For the commercial users, the audit included characterizing indoor and related water use (including process water and car wash use), such that outdoor water patterns could be understood and characterized. For the irrigation accounts, where the specified taps were dedicated to only outdoor water use, the interactive portion of the audit focused on understanding the location of the tap and the ongoing nature of the irrigation effort, including determination of irrigation equipment, sensors and control measures. Unfortunately, many of those with identified water accounts were not amiable to the audits even though they were provided free of charge. The large retail houses (i.e., Target and Safeway) refused to allow access to the property in question. Other entities such as Jenny's Market (formerly BP Products), Escavera, Douglas County Maintenance (related to the Douglas County Jail), the Players Club Villas Homeowners Association (HOA) (related to Apricot Pool), and numerous contracted irrigators did not return numerous phone calls and/or provide information in a timely fashion that would have aided the audit process. Nonetheless, a review of all nineteen water accounts was performed using the available information. Please make note of the attachments that are relevant to this section as noted below: .
