Specific other experience related to this project will be described later. Based on our knowledge and our current understanding of the problem, we have identified several potential solutions. In lieu of preparing a full blown qualifications package, we have decided to present a series of steps, starting with the least costly, to be implemented directly by City staff, to mitigate this problem. We would be pleased to assist with this implementation. Project Understanding The City of Elgin has been experiencing water hammer in the eight-inch lime residue transmission main that extends approximately five miles from the Riverside Water Treatment Plant to the South McLean Lagoon Site. The plant, the transmission main, and the lagoons were originally designed and later modified by Black & Veatch, starting in the early 1980's and continuing to the recently completed plant expansion in 1999. Therefore, we are intimately familiar with the facilities and with their operation. In recent years, the City has received complaints of water hammer associated with this transmission main from several of the residents located along the pipeline alignment. In fact, the recently completed plant expansion increased the amount of lime residue thereby increasing the pumping frequency through the transmission main. The recently designed second lime residue pump station was fitted with slow opening and closing valves to minimize any surges caused by pump start-up and shut-down. The existing lime residue pump station was also modified to be identical with the new pump station. On January 25, Black & Veatch staff met with City of Elgin staff to view the existing drawings, inspect the newly installed valves, pumps, and pumping station, and discuss the operational activities related to the water hammer occurrences. To date, staff has been unable to correlate pump sequencing with the water hammer occurrences. Detection of water hammer has been physically noticed by staff at one specific location along the pipeline route, although it is very difficult to determine exact plant operations which may be causing the water hammer. The water hammer is noticeable at a location approximately two miles downstream from the water treatment plant near Demond and Aldine streets. This location has two ninety-degree bends in the transmission main, approximately 200 feet apart directly adjacent to the location of the resident who has noticed the water hammer. The original force main, or lime transmission main, was designed and constructed in the early 1980s. The pipeline begins at the Riverside Water Treatment Plant, is routed west towards Route 31, crosses Route 31 continuing in a generally southerly and westerly direction, rising from the treatment plant roughly at Elevation 770 to a high point at approximately Elevation 845. The pipeline then continues to the South McLean Lagoons terminating in the lagoons at Elevation 811. The pipeline was designed to have a minimum depth of 5-1/2 feet and the profile indicates that the pipeline raises and lowers with river crossings, road crossings, and terrain changes. Air release valve structures were installed as part of the original design. Sometime in the early 1990s, some of the existing fittings in the release valve structures experienced corrosion due to the lime, and fittings were replaced by City staff City staff periodically visits each of the release valve structures, and bleeds air and some small amounts of lime residue as appropriate. 2.0 PROJECT APPROACH 2.1 Method of Analysis City of Elgin has requested a description of the consultant's method of analysis and projected time frames to perform the work described herein. Based on our review and understanding of the water hammer situation, we believe that a sequential approach to solving this problem would be most beneficial to the City. This approach will expedite the solution of the problem, minimizing any potential long-term effect that continued water hammer may have on the life of the transmission main, and also minimizes the City's cost outlay. Based on our preliminary evaluation and investigation to this point, we believe we understand the source of the water hammer, and have several suggestions to mitigate this situation. We believe that the cause of the water hammer is due to water column separation in the force main near the high point in the main. Since the plant output has increased with a corresponding increase in lime residue, the water hammer frequency has probably increased in recent years. Work Tasks Black and Veatch has developed the following work tasks to be performed in a stepwise fashion, in an effort to immediately reduce the severity and impact of water hammer on the transmission main. Each step is to be taken sequentially. Step 1 -Installation of Air Release/Vacuum Release Valves We believe that the installation of air and vacuum release valves at the appropriate locations would either eliminate or reduce the severity of water hammer caused by water column separation. We would work with City staff to inspect all of the existing air relief valve structures, perform investigation of the pipeline profile and rough hydraulics, and recommend location or locations for immediate installation of air and vacuum release valves. Step 2 -Valve Operators and Sequencing Presuming that the action taken in Step 1 does not adequately eliminate water hammer, or, in the event that the installation of multiple air and vacuum release valves is excessively costly, the second step would be the installation of controls and electrically operated valves, or installation of operators on existing valves, at the McLean Lagoon site. These valves would work in conjunction with the slow opening and closing valves recently installed in the lime residue pump stations. The operation of these valves would coincide with the pump operation such that the transmission main would remain completely full of liquid, eliminating the water column separation phenomenon. Step 3 -Additional Hydraulic Analysis and Field Testing. The third step would be to perform detailed computer hydraulic analysis of the transmission main, pump stations, and all of the related systems. This could involve extensive gathering of field data, installation of pressure and vacuum and recording devices, and extensive fieldwork. This level of effort would only be required if the solutions proposed in steps one and two proved inadequate to eliminate the water hammer. Step 4 - Complex Action. Following the analysis in step three, review of any residual water hammer may result in the construction of additional measures or devices to mitigate the water hammer situation. These might include surge tanks, surge suppression valves, and additional control or surge valves. 