Commercial coin-operated laundry installations pose problems when sewers are not available, and septic tank or leach field systems are utilized. Because of the small amount of land available for liquid waste discharge, additional treatment is necessary. Treated effluent reuse should also be considered.
Table 8.1.3 indicates typical waste flow (Flynn and Andres 1963) from laundry installations on Long Island, N.Y. A typical installation of 20 machines produces 4,000 gpd. Depending on soil conditions, this volume might require a much larger disposal area than is available. Table 8.1.4 describes typical laundry waste properties and composition as resembling weak sewage with the exception of high alkyl benzyl sulfonate (ABS) and phosphate contents.
Large quantities of water are required for washing, therefore alleviating both water supply and waste disposal
