Optimizing Root Control with Acoustic Inspections- Western Virginia Water Authority

Western Virginia Water Authority is a mid-sized utility in Southwest Virginia that provides water and sewer service to ~250,000 people. In 2016, they started looking for ways to optimize the process for identifying pipes for chemical root control. To effectively manage an abundance of CCTV work orders, Western Virginia Water Authority utilized acoustic technology to screen their system for potential blockages. Over 4,500 acoustic inspections were conducted, resulting in identifying 557 with Blocked or POOR/low FAIR blockage assessments – scores of 0 to 4. Resources could be allocated to the 12% of pipes with identified need.

“The use of the SL-RAT greatly reduced the amount of time that needed to be spent televising and allowed for quick screening of the system.”

SL-RAT Improving Sheridan’s Sewer Program

Sheridan’s City Utilities Director, Dan Roberts, describes how the Sewer Line Rapid Assessment Tool, or SL-RAT, has helped the city develop more targeted maintenance plans. Roberts says, “The device is really changing the game for us about how quickly we can assess sewers and then determine what is needed to actually maintain them.”

Sheridan’s previous approach consisted of a time-based maintenance program, inspecting the city’s 130 miles of pipeline at three year increments. Like most utilities, this leads to using time and resources to clean already clean pipes, and missing critical areas with blockages. By using the SL-RAT to quickly screen before deploying resources, Sheridan can have a more targeted cleaning approach.

OMAG’s Users Give Feedback on SL-RAT

Since fall of 2018, OMAG (Oklahoma Municipal Assurance Group) has provided three SL-RATs for member utilities to update and develop their sanitary sewer maintenance programs. Jay Neal from the City of Durant and Matt Duke from City of Muldrow give feedback on their SL-RAT integration process.

When asked, “Did the SL-RAT meet your expectations as to its usefuleness?”:

It exceeded our expectations. As with all newer technologies, it’s easy to be reluctant to accept its usefulness. However, the SL-RAT proved up to the challenge. Once we figured out its limitations and the best time of day to put it to use, it gave us an accurate picture of our sewer infrastructure and provided the data necessary to analyze it.

Let it Flow. Mayor Davis, Suez-Bayonne Credit New Technology for Decrease in Blocked Sewer Lines

The City of Bayonne, since integrating the SL-RAT, has experienced an 83% decrease in blocked sewer lines in comparison with the same 6-month time period in 2018. By utilizing acoustic technology to scan for blockages, the city has effectively developed a preventative pipe cleaning operation.

Many cities deal with blockages in aging sewer systems. Bayonne is one of them. We hope this new technology will lead to a continuing improvement in the sewer system in the years ahead.

City of Augusta uses GIS and CityWorks to manage SL-RAT data (video)

When the City of Augusta started utilizing the SL-RAT to screen their collection system, they discovered that the SL-RAT generated a lot of valuable data at a rapid pace. They wanted to find a way to manage this process and have this information drive decision-making in the field. Augusta utilized their GIS system and CityWorks to automate this process.

We have quality, valuable information tied to our GIS system, so that you can evaluate things much more easier geographically.

Acoustic Inspection in Australia & New Zealand – Rapid Solution to Overflow Issues

The Sewer Line Rapid Assessment Tool, or SL-RAT, is allowing utilities in Australia and New Zealand to save time and money, while enhancing their sewer maintenance operations. By using acoustic inspection technology to quickly screen sewer pipes for blockages prior to deploying resources, segments with identified need can be prioritized. Since acoustic inspection costs significantly less to operate than traditional visual inspection, it can be a cost-effective way to establish a condition-based maintenance program.

When Sydney Water launched an acoustic inspection pilot program, they discovered that “60% of pipes in the Sydney Water cyclic cleaning program did not require further cleaning.” This means that with the integration of acoustic technology, Sydney Water can prioritize resources, time and water on areas with identified need, resulting in better service and increased environmental protection.

Taupo, New Zealand integrated the SL-RAT after experiencing an increase in number of sewer overflow incidents. “By using [the SL-RAT], there is a significant cost and time saving over traditional methods and the asset data gained by using SL-RAT is a valuable tool for reducing sewer overflows.” says Taupo District Council 3 Waters Network Engineer, Graeme Jackson. “The SL-RAT has proven to be a robust, quick and easy to use product. We have been able to address the immediate issues with our sewer network and significantly reduced the number of sewer overflows, with the added bonus of collecting excellent asset data.”

Elizabethton, TN focuses cleaning efforts with acoustic technology

Elizabethton, TN Water Resources oversees a 70 mile sewer system serving 28,000 people. In order to address aging infrastructure and leaky sewer pipes, the utility had to create an asset management program utilizing mapping software. Their approach involved assessing entire neighborhoods and focusing efforts on areas with greatest need. In order to ensure resources were allocated in the most efficient way, they implemented acoustic technology to understand pipe conditions before deploying more expensive resources.

“The SL-RATs are helping by quickly identifying the locations of obstructions…it’s much more focused than trying to televise the entire 70-mile system. The SL-RATS tell us where we need to spend more time on CCTV investigation. The CCTV investigation tells us whether we need point repairs, sliplining or replacement.” says Johann Coetzee, Water Resources General Manager.
