MSD budgets $200 million for Ohio River Tunnel project – WDRB 41 Louisville News

The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville. LOUISVILLE, Ky. (WDRB) – The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville. According to Jacob Mathis, an MSD engineer and manager of this project, just a tenth-of-an-inch of rain can overwhelm parts of the sewer system in the district, sending stormwater and drainage straight into the Ohio River or Beargrass Creek. “In a typical year, there’d be four billion gallons of sewage released into these waterways,” Mathis said. In hopes to reduce sewer drainage across the country, the federal government is requiring communities to find ways to mitigate the damage by Dec. 31, 2020. If Louisville does not meet the deadline, the government could enforce fines or penalties. In response, MSD engineers devised a plan of three new basins in three different neighborhoods to store overflow. But there were concerns over how much that could interrupt construction, business and daily life. MSD decided to take a different route and came up with the Ohio River Tunnel project. “This project is one of the first of its kind in Louisville or even the state of Kentucky,” Mathis said. Engineers describe it as being on the same level and magnitude as the Ohio River bridges undertaking. But this project is intended to be out of sight, out of mind. “There will be less disruption to the community itself with traffic impacts, economic impacts,” Mathis said. “We won’t disturb the big economic corridor along Main Street.” The tunnel will start underneath what will be the western part of Waterfront Park near 13th and Rowan Streets. It’ll head east underneath the Ohio River towards I-64. At the Second Street Bridge, the tunnel then jogs inland to Butchertown. [...]

Drilling in Southwest Indiana at a 15-year peak

Indiana State officials say Southwest Indiana is experiencing a boom in oil and gas exploration, with a peak number of wells drilled over the past 15 years. The Indiana Department of Natural Resources Division of Oil and Gas released a report earlier this week that says oil and gas wells are being drilled in Indiana "At a pace that hasn't been seen for at least 15 years," according to Herschel McDivitt, director of the DNR Division of Oil and Gas. DNR officials say the division issued more than 450 drilling permits in 2006, a number that McDivitt expects to steadily increase during the next several years, due to the anticipated higher prices for crude oil and natural gas. "This is an exciting time to be in the oil and gas business," McDivitt said in a press release announcing the news. "While much of the interest is in drilling for crude oil, a growing number of wells are being drilled for natural gas, especially in the southwestern part of Indiana where companies are actively developing wells." McDivitt acknowledged that along with the increase in drilling applications has come a significant number of questions from landowners who have been approached by companies seeking to obtain leases from the landowners allowing them to drill on their properties. "Many landowners are unfamiliar with the process of leasing their land for oil and gas and are seeking more information about oil and gas operations and looking to find answers to their questions," McDivitt said. DNR has also made some changes in the Division of Oil and Gas's organizational structure. Jim AmRhein will be responsible for all inspections and compliance- related functions within the division's program. Previously, AmRhein was in charge of all permitting functions, as well as inspections and enforcement duties in central and northern [...]

Upcoming Tunneling Projects – Tunnel

2/10/2016 Upcoming Tunneling Projects CALIFORNIA Laguna Beach Tunnel   Stabilization   and   Sewer   Pipeline   Replacement Approved by the South Coast Water District Board of Directors in 2010 and the City of Laguna Beach in late 2013, the Tunnel Stabilization & Sewer Pipeline Replacement Project (Tunnel Project) is a 100-year solution to protect the environment, local economies and neighboring communities. The project comprises two key components: Tunnel Stabilization: The District will enlarge the size of the tunnel from an average of 6 to 9 ft. This will ensure safer working conditions and greater access for future pipeline maintenance and repair. Permanent shotcrete lining and steel supports will be installed at several locations where required, replacing rotten timber supports and removal of loose rock that currently exist. Pipeline Replacement: The District will install a new 24-in. pipeline throughout the tunnel. The current pipeline – also 24 in. in diameter – will be encased in concrete, but preserved for redundancy and emergency use. The cost to repair the tunnel is estimated at approximately $90 million and will be funded through low-interest state loans, grants and the District’s general fund. Shortlisted tunnel contractors announcement was anticipated for 2014-2015 with request for bids expected in 2015 and NTP in 2015-2016. Los Angeles The   North East   Interceptor   Sewer   (NEIS)   Phase   2A The North East Interceptor Sewer (NEIS) Phase 2A project is currently the northern extension of the NEIS Phase 1 project. The project will construct approximately 3.03 miles of 8-ft diameter sewer in tunnel and associated structures. The sewer will be constructed from the Division St. Shaft site, near the intersection of San Fernando Road and Cazador Street and terminate at the northern overflow parking lot for the Pony and Train Rides in Griffith Park, just north of the I-5 Griffith Park On/Off Ramps (I-5 Shaft Site) east [...]

