Recycled Water Pipeline Extends to Skyline Park
NSD is currently constructing a section of recycled water pipeline from Napa State Hospital (NSH) to Skyline Park. This segment is the first step in potentially bringing recycled water to the MST area. This construction was made possible by construction cost savings on the recycled water pipeline from Napa Valley College to NSH, and is supported by American Recovery & Reinvestment Act funds..
