HISTORY OF THE SAN ANTONIO WATER SYSTEM San Antonio has always relied upon the Edwards Aquifer for its water supply. The Edwards feeds the San Pedro and San Antonio springs that, until the middle of the 20th Century, provided the base flow for the San Pedro Creek and the San Antonio River. The springs were the site of Indian encampments centuries ago and were the reason that the Spanish established San Antonio in 1718. The primary water distribution system in the area was the acequías, or community water ditches. The first ditch, Pajalache or Concepcíon Ditch, became operational about 1720. The acequías were supplemented by shallow wells and provided water for both irrigation and consumption. These ditches also began to serve as a de facto sewer system. Early San Antonians merely deposited their garbage and other wastes into the ditches where they were carried downstream. In 1836, the San Pedro Ditch was reserved for drinking and cooking water only; penalties were established for using it for bathing or as a sewer. Although crude, this water and wastewater operation served the City's needs until 1866 when a severe cholera epidemic prompted real efforts to establish a satisfactory water supply system. Many water development proposals were discussed and subsequently discarded over the years until the City finally entered into a water supply contract with J.B. LaCoste and Associates on April 3, 1877. LaCoste constructed a pumphouse near the headwaters of the San Antonio River in what is now Brackenridge Park. Water pressure operated a pump that lifted water to a reservoir near the old Austin highway on the present site of the Botanical Gardens. This site was high enough for the water to flow by gravity into the distribution system. In 1883 a new company, led by George W. Brackenridge, acquired the water system. Recognizing that the source of the springs was possibly a subterranean reservoir under high pressure, Brackenridge proposed that his firm purchase property along the river and drill a well. In 1889, the first artesian well was bored in what later became Brackenridge Park. Two years later an eight-inch discovery well was drilled to a depth of 890 feet at Market Street and the San Antonio River. By 1900, all of the system's water was obtained from artesian wells linked directly to the distribution system. In 1905, George Brackenridge sold his interests in the Water Company to George Kobusch of St. Louis. At that time the name was changed to the San Antonio Water Supply Company. Shortly thereafter, Mr. Kobusch sold the business to a Belgian syndicate. While it was under foreign ownership, the water company was known as "Compagnie des Eaux de San Antonio" and was managed by the Mississippi Valley Trust Company of St. Louis, Missouri. Partly to recover some of their financial losses from World War I, the Belgians sold the waterworks to a group of local investors in 1920. Contract and rate disagreements marred the relationship between the City and
