01-21-1997 - Amendment to Water Leases with McIntyre Investments & the City of Covina0 TO: . City Manager and City Council FROM: Patrick J. Glover City Engineer/Public Works Director City of West Covina Memorandum AGENDA ITEM NO. C-6c DATE January 21, 1997 SUBJECT: AMENDMENT TO WATER LEASES WITH MCINTYRE INVESTMENTS AND THE CITY OF COVINA SUMMARY: Under the previously approved lease agreements with McIntyre Investments and the City of Covina, the City of West Covina may purchase 1870 acre feet (609 million gallons) of water per year from Covina Irrigating Company (CIC). ' This water is less expensive than water purchased from City's main supplier, Metropolitan Water District. Under the terms of the current leases, the City is to receive treated water which originates as surface runoff only (not well water). Limitations at CIC's treatment plant and other technical .complications have made it impossible for the City to take all 1870 acre feet of water per year. To ensure that the City is able to obtain the maximum amount of this less expensive water, staff proposes that the City agree to accept both surface water and well water and that the lease agreements be amended accordingly. BACKGROUND The City of West Covina owns and operates a water supply system which serves approximately 4200 customers in the southerly part of West Covina and approximately 2800 customers in Walnut. The system distributes approximately 7000 acre feet (2.3 billion gallons) of water annually. ' i Approximately forty percent of the City's service area lies within the Main San Gabriel Basin or its tributary areas. The customers who reside within this area use a combined average of 1870 acre feet of water annually: Unfortunately, even though many of the City's customers reside within the Main San Gabriel Basin, the City does not have the right to pump water from the Basin because the City was not a party to the original adjudication of water rights. In the absence of pumping rights, the City is forced to purchase the majority of its water from the Metropolitan Water District (MWD) via local municipal water districts. Over the past four years, the wholesale price of this ."imported" MWD water has increased approximately thirty-two percent (32%). The current wholesale rates for MWD water from the local municipal water districts range from $430.33 to $447.30 per acre foot (326,000 gallons). A few years ago, Covina Irrigating Company (CIC) contacted the City and indicated it could supply "local" water to the City system at a reduced cost. CIC is a privately held company governed by an elected Board of Directors. It has numerous share holders including the City of Covina and McIntyre Investments. CIC is an original party to the 1973 adjudication of water rights in the Main San Gabriel Basin. It receives an allotment of about 9700 acre feet annually which is distributed in proportion to the amount of stock held by each shareholder. Shareholders who do not use their allotment have arranged with CIC to make it available to other users through negotiated leases. It should be noted that purchasers of this surplus local water must both lease the rights to the water and also purchase the water itself. Amendment to Water Leases w IC Page 2 • In, 1994, the City, CIC, and the Water Master developed a three-way cooperative agreementwhich made the City eligible to receive a maximum of 1870 acre feet of water annually (when available) from the Main San Gabriel Basin via CIC. The agreement was executed. by the City Council in November of 1994 and by CIC and the Water Master in January_ of 1995. It was approved by the Superior Court of the State of California for the County of Los Angeles in May of 1995. In Fiscal Year 95/96, pursuant to the three way agreement noted above, the City leased a total of 2017 shares of CIC stock. (including 957 shares from the City of Covina and 958 shares from McIntyre investments). Each share of CIC Stock is equivalent to 0.9789 acre feet of water rights. Therefor, the shares leased by the City represented 1974 acre feet of water rights.. ; In Fiscal Year 95/96, the -City received approximately 450 acre feet of water from CIC at a wholesale, cost of $380 .per. acre foot. The acre foot cost includes: $260 for leased water rights,. $75.00 -to purchase the water from CIC, and $45.00 for the power to pump the water. Because of the reduced cost of this water when compared to the more expensive "imported" MWD water, the City realized a savings of about $30,000 in Fiscal Year 95/96. These savings offset increases in the wholesale price of MWD water which allowed the City to avoid a rate increase for its retail customers. Unfortunately, the City ' was not able to receive its full allotment'of 1870 acre feet as permitted under the three way agreement approved by the Water Master and the Superior Court. Some of the reasons for this are outlined below. The water leases weren't fully executed until September, 1995. • State mandated alterations to CIC's treatment plant weren't completed until December of 1995. • There wasn't sufficient surface runoff water available due to water quality and technical problems. These issues are discussed in more detail in the Analysis portion of this report. Since. the. Cityonly, received approximately 450acre feet in Fiscal Year 95/96, the remaining leased water rights (1522 acre feet) were carried forward into Fiscal Year 96/97. Thus, the City only needed to lease rights town additional 348 acre feet -for Fiscal Year. 96/97 in order to have sufficient rights to take the maximum permitted allotment of 1870 acre feet as approved by the Court and the Water Master. During the first six months of Fiscal Year 96/97, the City has only been able to take 114 acre feet of this less expensive water from CIC. This represents about 6% of the total permitted annual allocation of 1870 acre feet. ANALYSIS As noted above, the City only took a small portion of the allotment it was entitled to in Fiscal Year 95/96. If circumstances remain unchanged, it is projected that the City will only be able to take approximately 900 acre-feet in Fiscal Year 96/97 (less than one half of : the total allotment it is entitled to). The four primary circumstances which are preventing the City from receiving its full allotment are summarized below. 