3 SRCSD Interceptor System Master Plan 2000 Chapter 9 Recommended Capital Improvement Program 9.1 Recommended Capital Expenditures The recommended SRCSD Interceptor System Master Plan Capital Improvement Program contains 52 projects required to convey wastewater flows from existing and planned development to the Sacramento Regional Wastewater Treatment Plant. The facilities are scheduled to be constructed over the next 35 years, and when operational, will provide capacity for all planned development within the Urban Services Boundary and West Sacramento. The total capital cost of the master planned facilities is $950,100,000. This cost is in year 2000 dollars and does not include inflation or interest adjustments for any of the identified projects. The capital cost of each project is shown in Table 9-1. The capital expenditure per year is shown on Figure Schedule of Improvements The improvements identified in MP 2000 have been assigned start and completion dates based on the anticipated need for each facility to be operational. The start and completion dates for each project are contained in the project schedule, Figure 9-2. A large format, more detailed project schedule may be found in the appendix of this report. A visual representation of the recommended project implementation over time is shown in Figures 9-3 through Project Prioritization The recommended interceptor projects were developed to address existing and future capacity deficiencies in the existing interceptor system, and to extend conveyance facilities to planned development within the SRCSD service area. Each project was categorized into one of three types of project justifications: Category A: Category B: Category C: Required to relieve existing capacity deficiency Required to relieve future capacity deficiency Required to provide conveyance of wastewater generated from future planned development beyond the reaches of the existing interceptor system S:\MP 2000\Draft MP2000\Chapter 9\Chapter 9.doc 9-1

14 SRCSD Interceptor System Master Plan 2000 As shown in Figure 9-1 there is a spike in project expenditures between the years 2002 and This period of high expenditures is primarily caused by the construction of three major interceptor projects: Bradshaw/Folsom, Upper Northwest, and Lower Northwest. The yearly expenditures for these projects are shown in Figure 9-9. The Bradshaw/Folsom and Upper Northwest Interceptors are required to relieve existing capacity deficiencies in the SRCSD interceptor system and CSD-1 trunk system. Although the project segments of the Lower Northwest Interceptor are classified as Category B projects, they are required to provide relief to the Natomas and Arden Pumping stations. Each of these pumping stations are being upgraded to increase capacity, however, this is intended to only be a stop-gap measure to allow a reasonable timeframe for the design and construction of the Lower Northwest Interceptor. 9.3 Comparison to Previous Master Planned Expenditures The 1994 update to the Sacramento Sewerage Expansion Study (SSES) estimated the total capital cost of the recommended interceptor projects to be $595,100,000 (1993 dollars). The current MP 2000 estimate is $966,700,000. The major increases in project costs accounting for the $371,600,000 increase are itemized in Table 9-3, below. The difference between the $385 million total increase and $372 million difference from the previous master plan is due to a net cost savings on other projects contained in the MP TABLE 9-3 PROJECTS CONTRIBUTING TO INCREASED PROGRAM COSTS Item: Inflation (ENR CCI) Lower Northwest Interceptor Upper Northwest Interceptor Newly Identified Projects Total: Increase: $93 million $148 million $61 million $82 million $385 million A description of each of these items is presented below. Inflation - The Sacramento Sewerage Expansion Study Update used an ENR Construction Cost Index (CCI) of 5,600 which represented the mid-point between the 20-cities index and the San Francisco index at the time the estimate was being generated. The January 2000 value of this index is This represents a 15.6% increase due to inflation of the seven-year period and results in an $93 million increase in program costs. Lower Northwest Interceptor The SSES estimated the cost of the Lower Northwest Interceptor to be $95 million (2000 dollars). The MP 2000 estimate for these facilities is $243 million. The MP 2000 assumes a West Sacramento route for the Lower Northwest Interceptor and increases the size of the interceptor facilities S:\MP 2000\Draft MP2000\Chapter 9\Chapter 9.doc 9-3

