Document Description
LADWP proposes to construction an iron and manganese treatment facility adjacent to the existing 99th St Wells Pumping Station in the Watts community of the city of LA. The proposed project would remove naturally occurring iron and manganese from the groundwater wells. Due to power line clearance requirements, the proposed project would require the relocation of existing 34.5 kV overhead power lines to be buried underground. The underground installation of the buried 34.5 kV power lines would begin northeast of the existing 99th St Wells Pumping Station Complex at the LADWP transmission station on Clovis along 98th St, and then north along Wadsworth Ave for a total length of approx 1,180 ft. Construction of the proposed project would include two phases. The first phase would include the undergrounding of the power lines and is estimated to occur during summer when the elementary school is out of session. The second phase would include the Fe/Mn treatment system installation and is anticipated to take 15 months.
