Inflow and infiltration is a problem for all wastewater systems, accounting for a significant portion of overall flow in older systems. Reducing this inflow and infiltration can be very expensive — and so it can be essential to measure the cost-effectiveness of reduction efforts beforehand.
In this video interview Andy Lukas, wet weather practice leader for Brown and Caldwell, describes current cost-effectiveness measuring techniques and outlines a new approach to evaluating I/I reduction cost-effectiveness.
