Description: The Scope of I/I in Tennessee – Quantifying the Problem Using Public Records
The Scope of I/I in Tennessee – Quantifying the Problem Using Public Records
Abstract
This independent, non-funded study evaluated NPDES reports submitted by the 235 municipal treatment plants in Tennessee to develop a statewide estimate and rank of I/I levels. The evaluation process used influent BOD, and peak and average influent flow values. The initial study identified 279,996,115 m3 (73,975 mill. gal) of I/I annually (representing about 30% of the total flow in collection systems. A follow-up study was begun using the monthly operating reports which included daily influent values. Thirty-four systems have been evaluated (13%) and 22 had more than 50% I/I. This study also correlates I/I estimated by flow fluctuation with indications of dilute influent BOD. The analytical procedure is brief and simple and is recommended to regulatory agencies for developing I/I management and rehabilitation funding strategies.
