support the efforts of PCCD. The district rules attempt to regulate groundwater bymeans of well spacing based on production rates. Table 4-3 provides a list of thespacing production provisions.TABLE 4-3PCCD Classification, Spacing, and Production ProvisionsActual PumpingCapacity of ProposedWell (GPM)Classification ofProposed WellMinimum Distance fromNewest Existing Well onAuthorized Well SiteLess than 25 GPM Domestic None25 - 100 A 600 Feet101 - 250 B 1,500 Feet251 - 500 C 3,000 Feet501 - 1,000 D 6,000 Feet1,001 GPM and over E 12,000 FeetNote:Wells drilled after December 31, 2003 shall either perform ahydrologic study approved by the District designed to demonstratethe impact of the permitted well on wells located within a one-halfmile radius, or comply with the District's spacing requirements. Wellsare classified according to actual pumping capacity in gallons perminute (GPM) under normal operating conditions.4.3.2 Gonzales County Underground Water Conservation DistrictThe GCUWCD was created on an order of the Texas Natural Resourceconservation Commission number 101692-Do4 and is charged specifically withmanaging the Sparta, Queen City, and the Carrizo-Wilcox aquifers in GonzalesCounty. The goals of the Management Plan and Rules established by the districtare to conserve, preserve, protect and prevent waste for the future of GonzalesCounty.The goals of the district are carried out through the GCUWCD Rules andManagement Plan. The plan defines spacing requirements and pumpingproduction limitation to manage the groundwater. Although the DFC has not been4-11Klotz Associates Project No. 0972.000.000Caldwell County Regional Water and Wastewater Planning StudyJanuary 2010Final Report
developed, a drawdown of 100 feet in the Carrizo will curtail pumping. A list oftables and rules from the PCCD and the GCUWCD has been included inAppendix E.The GCUWCD is also working with other districts in GMA 13 to develop DFCwhich will revise the current Management Plan to reflect the managed availablegroundwater (MAG). The GCUWCD is in the same situation as PCCD withpossible over permitting of the Carrizo-Wilcox Aquifer.In February 2009, the GCUWCD stated that the only permitted public transporterwas the Schertz-Seguin Local Government Corporation (SSLGC) for 12,900 acrefeetper year. The length of the transport permit is 30 years. The SSLGC supplieswater to the cities of Schertz and Seguin. Permits under review were submitted byCRWA and SAWS. Aqua WSC also has wells that were established before thecreation of the GCUWCD and have been grandfathered on the east side ofGonzales County. Those existing wells remain operational under the grandfatherprovision and do not need to adhere to the current rules of the district.Klotz Associates Project No. 0972.000.000January 20104-12Caldwell County Regional Water and Wastewater Planning StudyFinal Report
