Title

Big Pine Wastewater Treatment Facility Expansion

Description

The Project consists of expanding the existing Big Pine Wastewater Treatment Facility from 10.3 acres to 15 acres, an increase of approximately 5 acres. The expansion will increase the capability of the wastewater facility by adding an additional new rapid infiltration basin in the expanded 5 acre lease area. The existing wastewater disposal facility has proven insufficient in years when the ground water is elevated in the area. This has occurred in 2017, 2019 and 2023 which were record snow and runoff years. Site soils will be used to create berms to enclose and create the new basin at a high higher elevation than the current existing infiltration/percolation basins located on the existing treatment facility area. This higher elevation of the new rapid infiltration basin will provide the needed separation from the ground water to provide the proper treatment and hydraulic head to allow for infiltration of the treated effluent into the ground water. The additional basin will also allow for continued compliance with the waste discharge requirements of the permit with the State Water Board. In addition to the new rapid infiltration basin there are projected future plans for the installation of a ground mount solar array which will provide needed power to the plant and allow it to have a net zero energy usage allowing ability to keep the rates in the community stable. The solar array will be installed through the future application of a building a building permit.
