First Water Works Pump House - Brackenridge Park - San Antonio, TX - NRHP Historic Districts - Contributing Buildings on Waymarking.com

"The one-story pump house stands to the right of the bridge. Designed to raise water to a reservoir approximately one mile southeast (beyond the park boundaries), the building is constructed of smooth-finished, cut limestone extracted from the city rock quarry a short distance to the south. Arches over doors and windows are of rusticated stone with central keystones. The low hipped roof is covered with corrugated metal. Tall wooden doors are set in the central entrance arch and there are double-hung wood sash windows on all elevations. A center column and beam support the pump house as it spans the river. The raceway exits into the river on the south side of the building. Stone rubble wing walls curve from the building along the river. The interior space is not partitioned and possibly was used as an office for the Water Works. This pump house is the oldest intact industrial building remaining in San Antonio."
