The Metropolitan Sewer District of Greater Cincinnati (MSDGC), a wastewater operator providing collection and treatment services to more than 800,0000 residents in Cincinnati, Ohio, operates a combined sewer system. Every year, MSDGC discharged about 11B gallons of combined sewage into the Ohio River.

Sewer District of Greater Cincinnati (MSDGC) Case Study

EXECUTIVE SUMMARY

When Metropolitan Sewer District of Greater Cincinnati needed to comply with an EPA consent decree, they engaged Ayyeka to create the most cost-effective solution while utilizing and controlling existing systems (rather than starting from scratch.)

PROJECT SCOPE & RESULTS
✔️1,000+ level, flow, rain, and wastewater quality Wavelet remote monitoring kits that form the telemetry backbone of the wet weather SCADA project.

✔️Installed 1,000+ measurement points.

✔️Enabled real-time network visibility.

✔️Reduced overflows by leveraging data brought from Wavelets to SCADA to optimize control of existing infrastructure.

✔️Data analytics enabling smart sewer with overflow forecast.

✔️Reducing the cost of reducing sewer overflow discharge from $1/gallon to $0.01/gallon (99% cost reduction).

The Metropolitan Sewer District of Greater Cincinnati (MSDGC), a wastewater operator providing collection and treatment services to more than 800,0000 residents in Cincinnati, Ohio, operates a combined sewer system. Every year, MSDGC discharged about 11B gallons of combined sewage into the Ohio River.


Before implementing Ayyeka’s technology, MSDGC utilized several hundred CSO dataloggers. Data that was collected and stored in these devices was downloaded intermittently by crews that were deployed to change batteries and check operational parameters. 

Connecting the entire collection system to the MSDGC’s SCADA system enabled the teams to develop predictive models to assess the impact of precipitation events in the various catchment areas throughout its collection system. As a result, MSDGC substantially reduced the number and severity of overflow events and move toward regulatory compliance.
