Director of Public Works Z:\engineer\documents\Resolutions\PR15460.doc EXHIBIT A Water Conservation Pfan I. Purpose Water conservation and drought contingency plans are required by the Texas Water Development Board (TWDB), set forth in the Texas Water Code, for those applications seeking financial assistance over $500,000 from water and wastewater project fund accounts. This water conservation and drought contingency document is written to provide the City of Port Arthur with plans and methods to use water more efficiently by reducing the consumption and loss or waste of water. It also contains a plan for implementing measures to significantly, but temporarily reduce water use during drought conditions or other emergency situations. I1. Planning Area Raw water is supplied to Port Arthur through a canal system owned and operated by the Lower Neches Valley Authority (LNVA). The City of Port Arthur operates a surface water clarification and filtration facility with a firm capacity of 20.0 mgd and a peak capacity of 26.0 mgd. The water treatment plant produces all of the City's potable water. The planning area encompasses southern Jefferson County which is presently served by the City's water treatment plant through its water distribution system. The area consists of the City of Port Arthur, and has a population of approximately 57,755 persons and an area of 140.64 square miles. III. Utility Evaluation Data The City of PortArthur utilizes Texas Water Development Board guidelines, historical data obtained from our accounting and operational records, along with benchmarking 1 of 13 information from similar sized cities. In March 2006, JBS Associates completed a Water Distribution System Audit to identify and address unaccounted-for water and develop recommendations to implement which will save water. IV. 5-Year and 10-Year Targets and Goals The City has established goals of reducing un-metered losses by 75% over the next 10 years, from 3,000,000,000 gallons per year to 750,000,000 gallons lost per year. The City has also established a goal of reducing average per capita consumption to the Texas Water Conservation Implementation Task Force recommended statewide goal of 140 gpcd, a reduction of 35% from the current level of 214 gpcd. Just before the turn of the century, the City completed the replacement of all unlined cast iron 12" water mains with newer technology materials. This effort is continuing with the following targets. 5-Year Targets 8 Goals Un-metered Losses Over the next five (5) years, the City has established a goal of reducing un-metered losses by 50%, an average of 10% reduction per year. To accomplish this, the City is planning to implement the following Best Management Practices (BMPs): 1. Metering of All New Connections and Retrofit of Existing Connections -completing the Automatic Meter Reader (AMR) Meter Change-out Program, and continuing to enforce the requirement for metering all new customer connections. 2. System Water Audit and Water Loss -the replacement of all 16"and larger cast iron and all sizes of concrete steel cylinder pipe. The City still has an abundance of 16" through 24" lead-joint cast iron pipe and 10" & 24" concrete steel cylinder transmission line. Phase II of our Water Line Replacement Program is targeted at replacing approximately 20 miles of mains with the worst leak history. Phase I ($5M), of this program was completed in 2005, which has resulted in a 35% reduction in main line leaks over the previous five year average. 2of13 Per Capita Consumption The Texas Water Conservation Implementation Task Force has recommended a statewide goal of reducing average per capita consumption to 140 gpcd. Current usage for the City of Port Arthur is approximately 214 gpcd. Reducing the un-metered losses as stated above would bring the average per capita consumption to 143 gpcd within this five (5) year term. In addition, to encourage conservation by its customers, the City is planning to implement the following BMPs: 1. School Education -distribution of educational materials from the Texas Water Development Board, 2. Public Information -posting conservation information on the government television channel, on water bills, and in local media, and providing leak detection kits to the citizens, 3. Prohibition on Wasting Water -implementation and enforcement of the Water Conservation Plan, 4. Golf Course Conservation -using irrigation water from the regional drainage district, 5. Water Wise Landscape Design and Conversion Programs -requiring that only certified irrigation specialists install irrigation systems in accordance with State water conservation rules. 10-Year Targets & Goals Un-metered Losses Over the next ten (10) years, the City has established a goal of reducing un-metered losses by an additional 25% of the current amount, an average of 5% reduction per year. This will bring the total reduction in unaccounted water loss to 75%from the present amount- from 3,000,000,000 gallons per year currently to 750,000,000 gallons per year. To accomplish this, the City is planning to continue to implement the following BMPs: 1. System Water Audit and Water Loss -the replacement of all 8"-10" cast iron pipe. The City still has an abundance of 8" cast iron pipe with a poor leak history. This size pipe contributes to much of our water loss due to its size and poor condition. 