Drought Contingency Plan-LPAWA 2009.doc <br /> LA PORTE AREA WATER AUTHORITY <br /> DROUGHT CONTINGENCY PLAN <br /> A. INTRODUCTION <br /> Drought, or a number of other uncontrollable circumstances, can disrupt the normal availability of <br /> community or utility water supplies. Even though a city 'may have an adequate water supply, the <br /> supply could become contaminated, or a disaster could destroy the supply. During drought periods, <br /> consumer demand is often significantly higher than normal. Some older systems, or systems serving <br /> rapidly growing areas, may not have the capacity to meet higher than average demands without <br /> system failure or other unwanted consequences. System treatment, storage, or distribution failures <br /> can also present a city or utility with an emergency demand management situation. <br /> It is important to distinguish drought contingency planning from water conservation planning. While <br /> water conservation involves implementing permanent water use efficiency or reuse practices, drought <br /> contingency plans establish temporary methods or techniques designed to be used only as long as an <br /> emergency exists. <br /> An effective drought contingency plan will need to include the following six elements: <br /> 1. Trigger Conditions signaling the start of an emergency period; <br /> 2. Drought contingency measures; <br /> 3. Information and education; <br /> 4. Initiation procedures; <br /> 5. Termination notification actions; and <br /> 6. Means of implementation. <br /> B. SYSTEM CONSTRAINTS <br /> The La Porte Area Water Authority is composed of three(3)entities-the cities of La Porte,Morgan's <br /> Point, and Shoreacres. The Authority purchased production capacity from the City of Houston's <br /> Southeast Water Purification Plant. In addition, the Authority purchased pumping capacity, or <br /> peaking capacity, at.1.25 times the production capacity. Listed below is the production and pumping <br /> capacity for each entity,together with total capacity'. <br /> -CUSTOMER PRODUCTION PUMPING <br /> CAPACITY CAPACITY <br /> (MGD) (MGD) <br /> La Porte 6.302 7.879 <br /> Morgan's Point . 0.555 0.694 <br /> Shoreacres 0.343 0.429 <br /> TOTAL 7.20 9.000 <br /> 2001 Capacity Figures <br /> Page 1 of 5 <br />
