Remote sensing diagnostic techniques
Cost and time saving preliminary inspections
Main premise is that most of sewer problems occur at or near maintenance holes
Calculate the average wastewater flow, Qavg = (70-80) % of average water consumption.
Select a peak factor, PF = [(18+√P)/(4+√P)], where P = population in thousands.
Calculate the peak wastewater flow, Qpeak = (PF * Qavg)
