MVSD Water Distribution Main Valve Replacements, Phase I

Share

Meander Water, Mahoning and Trumbull Counties, Ohio

The Mahoning Valley Sanitary District (MVSD), now known as Meander Water, began providing water to the Cities of Youngstown and Niles in 1932.  Water is delivered through multiple force mains that originate from the Meander Water Treatment Plant.  CT Consultants was hired by the District to provide the engineering and construction services for the systematic replacement of valves and blowoffs in the distribution system due to the age and poor condition of the valves.  The first phase involved the replacement of key distribution valves at the interconnections with the City of Niles’ and City of Youngstown’s Water Distribution Systems and at the cross connections between the District’s transmission mains allowing for redundant water service.

The project replaced sixteen valves located throughout the transmission network.  Three force mains travel north from the treatment plant into Niles and three other force mains travel southeast from the treatment plant into Youngstown.  The three Niles force mains consist of two 20″ cast iron mains constructed in the 1930s and one 24″ ductile iron pipe main.  The Niles force mains included the replacement of Three 20″ and two 6″ valves.

The three Youngstown force mains consist of two 36″ riveted steel pipe mains constructed in the 1930s and one 48″ pre-cast concrete cylinder pipe constructed in the 1970s. The Youngstown force mains included the replacement of two 48″, four 36″, four 24″ and one 8″ valves on the Youngstown force mains.
