Served as the lead project engineer on the design of rehabilitation of 25,000 linear feet of sewer pipe for the Santa Cruz County Sanitation District to correct excessive leakage (infiltration and inflow). The project rehabilitated the building laterals from the sewers up to the edge of the public right-of- way. More than 500 laterals with a total length of approximately 10,000 feet are included in the project. The rehabilitation options include replace and repair, pipe-bursting, and lining by various technologies. The construction cost of the project was $3.3 million. The project was done on an expedited basis to prevent a recurrence of overflows from a pump station. The complete design took just seven weeks.
