Tips for birding Green Valley Wastewater Reclamation Facility
Under construction, access on weekends only for now. Protocol for visiting when open: use the call box at the gate, sign in at the office on the west side of the complex before birding, and stay away from buildings and construction equipment. If gate is open, proceed to office to sign in. Sign out when finished.