3of13 Per Capita Consumption Continuing the reduction of un-metered losses as.stated above will bring the average per capita consumption over the next ten (10) years to 108 gpcd -exceeding the statewide goal. The City is also planning to continue implementing the following BMPs to encourage conservation: 1. School Education -distribution of educational materials from the Texas Water Development Board, 2. Public Information -posting conservation information on the government television channel, on water bills, and in local media, and providing leak detection kits to the citizens, 3. Prohibition on Wasting Water -implementation and enforcement of the Water Conservation Plan, 4. Golf Course Conservation -using irrigation water from the regional drainage district. 5. Water Wise Landscape Design and Conversion Programs -requiring that only certified irrigation specialists install water efficient irrigation systems. V. Education and Information The City of Port Arthur promotes water conservation by informing water users about the ways to save water inside of homes and other buildings, in landscaping and lawn uses, and in recreational uses. These tips are included with the customer's monthly water bills. Additionally, water conservation literature is available to new customers when they apply for service at our customer service department. VI. Water Conservation Oriented-Rate Structure Water Conservation oriented-rate structures are used to discourage the waste of water. The City of Port Arthur currently has a uniform rate structure for water users which discourages water waste. All water customers are subject to the uniform rate structure. 4of13 VII. Universal Metering and Meter Repair and Replacement All water users are currently metered. Currently, the City has a water accounting program that is implemented by computerized water consumption tracking. Utilizing the computer, the City can monitor each metered connection for consistency in water use. If water consumption increases or decreases dramatically, the suspect meter is tested and repaired or replaced. As a result of this effort, the City tests approximately 100 meters and replaces approximately 1,250 meters annually, with replacement based on test results orthe age of the meter. The City recently acquired a meter test bench for meters from 5/8" through 2", and employees have been trained in its use. Meters larger than 2"are tested by an outside firm. In 2006, the City initiated a program to replace its commercial and hard to read meters with Automated Meter Reading (AMR) technology units. In late 2008, this program was expanded to include the replacement of all meters with AMR technology units. This will assist our personnel in obtaining regular meter .readings, and will replace our old, under- registering meters. The AMR metering system selected for implementation is capable of logging water use every four (4) seconds and that data can be provided to the customer to document and correct leaking private services. The AMR meter change-out program should be completed in 2010. The City of Port Arthur's water system is a compilation of numerous old former Water Districts and small cities that have merged with Port Arthur, and is spread out over a large service area. The City has initiated sub-basin metering to document water loss in remote transmission lines between these service grids. Much of ourtransmission system traverses remote, poorly accessible areas. VIII. Leak Detection and Repair The Utility Operations Department continues to cross check Production vs. Consumption in an effort to narrow the gap and eliminate water losses due to large leaks and theft of 5of13 service. Elevated storage tank levels and all pump stations are monitored 24 hours per day to alert repair crews of major leaks. The City has also recently implemented procedures to better account for water losses due to leaks and water main flushing. The City has also budgeted for the acquisition of an ultrasonic leak detection system that should assist field personnel in the location of hidden underground leaks. A leak detection crew will systematically begin a program to analyze areas targeted in our 2006 Water Distribution System Audit. IX. Means of Implementation and Enforcement The City Council of Port Arthur passed Ordinance No. 80-61 on July 21, 1980, which establishes a policy for water conservation. The ordinance authorizes the City Manager to implement and develop the Water Conservation Plan as required by the water supply and demand conditions in the City's water supply system. The ordinance gives the City Manager the legal authority to enforce the Water Conservation Plan and includes penalties for violations. This ordinance is included in the Code of Ordinances Section 110-34. Also in the Code of Ordinances is Section 110-70, "Discontinuance of Service", which provides for termination of service for any consumer violating or permitting violation from his attachments of any of the utility operations department's rules and regulations governing the introduction, supply and consumption of water. Further, the City Council passed Ordinance No. 09-_ on August 25, 2009, adding Code of Ordinances Section 110-34(d) and providing for fines of up to $2,000, or the maximum allowed by law -whichever is greater, for failures to comply with City's Water Conservation and Drought Contingency Plans. 