16 SRCSD Interceptor System Master Plan 2000 to provide conveyance capacity for West Sacramento. A cursory review of the original estimate revealed some additional reasons for the large discrepancy. Approximately half of the base pipeline cost from the SSES was based on a unit cost for 72-inch force main of $320 per foot. This unit price appears to be low for the type of area the pipeline is routed through. Additionally, the $5 million base cost of expanding the Natomas Pump Station to 73 mgd appears to be low. Upper Northwest Interceptor The Upper Northwest Interceptor was estimated at $89 million (2000 dollars) in the SSES. The estimate from the Upper Northwest Interceptor Design Report is approximately $138 million, and the MP 2000 estimate is $150 million. The increase is primarily attributable to the increased capacity of the facilities identified in the design report to divert additional flows from impacted trunk facilities in the northeast system. Additional costs are also expected to be incurred due to the combination of poor soil and accelerated development in the North Natomas Area. The increase from the Design Report estimate to the MP 2000 estimate was related to the need to increase the size of the interceptor to convey higher flows based on modeling results, and costs associated with deepening the pipeline to provide gravity service to a larger portion of the service area. Newly Identified Projects The Interceptor System Master Plan 2000 has identified additional projects beyond those identified in the SSES that will be required to provide conveyance capacity to serve ultimate development within the Urban Services Boundary. These projects include the ARPS (Arden Pump Station Modifications), FS-1 (Folsom South Pump Station and Force Main), and AJ-1 through AJ-4 (AeroJet Interceptor). Modifications to the Arden Pump Station are needed to bring its capacity up to the value assumed in the SSES (approximately 105-mgd). The Folsom South Pump Station was required due to the realignment of Folsom East Interceptor Section 3 to Iron Point Road. The AeroJet Interceptor is required to provide service to the Mather/AeroJet Area. This area was originally identified as not requiring sewer service. However, due to changes in land use planning since the SSES, this area has been assigned an average development density of 6 ESD per acre. A comparison of expenditures in relation to time between the SSES and the MP 2000 is shown in Figure To estimate expenditure over time for the SSES the capital cost for each phase was divided evenly by the number of years per phase. The costs associated with interceptor projects completed to date are indicated in red. The total costs to date for the previously construction interceptors have been added to the cumulative MP 2000 costs in order to compare with the previous estimates of the entire program. As indicated in Figure 9-10, total expenditures since 1993 have been less than projected in the 93/94 SSES. This indicates that not all improvements identified in Phase 1 of the 93/94 SSES were completed on schedule. The delay in the construction of these facilities has contributed to the expenditure spike projected between the years 2002 and S:\MP 2000\Draft MP2000\Chapter 9\Chapter 9.doc 9-4

18 SRCSD Interceptor System Master Plan Guidelines for Implementation The MP 2000 provides a detailed plan of the interceptor facilities and right of way necessary to provide sewage conveyance within the Sacramento County USB and city limits of West Sacramento. Timing of interceptor projects identified for construction within the next 20 years is based on the operational condition of the existing regional facilities and/or SACOG growth projections within the study area. Projects identified for construction after the year 2020 are based on buildout densities within the USB that are not associated with a particular timeframe. Projects scheduled after 2020 are intended primarily to identify facilities required to provide service under a developed USB scenario. As the case with previous master planning efforts, the MP 2000 should be consider a working document and subject to review at least every year and updated every five years. Table 9-4 summarized the recommended interceptor projects, describes project drivers and timing considerations, and assigns a priority level to the project Project Verification The modeling results of the expanded interceptor system during a 10-year design period storm at buildout of the USB predict two interceptors with significant surcharging caused by limited pipe capacity. These facilities are the McClellan Interceptor and the Laguna Interceptor. The predicted surcharging may be caused by inaccurate flow monitoring information. It is recommended that additional flow monitor analysis be performed in these areas and the hydraulic model be recalibrated before identifying future relief projects. If major land use changes have occurred since the completion of this MP 2000, design flows should be updated and the hydraulic model re-run to determine the impacts the land use changes have on the interceptor system. Finally, the SRCSD should continue metering flow at strategic locations along the interceptor system. This data should be used to verify and update regional inflow coefficient (Kp) values throughout the service area. By periodically updating the hydraulic model with this information, the SRCSD may accelerate or delay recommended projects based on the most recent system response information.
