Muldrow, OK Meets Compliance Needs by Meshing Old with New

February’s feature article in Municipal Sewer and Water features the Town of Muldrow in Oklahoma, who is understanding the risks lurking in their collection system and meeting compliance needs, while performing all preventative maintenance in-house with a lean crew.

“Incorporating the SL-RAT for assessing our whole collections system, which is fairly spread out, was an enlightening moment for everybody within our staff. It enabled us to get out in the field, pop manholes, investigate them quickly and see all of the problems that we had throughout the collections system.”

SL-RAT saving Utah cities like Ivins water & money

The City of Ivins, UT, was maintaining their sewer lines like most utilities around the country – by cleaning the entire system on a time-based schedule. In Ivins case, they were cleaning 50 miles annually to prevent a handful of backup incidences. Since 2020, Ivins, Santa Clara and the Ash Creek Special Service District conducted a pilot acoustic inspection program with the help of R.H. Borden and Co.

Instead of cleaning every pipe, they discovered, by using the SL-RAT, that only 5% of the system actually required maintenance. Thousands of gallons of water, wear and tear on expensive cleaning equipment, and thousands of manhours were saved by inspecting prior to cleaning.

“This is the future. Eventually everyone will do it this way. I just feel like we saw a technology that might work, and it did.”

– Chuck Gillette, Ivins Public Works director
