The City operates a sewer collection system through its Department of Public Works. The Municipal Water Department has provided domestic water service to its customers since 190., assuring the city of an ample supply of potable water. The Department does not derive any of its revenue from the general or special tax base. c In October 1973, the Mayor and Common Council authorized the transfer of the wastewater treatment plant (Water Reclamation Plant) to the Board of Water Commissioners which governs the Department. The Board consists of five members appointed to staggered 6-year terms by the Mayor. The Department is directed by the Board and is a separate department operated independently of other city functions. The Department has control over water supply and distribution for the city and full management of fiscal responsibilities for the Water Reclamation Plant (WRP) and for applicable state and federal grants. The Board is empowered to establish and collect water rates, to hire employees, and to maintain, operate and expand the WRP as necessary. Q The Department provides wastewater treatment for the City of San Bernardino, East Valley Water District, the City of Loma Linda, Patton State Hospital, and Norton Air Force Base through the operation of the 30 MGD regional water reclamation plant. San Bernardino, Loma Linda and East Valley Water District each provide separate and independent sewage collection systems. East Valley Water District serves primarily the City of Highland. . The Department also participates, through the Santa Ana Watershed Planning Authority (SAWPA), in a joint powers authority with the City of Colton for completion of a regional tertiary wastewater treatment demonstration project. Full-scale tertiary treatment is required to achieve compliance with existing discharge permits issued by the State. Full-scale treatment will be designed in 1992 fOllowing demonstration of alternative treatment processes. In 1990, the Department contracted with Bartle Wells Associates to prepare a Sewer and Water Financing Plan for the S-Year Capital Improvement (Master) Plans for both the water and sewer systems. The capital charges required for these master pianned projects were used to establish the Financing Plan. The Department also contracted with John carollo Engineers to prepare a Revenue Program, in accordance with user charge requirements resulting from 1 - tJl "" J.. o o Q the Clean Water Act of 1977 and the Final Regulations of 1982, to establish the sewer rates necessary to generate revenue for the Water Reclamation Plant capital improvement projects. The intent of the Revenue Program, drafted in Hoveaber 1990 and finalized in June 1991, is to demonstrate and establish equitability of user rates based on the use of the treatment facilities. All new facilities under design, construction, or proposed to achieve compliance with state and federal regulations plus the required financing were evaluated for costs and subsequent revenue requirements. Data from both of these plans are incorporated into this study and referenced as supporting documentation for establishing the proposed sewer service charges and user rates. Analvsis of CaDital EXDenditure Reauirements c Recent major changes in the discharge standards have mandated construction of complete tertiary treatment and reduction in nitrogen and ammonia levels to protect aquatic life in the Santa Ana River, and groundwater quality. The South Coast Air Quality Management District's regulations now require off gas and process gas treatment equipment on most treatment phases at the San Bernardino WRP. The cost of solids handling and disposal, regulatory permitting, energy, labor, laboratory testing, and chemicals have escalated by 200 to 300 percent in the past five years. The Air Resources Control Board and the Air Quality Management District require water reclamation plants to do an extensive Air Toxics Hot Spots Inventory to determine if there are toxics given off by the various processes at the plant. The Department joined with several treatment plants throughout the state to do pooled emissions testing on certain processes; toxics testing, however, must be done at each facility. This inventory will cost San Bernardino approximately '300,000.00 in the next fiscal year. In September or October 1991, EPA is to publish new regulations on slUdge disposal. The Department must evaluate the new regulations and develop a long-term residuals management program that could include composting, incineration, or land application. To comply with discharge standards established by the Regional Board and to ensure reliable operations, a number of capital improvement projects have been undertaken; served additional cost- intensive projects are required to meet new EPA and RWQCB regulations. Projects that have been completed or are under construction include: c Solids Handling Facilities - 2 digesters, 2 dissolved air flotation units, methane gas scrubbing, holding and 2 o o G flare, sludge dewatering building, 2 belt presses, and loading facilities. Unit 1 3.5 MGD Secondary Clarifier - New clarifier and pump station for Unit 1 13 MGD facilities. Air Supply Corrective Action - New air supply building, electric motors, engines and blowers to supply air for the biological activated sludge process. Miscellaneous Improvements Project - Rehabilitation of pump stations within the plant to distribute waste activated sludge and various process wastes. "E" Street Pump Station - Upgrade and expand the pump station that brings influent into the plant from the south end of the city, the City of Loma Linda, the Auto Plaza, and a portion of "E" Street. Fine Bubble Diffusion Retrofit - Retrofit of all aeration basins in Units 1 and 2 from course bubble diffusers to fine bubble diffusers in order to nitrify and help meet ammonia discharge standards. o RIX Demonstration Project - 2 MGD demonstration project with the City of Colton to demonstrate that rapid infiltration of secondary effluent in spreading basins and then extraction of the water is equivalent to conventional tertiary treatment. Pilot Nitrogen Removal Project - 3 MGD of additional treatment capacity and reduction of total inorganic nitrogen to 10 mg/l and ammonia to 2 mg/l. This project takes the concentrated waste stream of nitrogen and ammonia from the belt press facility. Projects that must be built in order to meet current discharge requirements are as follows: () Full scale Rapid Infiltration/Extraction Facility (RIX) or Conventional Tertiary Facility - Facilities must be on line by 1995 to meet diSCharge requirements. San Bernardino's estimated share of the cost is '.0 million for RIX or '.5 million if conventional tertiary. Primary Hydraulic Reliability Project - This project is designed; construction is expected to begin by the end of 1991. It includes rebuilding the headworks of the plant where all influent enters into the treatment process. This project will provide metering structures, flow splitting to the primary clarifier, a septage receiving station, and preaeration to settle out solids 3 o o Q and debris. This project is necessary to any additional unit process can be built. facilities that were built in 1958. Phase 3A Secondary Project - This project will be required for either treatment plant expansion capacity or to meet more stringent nitrogen and ammonia discharge requirements. The Regional Board has proposed setting nitrogen limits of 10 mg/l on all flows; ammonia must also be reduced from 18 mg/l to 2 mg/l. If the nitrogen limits are established at 10 mg/l, the projects to meet the new standards will be required by 1995. If this project is built to satisfy the revised nitrogen standards, the next increment of secondary expansion must then be built. build before It replaces All of these projects add significantly to the costs of providing sewer treatment; the projects are built with funds raised from bond sales which then require annual debt service. The Sewer Fund Debt service will exceed '7 million per year to fund all of the projects which must be built to satisfy regulatory requirements. Analvsis of ODeratina and Maintenance Costs o In the past year, the 3.5 MGD Secondary Expansion, Solids Handling Facilities, and the Air Supply Corrective Action projects have been completed. Each of the projects has added reliability to the treatment process which is evidenced by improvements in the quality of discharges from the plant and meeting our HPDES Permit requirements. Chemicals, including chlorine, polymers for sludge dewatering, caustic soda for odor scrubbers, catalysts for reducing hydrogen sulfide, lime and soda ash are a major expense in operating a treatment plant. power, including electricity and natural gas, account for over 10' of the operating costs; personnel operate the plant around the clock every day of the year. Staffing levels have increased slightly due to the additional processes and equipment that have been added to the plant. This year, the Rapid Infiltration/Extraction Demonstration Project, a joint project with Colton, was initiated in May. The Department's portion of the cost for one (1) year of demonstration operation is $418,000.00. Most of the expenses, '300,000.00, is for the laboratory testing that is required by the Regional Board to demonstrate that this process is equivalent to conventional tertiary treatment. c Maintenance of the facilities is a critical function. The plant maintenance personnel must maintain over 3,000 pumps, motors, valves, and electrical equipment to ensure proper operation of the plant. The Maintenance Section has an ongoing preventive . o o e ..intenance program and does almost all repair work and fabrication in-house. Solids disposal is one area the Department has successfully reduced costs from two years ago. Previously, the sludge was dewatered and then blended with sawdust and other composting materials to reduce the moisture content to 50' and then disposed of at a landfill. The Department is now able to dispose of sludge directly from the belt press to two composting operations. The majority of the sludge is taken to One-Stop in San Timoteo Canyon and the balance goes to Chino-Corona Farms. c The plant operates a certified lab to run daily tests on influent, effluent, and plant process operating data. The current lab facility is inadequate and is scheduled to be relocated into the Blood Bank building within the next 18 months. When the lab is relocated, additional testing equipment that is needed to perform tests for heavy metals, sludge analysis, and trace organics in water and air samples will be acquired. The budgeted operational and capital costs, included in the Revenue Program developed by John Carollo Engineers, for the required facility upgrades are detailed on Table 1. The percentage of the total budget for each of these operational, maintenance, and capital costs is shown on Figure 1 which follows. o 5 o o "TABLE 1: SEWER FUND BUDGET" Q rosT Category (1) FY 1989/90 JY 1990/91 JY 1991/92 --------------------------------------------- ------------ ----------- -------- Treatment Facilities Direct Expenses: ------------------------------------ Plant Operations &: Maintenance: Salaries $1,344,175 $1,059,251 $1,400,610 Materials &: Supplies 238,194 264 ,565 262,343 Power 702,125 1,136,895 1,285,202 Fuel &: wbricants 385,276 387,764 361,710 Chlorine &: other Chemicals 771,159 835,301 1,096,412 Other 326,835 97,238 195,095 O&tf Services by am 120 0 Outside Labor 100,150 71,820 561,000 Permits &: fees 62406 319,590 Sludge Processing &: Hauling 1,208,423 894,689 829,203 Laboratory 222,588 307,711 ------------ ------------ ---------- Subtotal Direct Expenses $5,076,337 $5,032,597 $6,618,876 General Expenses: ---------------- Tool a.

