Late 1800’s Germ Theory by Koch & Pasteur
1900 Beginning of the Profession
Water Quality linked to Health Risks
Protection of drinking water sources
Major Cities begin development of sanitation
•
Chicago’s Sanitary and Ship Canal
1910 – 20’s Treatment processes developed
Cities start to boom
Higher density creates need for treatment
Constructing sedimentation tanks
•
“get the big stuff out”
1930 – 40’s Treatment advances
January 2011
More growth – more pollution
WPA projects create funding source for POTWs
But Implementation of treatment not uniform
Background
Federal Water Pollution Control Act of 1948
Fox Valley
Operators
Association
First major U.S. law to address water pollution
Enforcement limited to interstate waterways
Each State had its own standards

Planning was not uniform
Collection system designs varied (combined/ separated)
Overflows were common
Level of treatment varied
Water Quality suffered
1960’s the environment becomes a hot issue
Industrial waste dischargers unchecked
Wildlife and Aquatic Life were impacted
Pollution was a common problem
America wasn’t so beautiful
Fox Valley Operators Association was founded

Federal Water Pollution Control Amendments
of 1972 – (CWA of 1972)
Declared most waterways “Waters of the States”
Expanded and strengthened the previous legislation
Established US Environmental Protection Agency
Tasked USEPA with evaluating situation
Gave USEPA the authority to regulate POTW’s
Est. the framework for Water Quality Standards
Established the NPDES Permit System
Established technology based limits
•

Secondary Treatment Standards
Background
Clean Water Act of 1977
Fox Valley

Amended the 1972 legislation
Established Water Quality Standards

Provided federal funds for implementation
Direct Sanitary Sewer Overflows were eliminated
Collection systems were rehabilitated
Infiltration and Inflow was reduced
Combined Systems were often separated
Excess Flow and CSO Treatment Facilities were
constructed

January 2011
Amended Water Quality Standards and procedures
Added regulation of biosolids
MS-4 permit system for storm water
Increased regulation of non-point discharges
Eliminated Grant Funding
Established Revolving Loan Fund
Results
More stringent Water Quality Standards
POTW’s forced to focus on treatment technology
Unfunded mandates equated to increase user rates
Investment into collection system rehab slowed

Discharges that do not meet WQS are in
violation of the Clean Water Act.
CSO’s & SSO’s are a violations of the CWA
Remaining CSO/SSO’s were made top priority.
Regulators pursued enforcement through the
through NPDES permits process.
POTW’s negotiated Compliance Agreements
POTW’s developed and implemented “Long Term
Control Plans”

Focus is shifting to communities with separate
sanitary sewer systems
Sanitary Sewer bypasses have been eliminated
Basement back-ups & sewer overflows still occur
The industry starting looking at why?
•
•
•
•
•
Partly because SSES programs were static
Partly because Funding wasn’t available
Partly because Political will to raise rates didn’t exist
Partly because few measured the successes
Therefore we could not show cause and effect
Last Twenty Years
Water Professionals started seeking success

Unsuccessful SSES Projects
•
Reduction of I/I is not a one time project
POTW’s with annual programs were successful

Proposed Regulation prohibits any discharge
prior to the WWTP
Provides consideration for severe natural causes
•
•
•
POTW must report all SSO’s within 10 ten days
Demonstrate that cause was beyond control of POTW
POTW must take reasonable steps to stop and mitigate
Consequences for failure to comply with CWA
