HomeMy WebLinkAboutSS5 - Water Master Plan• CITY OF NEWPORT BEACH CITY COUNCIL STAFF REPORT Agenda Item No. SS5 September 8, 2009 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: Public Works Department Michael J. Sinacori, P.E. 949 - 644 -3342 or Msinacod @newportbeachca.gov SUBJECT: WATER MASTER PLAN —EXECUTIVE SUMMARY AND UPDATED RECOMMENDED CAPITAL IMPROVEMENT PROGRAM Recommendation: Receive and File Update to Water Master Plan and provide any comments or direction to staff related to implementation of the recommended improvements as presented. History: In November 1996, the City entered into a contract with Boyle Engineering Corporation for the development of a comprehensive Water Master Plan (WMP). A Master Plan updates • water demand projections, analyzes supply and storage capacities, models water transmission, distribution and fire flow needs and identifies water system improvements and /or replacement of the aging facilities. Though the City has a moderate sized system, it includes the operation of five pump stations, 15 major pressure reducing stations, seven connections to the Metropolitan Water District regional system, four wells, and three reservoirs, one of which has a floating cover. The initial Water Master Plan effort was completed in 1999 and identified over $50 million of improvements that were planned to be constructed over the next 20 years (by 2020). An Executive Summary from this 1999 Master Plan is attached. In combination with this 1999 Water Master Plan effort, the City was also actively working on major water improvements associated with the Groundwater Development Project (GDP) during that same time period with expenditures close to $25 million. Because of the large expenditures, including a $15 million bond issue for portions of the GDP, the recommended Master Plan did not contemplate completing all the recommended pipeline replacement improvements within the 20 year period. These additional pipeline replacements would have to be completed after 2020 and beyond the initial $50 million program (1998 dollars). Since the Water Master Plan was completed in 1999, approximately $3.3 million per year have been approved to complete water projects identified in that plan. In order to coordinate WMP projects and funding with other street improvements or utility assessment is district projects, staff has been forced to deviate from the Master Plan's proposed schedule since around 2001. In addition, cost estimates prepared in the Master Plan Water System Master Plan — Executive Summary and Updated Capital Improvement Program September 8, 2009 Page 2 proved to be approximately 20% lower than the actual cost realized to build the projects, • mainly as a result of the strong economy and corresponding escalation in labor and material prices. In addition, surface restoration costs were higher than anticipated. Discussion: Staff contracted with Civiltec Engineering in March 2008 to update the City's Water Master Plan. This effort included updating the hydraulic system model to include improvements completed since 1999, running the model to verify remaining or new facility improvements to ensure fire flow requirements are met; and reprioritizing projects to align with replacement needs as well as other Capital Improvement Programs such as street rehabilitations and proposed utility assessment districts. Project cost estimates were reviewed and updated and a new funding schedule was developed. The update was completed and submitted to the City in December 2008. Staff has since been working with Red Oak Consulting to incorporate master plan project cost needs into the pending water rate study, which included a review of all anticipated improvements required for the water system that were not funded in the 1999 WMP. The updated 30 year Master Plan identifies $88 million in improvements (2008 dollars), including replacement of older pipelines that are beyond their useful life. Several major City water pipelines that are still in service today date back to the 1920's. The updated Master Plan indicates a continued need of approximately $3.5 million in funding per year over the next ten years. The remaining 20 years may require funding • over $6 million per year to complete the identified projects. Some of the major projects in the next five years are centered on proposed assessment districts. In addition, old water mains on Balboa Island are slated for replacement to improve reliability and fire protection. In the latter 20 years of the revised plan, more projects focus on water system reliability by replacement of larger and older pipelines throughout the system. For example, the three main supply lines to the peninsula are at least 50 years old with one dating back to 1936. Funding Availability: Two subsidiary Water Funds are being maintained to segregate the resources available to fund master improvement plan activities separate and apart from water operations. This accounting measure helps segregate those resources that are dedicated solely for the purpose of maintaining critical water distribution systems from those that are available to fund water operations. Previous water financial plans considered a minimum annual capital funding of 10% of annual budgeted operating expenditures. The proposed master improvement plan would require funding closer to a 20% level. In order to accommodate the master plan as recommended, the water rates adjustments, currently being considered, contemplates a $3.5 million dollar annual contribution (escalated at 3.5% per year) to the water capital fund dedicated specifically for Water Master Plan improvement projects. This funding plan represents approximately 20% of overall operating expenditures as budgeted in fiscal year 2009 -10. Debt funding of this program may need to be periodically considered to provide • the cash flow necessary during peak construction periods. Water System Master Plan — Executive Summary and Updated Capital Improvement Program September S, 2009 Page 3 • Staff is recommending that the WMP be updated every ten years to review accomplishments, expenditures and projected needs and make any necessary adjustments to the program, which could include deferral of projects, bond issuance or increased contributions to maintain the program.