I-65 construction south of Indy tests commuters’ patience

Trips from Southport to southern Johnson County can take up to an hour longer Story Highlights More than $286M in road projects from Indy to Louisville on I-65 this summer. 20 motorists have died in accidents on I-65 this year Southside commuters are swerving, merging and yielding a lot for road construction this summer — and there’s little relief in sight. From Southport Road to Edinburgh and beyond, concrete testing barricades and orange traffic barrels on Interstate 65 have led drivers through myriad lane shifts and closures, adding precious time to rush-hour commutes, as the highway and bridges are rebuilt or repaired. Alternative routes, including portions of U.S. 31, also are being revamped. “There aren’t too many areas (of I-65) where we don’t have construction testing and inspection going on right now,” said Indiana Department of Transportation spokesman Harry Maginity. “If you are driving from Indianapolis to Louisville (Ky.), you are going to see a lot of it all year.” INDIANAPOLIS STAR I-65 NB lanes reopen in Lafayette area The biggest projects are on I-65 around Greenwood where about 63,000 cars travel both ways each day. Heavy machinery in the blocked-off medians and on bridges has made space in the travel lanes tight and twisting. Combined with reduced speeds, the journey in and out of Indianapolis can add more than hour of travel time for a trip between Southport and Edinburgh. “Our drivers plan that a trip from I-465 on the Southside to Edinburgh is going to be 45 minutes slower,” said Tim Piper, owner of Same Day Transportation, Indianapolis, which has 35 trucks. “If there’s an accident, it’s going to be even longer.” Overall, INDOT Construction Testing is doing three repair projects worth a combined $156 million on I-65 in the metro area. Four other projects to the Kentucky [...]

Louisville Indiana – Kentucky Ohio River Bridges Project

https://www.youtube.com/watch?v=26r9MpVATsI Today's "Walk the Bridge" event attracted tens of thousands of people. The Louisville-Southern Indiana Ohio River Bridges Project addresses cross-river transportation needs in Louisville, Kentucky and Southern Indiana and will result in safer travel, less congestion and improved access to destinations in the region. LOUISVILLE, Ky. – Governor Steve Beshear announced that the new Ohio River bridge between Kentucky and Indiana in downtown Louisville will be named the Abraham Lincoln Bridge – connecting, as it does, the states of Lincoln’s birth and raising. “Lincoln led our nation through its bloodiest and greatest constitutional and political crisis – the American Civil War,” Gov. Beshear said. “But at the end of that national trauma, we remained a ‘United’ States of America. It’s therefore fitting that we honor Lincoln’s legacy with a bridge that further unites Kentucky, where he was born, with Indiana then Illinois, where he emigrated as a youth and grew to adulthood.” Kentucky and Indiana jointly are building the bridges project to improve cross-river mobility between Louisville and Southern Indiana. The project also includes construction of a new bridge eight miles upriver, connecting Prospect, Kentucky, and Utica, Indiana.  

St. Louis Area Flood Plains and Levees

As water rushed toward St. Louis in May 2015, attention is on geotechnical runaway development that has occurred since the floods of 1993. ST. LOUIS, — Miles and miles of bigger and stronger levees have been built along the Missouri and Mississippi Rivers since the deadly floods of 1993, and millions of dollars have been spent on drainage improvements. Building is happening on flood plains across Missouri, but most of the development is in the St. Louis area, and it is estimated to be worth more than $2.2 billion. Though scientists warn about the danger of such building, the Missouri government has subsidized some of it through tax financing for builders. The existing alignment of the Missouri River levee and embankment system is recognized to have breach/foundation distress from  underseepage and boil activity concerns as a result of hydrologic conditions and flow constrictions.  The repetitive cycle of repairing levees in place after each major flood event has resulted in increased O&M and RR&R costs, increased flood risk, and a general concern over the effective level of protection.  Levee repairs in place do not reduce flood  risk. Additionally, the current alignment of federal levees has acted to disconnect the river from its historic floodplain causing environmental degradation  and impaired habitat for fish and wildlife.    It several locations, bridges (rail and highway) and abutments, have encroached into the river’s conveyance area, increasing stages on the upstream side and increasing velocities on the downstream side, which also influence the performance of the levees.

Percolation test

Testing method A percolation test consists of digging one or more holes in the soil of the proposed leach field to a specified depth, presoaking the holes by maintaining a high water level in the holes, then running the test by filling the holes to a specific level and timing the drop of the water level as the water percolates into the surrounding soil. There are various empirical formulae for determining the required size of a leach field based on the size of facility, the percolation test results, and other parameters. For leach line testing, a minimum of three test holes are drilled, most commonly six to eight inches in diameter. Ideally, these should be drilled to different depths from three to six feet below the surface. For better, more conclusive results, five drill holes are used in a pattern of one hole at each corner of the proposed leach field and one test hole in the center. Testing of these holes will result in a value with units of minutes per inch. This value is then correlated to a predetermined county health code to establish the exact size of the leach field. Testing for horizontal pits typically requires five to eight test holes drilled in a straight line, or along a common contour, from three to ten feet below the surface. Testing is identical to leach line testing, though the end result is a different type of septic system, established through a different calculation. Vertical seepage pits are slightly different in testing methods due to their large size, but the basic testing method is essentially the same. A hole, typically three to four feet in diameter is drilled to a depth of twenty or thirty feet (depending on the local groundwater table), and a fire hose is used to [...]
