water or groundwater to meet future water supply needs. Redundancy in watersources is an important part of a long-term water supply plan to buffer impactsfrom droughts, aquifer management rules and potential pollutant contamination ofwater sources.Exhibit 16-1 presents the features of the recommended regional water supplyplan. The primary features include:• River pumping plant with dam to create pumping pool in GuadalupeRiver for scalping flood flows• Off-channel storage reservoir near river pumping plant to provide waterdelivery system water balance• Carrizo Aquifer Well Field in southern Caldwell/northeastern GonzalesCounties• Pipeline (approximately 18 miles) to convey raw surface water from offchannelstorage reservoir to Luling• New surface water treatment plant at Luling• Pipeline (approximately 21 miles) to convey unchlorinated groundwaterfrom Carrizo well field to Lockhart• New groundwater treatment plant at Lockhart• Pipeline (approximately 12 miles) to convey treated water north fromLockhart along SH 130• Pipeline (approximately 10 miles) to convey treated water west fromLockhart along SH 130• Pipeline (approximately 7 miles) to convey treated water north fromLockhart along FM 2720• Use existing pipeline from Lockhart to Luling to move water in eitherdirection as demands and supplies are balancedThe majority of the stakeholders attending the regional planning meetingssupported either the proposed Mid-Basin Project or the HCPUA Project.
