As cities rush to solve major problems with water infrastructure, newer technologies are being touted by city agencies as cheaper, cleaner solutions. In two different local projects, the Metropolitan Sewer District of Greater Cincinnati (MSD) and a City Council task force are looking into green ways to solve the city’s water needs.
On Wednesday, CityBeat covered some of the benefits and downsides of green water infrastructure. According to the report reviewed Wednesday, green water infrastructure is cheaper and does create a boon of jobs, but it faces some funding and education problems. However, it was unclear how the green ideas would translate into Cincinnati.
Tony Parrott, executive director of MSD, says despite the challenges, green infrastructure is clearly the cheaper option. The organization is partnering with local organizations to adopt a series of new projects — among them, green roofs, rain gardens, wetlands — to meet a new federal mandate that requires MSD to reduce the amount of sewer overflow that makes it into local rivers and streams.
“That is a very costly mandate,” he says. “Our belief is that green infrastructure and sustainable infrastructure will allow us to achieve a lot of those objectives a lot cheaper than your conventional deep tunnel systems or other gray type of infrastructure.”
Of course, conventional — or “gray” — infrastructure still has its place, but adopting a hybrid of green and gray infrastructure or just green infrastructure in some areas was found to be cheaper in MSD analyses, according to Parrott.
Plans are already being executed. On top of the smaller projects that slow the flow of storm water into sewer systems, MSD is also taking what Parrott calls a “large-scale approach to resurrect or daylight former streams and creeks that were buried over 150 years ago.” This approach will rely on the new waterways to redirect storm water so it doesn’t threaten to flood sewers and cause sewer overflow, Parrott says.
The programs are being approached in a “holistic way,” according to Parrott. MSD intends to refine and reiterate on what works as the programs develop. However, that comes with challenges when setting goals and asking for funding.
“We think that if you’re going to use a more integrated approach, it may require us to ask for more time to get some of these projects done and in the ground and then see how effective they are,” Parrott says.
If it all plays out, the ongoing maintenance required by the green approach could be good for the local economy, according to Parrott: “With the green and sustainable infrastructure, you’re creating a new class of what we call green jobs for maintenance. The majority of those jobs are something local folks can do as opposed to the conventional process.” Additionally, the green jobs also tend to benefit “disadvantaged communities” more than conventional jobs, according to Parrott.
The argument is essentially what Jeremy Hays,chief strategist for state and local initiatives at Green For All, told CityBeat on Wednesday. Since the green jobs require less education and training, they’re more accessible to “disadvantaged workers,” according to Hays: “They require some training and some skills, but not four years’ worth because it’s skills that you can get at a community college or even on the job.”
While MSD fully encourages the use of rain barrels, recycling will not be a top priority for MSD’s programs. Instead, that priority goes to the Rainwater Harvesting Task Force, a City Council task force intended to find ways to reform the city’s plumbing code to make harvesting and recycling rainwater a possibility.
Bob Knight, a member of the task force, says there is already a model in place the city can use. The task force is looking into adopting the International Green Construction Code (IGCC) in Cincinnati. The code will “prescriptively tell” architects and engineers how to design a rainwater harvesting system. In other words, IGCC would set a standard for the city.
Deciding on this code was not without challenges. At first, the task force wasn’t even sure if it could dictate how rainwater is harvested and recycled. The first question Knight had to ask was, “Who has that authority?” What it found is a mix of local agencies — Greater Cincinnati Water Works, MSD and Cincinnati Department of Planning — will all have to work together to implement the city’s new code.
The task force hopes to give its findings to Quality of Life Committee, which is led by Vice Mayor Roxanne Qualls, by the end of November.
