The Lancaster and Palmdale Water Reclamation Plants are currently being expanded and upgraded. In order to provide Antelope Valley residents with a centrally located and easily accessible information office regarding these activities, the Antelope Valley Field Office was opened on November 28, 2005. Additionally, the AVFO allows regulators, government officials, and other interested parties to conduct business with the Sanitation Districts on issues related to wastewater treatment in the Lancaster and Palmdale areas.
