Yesterday the President and the Democrats agreed to work on a plan to spend $2 Trillion on badly needed green (and other) infrastructure projects. We know that if it were ever to happen, there would be more worthwhile projects than money to pay for them. Currently, the American Society of Civil Engineers estimates that there is a $105 million funding gap for water infrastructure repairs and replacements around the country. How can that funding go farther? Some cities have pioneered new cost-cutting water infrastructure technology that does not compromise on water quality and public safety. South Bend, Indiana and Kansas City, Missouri have used a high tech system developed from military technology to make their sewers “smarter” through digital water data monitoring and collection, and adaptive operations based on that data.
Using funds provided by the Obama Administration for “smart cities,” Mayor Pete Buttigieg partnered with a group of researchers at Notre Dame to implement a smart sewer system with 150 wi-fi enabled sensors throughout the city to detect rising water levels and re-direct water flow – which they were able to complete in 2017 at a cost of only $150 million.
Phase 2 is expected to cost $700-million but the city says data from the smart system helped them develop a new plan that will cost only $200-million, slashing the overall cost by $500 million, but it is awaiting EPA approval.
Since 2010, the city has spent $505 million to prevent combined sewer overflows from entering the Missouri River. In all, the city said expected to spend $2.5 billion over 25 years to meet the EPA requirements under the Clean Water Act.
Kansas City installed smart sewer and stormwater systems to reduce overflows into the river and they believe resulting cost savings – estimated at $1 billion –due to IoT, AI, and data mining – this technology should be a model for other cities.
Why This Matters: Unleashing the power of technology could save the U.S. billions and make our limited infrastructure funds go farther. What we need is leadership and vision, and a willingness to try new things. South Bend’s wastewater transformation happened under the leadership of Mayor Pete Buttigieg. Could he do the same for aging infrastructure all over the country? The South Bend sewer system — as smart as it is — failed during a massive 500-year flood in 2018. Which is why infrastructure updates need to be made to withstand the climate disasters of the future — just as Beto O’Rourke proposed in his climate plan rolled out on Monday. Any infrastructure plan passed by Congress must be sustainable or we will waste precious money.
by Jessica Grannis We’re in the dog days of summer now, and lots of folks are headed to the beach to make up for lost time since the pandemic began. My favorite part of traveling to the coast from DC is watching my surroundings slowly turn from urban areas to the forests of the coastal […]
By Ashira Morris, ODP Staff Writer The West is currently in the middle of a severe drought, and Lake Powell, the region’s second-largest reservoir, is at its lowest level in decades. The lake, located on the Colorado River, is effectively a human-made storage basin that keeps the regional water supply in balance under the 100-year-old […]
by Amy Lupica, ODP Staff Writer Ongoing heatwaves and mega-drought across the Western U.S. threatened residents with rolling blackouts and even buckling roads. Now, rapidly rising temperatures are taking their toll on renewable energy infrastructure as well. After suffering some of the lowest rainfall rates in 126 years, Northern California’s Edward Hyatt hydroelectric power plant is predicted to shut down for […]
