APRIL 6, 1998 SUBJECT: BACKGROUND: At the April 7, 1997 Council meeting, the Council authorized Bonestroo, Rosene, Anderlik, & Associates to provide the required professional engineering services for the completion of well #6, reconstruction of well house #3, and the associated water system improvements, which included SCADA (Supervisory Control And Data Acquisition) upgrading. The 1997 Capital Improvement Program (CIP) included the construction of well #6 and the reconstruction of well house #3 which is badly deteriorated. Wellhouse #3 currently houses well #3 and serves wells #3 & #4. When reconstructed, wellhouse #3 will serve wells #3, #4, and, upon completion, well #6. Reconstruction of wellhouse #3 eliminates the need for a well house for well #6 and does not complicate the subsequent construction of well #6. At the October 6, 1997 City Council meeting the Council approved going forward with the reconstruction of wellhouse #3 and the upgrading of the SCADA system prior to beginning construction of well #6. A copy of the agenda report for that meeting is included with this report. At the March 2, 1998 City Council Meeting the Council approved the plans and specifications and authorized the advertisement for bids for the Reconstruction of Wellhouse #3. A copy of the agenda report for that meeting is included with this report. DISCUSSION: Bids for Reconstruction of Wellhouse #3 were opened on Tuesday, March 31, 1998, and are tabulated as follows: 1620'@3~~reek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (612) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER FINANCIAL IMPACT: ALTERNATIVES: WH3AWARD.DOC I Contractor I En Comm Midwest, LLC. I Richmar Construction, Inc. I Municipal Builders, Inc. Total Bid $307,083.00 $326,760.00 $328,860.00 The Engineer's estimate for this project was $430,000. Favorable bids were received due to the time of year this project was let and the competitive bidding climate. Reconstruction of well house #3 will be required to be completed during the off season for sprinkling because it will require taking two of the City's three wells offline for the period of reconstruction. The current average daily demand for the City is easily handled by one well. We have arranged with the City of Savage to provide emergency back-up through the Boone Avenue interconnection. They have. sufficient storage capacity to supply both Cities for two days. In the worst case scenario of our single well going down during this time we are confident repairs can be accomplished within this timeframe. For construction to take place from mid-October to mid-December we need to award a contract at this meeting so equipment can be ordered and arrive in time for the mid-October start. Based on the favorable bids received it is the Staff and Consulting Engineer's recommendation to award the bid to En Comm Midwest, LLC., of Cambridge, Minnesota. This project is being funded through the Trunk Reserve fund. The Trunk Reserve Fund had a balance of $2,132,135.24 on March 1, 1998. There are three alternatives for the City Council to consider: 1. Approve Resolution 98-XX awarding the bid for project 97-03, Reconstruction of Wellhouse #3 in the amount of $307,083.00 to En Comm Midwest, LLC., of Cambridge, Minnesota. 2.

OCTOBER 6,1997 DATE: INTRODUCTION: The purpose of this Agenda item is to consider approval of reconstruction of well house #3 and replacement of the water SCADA (Supervisory Control And Data Acquisition) system prior to construction of well #6. This is a minor change from the schedule anticipated in the 1997-2001 CIP ..' (Capital Improvement Program) and is driven by the requirements that the Minnesota Department of Natural Resources has put on the City prior to permitting well #6. BACKGROUND: At the April 7, 1997 Council meeting, the Council authorized Bonestroo, Rosene, Anderlik, & Associates to provide the required professional engineering services for the completion of well #6, reconstruction of wellhouse #3, and the associated water system improvements, which included SCADA upgrading. The 1997 Capital Improvement Program (CIP) included the construction of well #6 and the reconstruction of well house #3 which is badly deteriorated. Wellhouse #3 currently houses well #3 and serves wells #3 & #4. When reconstructed, wellhouse #3 will serve wells #3, #4, and, upon completion, well #6. Reconstruction of wellhouse #3 eliminates the need for a wellhouse for well #6 and does not complicate the subsequent construction of well #6 DISCUSSION: The City has moved forward in the planning and design for well #6 and the reconstruction of wellhouse #3. Part of the well construction process requires us to get an appropriation. permit from the DNR. Getting the permit is challenging because of the Savage Fen, Boiling Springs, and Eagle Creek, which are all protected by state statute. The City's current wells draw groundwater from the Jordan aquifer. The DNR maintains that these environmental features are fed by the Jordan aquifer and municipal pumping of the Jordan adversely affects them. Therefore, it has been anticipated that well #6 will go down to the Mt. Simon-Hinckley aquifer which is much deeper, but also protected by state statute. 