This building was constructed to house an electrically powered pump that sent water to an elevated storage tower. The building has metal casement windows on two sides and is roofed with red and green clay barrel tile. A plaque on the building reads, “City Water Board, Brackenridge Park Electric Pump Station #3, March 1940, Conrad A. Goeth, Chair, Lamar G. Seeligson, Martin C. Giesecke, James A. Gallagher, Maury Maverick, Mayor.” The water works channel, which goes underground, originally carried water to power the adjacent pump house (see No. 10). The bridge over the acequia channel has an arched railing of concrete and stone while the bridge over the water works channel has a stone rail on the north side and no railing on the south side.
