Colorado Special Districts Pool Approves RH Borden Process

The Colorado Special Districts Property and Liability Pool announced the approval of an annual condition-based maintenance process provided by RH Borden “as an acceptable Best Practice alternative methodology for sewer maintenance as well as … fully compliant with the CSD Pool Sanitation Maintenance Warranty Program.” The SL-RAT helps collection system managers improve maintenance efficiency by identifying risk areas and reducing unnecessary cleaning. This approach helps to reduce water usage while integrating a process for maintaining a cloud-based GIS system of sewer assets.

The approval of this condition-based maintenance program allows CSD Pool members to receive a 5% group purchase discount on equipment and services from RH Borden, and “may effect a 33% discount on General Liability coverage.”

RH Borden has helped dozens of utilities in Utah and neighboring states with conducting acoustic inspections and manhole scanning. Learn more about RH Borden and Company here: https://www.rhbordenandcompany.com/

Improving Cleaning Efficiency at City of Eagan, Minnesota

Eagan SL-RAT User

The City of Eagan in Minnesota suspected that significant resources were deployed to clean pipes that did not need maintenance through their time-based maintenance program. In 2018, Eagan started using the SL-RAT to screen pipes prior to cleaning. By using a summer crew to inspect their yearly cleaning objectives, they could save more than $150,000 and 3,000 crew hours annually that would have been used to clean pipes with plenty of flow capacity.

The SL-RAT is compact, it’s extremely reliable, it’s robust and it does exactly what it’s supposed to do. We wanted to be more efficient and the technology is viable for what we’re trying to do.Brent Massmann, Utilities Operations Supervisor | City of Eagan

Bend, Oregon Incorporates Innovative Technologies to Meet Initiatives

The City of Bend (Oregon) Utility Department oversees 474 miles of pipe for it’s 94,000 residents. The city has experienced rapid population growth, from 34,000 in 1999 to 94,000 in 2019. Despite experiencing rapid population growth and development, the city has adopted new technologies to ensure that SSOs are down and preventative maintenance tasks are on target, without increasing staff headcount. One of the technologies Bend is utilizing is the Sewer Line Rapid Assessment Tool (SL-RAT). By using acoustic inspection technology to rapidly inspect lines, they are eliminating unnecessary cleaning, redundant vehicles and high energy labor practices.

Typically, our system is in good shape in newer areas where it is predominantly PVC and doesn’t need cleaning. This assessment tool helps us focus our line-cleaning and root0cutting efforts where we need it, such as the older parts of town. It is helping us get through our system better, faster and eliminating SSOs.”

 

– Orrin Libolt, Collection System Supervisor, City of Bend Utility Department