6of13 X. Annual Report The City of Port Arthur provides an annual report to the TWDB that includes water audit information. XI. Pressure Reduction The City's water distribution system does not provide pressures in excess of 80 psi for any of its service connections. Therefore, there is no need to provide any reduction in pressure to reduce water consumption. XII. Recycling and Reuse The City of Port Arthur owns and operates four wastewater treatment plants. The Sabine Pass Wastewater Treatment Plant is permitted for 0.3 MGD and discharges into the Sabine Pass Channel of the Neches-Trinity Coastal Basin. The Pleasure Island Wastewater Treatment Plant is permitted for 0.1 MGD and discharges to the Sabine-Neches Canal of the Neches-Trinity Coastal Basin. The Port Acres Wastewater Treatment Plant is permitted for 2.75 MGD and discharges into Rhodair Gully. This WWTP recycles plant effluent (process water) for general plant clean-up uses. The City of Port Arthur's Main Wastewater Treatment Plant is permitted for 9.2 MGD and discharges into the Sabine-Neches Canal of the Neches-Trinity Coastal Basin. This WWTP recycles plant effluent (process water) for general plant clean-up uses. The City of Port Arthur Water Purification Plant recycles filter backwash water and water decanted during our dewatering process. 7of13 XIII. Plumbing Codes The 72"d Texas Legislature passed legislation requiring that plumbing fixtures sold in Texas after January 1, 1992 be water efficient. The standards are listed as follows: Fixture Standard Shower Heads No more than 2.75 gallons per minute at 80 pounds per square inch of pressure. Lavatory and Sink Faucets No more than 2.2 gallons per minute at 60 pounds per And Aerators square inch of pressure. Wall Mounted, Flushometer No more than 2.0 gallons per flush. Toilets All Other Toilets No more than 1.6 gallons per flush. Urinals No more than 1.0 gallons per flush. Drinking Water Fountains Must be self closing. The City has incorporated these standards into its local plumbing codes. 8of13 Drought Contingency Pian I. Introduction Drought, or a number of other uncontrollable circumstances, can disrupt the normal operation of the City of Port Arthur's water supply system, including supply, treatment, storage and distribution. Even though the City may have an adequate water supply, this supply could become contaminated or a disaster could destroy all or a portion of the water system, creating an emergency management situation for the City. The Drought Contingency Plan includes those temporary measures that the City can utilize to significantly reduce water use in response to an emergency. These measures generally involve voluntary use reductions. They also may include the restriction or elimination of certain types of water use, and water rationing. Because emergency conditions are often unexpected, it is important that the City be prepared in advance. The purpose of the Drought Contingency Plan is to establish measures and procedures for identification, classification, and handling a water supply and/or demand emergency effectively and efficiently. It is important to understand the differences between the Water Conservation Plan and the Drought Contingency Plan. The Water Conservation plan involves implementing and practicing permanent water use efficiency, while the Drought Contingency Plan establishes temporary methods designed to be used during emergency situations. This plan wilt be reviewed and updated every five (5) years. It. Trigger Conditions The City of Port Arthur receives its water from the LNVA. Upon notification from the LNVA, or the Deep East Texas Regional Planning Group, that the water supply is, or will be, 9of13 limited, or a determination is made that the demand is excessive, the City will classify the situation into one of the following condition levels. These condition levels have been established to distinguish between the severity of the trigger conditions, such as mild, moderate and severe. A. Mild Conditions The trigger conditions that will indicate mild conditions are as follows: 1. Notification from LNVA that a mild water storage condition exists. 2. Water demand has reached or exceeded 90 percent of the safe capacity of the City's water plant or distribution system. B. Moderate Conditions The trigger conditions that will indicate moderate conditions are as follows: 1. Notification from LNVA that moderate water storage conditions exist. 2. Water demand has reached or exceeded 95 percent of the safe capacity of the water treatment plant beyond which failure of a part of the system could cause serious disruption of service to a portion, or all, of the City. 3. Contamination of LNVA Canal which requires use of the City's reservoir onl for raw water. C. Severe Conditions The trigger conditions that will indicate severe conditions are as follows: 1. Notification from LNVA that severe water storage conditions exist. 2. An imminent or actual failure of a major portion of the water supply system, which will cause an immediate health or safety hazard. 3. Water system capacity in the distribution system is low enough that sufficient fire fighting capabilities are hindered. 