Registration & Breakfast Buffet – 8am

Program – 8:30am

The ALCOSAN Wastewater Treatment Expansion and the Ohio River Tunnel (ORT) Project are part of The Clean Water Plan (CWP), a $2 billion, long-term plan ALCOSAN submitted as a solution to eliminate approximately 7 billion gallons of combined sewer overflows (CSOs) annually into the Ohio, Allegheny, and Monongahela Rivers by 2036.  As required by a Consent Decree signed by the U.S. Department of Justice, U.S. Environmental Protection Agency, and the PA Department of Environmental Protection, ALCOSAN is required to implement the CWP with an aggressive schedule.

The CWP includes the proposed expansion at the Woods Run WWTP.  The proposed upgrades will expand the WWTP wet weather primary treatment capacity to 600 mgd. The secondary capacity of the WWTP will be increased to 295 mgd, from its currently permitted full treatment capacity of 250 mgd. The major projects associated with the expansion include a wet weather pump station, a 360 mgd east headworks facility, additional primary sedimentation and final secondary settling tanks, solids thickening and dewatering improvements, and construction of a second chlorine contact tank with a dry weather discharge outfall.

The Ohio River Tunnel (ORT) is the first of three new, large diameter deep tunnel projects that ALCOSAN will use toward the CWP’s overall goal to significantly reduce CSOs released into the region’s three rivers.   The ORT Project includes one main rock tunnel (approximately 150 feet below ground) generally running parallel to the Ohio and Allegheny Rivers and two branch tunnels crossing beneath the Ohio River.   The primary components of the ORT project include the main rock tunnel, ten shafts, two branch tunnels (Chartiers Creek and Saw Mill Run) and several near surface facilities.

 

Speakers: Mike Lichte and Kim Kennedy
