5.3.20.1   City of Floresville

The City of Floresville’s current water supply is obtained from the Carrizo Aquifer.  The City of Floresville is projected to need additional water supplies beginning in the planning year 2040.  The following options were considered to meet the city’s projected need:

§         Demand Reduction (Conservation) (L-10 Mun.)

§         Carrizo Aquifer – Local Supply (SCTN-2a)

Working within the planning criteria established by the SCTRWPG and the TWDB, it is recommended that the City of Floresville implement the following water supply plan to meet the projected need for the city (Table 5.3.20-2).

§         Municipal demand reduction (conservation) to be implemented in 2000.  This project can provide an additional 101 acft/yr of supply in 2000, decreasing to 75 acft/yr of additional supply in 2050. (See Section 6, Supplement 2 and Volume III, Section 1.1).

§         Carrizo Aquifer – Local Supply (SCTN-2a) to be implemented in 2040.  This project can provide an additional 200 acft/yr of supply in 2040 and 2050.
