Using FELL to Pinpoint Infiltration, Improve Decision Making, and Measure Rehab Effectiveness
Wednesday, April 3, 2019 at 1:00 PM Eastern Time
By removing operator “interpretation” and engineer “judgment,” FELL can decide “if” and “how much” a pipe leaks.
Oftentimes, users find that 25% of their pipes in a given sub-basin are responsible for 75% of the infiltration, allowing users to cost-effectively target rehabilitation.
As a result, Sanitary Sewer Evaluation Studies (SSES) can now pinpoint locations of infiltration, and more importantly, differentiate sources of infiltration (i.e. main, lateral, lateral connection, manhole) and estimate Gallons Per Minute (GPM), for each.
By knowing infiltration rates before and after CIPP lining, users can also measure the effectiveness of their rehabilitation program, immediately following curing or installation, reporting same-day reductions in GPM, without delay.
Participants Will Learn How:
1. To reliably locate & measure sources of infiltration – quantifying results by sewer main, lateral, lateral connection, and manhole.
2. To use FELL to assist in rehabilitation decision-making, i.e. determining cost effectiveness of rehab selections of sectional v. full-length liners.
3. Pre- and post-CIPP FELL inspection quantifies & tracks infiltration reduction to measure rehabilitation effectiveness.
4. FELL is used to avoid unnecessary repairs, i.e. to avoid costs.