4. Continued contamination of the LNVA source such that our reservoir level is below 50 percent of its useful capacity. 10 of 13 III. Drought Contingency Measures The following actions will be taken by the City according to the level of trigger conditions reached. A. Mild Condition Measures 1. Inform the customers through the mail and by posting the information on the government television channel that a trigger condition has been reached and that the water users should look for ways to voluntarily reduce water use. 2. During winter months, request through the news media thatwater users insulate pipes rather than running water to prevent frozen pipes. 3. Advertise through the news media a voluntary daily lawn watering schedule. B. Moderate Condition Measures 1. Continue all relevant measures from the preceding condition. 2. Notify major water users by telephone of the situation and request voluntary water use reductions. 3. Implement a mandatory lawn watering schedule. 4. Request industries or other non-municipal water users to stop certain uses, find alternative sources, increase recycling, or modify production processes where possible. C. Severe Condition Measures 1. Continue all relevant measures from the preceding conditions. 2. Inform the public through the news media that a severe condition has been reached and that the water users should look for ways to reduce water use. 3. Prohibit the watering of lawns. 4. Prohibit certain uses such as ornamental fountains or other non-essential water uses. 5. Prohibit the filling or refilling of residential swimming pools. 6. Require industrial or commercial water users to stop operations so that remaining water is available for essential health and safety related uses. 11 of 13 The lawn watering schedule will be based on street addresses. Odd numbered street addresses will be allowed to water on odd numbered calendar days, while even numbered street addresses will be allowed to water their lawns on even numbered days. The average increase in water consumption between winter and summer is 22 gpcd. The goal for the voluntary measures (mild drought conditions) is to reduce this by 50% or 11 gpcd. The goal for the moderate drought conditions is to reduce this by 75% or 16 gpcd. For severe conditions, the goal is to eliminate the difference between winter and summer usages. IV. Education and Information The City of Port Arthur will inform the public of the purpose and effect of the Drought Contingency Plan and of the expectations of them during a drought condition or emergency situation. When trigger conditions appear to be approaching, the public will be notified through available news media and additional information on water conservation methods will be distributed. In the event that trigger conditions are reached, the public will be kept fully informed of the status of the drought condition or emergency situation. V. Variances The City Manager, or hislher designee, may, in writing, grant a temporary variance to the policies provided by this plan if it is determined that failure to grant such variance would cause an emergency condition adversely affecting the public health, welfare, or safety, and if one or more of the following conditions is met: A. Compliance with the plan cannot be technically accomplished during the duration of the water supply shortage or other condition for which the plan is in effect. B. Alternative methods can be implemented which will achieve the same level of reduction in water use. 12 of 13 Persons requesting an exception from the provisions of this plan shall file a petition for variance with the City Manager. Variances shall be subject to the following conditions: A. Variances granted shall include a time table for compliance. B. Variances granted shall expire when the plan is no longer in effect, unless the petitioner has failed to meet specified requirement, in which case, the variance will be terminated at an earlier time atthe discretion of the City Manager. No variance shall be retroactive or otherwise justify any violation of this plan occurring prior to the issuance of the variation. VI. Termination Notification Termination of the drought conditions or emergency situation measures will take place when the trigger conditions which initiated the drought contingency measures have subsided. The public will be informed by the City of Port Arthur of the termination in the same manner in which they were informed of the initiation procedures. VII. Implementation/Enforcement The City of Port Arthur Code of Ordinances authorizes the City Manager to develop, implement and enforce this plan, including the provisions in Section 110-70, "Discontinuance of Service°, which provides for termination of service for any consumer violating or permitting violation from his attachments of any of the utility operations department's rules and regulations governing the introduction, supply and consumption of water. Further, the City Council passed Ordinance No. 09-_ on August 25, 2009, adding Code of Ordinances Section 110-34(d) and providing for fines of up to $2,000, or the maximum allowed bylaw-whichever is greater, for failures to comply with City's Water Conservation and Drought Contingency Plans. 13 of 13
