An Integer Program for Optimizing Sanitary Sewer Rehabilitation Over a Planning Horizon
Inflow and infiltration (I/I) associated with sanitary sewer pipeline and manhole defects have been known to cause unnecessary treatment expenditures. It is estimated that 10% or more of treated wastewater sources can be attributed to extraneous I/I. This paper documents an optimization model that analyzed costs and benefits of reducing the amount of I/I through selected rehabilitation methods recommended following a closed‐circuit TV inspection over a 20‐year planning horizon. An integer program was formulated using the General Algebraic Modeling System to optimize the sewer rehabilitation schedule and present value costs of repairs and I/I treatment. Results of a detailed analysis and the optimal rehabilitation schedule for a subshed of the Little Huntington Creek sewer system in Fairfax County, Virginia, are presented.