162~~reek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (612) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER --- ----.,. Since the April City Council meeting the Met Council established what has become known as the South West Metro Ground Water Work Group (SWMGWWG). The work group includes, but is not limited to, representatives from Met Council, Prior Lake, Savage, Shakopee, Burnsville, Lakeville, Scott County, DNR, and Minnesota Department of Health. This work group was established to look at the water supply issue for this region as it relates to expected growth and protecting environmental features. We have had ongoing discussions with the DNR regarding the appropriation permit. At this time they are not convinced that a new well is required immediately. They base this on the fact that our peak demand is a function of lawn sprinkling, and they feel we need to do some things to reduce this demand. Specifically, they would like us to consider: 1) An odd/even/partial day sprinkling ban; 2) Re-visit our rate structure to provide that those that use more water during the sprinkling season pay more; 3) Emphasize public education; 4) Get a better handle on :. unaccounted for use, i.e., meter City water usage, account for hydrant flushing, street sweeping. irrigation uses, etc. These requirements are a result of their interpretation of the state statute that protects the Mt. Simon-Hinckley aquifer which states in part, "The commisioner may not issue new water use permits...in a metropolitan county...unless the appropriation is for potable water use, there are no . feasible alternatives to this source, and a water conservation plan is incorporated with the permit." The DNR has indicated if we. address these items they will most likely grant the permit for a Mt. Simon-Hinckley well. They also want the City to commit to continue working with the ground water work group. Given the City's rate of growth we will probably need another well in the near future, it is highly advisable to continue working with this group. Due to the time involved with actually drilling well #6, the critical date is now May 1,1999, to have a well completed and on line for the 1999 peak season. Staff is formulating a new water conservation ordinance that will incorporate the things the DNR would like to see for Council consideration. The original plan for drilling the well and reconstructing wellhouse #3 anticipated letting two separate contracts, one for well drilling and development and the second for the reconstruction of wellhouse #3 and the SCADA system. The original plan would have had the contracts on a parallel track for completion at the same time. Due to the delay of well #6, this plan is no longer advisable. Wellhouse #3 currently serves wells WEIJJlSE3.DOC 3 and 4, but will be reconstructed to serve 3, 4 and 6. It is an old sheet metal building that has not aged gracefully due to the chemical environment. Further, the main control system for the city's water system is located in wellhouse #3 and the chemicals have corroded the electrical components to the point that they are no longer reliable. The plan. for reconstructing well house #3 will replace the control systems and put the main control for the water system at the Maintenance Center utilizing a new SCADA system. The building will be constructed with low maintenance corrosion resistant masonry and an architecture suitable for a residential neighborhood. Due to the condition of wellhouse #3, it is staffs recommendation that we proceed with reconstruction at this time including the SCADA system. We will have the engineer incorporate the addition of well #6 into the planning and construction. The current estimate for reconstruction of wellhouse #3 to serve wells 3, 4, and 6 is $430,000. Construction of well #6 is estimated at roughly $250,000, for a total project cost of $680,000. The cost for construction of .~ a wellhouse to serve a single well would be about $250,000. As mentioned, wellhouse #3 will be reconstructed to serve three wells. Because something must be done with wellhouse #3, it is much more cost effective to reconstruct it to serve three wells than to reconstruct it to serve the two current wells and construct a new wellhouse to serve the future well. In addition to these costs, replacing the SCADA system for the city water system is estimated to cost $162,000. This will replace the existing system that monitors each well/wellhouse, both water towers, the Wilds booster station; and will tie into the master control at the Maintenance Center. The 1997-2001 C.I.P. schedules water system improvements as follows: 1997: Construct Well #6, Reconstruct Wellhouse #3 1997: Relocate Water Master Control Panel to Maintenace Center 2001: Replace Water SCADA System /Install Sanitary Sewer SCADA System The proposed construction schedule is: 1997/98: Reconstruct Wellhouse #3 1998: Replace Water SCADA System 1998: Construct Well #6 2001: Install Sanitary Sewer SCADA System WElliISD.DOC $565,000 $ 35,000 $415.000 $1,015,000 $430,000 $162,000 $250,000 $253.000 $1,095,000 AL TERNA TIVES: RECOMMENDATION: ACTION REQUIRED: WELUlSEJ.DOC The $80,000 difference is a result of current detailed estimates for reconstruction of wellhouse #3 and the water SCADA system, a refined estimate for construction of well #6, and no current detailed estimate for installing a sanitary sewer SCADA system. . If approved, future C.l.P.'s will incorporate these changes. There are three altematives for the City Council to consider: 1. Approve reconstruction of wellhouse #3 and the replacement of the water SCADA system prior to construction of well #6. 2. Deny this item for a specific reason and provide staff with direction. 3. Table this item until some date in the future. Alternative No.1. . A (ion and ;econd to rove the recommended alternative. '. /1vt) Jv1f--, REVIEV /
