Savin was responsible for conducting field investigations for the preliminary design phase of the program. We installed and maintained flow monitors in several of the larger interceptors and combined sewers in Manhattan, Brooklyn, and Queens in order to evaluate the in-line storage capacity and the effect on the upstream collection system. Approximately 35 meters were installed and maintained during the initial monitoring period.

In addition, Savin conducted walk-through television inspection of approximately 50,000 linear feet of interceptor and combined sewer. The structural condition and capacity for in-line storage was evaluated.
A two-man raft was used to inspect over 25,000 feet of interceptor that could not be walked. Savin was responsible for obtaining permits and all maintenance and protection of traffic.

Additional work included confirmational flow metering and regulator inspection. Savin videotaped sub-grade junction chambers and confirmed dimensions shown on drawings.