The study was undertaken to enable the City to plan, fund and prioritize future capital improvements by: 0 • Updating and calibrating the City's water system model using the EPANET model and data handling techniques compatible with the City's GIS system. Note that the City has recently added HZONET graphical interface to the EPANET model.. • • Evaluating the ability to serve present and future water demands under peak hour and various fire flow conditions using either City wellfield or imported water sources. • Identifying and integrating water system improvements for hydraulic capacity, system reliability, operations enhancement, and replacement of aging facilities such as piping. An appurtenant effort is development of a financial plan to enable the City to establish appropriate rates /fee structures to fund the necessary water and sewer system improvements. The financial plan is a separate document. Transmission and Distribution System Analysis Piping The City's water distribution system provides service for an approximate 13.5 square mile area including the future potential annexation of the Banning Tract. A total of approximately 600 acres • OCN03fiDU-0O gWNB MP EXSCZ f d= Es -t 93OWLE • of the City is served by the bordering agencies of Irvine Ranch Water District and Mesa Consolidated Water District (see Figure 1 -1). The water distribution system is divided into five major pressure zones, which are further divided into 17 minor pressure zones, serving elevations from sea level up to elevation 725 feet. The system is comprised of about 150 miles of water lines. Model Analysis: The updated water system model includes over 1,000 pipes, totaling about 150 miles in length, as well as 3 reservoirs, 4 pump stations and 36 pressure reducing valves. System piping size ranges from 4 inches to 48 inches in diameter, with the majority of the piping in the 8- to 12 -inch diameter range. Variations of the interior smoothness for unlined steel and cast -iron piping were accounted for based upon the age of the piping. The hydraulic network model was developed to analyze the system's ability to meet demands under specific conditions. The model was calibrated to simulate conditions measured in the field during May and June 1997, and was successful within less than 10% variation at all test points (see Section 5). Deficiencies in the system were determined based upon peak hour and maximum day plus fire flow conditions with projected ultimate demands. Based on a study of the City's land use plan and current and future large water users, the current average daily demand rate of 11,100 gpm is expected to show a modest increase to just over 12,200 gpm at ultimate development within the next 10 to 15 years. City staff identified 25 points and flows deemed critical for fire flow service, which were simulated via eight fire flow scenarios. Transmission and Distribution System Deficiencies: Based on the analysis, several hydraulic deficiencies were noted and improvements identified to remedy those requiring attention. Figure 7 -1 shows the location for each hydraulic system improvement recommendation with an accompanying numbered tag that corresponds to the items in Table 7 -1 and Table 7 -2, Part A and Part B (Distribution) projects. Table 7 -1 gives descriptions, justifications, modeling comments and estimated construction and capital project costs for each improvement in 1998 dollars. Table 7 -2 summarizes capital costs projected to the time of construction. These improvements remedy only those deficiencies of the peak hour, summer maximum day plus fire flow, and ultimate demand conditions GCS 03e00mia WBMP EaecSu .A c ES -2 13OWLE for the backbone water system identified for modeling by the City. • During the modeling process, areas in the water system that were deficient in meeting fire flow demands were noted. Transmission System Reliability Projects: The Part A projects mainly improve reliability in the distribution system, while the Part B projects address specific distribution system deficiencies. Project Al improves the transmission of Big Canyon Reservoir water to the Corona Del Mar area. Instead of routing water through distant transmission mains in San Joaquin Hills, Jamboree, and East Coast Highway, Big Canyon water is served directly to the southern tip of the city through a proposed 24 -inch main in Marguerite. As a result, this improvement will help to boost system pressure in the Corona Del Mar area during peak hour. Based upon an internal review of system reliability, the City has also determined that the Irvine Avenue improvement should be extended south from Santiago Road to Dover Drive in 24 -inch diameter as well as along Dover Drive to Westcliff Drive. Should the pipe bridges along PCH fail during a seismic event, water from the 16i° Street Pump Station will still be able to reach the eastern end of the system by rerouting water around Newport Bay along Irvine Avenue. This • review also resulted in the recommendation for a further extension of 12 -inch piping along Irvine Avenue from Dover Drive to Sherington. These improvements will improve the reliability of the backbone system linking the coastal portion of Zone 2 with the portion north of Dover Drive. Another Part A project related to water supply and delivery is the recommended construction of two new wells and appurtenant facilities. This project is estimated to be implemented in years 2012 and 2013. Part A and B projects have an estimated capital cost of $10,044,000 in 1998 dollars, which includes two future wells and connecting pipeline for about $2.8 million. Pipeline Replacement Program: City staff has developed a 50 -year pipeline replacement program for cast iron and steel piping built in the 1920s, `30s and `40s, and plans to replace approximately 88,000 linear feet of these aging mains through 2020. New piping diameters will match that of the old pipe, except where the old pipe was less than 8- inches in diameter, in which case 8 -inch piping is to be provided. Table 7 -2, Part C "Programmed Pipeline Replacements ". summarizes project locations, costs and proposed year of construction for these • oc.No3400.ovq-rN8WMPE sS,Aw ES -3 130VLE • facilities