City uses data-as-a-service to improve efficiency

Problem: The city of Grand Rapids, Michigan, maintains a collections system that includes 1,100 miles of sanitary sewer pipe and 385 miles of stormwater pipe. The age of the collections system varies with some segments over 100 years old. Like the vast majority of collections systems, Grand Rapids is challenged with wet weather events that result in I&I. In 2022, the city pivoted its approach and sought out a partner to take responsibility for the operation and maintenance of the monitoring network including hardware, software and data preparation. This enabled the city to focus solely on data analytics, thus embracing the data-as-a-service model.

Solution: Grand Rapids, through their services provider, ADS Environmental Services, now has 36 flowmeters and 10 rain gauges deployed in both their sanitary sewer and stormwater collections systems. In the stormwater system, the city looks at peak flows in wet weather and flows (possibly illicit) during dry weather. The systems are set up to acquire data at set intervals of every 5 minutes on an ongoing basis. Typically, data is transmitted once per day to cloud-based software where it is stored for viewing and analytics.

Result: The service provider’s in-depth monitoring experience provides assistance with determining monitoring locations and installation methods, assuring that the most relevant data is acquired. This has allowed city operations to refocus on projects and tasks utilizing their core capabilities. 800-633-7246; www.adsenv.com


Cherne case study

Contractor relies on pipe plugs for inspection and cleaning operations

Problem: Miller Underground offers comprehensive sewer infrastructure solutions, including catch basin cleaning, hydroexcavation and CCTV inspections throughout North America. “Each day presents a unique challenge that requires diverse testing equipment,” says Samantha Da Silva, combo truck operator and shop manager. “Strict adherence to a checklist for handling pipe plugs is crucial.”

Solution: During sewer inspections and maintenance, Miller Underground relies on Cherne Pipe Plugs for consistent performance. “We own an assortment of Cherne plugs that cater to varied pipe sizes from 200 to 600 millimeters,” Da Silva explains. They also use the Cherne Air-Loc Low Pressure Air Testing Control Panel to monitor compressor, plug and test pressure. Blocking plugs temporarily halt wastewater flow for thorough sewer line inspections, enabling accurate diagnostics and informed maintenance recommendations. Miller Underground uses Cherne 6- to 10-inch I-Series Test-Ball Plugs for air pressure testing in the Port Lands Flood Protection Project in Toronto, scheduled for completion in 2024. This project includes creating a naturalized river valley, new public spaces, roads, bridges and utilities.

Result: To ensure safe handling of Cherne pipe plugs, Miller Underground prioritizes training. “During our early stages, a Cherne representative trained us on proper use and safety guidelines,” says Da Silva. Employees follow rigorous protocols, from plug size selection to pressure monitoring, ensuring safe and efficient operations. Miller Underground consistently relies on Cherne pipe plugs for their durability and reliability, enhancing the efficiency and safety of their projects. 800-843-7584; www.cherneind.com
