This project is to help inform the larger Wawona Wastewater Treatment Plant upgrade in 2019 which will include two lift station improvements, various wastewater treatment process components, overall treatment capacity, and improvements on the effluent disposal.
The geotechnical investigations will include twenty 6-inch holes (5 feet deep) for percolation tests, and twenty 2-inch holes (12 feet deep) to install piezometers to track groundwater conditions. Holes will be dug either manually with hand augers or using a gas-powered hand auger. The percolation holes will be backfilled immediately after completion of percolation testing.