The Department has determined that between July 1989 and June 1990 a total of 1,915 sewer capacity rights were assigned -- approximately 65 more than the annual full-growth assumption used in the Financing Plan. Completion of capital projects included in the Financing Plan will resul t in a design capacity of 48 MGD or approximately 37,500 BRU's. The Department has prepared an analysis of future capacity basin on various reports to determine projected wastewater flows from the entire service are. This analysis (prepared in February 1989) projected a total wastewater flow of 51.7 MGD at buildout. No evaluation was made as to the rate of growth. Included in this flow is approximately 2.6 MGD from uninCOrPOrated areas within the sphere of influence of the cities of San Bernardino and Loma Linda.

Connection Charaes c The existing connection charge designed for improvement of the wastewater treatment plant is '2,260, effective January 1, 1989, for residential units. The current fee is the result of a fee structure adopted in 1984 which increased annually for five years in recognition of escalation in construction costs as well as the future cost of money. These fees are based on the allocated costs of plant expansion directly related to growth (Le. a capacity charge) . Corresponding fees were also set for commercial and industrial users on the basis of volume of daily effluent flow; the current rate is '8.05/gallon. Based on the slow-growth scenario identified in the Financing Plan and the capital improvements required to support new growth, the following table indicates a 5-year schedule proposed for connection 9 1 .

An extensive sampling program was performed by City staff in 1988 to identify users and their respective wastewater strengths. Based on this sampling, ten user groups were identified: residential, mU1ti-fami1y-mobi1e homes, retai1-commercial-1ight-industria1, auto repair-carwash, offices-motels, restaurants-hotels, laundromats, hospita1s- convalescent homes, schoo1s-churches-nurseries and industry. The industrial group contains monitored users which have varying strength characteristics based on sampling and are listed separately. Individual contracts will be prepared/amended between the Department and these users to ensure their charges reflect equity based upon their impact to the system from excessive strengths of BOD and or Suspended Solids. Sewage flows for each nonresidential user were estimated based on water use records and discounted allowing for landscaping water and consumptive use not entering the sewer. Residential user sewage flows are based on water consumption of 255 gallons per day, per household, while multi-family and mobile homes users sewage flows are based on 190 gallons, per day, per household. The process used to develop the proposed rates is consistent with Federal regulations and State guidelines. These regulation and guidelines mandate that rates are equitably based on use of the facilities. Rates then are based on a user's shared loading to the facilities. This use is based on a discounted metered water flow and solids loadings consisting of BOD and Suspended Solids (SS). The Revenue Plan and proposed rate structure will assist the Department in planning for rates which will recover costs associated with operating and maintaining the new facilities. The City always has the option to change the rates, but must continue to assure that the rate structure recovers expenses from users based on use of the facilities. Based on budget information from the City of San Bernardino Public Works Department, the local collection system portion of the residential rate will remain unchanged. Below are the current rates for the two user types identified in the current rate structure. 10 Q () Q .:;I u. ~ - o o TABLE 3 CITY or SAN BElUfARDINO CURRENT SEWER UTILITY RATES AND CHARGES REGIONAL FACILITY & COLLECTION TOTAL TREATMENT SYSTEM CITY CHARGE CHARGE CHARGE User Charges (per month) Within City: Residential $6.05 $1.15 $ 7.20 Commercial (hcf) 0.37 0.08 0.45 Outside City: Residential 6.05 4.95 11.00 Commercial (hcf) 0.37 0.33 0.70 Individual industrial dischargers have contracts with the Department in which surcharges for excess loadings are identified for each user.

