High Rate of FlowGoing downstream (west) along NE Davis, a lateral located 40 feet from the manhole at shows a high rate of flow entering the sewer from the left side. The location coincides with a lateral mapped in the City GIS.

2013: It’s Like Déjà Brew All Over Again

Folk Wisdom

“Fool me once, shame on………shame on you. Fool me…….you can't get fooled again.”- GWB


2007: Pasteurizer Overflow to NE Floor Drain

City: Where does all this flow go?PBC: I don’t know. *shrugs* ¯\_(ツ)_/¯City issues Compliance Order

NE Floor Drain


2007: Compliance Order Requirements

• Inspect sewer connection at NE Floor Drain• Unauthorized connection direct to NE Davis? or

• Other unauthorized connection?

• If discharging via unauthorized connection:A. Plug drain & re-route to existing point of compliance, or

B. Install new sampling manhole along NE Davis lateral

Follow-Up Call About Their Progress• PBC: I don’t know. *shrugs* ¯\_(ツ)_/¯• Surprise Inspection


2008: Dye Inserted at NE Floor Drain

Connection Confirmed• PBC decides against

installing a sampling manhole along NE Davis


2008: Compliance Order Actions

• Plug NE Floor Drain (Mechanical Style: Threaded/Expanding)

• Re-Route to Existing Point of Compliance

• Install Discharge Meter

• Late Compliance Order Report (Minor Enforcement)

Flow Reporting Supports Compliance

• Discharge = 50% of Water Use


2013: Initial Enforcement for Illicit Discharge

• Notice of Violation Class 1 (Major Enforcement - $800)

• Plug NE Floor Drain (Permanent / Concrete)

Before

Drain Open

After

Drain Sealed


2014: Return to Compliance & Follow-Up

• Discharge = 24% of Water Use in 1st Quarter• 24% Identified as “Expected Sewer Use”

Assessment of Long-Term Violations

• Violations Enforced by Extent through Time• $100/day x 966 days + $800/day x 57 days

• Estimate Cost Recovery for Sewer Use• 21 Million Gallons x Base Sewer Rate

• 120 Tons BOD x Custom Rate
