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 <br />PRODUCTION CAPACITY(MGD) <br />PUMPING CAPACITY(MGD) <br />La Porte <br />6.925 <br />8.65625 <br />Morgan's Point <br />0.550 <br />0.68750 <br />Shoreacres <br />0.325 <br />0.40625 <br />TOTAL <br />7.800 <br />9.75000 <br />In addition, each entity has the ability to supply its entire water supply through groundwater <br />production from wells. After 1990, the Harris -Galveston Coastal Subsidence District decreed that <br />no more than ten per cent (10%) of each entity's yearly water production can be produced from <br />groundwater. Although additional pumping capacity is planned for peak purposes, groundwater <br />production will be utilized for peaking purposes whenever possible. <br />Temporary reductions or disruptions in surface water supply can be offset by increased groundwater <br />withdrawals. Careful monitoring and management of groundwater withdrawal is necessary to avoid <br />exceeding the yearly ten percent (10%) limit. <br />Long-term reductions or disruptions in surface water supply would require special permission from <br />the Harris -Galveston Coastal Subsidence District to exceed allowable groundwater withdrawal. It is <br />anticipated that conservation measures would be required by the Harris -Galveston Coastal <br />Subsidence District to allow increased groundwater withdrawal. <br />The City Manager or his/her designee shall monitor water supply and demand conditions on a weekly <br />basis and shall determine when conditions warrant initiation or termination of each stage of the Plan. <br />The trigger conditions described below reflect system capacity limits and are based on a seven (7) day <br />average daily demand and include the permitted withdrawal of groundwater. <br />1. Mild Conditions (Staee 1) <br />a. Water demand approaching 6,665,000 gallons/day(70% of the pumping capacity owned <br />by the Authority at the Southeast Water Purification Plant plus allowed groundwater <br />withdrawal). <br />Or, <br />b. Production at the Southeast Water Purification Plant reduced to a point such that the <br />aggregate surface water demand of the Authority is 70% of the reduced pumping <br />capacity. <br />c. Stage 1 may be rescinded when the trigger conditions have ceased to exist. Rescinding <br />any level of the Plan is at the discretion of the City Manager. <br />2. Moderate Conditions (Stage 21 <br />
