LATROBE TREATMENT SYSTEM

The Upper Latrobe Passive Treatment System was designed and constructed in 2009/2010.  The system consists of 3 settling ponds followed by a large constructed wetland.  The average inflow is 450gpm containing 45mg/L Fe.  The system has removed 90% of the Fe to date.

The treatment system is on land donated to the Loyalhanna Watershed Association (LWA) by the Latrobe Foundation.   Funds to design and construct the system were provided by the Pennsylvania Department of Environmental Protection Growing Greener Program through a grant to LWA.  The system was designed by Iron Oxide Recovery, Inc. (IOR) who also managed the day-to-day project activities and prepared this Operation and Maintenance (O&M) Plan.  LWA is responsible for the long-term O&M of the treatment system.
