The City of Los Angeles provides wastewater collection and treatment for residents, businesses and industries located within the City and twenty-seven contract agencies. The Terminal Island System serves the southern portion of the City. This subsystem has one treatment plant, the Terminal Island Treatment Plant, located in the Los Angeles Harbor area.
This project was developed to improve unit process control and materially enhance the ability of the plant operators to control the treatment process and therefore comply with effluent discharge requirements.
This project also involved the design and installation of sluice gates in the walls separating each tank, replacement of the diffusers/piping in the mixed liquid channel, replacement of the diffusers/piping in influent channel, replacement of foam spray nozzles, insulation of air headers, and installation of flowmeters.
Dean Ryan participated in the comprehensive evaluation, preliminary design, plan production, training and start-up of various Aeration Tanks. This activity included the relocation of underground utilities, the design, upgrade and installation of new and existing equipment. Total Project Cost: $1,785,000.
