The Klamath Falls South Suburban Sanitary District encompasses roughly 10 square miles and serves a population of approximately 25,000 people in Klamath Falls, Oregon. SSSD owns and maintains over 100 miles of sewer pipe and over 1000 manholes. Most of the sewer mains were installed in the 1960’s and 1970’s.
One of the key focus areas for SSSD is the management of Inflow and Infiltration (I&). Excessive I&I can overwhelm a collection system’s capacity creating overflows. Climate change indicates more severe weather in the future. These changing weather patterns and frequency of severe weather is more and more relevant to sewer operators. I&I increases wastewater treatment plant flows unnecessarily increasing treatment plant processing costs.
SSSD started monitoring in 2012 by installing four initial monitoring units for a cost of $50,000 but, when the need arose for expanding our efforts to more locations, they required a more flexible, easy-to-install and cost-effective solution.
To address I&I monitoring expansion plans, SSSD designed a smart sewer system with SmartCover technology.
By leveraging SmartCover patented design and deployment, SSSD has been able to both expand I&I monitoring and enhance the granularity and detail of information compiled. SmartCover flexibility has proven to improve existing I&I monitoring processes at a much lower cost than the alternatives. Deployment is turnkey because no confined entry is required, allowing a collection system to get up and running fast without a lot of wasted staff time or traffic management.
SmartCover customized the solution to aggregate flow information from multiple locations, thereby enabling more flexibility to analyze relationships between sites and to better understand the dynamics within sub-basins.
It is anticipated that ROI on the first round of SmartCover deployment will yield better information on I&I and provide a more refined capital improvement decision making process, while also controlling costs and enhancing usage of valuable staff and resources.
