The City of Boerne’s current water supply is obtained from the Trinity Aquifer and Cibolo Creek at Boerne Lake.  The City of Boerne is projected to need additional water supplies beginning in the year 2000.  The following options were considered to meet the city’s projected need:

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

§         Western Canyon Regional Water Supply Project

§         Purchase Water from Major Provider

Working within the planning criteria established by the SCTRWPG and the TWDB, it is recommended that the City of Boerne implement the following water supply plan to meet the projected need for the city (Table 5.3.14-2).

§         Municipal demand reduction (conservation) to be implemented in 2000.  This project can provide an additional 42 acft/yr of supply in 2000, decreasing to 0 acft/yr in 2030.  (See Section 6, Supplement 2 and Volume III, Section 1.1).

§         Western Canyon Regional Water Supply Project to be implemented in 2000.  This project can provide an additional 1,861 acft/yr of supply beginning in 2000.
