From the South Fork Dam, the water supply travels through parallel pipelines. The smaller of the two (a 750 mm diameter steel pipe) was constructed in 1954 and supplies up to 50,000 cubic metres of water per day. As demand increased, a second larger pipeline (a 1,200 mm diameter steel pipe) was constructed in sections, on an as-needed basis. Completed in 1993, this pipeline increased the volume capacity to 240,000 cubic metres per day.
