Lilly Imani is an assistant engineer with Sacramento County Water Agency (SCWA) currently supporting various water supply and infrastructure projects in the Operations and Maintenance Engineering division. Prior to joining SCWA, Lilly worked in the private sector as a staff engineer for Caliskaner Water Technologies (CWT) and Kennedy Jenks (KJ).
At CWT and KJ, Lilly’s work focused on full-, demonstration- and pilot-scale installations of advanced primary and secondary treatment technologies for wastewater treatment. Under the guidance of her mentor, Onder Caliskaner, and close collaboration with the municipal wastewater treatment plants and technology manufacturers, Lilly operated and maintained five different advanced technology pilot units. Lilly collected samples for third-party laboratory analysis (e.g., COD, TSS, ammonium, nitrate, and particle size), maintained continuous monitoring inline sensors and analyzers, prepared work orders, and developed standard operating procedures for the pilot units. Lilly performed data analysis to evaluate the performance of the advanced treatment technologies compared to conventional treatment. In her first project, Lilly worked on the evaluation of primary filtration (Aqua-Aerobic Systems full-scale cloth disc filter) and biofiltration (WesTech pilot-scale FlexFilter) to replace primary sedimentation in wastewater treatment. The project was sponsored by the California Energy Commission to quantify the energy savings potential of various advanced primary treatment technologies. At KJ, Lilly was the lead engineer for a tracer study that established a new disinfection baffling factor for a 5 MGD water treatment plant and provided engineering support for two urban water management plans, a wastewater effluent disposal study, a grit removal study, and an alternatives analysis report that compared four lining alternatives for water distribution piping.
Lilly received her B.S. in Chemical Engineering and M.S. in Civil and Environmental Engineering from the University of California, Davis. For her thesis project, Lilly designed and operated four bench-scale biological filters intermittently fed with synthetic greywater to evaluate the effect of filter media type (non-woven fabric, pumice, sand, and biochar) on removal performance. Lilly monitored common water quality parameters and bacteria (E. coli, enterococci, and staphylococcus aureus) in influent and effluent samples.
Brian G Davis P.E., is currently the General Manager of the Linda County Water District, providing municipal water and sewer service to approximately 30,000 residents of Yuba County.
