CityWorks Integration with SL-RAT in Augusta, GA

The Spring Edition of CityWorks’ InPrint publication highlights Augusta GA’s ability to streamline work processes through pairing two technologies. By integrating SL-RAT acoustic data with CityWorks software, they have established an automated system that allows for easy understanding and transparency of workflow. Creating such a process has allowed for improved response time to potential causes of SSOs.

“The response time was the biggest benefit for us. We had SL-RAT crews out in the field, and when they found blockages, they routed their inspection work order directly to their cleaning crews.”

– Jerry Philpot, IT & Technical Support Manager for Augusta, GA

Article: Santa Barbara Incorporates Acoustics to Prioritize Sewer Maintenance

Santa Barbara’s collection system relies on a cleaning cycle ranging from one month to 60 months. While they have been successful at reducing SSOs through increased cleaning efforts, they looked to further enhance efforts. Santa Barbara discovered that the majority of SSO events occurred from 6-in pipes on a 60-month cleaning cycle. Based on cost, speed and simplicity, they chose the SL-RAT to acoustically screen these lines to get a quick understanding of pipe conditions and deploy resources appropriately.

“We wanted to clean or inspect more. Prior CCTV work has helped us find structural defects and generate a rehabilitation backlog. The SL-RAT allows us to inspect much more pipe now and find blockage conditions before they create an SSO.”

– Chris Toth Santa Barbara Wastewater Manager.

Several pertinent excerpts are included below:

“The results of this demonstration of the SL‐RAT show promise for the application of this technology as a tool for cost‐effective, pre‐cleaning assessment and post‐cleaning quality assurance. The application of this technology in an overall collection system O&M program should enable wastewater utilities to optimize their sewer cleaning efforts and free up valuable resources to more effectively implement critical CMOM and asset management programs.”

 

“Rapid assessment approaches and tools provide an avenue to significant pre‐cleaning inspection cost savings that could be achieved through reduced inspection and non‐productive cleaning costs.”

 

“The emergence of acoustic sewer inspection technologies, like SL‐RAT, as rapid deployment, low‐cost, reliable, pre‐cleaning assessment tools is focusing growing attention on the potential for more cost‐effective sewer cleaning programs. Through the ease of deployment, reduction of cost, increases in reliability of these inspection approaches, combined with the potential for reducing the “cleaning of clean pipes,” significant cost savings are attainable. As utilities apply these new inspection technologies, they can move towards implementing sewer cleaning programs that consist of planned directed and quick response, reactive cleaning. Also, these cost savings can be realized while improving collection system performance and the protection of public health and water quality.”

 

“The results of this demonstration project reveal the potential for more cost‐effective sewer cleaning programs. The site specific pre‐cleaning assessment inspection costs resulting from this project and MSDGC’s historic practices for CCTV (on‐road), CCTV (off‐road), and SL‐RAT (on‐and off‐road) are $1.68/ft., $2.03/ft., and $0.14/ft., respectively. So, for pre‐cleaning assessment, the application of the SL‐RAT can reduce MSDGC’s costs by $1.54/ft. for on‐road sewers and $1.89/ft. for off‐road sewers. In addition, by moving to a sewer cleaning program predominated by planned directed cleaning, MSDGC can save $2.00/ft. by reducing its “cleaning of clean pipe.” In total, when costs of conventional CCTV inspection and cleaning are combined, for each pipe segment that is deemed “clean” using the SL‐RAT, MSDGC can save $3.54/ft. for on‐road sewers and $3.89/ft. for off‐road sewers.”

Article: Augusta Utility Incorporating SL-RAT to Address Assessment Program (MSW Cover Story)

Augusta, Georgia has been under a consent order from the Georgia Department of Environmental Protection to do a system wide evaluation. With the mission of mapping and evaluating their entire system, the SL-RAT has been a pivotal instrument for quickly screening small-diameter pipes for blockages. Their one SL-RAT crew is averaging 7,000 ft of pipes assessed per day, which in combination with root and grease control programs has reduced overflows by 25%.

“We’re taking baby steps, but the SL-RAT is one of those things that’s turning the baby steps more into a full stride. I honestly can’t say enough good things about it.”

– Jody Crabtree Asset Manager for Augusta Utilities Department

Article: Charlotte Deploys New Acoustic Inspection Technology to Reduce Cleaning Costs and SSOs

The City of Charlotte, NC maintains more than 229,000 connections through 4,100 miles of sewer collection pipe. To address the challenge of maintaining this complex collection infrastructure, the Charlotte-Mecklenburg Utilities Division (CMUD) partnered with the University of North Carolina at Charlotte in 2005 to develop technologies for pipe inspection. The developed acoustic inspection technology, called SL-RAT, has inspected over 1 million feet of sewer pipe, demonstrating that the SL-RAT can quickly provide operators with valuable information on pipe conditions.

“We’re saving money and saving our time with the us of acoustics. You can see immediately what needs to be cleaned, so it takes the guesswork out and focuses your efforts.”

– Jon Beam, Environmental Program Inspector for CMUD
