This workshop focused on emerging water reuse technologies, success stories regarding implementation of water reuse strategies and technologies, and review of regulatory impediments and incentives for water reuse. Most of the presentations and discussion took place around three key issues: regulations, technology and public relations/outreach. More clearly defined and timely regulations will improve the understanding of water reuse and allow for more efficient water use. Advancing technology will improve the public’s perception about water reuse and will make reuse more economically practical. Outreach is and education is essential to gaining the public’s support of water reuse, which would be a key driver in having more companies and municipalities adopt it.
Session topics:
- Regulatory and Economic Drivers
