Flooding Update from Dawn Zimmer
4th Ward Councilwoman Dawn Zimmer provided this press release, updating what’s going on with the flooding in Hoboken:
Cutting Edge Technology to be introduced tonight
Last Friday North Hudson Sewerage Authority announced that it would proceed with only one of the four wet weather pumping stations that it believes Hoboken needs to fully address its flooding issue. Fortunately, the pump that will be built, at NHSA’s $14 million expense, will be located in the southeastern section of town. This is the most critical pump for the neighborhoods most impacted by the flooding.
The previous plan involved building this most important pump last, which would have taken at least 4 – 6 years to be installed. I want to thank North Hudson sewerage for correctly prioritizing the Southeastern pump. The additional 3 pumps, which would cost as much as $30 million and would be paid for entirely by Hoboken, have been put on hold presumably as a result of Hoboken’s financial difficulties.
This may be a blessing in disguise because it is possible that the 4-pump plan can be revised to be both more effective and more economical. Real-time control technology developed by EmNet LLC could help Hoboken make the Southeastern pump that NHSA has committed to build more effective, bringing us faster relief from our flooding problem. Depending on what is learned from the data, the technology could also potentially allow us to ultimately relieve our flooding problem with fewer than the 4 pumps suggested by NHSA, saving Hoboken millions of dollars as compared to the original 4-pump plan. EmNet has conducted a complete review of the proposed 4-pump plan, including an on-site evaluation of Hoboken’s sewer system. They will present their findings and introduce their technology and proposed solutions at tonight’s City Council meeting during new business.
See the rest, plus comprehensive reports – after the jump!!
(Hoboken Flooding Update, Continued…)
EmNet’s real-time control technology could help us determine the fastest, most effective and most economical action plan possible. Hoboken’s existing pump plan is based on what’s known as a SWMM model, which has an error rating of up to 20 percent. EmNet’s wireless CSO technology greatly reduces that error margin by monitoring exactly what’s happening in the sewer system. It uses sensors that can easily be installed under manhole covers and on utility poles.
EmNet LLC teamed with the University of Notre Dame, and Purdue University to develop its real-time control monitoring system. Through the 21st Century Fund, created by the State of Indiana to support innovative high tech companies, they have received over $2 million in funding for their wireless technology. Mayor Luecke of South Bend, Indiana, credits EmNet’s technology with helping his City to reduce the costs for solving their flood problem by more than $100 million. Ed Freidrich, a Hoboken resident committed to helping find a solution to our flooding, conducted research to learn about EmNet, and brought the technology to my attention.
CH2MHill, the consultant that designed the pump plan, and other experts, have advised me that Hoboken will eventually be required to integrate its pumps with a system to stop pumping our combined sewer overflows into the Hudson River. According to NHSA the future cost for preventing CSO’s could be astronomical. We’ve got to start creating an integrated plan now to deal with future costs, rather than waiting for the crisis when state and federal agencies enforce the Clean Water Act.
Most importantly, we’ve got to do everything we can to reduce the amount of storm water entering our sewer system. Green infrastructure, such as green roofs, and tree pits with water storage chambers, must be an integral part of the solution. I am proposing, and searching for funding, to do a citywide evaluation of the potential for green technology to alleviate the flooding. EmNet’s technology will give us the tools to determine the effectiveness of future green technology projects, and the data will also enable us to get ahead of the curve and aggressively pursue upcoming funding opportunities.
