Using Real Time Control to Maximize Your Existing Infrastructure

Dr. Hubert Colas, Executive Vice President

2

Context of Wastewater Regulations

• Billions of dollar in new investments required for:– Combined Sewer Overflow (CSO) Control ($ 50 billion)– Sanitary Sewer Overflow (SSO) Control ($ 88 billion)– Capacity, Management, Operation and Maintenance

(CMOM)– Blending Policy, – Etc.

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
