*Well Spacing*	Wells shall not be located closer than 100' to the property line. Spacing of new wells from an existing well shall be one foot per 1 gallon per minute of production. Domestic and Livestock wells and wells producing less than 25,000 gallons per day are exempt from these rules.
*Production Regulations*	Production may not exceed 652,000 gallons (2.0 acre feet) per acre per year.

*NPS and Point Source Regulations*	The District has regulations for: well spacing from sewage facilities; livestock yards and flood prone areas; well completion standards; well plugging and capping requirements and permitting of recharge wells. The District has worked with the TCEQ to promote well head protection.
*PROGRAMS*
Public Education	The District educates through audiovisual, educational programs, reference material collection, public service announcements on local radio stations, booths at local fairs, speaker programs and public information meetings.
*Special Activities*	The District has an Agricultural Water Conservation Program. Through loans from the Texas Water Development Board, low interest loans are offered for the purchase of water conserving low pressure irrigation systems. The District participates in a ten-county weather modification program that is designed to enhance precipitation in the District in order to increase groundwater recharge and conserve existing groundwater resources. The program owns and operates a radar and four cloud seeding aircraft, with the radar and two of the aircraft located in Pleasanton, one in Kendy, and the forth at Stinson Field in San Antonio. The evaluation of the 2000-2001 Precipitation Enhancement Program indicated that an additional 62,908 acre/feet of rainwater was produced by cloud seeding. If a conservatively estimated 60% of the rainwater reached the ground, the additional water produced would have cost $5.43 per acre/foot.
