons is the apparent low bidder and staff is recommending award on August 8, 2006. Bolton & Menk, Inc. is completing design of the ' well house located on the Fire Station Site and is seeking approval to Advertise for Bids. - The raw watermain between Well 8 and the well house is incomplete. Currently there is a gap of approximately 800 feet in the raw watermain route. It is necessary for the city to fill the gap to make Well 8 usable. Water Treatment Pilot Plant/River Intake The initial test well has been drilled in the Anoka County Park and has been pumping constantly for 3 weeks. The test well was drilled for the pilot plant testing of the riverbank water supply. Initial indications are the quantity of water might not be adequate by itself to supply the long -term needs of the City. A portion of the long -term water supply for Ramsey may need to come directly from the Mississippi River. Additional test wells will be drilled to verify the pumping capacity of the riverbank aquifer. Drilling will occur in the next week and analysis of the data will follow. Minnesota Department of Health (MDH) requires that if direct surface water is to be utilized, the pilot plant testing be run for a longer period (Fall- Spring) to include varying river water characteristics. Bolton & Menk, Inc. is continuing to work with MDH staff to outline the pilot plant requirements. Bolton & Menk has been working with three (3) manufacturers of membrane equipment for the pilot plant testing. There will be no extra costs from the pilot plant equipment suppliers for performing the longer duration of testing. Due to the longer pilot plant testing period and the additional pumping equipment required, three -phase power will be required for the pilot plant testing equipment. The estimated cost for providing three -phase power is $35,000. County Park staff will likely utilize the three -phase power in the future development of the park infrastructure. Bolton & Menk, Inc. is requesting to amend the pilot plant agreement to include an additional $35,000 to cover the cost of providing three -phase power to the site. City staff and Bolton & Menk have been communicating with the Anoka County Park staff on the potential of placing the long- term riverbank wells and river water intake pumping facilities on the park property. This would minimize any land acquisition requirements for the City and provide facilities that could be beneficial for Anoka County Park users. c. Bob Brown — Bolton & Menk, Inc.