1. Lease Terms. The current lease agreement with CIC stipulates that the City will receive treated surface runoff water (which originates as precipitation in the local mountains) only. When the lease was initially negotiated, CIC informed the City that there would be sufficient treated runoff to satisfy the City's needs (which could not exceed 1870 acre feet under the Court and Water Master approved agreement). Since there appeared Amendment to Water Leases IC Page 3 VOP 0 to be sufficient treated surface water, it was agreed that the City would not have to accept any local well water. 2. Water Quality / Turbidity. CIC has a sophisticated water treatment plant on Arrow Highway in Glendora. This plant treats the surface runoff water from the local mountains which, under the terms of the current lease, is the only type of water delivered to the West Covina water system. Surface runoff (especially that resulting from heavy rains) contains suspended soil particles which are referred to as "turbidity." When turbidity exceeds the State mandated. limits, CIC is forced to shutdown the treatment plant and instead supply its customers with well water only. 3. Seasonal Limitations. In general, surface water is only available during the winter months. During the summer months, .no surface water is available and CIC delivers only well water to its customers._ For the remainder of the year, CIC either delivers well water or a mixture of well water and surface water. 4. Pumping / Mechanical Limitations The City pumps used to take CIC water were originally installed only to take water from CIC in an emergency when MWD could not deliver water due to. damage and/or required maintenance on their system. They are single speed pumps which requires a minimum constant flow of 1500 gallons per minute (GPM) to operate properly. As a result of items 1 through 4 above, the City can not take treated surface water: (a) in the summer because none is available; (b) in the winter when turbidity is excessive; (c) when CIC can not deliver at least 1500 GPM because the City pumps will not operate properly; and (d) when CIC must delivery a mixture of surface and well water to meet the combined demands of all of CIC's customers. . FISCAL IMPACTS Currently, the City purchases MWD water from Upper San Gabriel Valley Water District and the Three Valley Municipal Water District at the cost of $447.30 and $430.33 per acre foot, respectively. The wholesale cost of CIC water is approximately $60.00 less per acre foot. • For the current fiscal year, If the City takes 900 acre feet as projected, it will result in, a $54,000 savings when compared to the cost of MWD water. • If, through alterations to the leases and/or through mechanical alterations, the City could take 1200 acre feet, the City would realize a $72,000 savings when compared to the cost of MWD water. • If the City altered the leases to accept well water in addition to surface water and was able to take the full 1870 acre foot allotment, it would realize a savings of approximately $112,000. ALTERNATIVES 1. Modify the City Pumps. As noted above, the pumps used to take CIC water are single speed and require a constant minimum flow of 1500 GPM to operate properly. When the available water is less than 1500 GPM, the pump is turned off and the City receives no water from CIC. It is possible to install a variable speed control system for approximately $30,000. From a recent meeting with CIC, it is projected that with this type of system in place, the City would be able to take approximately 1200 acre feet in the current fiscal year (an increase of approximately 300 acre feet over the 900 acre feet currently projected). In the short term (considering only the current fiscal year), this will only result in an additional savings of $18,000 in wholesale water costs while . Amendment to Water Leases wi C Page 4 N costing the City $30,000 in system alterations. However, the alterations would pay for themselves in succeeding years if the City continued to lease rights and purchase water from CIC. When compared to Alternative No. 3, below, this alternative is not the most cost effective solution to the current problems. 2. Maintain the Status Quo. If the City is able to take the 900 acre feet projected for the current fiscal year, there will be significant savings when compared to purchasing all the water from MWD. However, it is very unlikely that the City would ever be able to take its full allotment of this less expensive water. This alternative would not maximize the City's savings. 3. Alter the Lease Agreements. If the lease agreements were immediately altered to accept treated surface water or well water or a mixture of both, it is projected that the City will approach the maximum allotment in the current year and would achieve the maximum allotment in future years. This would result in additional savings in the range of $58,000 (or a total savings of $112,000 when compared to MWD water) without any costly alterations to the City's system. The majority of City residents (those served by providers other than the City) are already receiving water from the well field where the CIC wells are located. This water is treated at the well head and is required to meet the same State Health Department Standards as the treated surface water being accepted by the City under the current lease agreements. RECOMMENDATION Staff recommends that the City Council authorize the Mayor and City Clerk to execute amendments to the existing lease agreements with McIntyre Investments and the City of Covina which will allow the City of West Covina to receive surface water or well water from the Covina Irrigating Company. atrick J.
