Our Remote Manhole Water and Wastewater Level Monitoring Solution provides a comprehensive approach to efficient wastewater network management and critical infrastructure monitoring. By leveraging cutting-edge technology in 80 GHz non-contact radar level sensors, municipalities and utility providers can track, control, and optimize their collection systems in real time. The result is a future-proof solution that not only addresses current surcharging and environmental challenges but also adapts to the changing demands of urban wastewater management, ultimately protecting public health and natural ecosystems.
Connecting remote sewer channels and manholes to a central digital network transforms static, isolated underground assets into an intelligent infrastructure monitoring network. By feeding continuous sensor data directly to a cloud platform, site managers gain complete control over every manhole on their network while eliminating undetected blockages and surcharges that drive environmental pollution.
Asset Visibility
Continuous telemetry from heavy-duty, corrosive-resistant radar level sensors provides total operational oversight across every manhole location through a single, centralized dashboard. Instead of relying on manual, periodic physical checks that leave long gaps between inspections and expose technicians to confined spaces, teams receive live updates on liquid depth, derived flow rates, and network status. Automated high-level alerts immediately flag sudden rises caused by main line blockages, severe grease build-up, or storm-driven surcharges, allowing teams to respond instantly and dispatch maintenance crews before sewer overflows occur.
Resilient Operation
Continuous telemetry from IP68-rated radar level sensors provides total operational resilience across harsh underground sewer environments through a single, centralized dashboard. Built to endure aggressive hydrogen sulfide gas exposure, corrosive effluents, and temporary total submersion, the system maintains continuous data flow even during severe weather events. Automated threshold notifications instantly alert municipal operators to rising surcharge levels or rapid hydraulic spikes caused by heavy rainfall, allowing teams to execute emergency bypass pumping, redirect influent flows, and mitigate structural washout around the pad before infrastructure damage or public health risks escalate.
Compliance Assurance
Continuous automated logging from radar level sensors establishes an unalterable, audit-ready digital record of wastewater levels, hydraulic capacity, and surcharge events across municipal collection networks. By replacing sporadic manual logs with real-time telemetry delivered directly to the Ellenex Software Platform, utility operators can easily demonstrate environmental compliance with EPA regulations and local discharge standards. Automated high-level alerts provide immediate proof of response times during overflow events, helping authorities mitigate regulatory fines, simplify environmental reporting, and maintain strict adherence to public health guidelines.

Frequently Asked Questions
How does the Remote Manhole Water and Wastewater Level Monitoring Solution handle signal propagation from deep underground manholes?
The Remote Manhole Water and Wastewater Level Monitoring Solution is designed around a dual-LPWAN hardware architecture that utilizes sub-GHz radio frequencies (LoRaWAN) or licensed cellular LPWAN technologies (NB-IoT/LTE-M) specifically optimized for deep signal penetration. The system couples an IP68-rated, radar level sensor placed at the invert of the manhole with a surface-mounted or sub-surface transmitter enclosure. The LPWAN wireless protocols utilize specialized Chirp Spread Spectrum or extended link budget modes (+20 dB) to easily penetrate heavy cast-iron manhole covers and dense urban roadways, ensuring encrypted telemetry reaches the Ellenex Software Platform reliably without requiring expensive external antenna masts.
How does the system withstand exposure to aggressive gases and corrosive sewage inside wastewater networks?
The entire assembly is engineered using high-grade industrial materials built specifically for harsh, corrosive environments. The radar sensing probe features a heavy-duty, chemical-resistant body with specialized seals, and uses a vented polyurethane cable engineered to resist degradation from oil, hydrogen sulfide, and biological sludge. Furthermore, the electronics housing achieves an IP68 ingress protection rating, making it completely dust-tight and waterproof against continuous immersion during severe surcharge events, guaranteeing that the system remains fully operational and streams data to the Ellenex platform even when completely submerged.
What specific field installation steps are required to get the manhole monitoring hardware up and running?
The solution is built for rapid, zero-touch field deployment that requires no software setup, manual driver installation, or on-site device programming. A field technician simply secures the IP68 transmitter enclosure near the top of the manhole, lowers the pre-calibrated submersible level sensor to the invert channel using the durable cable, and activates the internal power switch. The device immediately connects to the nearest cellular tower or Ellenex LoRaWAN gateway, authenticates automatically, and begins streaming encrypted water depth and temperature metrics directly to the Ellenex Software Platform in less than five minutes.
How does this solution assist municipalities with inflow and infiltration (I&I) analysis during heavy rainfall?
By logging high-frequency liquid depth and derived volumetric flow data over long periods, the solution provides municipal engineers with detailed hydraulic modeling data via the Ellenex Software Platform. During storm events, the software correlates rapid rises in manhole water levels against baseline dry-weather flows, allowing utility operators to pinpoint exact network segments suffering from groundwater infiltration, cracked pipes, or illegal stormwater cross-connections. This enables targeted infrastructure repairs rather than costly, wide-scale pipe replacements.
Can battery life be maintained for up to 10 years in cold or off-grid subterranean conditions?
Yes, the hardware incorporates ultra-low power management firmware combined with a high-capacity, non-rechargeable 3.6V Lithium battery designed for industrial temperature extremes. The device stays in a dormant, ultra-low-current sleep mode for the majority of the time, waking up only at user-configured sampling intervals to take hydrostatic measurements and transmit encrypted payloads to the Ellenex platform. If an anomaly or high-water threshold is breached, the unit automatically alters its transmission rate to provide real-time updates, balancing long-term battery lifespans of up to 10 years with critical event alerting.
