APPENDIX D: POLICY BASELINE AND DEVELOPMENT

groundwater made up 21 percent of the total water production with the other 79 percent coming from the SWTP. The City operates and maintains six wells as follows:

· Two wells at the Spring Lake Pump Station · One well each at the following facilities: · Comanche · McCarty · Soyars · Kingswood

It should be noted that since completion of the 2016 WMP, the two wells at the Oakridge Pump Station have been decommissioned due to influences of surface water and lack of available treatment. The City of San Marcos is part of the Alliance Regional Water Authority , established in 2007. Alliance Water is a Regional Water Authority that was formed for the purpose of resolving the long-term water needs of its participants amongst growing population growth. Alliance Water is comprised of the cities of Kyle, San Marcos and Buda, along with the Canyon Regional Water Authority which represents County Line Special Utility District (SUD), Crystal Clear SUD, Martindale WSC, and Green Valley SUD. Alliance Water developed the Carrizo-Wilcox Aquifer project in 2015 to provide another water source for San Marcos. The project includes the construction of underground pipeline, wells, a water treatment plant, storage tanks, and pump stations to deliver the water.

The City Wastewater Master Plan is to add capacity to the existing wastewater service area and extend infrastructure to new service areas in an efficient and cost-effective manner. The City of San Marcos’s wastewater collection system consists of a network of 219 miles of collector mains, interceptors, and force mains, 40 lift stations, and a wastewater treatment plant along the San Marcos River. Lift stations are necessary when wastewater needs to be pumped to a higher

elevation where the flow can resume flowing by gravity to the outfall of the system. Due to the varying topography, San Marcos operates 40 lift stations and 27 miles of force main throughout the service area.
