The City of Salisbury needed a city-wide I/I study and sewer system evaluation strategy. The City hired RJN to develop this strategy and conduct initial field investigations, including flow monitoring and manhole inspections for the first of the three-phase study strategy developed. RJN also prepared a final I/I analysis and MH I/I source report based on the field data collected. Additional phases of the strategy include additional source identification field inspections in Phase 1 and starting the phased process in Phases 2 and 3.
