SR-9-B (8) . f-8 , 1=1 R -1 1 199" I '.J _t ~'L L EP:CP:SM:PhaseII Santa Monica, California council Meeting: February 11, 1992 TO: Mayor and city council FROM: city staff SUBJECT: Recommendation to Approve Phase II of the BAYSAVER Plumbing Fixture Rebate Program INTRODUCTION This report presents Phase II of the BAY SAVER Plumbing Fixture Rebate Program which will achieve the retrofit of an additional 25 percent of the residential households in the city and the retrofit of 25 percent of the commercial toilet fixtures in the city. BACKGROUND Since its implementation in December 1989, the BAYSAVER Residential Fixture Rebate Program has replaced 23,200 toilets and showerheads in Santa Monica, thus exceeding the program's 25 percent retrofit goal (19,200 bathrooms) three years sooner than originally planned. The City's water consumption and wastewater flows in 1991 were at their lowest levels in over twenty years. Achievement of the 25 percent retrofit goal has thus far represented savings of about $250,000 per year on imported water purchases from the Metropolitan Water District. Wastewater savings are represented through reduced costs for sewage treatment of about $340,000 per year as well as avoided costs for future treatment capacity expansion at the Hyperion Sewage Treatment Facility totalling over $4.0 million. 9-B r-....n r~r i 1 Joe? , Recently, the Metropolitan Water District informed staff that the Conservation Credits Program which supported about one-half of BAYSAVER program costs would not be available for Phase II due to proposed MWD budget cuts. The proposed Phase II of the BAYSAVER program has been designed to reflect this change as well as other modifications to ensure program goals are achieved with maximum cost effectiveness. DISCUSSION The City anticipates that local demand for water-conserving fixtures will continue to increase based on growing acceptance of ultra low flow toilet performance/reliability and the need for conservation beyond the duration of the current drought. Ultra low flow toilet replacement programs have been approved by the Urban Water Management Council (Santa Monica is a member of the steering committee) as a Best Management Practice, thereby becoming a required program by signatories to the recently enacted Memorandum of Understanding Regarding Urban Water Conservation in California. California's Health and Safety Code has been amended to require that all new construction use 1.6 gallon per flush toilets and 1 gallon per flush urinals effective January 1, 1992. Plumbing fixture manufacturers have responded to these and other State legislative actions by marketing ultra low flush fixtures for every type of plumbing configuration and occupancy. Establishment by City council on April 1, 1991 of a mandatory 20 percent water cutback and penalty surcharges for exceeding water 2 ---- ----- targets had a dramatic impact on overall city water consumption levels and expedited achievement of the BAYSAVER program's 25 percent retrofit goal. Approximately 845,000 gallons per day of the City's total water savings are attributable to the BAYSAVER program, and these savings represent permanent water consumption reductions. Many behavioral changes motivated by the mandatory cut backs will most likely not continue after cessation of the drought. Even with a possible end to the drought, however, water supplies from the state and from the Metropolitan Water District may remain at current reduced levels. Therefore, participation in the BAYSAVER program should remain strong and allow the City to achieve the permanent water savings necessary to maintain our greatly reduced water consumption levels well into the foreseeable future. Residential Program Modifications Phase II of the BAYSAVER Fixture Rebate Program will accommodate ongoing public demand by achieving the retrofit of an additional 25 percent of the residential households in the City within three years. To achieve a fifty percent residential retrofit target, an additional 19,200 ultra low flush toilets and low-flow showerheads will be installed in Santa Monica, or 6,400 per year in each of the three years. The rebate program and the direct installation option will function similarly to previous years with the following exceptions: 3 1) Rebates will be lowered from $100 to $75 for each bathroom retrofitted as a cost-cutting measure, which is also justified by the fact that the cost of ultra low flush toilet have dropped as availability has increased; and 2) The direct installation option customer co-payment will be increased from $25 to $35 per bathroom since program costs are higher than originally estimated due to higher plumbing contractor installation rates and storage/handling costs. Non-Residential proqram Phase II proposes a 25 percent retrofit target for non-residential business/commercial occupancies. It is estimated that there are approximately 20,000 non-residential toilets in Santa Monica of which 16,700 are older, water-wasting models. A $75 rebate in the form of a utility bill credit will be offered for every toilet retrofitted. The direct installation option will not be offered to non-residential customers as such occupancies often have property maintenance services