EPA’s Point of View
1. Communities will save millions by maximizing their existing infrastructure
2. Real Time Control is a technology that maximizes infrastructure
3. 2004 Report to Congress on CSO and SSO Impact reports on Real Time Control technology
4. Real Time Control satisfies 4 of EPA’s CSO 9 minimum Controls

Maximize Use of Infrastructure
Use in-line storage capacity
Maximize inflows to WWTP
Control flows according to rain distribution
Flow at WWTP1-month event
