SHELTER FROM THE RAIN
Miles Crossing, Oregon, United States
THE CHALLENGE
Miles Crossing’s shift to a vacuum sewer system was driven by rising septic system failures, compounded by its flat, below- sea-level location between the Youngs and Lewis and Clark Rivers, challenging traditional sewer solutions and necessitating innovative management
of inflow and infiltration.
The decision to convert to a vacuum sewer system was prompted by the escalating number of septic system failures attributed to the area’s unique topography. Miles Crossing, nestled between the Youngs River and the Lewis and Clark River, faced the dual challenges of being both flat and situated below sea level.
These geographical characteristics posed significant obstacles to the installation of traditional gravity-based sewer systems. Additionally, rain events exacerbated the strain on the system, leading to operational overload and increased costs. Addressing these challenges required a proactive approach to managing inflow and infiltration while maintaining the integrity of the community’s infrastructure.

The proactive approach to infrastructure planning and expansion lays the foundation for sustainable and resilient community development.
IMPROVED ENVIRONMENTAL PROTECTION.
The implementation of Flovac monitoring tools not only enhances operational efficiency but also contributes to improved environmental protection and sustainability. By effectively managing wastewater flows and minimizing inflow and infiltration, Miles Crossing reduces its environmental footprint and safeguards groundwater quality. The advanced monitoring capabilities of the Flovac system enable operators to detect and address potential environmental risks promptly, preventing pollution and mitigating ecological impacts. Through responsible stewardship of natural resources and ecosystems, Miles Crossing demonstrates its commitment to environmental preservation and ecological health.
THE FLOVAC SOLUTION
Initially, Gifford and Smith tried using individual pit-fire counters to track when a property’s vacuum pit was activated, but this method was costly and ineffective for pinpointing issues. They soon discovered FLOVAC, a globally recognized company in vacuum sewer system installations.
FLOVAC offered Miles Crossing a telemetry system that could connect to each vacuum pit, providing detailed data essential for identifying and addressing their infiltration and inflow (I&I) problems.
This monitoring system utilizes a sensor attached to the valve body, detecting the movement of a magnet every time the valve opens and closes, and measuring how long it stays open. Given that vacuum valves activate every 10 gallons of effluent, the system can estimate the volume of flow based on valve activations. High volumes of water, indicated by longer valve openings, can pinpoint excessive inflow at specific sites, allowing for targeted investigations.
With the new FLOVAC Monitoring System (FMS), operators can now monitor the entire system in real-time, tracking activations and durations for individual properties. This technology is particularly useful during rain events, as unusual patterns, like a home firing thousands of times in a day, can immediately signal issues, allowing swift on-site responses.
One notable issue identified through this system was a property with a damaged lateral pipe running under a driveway, which inadvertently channeled surface water directly into the sewer system. Through the use of CCTV cameras, the team documented the damage and collaborated with the homeowner to devise a repair plan.
In terms of infrastructure adjustments, Miles Crossing installed wireless telemetry equipment on utility pedestals along roadsides due to the area’s flat terrain and metal manhole covers, using advanced Gateway, Bluetooth, and LoRaWAN technologies integrated into the district’s SCADA system. This setup enables remote monitoring and sends alerts for any abnormalities.
Since implementing the system, maintenance has been minimal, typically requiring just an annual inspection. Nearly 60{f2ac4d1e1d40dc2e2d9280a1dfa90d854b2d8c80eba743affa37fc4ce2e16def} of the sewer system now has telemetry monitoring, with plans to expand this to the entire network. This proactive approach not only reduces field time and treatment costs but also enhances the system’s overall efficiency and sustainability, ensuring its long-term performance for the community.

THE RESULTS
The implementation of the Flovac monitoring system yielded tangible results for the community of Miles Crossing.
By detecting and addressing excess water inflow during rain events, operators were able to minimize operational disruptions and reduce the burden on the sewer system.
Through the identification and removal of unnecessary
tie-ins, the community achieved greater operational efficiency and cost savings.
Looking ahead, plans for a complete system rollout with Flovac monitoring technology promise to further enhance the sustainability and performance of Miles Crossing’s sanitary system, ensuring a bright future for the community.
advanced data analytics enabled precise monitoring of pit fires and rainfall correlation, which enhanced response efforts
“We’re able to generate 30-day reports of when pits are firing, the levels, and overlay the rain data. When we see a big spike in a rain event on the graph and it is over the top of a spike in pit fires, we know we have additional water coming in due to the rainfall, and address it,”
