Louisville Builds a Mega Sewer to Reduce Overflows

Louisville has an extensive sewer system and the city has been obliged to bring their sewer systems up to date in order to withstand the occurrences of heavy rain events. In the recent past, storms have produced overflows and conditions that have precluded this required obligation. Nearby residents can expect ongoing construction of a high-tech, massive tunnel system complete with a 20 million gallon sewage storage basin designed to sharply reduce bacteria-laden overflows into the Ohio River. All of the construction in process will necessitate some of the area parks, specifically Shawnee Park, to be unavailable for months to come. Nearby roadways will also limited thoroughfare during this time. The spacious and historic park will be vastly renewed with over $2 million in upgrades, including redesigned athletic fields for the sports enthusiast. There will also be additions that will include open-air pavilions and more. The current project is expected to be completed within the next four years. An underground basin will collect and temporarily store rain and sewage from three overflow locations that now dump on average 115 million gallons into the Ohio River. The sewer overflows that are produced from heavy rain are expected to drastically decrease by at least 75% upon completion of the project. The tunnel will serve nine combined storm and sewage overflow points. Additionally, some trees will be removed and replaced with appropriate landscaping.  This western Louisville Park has been in line for a major overhaul for some time and is now being renovated entirely. The underground basin will be 480 feet by 208 feet, and 55 feet deep-deep enough to enclose a five-story building. Interesting fact: Louisville has had 11 storms with 3 inches or more of rain in 24 hours in the last decade. Contact us today for all your pipelining needs:...

Go for the Green: University of Louisville’s Sustainability

University of Louisville is working with Louisville’s Metropolitan Sewer District (MSD) on a variety of green infrastructure projects to help keep storm water runoff out of the combined sewer system. In the past, every raindrop that hit U of L’s rooftops (over 2.2 million square feet on Belknap campus alone) and pavements was channeled into the same sewer system that handles sewage. The University has three campuses. The 287-acre Belknap Campus is three miles from downtown Louisville and houses seven of the university’s 12 colleges and schools.  The sewer system can potentially handle storm water from U of L, but the treatment plants at the end of the pipe often cannot.  This leads to unsavory conditions, as well as, dangerous releases of untreated sewage into the Ohio River, which poses a threat to human health and ecological integrity. The University has pursued means of lessening the risk of flood and reducing the campus’ contribution to the problem by diverting storm water from the sewer system all together, through infiltration and rainwater harvesting projects, or by slowing its release through water absorbing changes to the campus landscape. Around campus, there are disconnected downspouts, installed vegetated green roofs, and built rain gardens and bioswales to facilitate groundwater recharge through infiltration. In recent years, U of L made several changes to campus landscaping, parking lots and rooftops, with the help of $1.25 million in cost-sharing from the Metropolitan Sewer District. This year, MSD confirmed that U of L’s projects are diverting about 72 million gallons of storm water every year. This significant investment will essentially pay for itself by helping prevent millions of dollars in future flood damage. MSD’s investment in Belknap campus storm water projects is part of an $850 million agreement that MSD made in federal court with the U.S. Environmental Protection Agency and state regulators to reduce the incidence of combined sewer overflows into waterways during storm...

Lexington’s Operation Upstream for Storm Drains

Lexington’s Operation Upstream for Storm Drains

The City of Lexington is heading up a proactive community project: stenciling storm drains to prevent storm water pollution.  The community is coming together for the benefit of keeping pollutants that enter the waterways to a minimum. Many people do not know that storm drains lead directly to our waterways. Everything that enters a storm drain or storm inlet is washed into nearby streams, lakes, and rivers without going through a treatment plant. Only rainwater should go down the drain. Non-point source pollution, also called storm water runoff or urban runoff pollution, is caused when rainfall carries pollutants from roads, yards, buildings, and other surfaces into waterways. Because the pollution comes from many different places, it cannot be traced to a “point source” such as a factory or plant.  Pesticides, fertilizers, motor oil, paint, antifreeze, solvents, pet wastes, grass clippings, and yard waste can all harm our water sources if they end up in storm drains due to dumping or runoff.  Storm drains lead into a separate system, apart from the system that carries wastewater, and empties directly into our streams, rivers, and lakes. When motor oil is poured into the storm drain or pet waste is washed into an inlet, all of the bacteria and chemicals end up in the closest waterway. Storm drain stenciling helps educate citizens about water quality and tells people not to pour any chemicals or wastes down storm inlets or drains.  There are over 20,000 storm drains and inlets in Lexington so there are plenty to choose from.  Due to safety concerns, the City advises that you stencil in teams of 2-4 people. This allows at least one person to stencil while one person watches for traffic. The Division of Environmental Services has stenciling kits for you to sign out.
