Situation

May 2009 hurricane caused flooding damage in excess of $50M.

Results

• $7.8M in savings by upgrading existing pumps with Opti’s automated forecast based controls
• No flooding at Central Park Lakes during Hurricane Irma (2017) and Dorian (2019)

Situation

Over 530 million gallons of combined sewer overflows (CSOs) annually and flash flooding causing infrastructure damage and public safety and health concerns.

Results

• 93% capital savings with Opti’s Smart Watershed Network Management and active control implementations on new and existing upstream storage infrastructure
• 6.5X improvement in wet weather capture mitigating downstream flooding and CSOs

Situation

27 billion gallons of combined sewer overflows into NY Harbor per year.

Results

• 87% capital savings with Opti’s rainwater harvesting solution for stormwater capture and water reuse
• 500,000 gallons of rainwater capture

Situation

Frequent flash flooding and EPA CSO consent decree.

Results

• $0.04/gallon wet weather capture vs. >$1.00/gallon with passive controls
• 59-84% annual wet weather capture
• Real-time controls as a requirement for property development

Situation

Undersized storage and conveyance for two large watersheds that converge under Byrd Drive caused flooding 4-5 times annually, with an average roadway shutdown of 2 hours.

Results

• More than $2.0 million in savings by optimizing upstream detention with Opti’s active controls
• 57% wet weather capture and reduced flood occurrences at Ewart and Byrd intersection

Situation

Catastrophic flooding in Ellicott City during 2016 & 2018 and >2,000 acre water quality restoration requirement under MS4 permit.

Results

• 70% capital savings to manage water quality and quantity with Opti’s active controls
• 72% annual wet weather capture

Situation

Capital Region Water District partners with the City of Roseville and Falcon Heights to improve stormwater management, including water conservation, quality and flood mitigation.

Results

• Elimination of flood occurrences with Opti’s active controls since 2015
• 50lb reduction in annual phosphorus loading into Lake McCarrons each year

Situation

The Maryland Department of Transportation (MDOT) is under regulation to treat runoff from 4,621 acres of impervious cover by October 2020. To help them achieve this goal, Opti and The Nature Conservancy (TNC) formed a joint venture and P3 to retrofit private stormwater ponds across the state.

Results

• 83% or $125,000/acre taxpayer savings compared to traditional approaches
• Private landowner tax credits, corporate sustainability, property flood risk mitigation and improved operations

Situation

Nearly 60 percent of the City's sewers are combined, with more than 11 billion gallons of stormwater and its pollutants discharged into local waterways each year. To address this issue, Philadelphia Water Department (PWD) has implemented Green City, Clean Waters, a comprehensive plan focused on reducing stormwater pollution to the City's sewers with investments in both public green infrastructure projects and private partnerships.

Results

• 80% capital savings by implementing Opti’s active controls on existing private storage facilities
• 90% wet weather capture
