What Does a CWEP Do?

Water efficiency professionals are often energy managers that have selected to focus on, or expand into the specific area of water management. This may include improving water usage and efficiency in an existing building or implementing a sustainability program that includes water efficiency for their firm or organization. These individuals will understand water systems and technologies and will have specific knowledge on utility billing practices, and policies, incentives, and water specific mandates made by local municipalities, federal, or state governments. They use their specialized knowledge to assist firms or organizations, they audit existing systems, set realistic goals for new projects and get the most significant benefits when implementing systems at a small or large scale.
