The District’s Water Supply and Water Conservation Management Plan Water Conservation Action No. 9 requires water providers to offer commercial, industrial, and institutional water audits to its customers. The assessment includes the development of a report that provides guidance on how to reduce water usage by outlining possible changes to processes and operations.
Industrial Commercial and Institutional (ICI) uses are variable and complex. Examples of types of facilities may include, but are not limited to, commercial and retail centers, office buildings, hotels and motels, coin and card operated laundries, auto service and repair shops, restaurants and fast food, bakery and pastry shops, beverage manufacturers, commercial printers, fuel service stations and convenience stores, vehicle washes, schools, grocers, hospitals, industrial bakers, industrial laundries and dry cleaners, laboratories, metal finishers, and paper manufacturers. A facility’s water use can be related to those they serve, such as industrial processes, number of hotel customers, students at a school or patients at a hospital. Different types of facilities will have different water-use characteristics and potential efficiencies; however, this may also vary within the same type of facility. Therefore, an on-site water audit of a facility provides a more accurate assessment than estimating efficiencies of certain types of facilities. Commercial water audits include a site visit, characterization of existing water uses, and recommended changes to process and operations to reduce water usage.