Attachment "A" shows the most recent data available for sewer service rates of surrounding communities. San Bernardino's proposed single family residential rate would be the second highest for mid 1991. 12 o c o j ~ ~ - ~ IlIl o o Most of the representatives interviewed indicated that their respective agencies have adopted policies of adjusting rates annually based on approved budget requirements. Conclusions EPA grant conditions and State guidelines require a user charge system be adopted which demonstrates fair and equitable charges to all system users. The 1990 Revenue Plan developed for the Department updates the sewer service rates to include the latest collection system costs, regional operation and maintenance (O&M) costs for fiscal year (FY) 1990-91 and anticipated additional debt service. Due to O&M increases and added debt service, the total budget (operating costs) has increased approximately 225 percent since the sewer service rates were last adjusted in 1983. To balance the budget, sewer service rates need to be adjusted accordingly. The net result is that residential sewer rates (single family, duplex, and triplex) would be increased nearly 89' for FY 1990-91. Approximately one-third of the proposed rate increase is attributed to the proposed added debt service associated with the Primary Hydraulic Rehabilitation and the Phase 3A Secondary projects' lease financing. The balance of the increase translates to an average annual increase of approximately five percent per year for inflation (since the last sewer service rate increased in October 1983) . The current costs associated with improvement of the treatment plant that are recovered from the sewer connection and capacity fees have increased annually in recognition of the inflationary costs associated with construction. The charges for these costs were increased 10' annually from 1984 to 1989. A 5-year schedule of connection fees is proposed for the period 1991-95. Based on these findings, it is recommended that the Board of Water Commissioners authorize the General Manager to request that the Mayor and Common Council set a pUblic hearing to consider adoption of these revised rates. It is also recommended that the Department and the City evaluate sewer service rates annually in order to minimize the future impact of required rate adjustments to the rate payer. 13 I. . . - , o o .A.

Listed on the attached Comparison of Sewer Rates, Table A, are the current residential and various commercial sewer service rates for local agencies within the Santa Ana region. Several of the agencies surveyed are in the process of updating their rates due to the capital and operational cost increases associated with meeting discharge requirements. Currently, of the cities listed on Table A, Rialto, Riverside, Redlands, and Colton are planning increases ranging between 10' and 60' by year end. Recent major changes in water quality standards have mandated construction of complete tertiary treatment and reduction in nitrogen and ammonia levels for all wastewater treatment plants that discharge reclaimed water to the Santa Ana River, to protect aquatic life and groundwater quality. Additionally, the South Coast Air Quality Management District's regulations now require off gas and process gas treatment equipment on most treatment phases. The cost of solids handling and disposal, regulatory permitting, energy, labor, laboratory testing, and chemicals have escalated an estimated 200 to 300 percent in the past five years. The Cities of Redlands' and Colton's sewer service Charges are currently higher than San Bernardino's current rate. Redlands charges $9.00 per month per residential unit, and '1.07 per one hundred cubic feet of water usage for general commercial customers. Redlands still has a comparatively lower treatment cost because they do not discharge their reclaimed water directly to the Santa Ana River. The City of Colton's current rate is $8.25 per month for residen- tial users, and '0.39 per one hundred cubic feet of water usage, plus an $8.25 minimum charge for all other users. The City provides for senior citizens to apply for an 18' lower rate ('6.80). The determination is based on age, flow, and financial status. The City of Colton will have to amend their policy of discounts since they have received low interest loan funds from the State Water Resources Control Board. o The City of Rialto's sewer service charge is '8.61 per month per residential unit, and '1.40 per one hundred cubic feet of water usage for non-residential customers with a minimum charge of '8.61 per month. 14 o () o - IU ..L. , o o The City of Riverside charge. their residential custo.ers '10.23 per aonth, plus a pUllping surcharge of U.50 per unit for all customers in areas requiring lift stations. Their commercial rate varies fro. '0.74 to U. 98 per one hundred cubic feet of water usage. The Yucaipa plant is relatively new and was partially funded by clean water grants; therefore, they have the lowest monthly residential rate ('6.50 per month) among the agencies surveyed. Commercial and industrial users pay on an equivalent unit basis a '6.50 plus applicable surcharges. The City of Corona charges their residential customers '12.05 per month; commercial customers are charged based meter size ('26.95 per month per equivalent 1" water meter size). Corona does not discharge their reclaimed water directly to the Santa Ana River. The City of San Bernardino's plant also treats the sewage for the Cities of Highland (via East Valley Water District) and Loma Linda, Patton State Hospital, and Norton A. F. B.