available, are capable of completing necessary plumbing work without the use of plumbing contractors, or have leasing agreements in which lessees pay their own utility bills. Non-residential fixture configurations are generally of two types: elongated tank toilets or flushometer valve/bowl combinations. Either configuration can be retrofitted with 1.6 gallon per flush models which have passed American National standards Institute 4 (ANSI) tests and are readily available at local plumbing suppliers. New ultra low flow models for commercial plumbing configurations are continually being introduced and the level of confidence in these products will increase as more businesses use them and experience significant water savings. The $75 rebate credit covers approximately half of the cost of the less expensive commercial models, and it is estimated that total customer out-of-pocket costs can be easily recovered through water and wastewater bill savings within two years, depending on the amount of water use and the type of installation which was required. It is estimated that, on average, each commercial toilet retrofit will save approximately 60 gallons of water per day. Low flow showerheads and faucet aerators will also be required to obtain the rebate credit, where applicable. Showerheads can be obtained free of charge from the city. Rebates will be issued through a credit on the customer's utility bill and will be administered by Conservation Office staff. Any ultra low flush plumbing fixtures installed in new construction or building remodels as a requirement of the City'S plumbing code will not be eligible for a rebate credit. S Implementation/Customer Outreach strateay Notification of the lower rebate and increased direct installation fee for the residential program will be made through utility bill inserts, local media advertisements, and printed materials distributed at City facilities. Residents will be able to take advantage of the current rebate amount of $100 provided that the rebate application is received by the City's rebate processing contractor before a targeted date. This targeted date will be noticed on the billing inserts, ads, and printed materials. After that date, all applications for rebate or direct installation will receive the $75 rebate or pay the $35 installation fee. All existing BAYSAVER printed materials will be revised and reprinted to reflect the new rebate/fee structure. To ensure that the non-residential rebate program receives a favorable reception from the local business community, staff will meet with the Chamber of Commerce and other groups to present the proposed program, and will work with these groups to accommodate their particular needs. Notification of the non-residential program will be made via utility bill inserts to non-residential water customers, targeted direct mailings to specific businesses, and presentations to local business organizations. Conservation staff will be available to visit local establishments to perform water use audits, discuss the rebate program, and respond to any other questions/concerns. 6 - - -- -- - Proposed proqram Budqet The FY 1991-92 Budget for the Environmental Programs Division includes funding for the retrofit of 10,000 residential bathrooms in the city. This one year budget goal of 10,000 retrofits was actually reached within five months, by December 1, 1991. The much higher than expected demand for the BAY SAVER program has been primarily related to the City's emergency water conservation ordinance and the popularity of the direct install option for mUlti-family property owners. For purposes of the proposed Phase II program, it should be noted that the completion of the budgeted 10,000 retrofits results in a BAYSAVER total, since the inception of the program two years ago, of 23,200 bathroom retrofits. This number is 4,000 bathrooms more than the original 25 percent BAYSAVER goal of 19,200 bathrooms. The 25 percent retrofit milestone was actually reached on about October 1, 1991. The city, therefore, has already accomplished 4,000 residential retrofits towards the new 25 percent residential retrofit goal which is proposed for the Phase II BAYSAVER program. The budget estimates for Phase II reflect the reduced costs due to this "headstart" of 4,000 retrofits. The estimated total budgets for the residential and non-residential BAYSAVER programs are listed below. As with the previous BAYSAVER program, the City intends to contract with a private firm for application processing, inspection services, scheduling of plumbing contractors for the direct install program, data collection and 7 - -- -- - --- -- - -- - - ------- . , other related services. It is proposed that the City enter into a new contract with DMC Services, Inc. , the firm currently under contract with the City, to provide implementation assistance for the proposed Phase II program. This recommendation is based on the City's experience to date with DMC's performance under their current BAYSAVER contract.

