For compliance with the Sustainable Sites Credit, Site Management, when submetering of the

irrigation system is not available or difficult to implement for an existing building, the recommended

strategy is to use automated leak detection systems, such as those that use pressure sensors. The

guidance for irrigation management under the LEED for Operations and Maintenance (O+M) rating

system includes monitoring irrigation systems manually or with automated systems at least every

two weeks during the operating season for appropriate water usage, system times, leaks, or breaks.

Automated systems, particularly those employing pressure sensors, are effective in detecting leaks

and irregularities in water use, thereby contributing to efficient water management and

maintenance of the irrigation system. Reference: LEED v5 O+M: Existing Buildings beta version
