Manhole Rehabilitation Pays Dividends for Decades


Wed, Mar 18, 2020 2:00 PM EDT

Beyond I&I reduction, the cause for Manhole Rehabilitation is clear: restore structural integrity, provide corrosion protection, and reduce flow to the WWTP for increased capacity and decreased cost. Understand the engineer’s role in assessment, specification, and onsite inspection. Know the contractor’s role—execution is everything. Hear testimony of municipal stakeholders on ROI and long-term performance. If you’re part of a team that cares about the collection system, Dividends for Decades is 60 minutes well invested. Learn well from a team of experts at Commonwealth Engineers, Culy Contracting, and Madewell Products.

What is Measured, Improves: Maximizing Infiltration Reduction and Rehabilitation Effectiveness


Locating and reducing inflow/infiltration (I/I) is a common challenge facing wastewater collection systems, yet effective identification of infiltration has been nearly impossible using Closed-Circuit Television (CCTV), Smoke Testing, and Dye Flood Testing results.

Too often Agencies only learn that I/I flow reduction goals were missed after multi-year flow monitoring results; citing ineffective prioritization, poor contractor performance, and inability to reliability certify repairs as watertight, especially after service restoration.

Today, Agencies are adopting machine-intelligent Focused Electrode Leak Location (FELL), in accordance with ASTM F2550, to identify I/I and test rehabilitation as watertight. Unbiased and automated inspection results are replacing legacy ambiguous and subjective testing to (1) prioritize pipes with the highest infiltration, (2) test the watertightness of repairs & that rehabilitation meets contract requirements, and (3) compare before and after leakage results to get ‘same day’ estimated percent reductions in flow.

The CIPP Wetout Standard: Plant, Process and Permit Requirements for a Licensed Facility

This presentation will educate job owners, engineers and installers on the importance of operating a licensed wetout facility by focusing on the critical, yet often overlooked, resin-impregnation step in the CIPP manufacturing process. With decades of manufacturing and installation experience, the presenters will detail the safety, quality and environmental requirements of a licensed facility designed to protect the communities in which these facilities operate and ensure CIPP project decision makers avoid some of the most common problems resulting from a lack of commitment to safety, quality and environmental stewardship.

Using FELL to Pinpoint Infiltration, Improve Decision Making, and Measure Rehab Effectiveness


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.

Best Value Engineered Design for a Sealed CIPP Collection System

LMKThere are several requirements for a successful rehabilitation project. First it is necessary to seal the entire collection system. Case study after case study has shown that repair/replacement of only main lines results in less than 50% of the infiltration removal. Manholes, and most importantly sewer laterals that connect businesses and homes to the main pipes, also need to be rehabilitated. Second, the collection system needs to be sealed and as watertight as possible. Third, the project must be sustainable, capable of performing over the long term, for the next 50-100 years.