Sources of proqram Fundinq Approximately one-half of the BAYSAVER program costs dur ing the first phase of the program have been paid through a conservation credit from the Metropolitan Water District. The city has recently been informed by the MWD that they are not able to fund a continuation of the BAYSAVER program at this time due primarily to MWD budget constraints. Given this loss of MWD funding support, it is proposed that the Phase II program be funded through a combination of BAY SAVER Fees (a monthly amount charged to all residential households who have not yet retrofitted their toilet fixtures); Water Mitigation Fees (a charge for mitigation of water 9 - demand from new development); and a very minimal amount of water user charges during the last fiscal year of the program. This proposed financing strategy represents an almost completely self- funded BAYSAVER program since only special fees which have been specifically established in order to support the city'S plumbing fixture retrofit efforts would be tapped. It is estimated that $51,185 of general water revenues would be required to support the proposed $2.4 million BAYSAVER budget. BAYSAVER Phase II Sources of Funding Fundinq Source FY 91-92 FY 92-93 FY 93-94 TOTALS BAYSAVER Fee* $ 274,000 $ 415,500 $ 295,500 $ 985,000 Mitigation Fee** 330,082 632,496 443,422 1,406,000 Water User 0 0 51,185 51,185 charges*** ---------- ---------- ---------- ---------- TOTALS $ 604,082 $1,047,996 $ 790,107 $2,442,185 *Assumes continuation of the $2.00 per month single-family BAYSAVER fee and the $1.35/month{dwelling unit mUlti-family BAYSAVER fee. This fee is removed once a household/dwelling unit has been retrofitted with ULF toilets and low-flow showerheads. **Assumes that the current emergency ordinance requirement for mitigation of two times (2X) gross flow from new development (including substantial remodels) remains in effect until May 1, 1992 at which time it is replaced with a permanent requirement for the mitigation of one times ( 1X) gross flow from new development. ***These user charges represent the bi-monthly fees based on water meter size and actual water usage which are paid by all residential and commercial customers. General user charges would not be required to subsidize the Phase II program until FY 1993-94. 10 . BAYSAVER and Water Mitiqation Fees It is proposed that the Baysaver Fee be continued for the duration of Phase II at its current level of $2.00 per month for single- family dwelling units and $1.35 per month per dwelling unit for multi-family buildings. The BAYSAVER fee is removed when a dwelling unit has been retrofit with ultra low-flow toilet fixtures and low flow showerheads. As more residential dwelling units participate in the BAYSAVER program, the proceeds from the BAYSAVER fee decline. This decrease has been built into the revenue estimates presented above. There are two main reasons why it is not recommended that a new BAYSAVER Fee be established for non-residential customers who will, for the first time, be eligible for the retrofit program. First, the residential BAY SAVER fee is charged based on the number of dwelling units represented by a particular customer account. Information on the number of dwelling units is readily accessible on the utility billing system and allows for consistent tracking of fee amounts and fee removals. Non-residential accounts do not possess a similar common denominator for purposes of charging an equitable BAY SAVER fee. If a fee were to be charged to non- residential customers for financing their portion of the BAYSAVER budget it would probably have to be in the form of a surcharge on each billing unit of water used by a particular customer. staff does not feel that this would be an equitable system, however, since the proportion of water use related to toilet flushing varies 11 ~ significantly from business to business. Also, there are hundreds of accounts which would need to be manually exempted from such a charge due to the fact that they have already installed ULF toilets either through their own retrofit efforts or due to the fact that they were constructed after July, 1988 when ULF fixtures became a code requirement. An additional reason for not implementing a commercial BAYSAVER fee is tied to the fact that revenues which have been and are anticipated to be realized from the city's water mitigation fee program are sufficient to cover the costs of all of the commercial retrofit program and much of the residential retrofit program. The water mitigation fee program is charged to all new single-family residential construction which results in an increase in total square footage of more than 50 percent; all new mUlti-family residential construction which results in the addition of one or more units; and all new non-residential construction which results in an increase in the total number of plumbing fixtures. Currently, each applicable building permit applicant is required to mitigate two times the projected total water demand from the new project by paying $3 for each gallon per day (gpd) which must be mitigated. Between April 1 and December 1, 1991, approximately $600,000 in water mitigation fee revenues were collected. To date, about $300,000 of these mitigation fees have been used to retrofit almost 1,600 fixtures in city buildings, public schools, Santa Monica 12 ------ > College, numerous non-profit facilities, and low/moderate income housing. It is proposed that the