2.2 SCHEDULE The request for proposal indicated a three-month schedule for completion of the work. We would propose that completion of the first step of the project would occur in less than four weeks, depending on availability of City staff for completion of the inspection of the air release structures. Air and vacuum release valves could be purchased directly by the City and installed by City staff. If current workload is such that this option is not available, a construction package for bidding could be prepared. Our assumption is that City staff would be available to install any recommended devices in Step 1. Each additional step would take place over a period of two to four weeks following the completion of the previous step and authorization to proceed to the next step. 3.0 EXPERIENCE As a leader in the planning and design of water treatment plants, pumping stations, and pipelines, Black & Veatch has acquired a great deal of experience in all aspects of water and other fluid transmission. Hydraulic transient, or surge analysis, is a specialized area of hydraulics, primarily related to long pipelines or pipelines with substantial changes in elevation. B&V has been retained by a number of clients to specifically analyze an existing surge or hydraulic problem, such as this project. We have selected several recent projects that are similar in nature to your project, which are described below. For additional experience, please refer to the resumes of the project team members. City of Highland Park, IL. Water Transmission Main Repair Consultation. Black & Veatch was retained to investigate the repair of an 1880's cast iron water transmission main. The 20-inch main, operating at a pressure of approximately 110 psig, had previously undergone repairs at several leaking joints, prior to the failure at a 20-inch elbow. The water transmission system was subsequently shut down. Black & Veatch visited the site, interviewed operating staff, reviewed the high service pump operating records, analyzed the potential for hydraulic surges and developed scenarios of the events that ultimately led to the failure. We also recommended a repair procedure to return the transmission to active service, which was successfully performed. Recommendations for improving the long-term reliability of the transmission main system were also provided, particularly as related to the older portions of the system. Reference: Highland Park, Illinois Mr. Perry Walcott, P.E. Deputy Director of Public Works (847) 926-1145 Johnson County Unified Wastewater Districts, Kansas A transient analysis was conducted on the Turkey Creek Pumping Station after a series of valve failures flooded the pumping station. The pumping station pumps approximately 30 mgd of wastewater to the treatment plant. Using a computer based model it was determined that the cause of the valve failures was a result of the operating speed of the pump discharge valves. The actuators on the discharge valves were replaced with slow closing valves and this solved the problem. Another transient analysis was conducted on the Belinder Pumping Station. This pumping station pumps approximately 10 mgd through approximately three miles of force main that had several high points and no air release valves. The surge study was conducted to resolve the causes of surges which resulted in pipe movement within the pumping station. Using a computer based model it was determined that the cause of the pipe movement was surges due to water column separations at the high points in the pipeline combined with fast closing valves on the pumping units. A surge relief valve was installed in the pumping station to relieve the surge pressures, protecting the pumping station. Reference: Johnson County, Kansas Mr. John Metzler, P.E. Chief Engineer (913) 338-1300 Lawrence,Kansas A transient analysis was conducted on the Wakarusa Pumping Station. This pumping station pumps approximately 15 mgd from two pumping facilities through two parallel mains. The pumping station has had a history of shaft breakages on the pumping units. The surge study was conducted as part of improvements to the pumping station. Using a computer based model it was determined that the system had potentials for water column separations as a result of valve failure and recommended replacing slow closing check valves with swing style check valves.

Parker, City Manager SUBJECT: Engineering Agreement for Lime Residue Transmission Main Water Hammer PURPOSE The purpose of this memorandum is to seek authorization from the Mayor and members of the City Council to enter into an engineering agreement for design services related to the Lime Residue Transmission Main Water Hammer concerns. BACKGROUND The City of Elgin Water Department has been experiencing a water hammer effect in the eight-inch ductile iron lime residue transmission main that extends approximately five miles from the Riverside Water Treatment Plant to the South McLean Lagoon Facility. Water hammer is the term applied to the vibration in a piping system created when flow is started or stopped. The same situation can occur in the home when a faucet is slammed shut and the pipes rattle . In recent years, the City has received complaints of water hammer associated with this transmission main from several of the residents located along the pipeline . The water hammer has been physically noticed by the staff at one specific location approximately two miles downstream from the Riverside Water Treatment plant near Demmond and Aldine Avenues . This situation can also lead to breaks in the pipe line . Based on the City' s procurement ordinance, the Water Department requested proposals for services from eleven (11) different engineering firms . Attachment B identifies six firms that returned formal proposals with price quotes separately submitted. The six proposals were individually ranked by a selection team. The engineering firm of Black & Veatch (B&V) and Consoer Townsend Envirodyne Engineers, Inc (CTE) were selected the best qualified based on the evaluation factors, after which proposal fees were opened for these two firms. B&V' s proposal fee is $9, 500 , and CTE' s fee is $9, 750 . F _ft teb.- Engineering Agreement with Black & Veatch March 8 , 2000 Page 2 The proposed agreement is to provide engineering services in connection with the lime residue transmission main water hammer problem.
