The purpose of the audit was to evaluate the cost effectiveness of installing these <br />VFDs at swimming pools countywide. <br />hi 2006, the Department of Parks & Recreation (P&R) began taking proactive cost savings measures by installing <br />VFDs at three of its swimming pools. However, P&R has not had program objectives for reducing costs since <br />Fiscal Year 2012-2013 and has not installed VFDs at any of the remaining pools. By installing VFDs, we <br />estimate the County could annually save approximately $122,578 in electricity costs. Furthermore, the County <br />should recoup installation costs within the first three years. After this point, all electrical cost savings are in favor <br />of the County. <br />If you need any further information, please let me know. We would like to thank the Department of Parks and <br />Recreation staff for their assistance and cooperation during this audit. We greatly appreciate all of their valuable <br />time and efforts spent on providing us information. <br />Respectfully, <br />Bonnie S. Nims, CGAP <br />Legislative Auditor <br />cc: William P.