remaining balance of water mitigation fees as well as the future revenue stream be used to offset the Phase II BAYSAVER program budget over the next two to three years. It is further proposed that council direct staff to evaluate the best way in which the present emergency water mitigation program can be replaced by a permanent water mitigation requirement for new development tied perhaps to a one times (lx) rather than a two times (2x) mitigation threshold (each new project would be required to mitigate one times the total projected water usage) . The revenue projections presented above and in Exhibit I assume that such a permanent water mitigation ordinance would be in effect by May 1, 1992. Reduced Water Usage and Sewage Flows The estimated water savings (and sewage flow reductions) from the proposed Phase II BAYSAVER program are presented below for both the residential and commercial components of the program. Upon the completion of Phase II in March, 1994, the city will have achieved a permanent reduction in water usage and wastewater flows of 1.1 million gallons per day (mgd). When combined with the results of the Phase I BAYSAVER program, the cumulative savings will total over 1. 9 mgd. These 1.9 million gallons per day of reduced water usage and decreased sewage flows represent a 15 percent reduction in Santa Monica's average total daily water demand and a 19 reduction in average total daily sewage flows. This magnitude of 13 - - - --- -- -- permanent flow reductions would represent a tremendous accomplishment by Santa Monica residents and businesses. A ten year analysis of the cumulative financial costs and benefits from the completed Phase II BAYSAVER program is presented in Exhibit I. If a comparison is made solely between the cost of imported MWD water and the cost of water savings through the retrofit program, it becomes clear that by the end of ten years the retrofit option will result in a significant cost savings to the city. Analyses of imported water costs over the next ten years vs. costs for both residential and commercial retrofits under the proposed Phase II program are presented in exhibit II and exhibit III. BUDGET/FISCAL IMPACT The various revenue and expenditure impacts in FY 1991-92 which will result from approval of the proposed retrofit program are summarized in Exhibit I. Approval of the staff recommendation will result in an appropriation increase of $604,082 to the BAY SAVER account in the Environmental Programs Division (financed by a transfer from the Water Fund). This amount is offset by the estimated revenues which will be collected from BAYSAVER Fees and Water Mitigation Fees. After considering the savings from reduced MWD water purchases and decreased revenues from reduced water usage, the net impact on the Water Fund in FY 1991-92 would be a loss of $69,000. 14 In the Wastewater Fund, the proposed Phase II program would result in a revenue loss which from FY 1992-93 on will be largely offset by a reduction in Hyper ion sewage treatment costs from lessened sewage flows. The net impact on the Wastewater Fund in FY 1991-92 would be a loss of $169,000. Without a reduction in sewage flows, it is expected that by FY 1999-2000 the city will be required to purchase additional treatment capacity rights from the city of Los Angeles. without the Phase II BAYSAVER Program, it is estimated that the cost for the purchase of additional sewage treatment capacity by the City in FY 1999-2000 would be $8.2 million. It should be noted, however, that the need to purchase additional sewage treatment capacity is subject to a complex set of legal and policy determinations which will require future resolution. One of the consequences of the increased water conservation which is made possible by BAYSAVER program retrofits is a permanent reduction in revenues accruing to both the Water and Wastewater Funds. This decrease in revenues is expected to create short-term cash flow issues in the Wastewater Fund until such time that the substantial long-term benefits from reduced sewage treatment capacity needs are fully realized. In order to address this short- term revenue shortfall caused by the BAY SAVER program it is proposed that emergency conservation surcharge penalty payments be split evenly between the Wastewater and Water Funds starting July 1, 1992. Currently, 100 percent of these penalty payments are credi ted to the Water Fund. This is a more equitable method for 15 . distributing emergency surcharge revenues and allows the city to more effectively direct the funds toward their intended purpose, the support of on-going conservation efforts such as the BAYSAVER program. Adjustments in interfund transfer amounts between the Water and Wastewater Funds will also be requested as a part of the Proposed FY 1992-93 Budget to more equitably distribute the program costs and revenue impacts associated with the BAYSAVER program and other water conservation/wastewater reduction programs. There are currently sufficient reserves in the Water and Wastewater Funds to finance the projected costs of the BAYSAVER Phase II program in FY 1991-92. The specific budget changes which would be necessary following council approval of the Phase II program are listed below.