through 2020. The Appendix provides tables summarizing the exact street location of each project and lengths of construction therein. Part C projects total $23,191,000 (1998 dollars) through 2020. (See Exhibit B in jacket insert of this report.) Corrosion Assessment of Water Supply Sources As part of this Water Master Plan effort, an assessment was made by McGuire Environmental Consultants, Inc., of the implications of introducing a new source of water into the system. This was done in advance of startup of the City's new wellfield. A corrosion indices model was employed to compute indices for the imported water, groundwater, and blended water sources. All water problems and degradation of cement -based materials were also analyzed. The study concludes that the differences in water quality between the primary supply and blended groundwater are not expected to accelerate degradation of cement -based materials or ferrous in the City's system. The final report is contained in the Appendix. Reservoir Storage • The City is in a unique position in terms of storage, having within its service area a large open storage reservoir, Big Canyon Reservoir, at nearly 600 acre feet capacity or approximately 196 million gallons. For water quality protection, the City intends to install a floating (hypalon) cover early in its capital improvement program. • Total storage capacity (assuming Big Canyon Reservoir is at its average operating level and that San Juaoquin Reservoir is not available) is 102.3 MG. Of this storage, the City reserves a regulatory storage volume equivalent to about 25 percent of the maximum day demand (8 MG), plus 3.7 million gallons fire storage for a total of 11.7 MG. The City thus has approximately 90 MG of storage which can be considered emergency storage. Under the ultimate average day demand of 17.7 mgd, this represents 5.2 days of storage, which is more than the 1 to 3 days' volume typically found in Southern California water agencies. Note that the available volume could nearly be doubled if the Big Canyon Reservoir operating water surface elevation were raised by 14 feet. The City normally operates the reservoir at no greater than 286 feet elevation, but once a cover is installed, the emergency reserve will be increased. This indicates that the City has adequate storage, due to Big Canyon Reservoir. However, the ability oc.rrossaomrq.MHe P E..Sum_dX ES-4 00VLE to pump water from Big Canyon Reservoir to higher zones must be • maintained at all times, which is the subject of upgrade recommendations in the following sections. The City intends to implement nearly $5 million in upgrades for the Big Canyon Reservoir including a floating cover and disinfection system modifications, to be constructed over the next 4 years. The City has also identified the need for $1,470,000 in miscellaneous reservoir improvements. through 2020. Refer to Table 7 -2, Part F for the schedule and costs of these items. Pump Stations/Zone Transfer Capacity The analysis in (Chapter 6) of the City's ability to reliably transfer water to the higher pressure Zones 3, 4 and 5, concludes that the Zone 3 booster pumping station requires replacement of one existing 150 horsepower pump (2,700 gpm) and motor with a 300 horsepower pump (5,600 gpm) and motor, along with an additional 300 horsepower pump and motor. This would also require an upgrade of the electrical service for that pumping station. The analysis also concludes that the City's plan to install emergency • power generation capability for the Zone 3 Booster Pumping Station should be pursued, along with purchase of a portable engine generator set for emergency use at the Zone 5 booster pumping station. Zone 4 has an existing 1,500 gpm gas driven pump. It is fiuther concluded that energy savings warrant installation of VFDs at the Booster Pump Station to Zone 3, and at the Zone 5 Booster Pump Station. The above improvements are estimated to cost approximately $769,000 and all but the Zone 5 VFD are recommended for implementation within the next two years. The City has further identified $1,950,000 in overall maintenance upgrades for its pumping facilities through 2020 (in 1998 dollars). Refer to Table 7 -2, Part D, for the individual schedule and costs for these items. Variable Speed Pumping Currently, the City's booster pumping stations maintain constant discharge pressures by utilizing the pump control valves in a pressure reducing mode, thereby wasting pump head and electrical energy. An oc-NOS 600-WgWINB nr EKecs=.dm ES -5 BOYLE • analysis of installing variable frequency drive equipment to reduce energy use indicates that approximately $45,000, could be saved annually at Booster Pumping Station 3, for a capital cost of $85,000. The investment would pay back in 2 years. For Booster Pumping Station 5, the comparable annual savings is estimated at $5,500, for a capital expenditure of $25,000. The payback timeframe for this station would be 5 years. Reservoir Fill A volumetric analysis of the system under ultimate maximum month demand conditions indicates that imported water deliveries will be required to supplement the 16th Street/Wellfreld supply in order to replenish storage in Big Canyon Reservoir. This situation could also be remedied by additional wells and groundwater delivery capacity, as discussed in Section 6. Pressure Reducing Station Upgrades The City has identified a variety of vault, piping and electrical • upgrades required at 1 I of its pressure reducing stations, phased over the next 10 years, to be followed by general non - specific upgrades which will need to be performed in the subsequent 11 year period. The most substantial of these projects are the rebuilding of the Bayside Drive and Bayside/Marina PRS within the next two years. Table 7 -2, Part E presents a summary of these projects. Part E projects total $2,270,000 in 1998 dollars. LJ Meter Replacement, Reclamation, Fire Hydrant, and Miscellaneous Improvements Programs Refer to Table 7 -2 "Betterment Program Improvements," Parts G, H, I, and J, respectively, for a summary of these betterment programs as developed for implementation by City staff. Total cost for these improvements is $6,188,000 in 1998 dollars.
