In 2019, IEUA first deployed two satellite sewer monitoring units to provide real-time, low-cost monitoring at sites that historically had encountered blockage issues across the collection system. The data collected allowed IEUA to identify potential blockages before an overflow occurred. IEUA has since expanded their satellite sewer monitoring program to 25 units which have saved at least four spills; thereby protecting public health and the environment, preserving overall authority resources, and preventing asset degradation.

Due to current conservation measures in southern California and the recent change in water usage put into effect from Senate Bill 1157 (2022), GPCD (gallons per capita per day) is being reduced from 55 to 42 by 2030. With the reduction of flow and ongoing population growth, there has been an increase in solids in the system and unpleasant odors from increased hydrogen sulfide (H2S). IEUA will be deploying two more units which will provide real-time, low-cost H2S monitoring at sites experiencing issues across the collection system.

Additionally, a fats, oils, and grease (FOG) build-up was identified at one of the monitored sites which allowed IEUA to run a successful marketing campaign to the area residents educating them about the importance of disposing FOG into the trash rather than down the drain. IEUA is also able to monitor industrial flows into the system utilizing the sewer monitoring units.

Learning Objectives:
Upon completion, participants will be able to understand the use of satellite sewer monitoring for blockage prevention.
Upon completion, participants will be able to understand the use of sewer monitoring to meet regulation challenges.
Upon completion, participants will be able to understand how sewer monitoring has influenced community engagement.
