Efficiency and Control of Water Networks
Overflow events at pumping stations, manholes, and collectors are among the most costly operational risks for water utilities. When a critical point in the network exceeds its capacity without warning, the consequences are immediate: flooded roadways, contamination of water bodies, damage to road and electrical infrastructure, and exposure to penalties from environmental and civil protection authorities. Traditional detection methods—based on inspection rounds or citizen reports—arrive too late: by the time the alert is received, the event is already underway.
Anticipating these events requires first understanding water level behavior at each critical point. Level sensors—ultrasonic, radar, or hydrostatic pressure—installed in pumping stations, manholes, collectors, and tanks transmit real-time data through a local RTU via cellular network, radio, or fiber optics to a central SCADA platform. Instead of reacting after water has already overflowed, the utility receives automatic alarms that enable contingency protocols to be activated before the event occurs.
The operational impact is measurable: every early alert reduces response time from hours to minutes, decreases damage to infrastructure and roadways, and avoids costs associated with environmental remediation and regulatory penalties. In addition, every monitored event is logged as historical evidence, useful for audits, claims, or regulatory review processes.
Utilities that invest in flood monitoring not only reduce their immediate operational risk; they build a historical database of water levels and event frequency that supports future decisions on investment, hydraulic infrastructure prioritization, and long-term contingency planning.
Overflows at pumping stations, manholes, and storage tanks are among the most costly — and most preventable — operational events for a water utility or a municipal public works department. When water level exceeds a structure's design capacity without a prior alert, the result is typically street flooding, damage to homes, contamination of receiving water bodies, and, in many cases, regulatory penalties. A well-designed monitoring solution turns this risk into a manageable event, with minutes or hours of advance warning instead of a reactive response.
How it works.
The solution installs level sensors at each critical point in the network: pumping stations, manholes in strategic collectors, and regulation or storage tanks. Measurement technology is selected based on the application — ultrasonic and radar for non-contact measurement in environments with solids or foam, hydrostatic pressure for deep or hard-to-access wells — and connects to an RTU that processes alarm thresholds locally. When a critical level is reached, the RTU immediately transmits the alert over cellular, radio, or fiber to the central SCADA system, which can in turn generate automatic notifications to on-call teams via mobile messaging or email.
Business value.
Early detection allows reinforcement pumping to be activated, flows to be diverted, or crews to be mobilized before an overflow occurs, significantly reducing remediation costs compared to responding after the fact. Historical data on level and event frequency at each monitoring point also supports investment decisions for expanding hydraulic capacity, prioritizing public works where actual risk justifies it.
Operational benefits.
Beyond reducing material damage, this solution shortens on-call response times, reduces reliance on physical inspection rounds, and generates an auditable record of each event — start time, duration, peak level reached — useful for citizen claims or environmental audits.
Technology overview and integration.
Level monitoring integrates natively with SCADA platforms and data historians, and can be complemented with rain gauge stations to correlate rainfall events with network behavior. Through APIs, the data can feed asset management systems (CMMS), geographic information systems (GIS) for territorial risk visualization, and Business Intelligence platforms for executive and regulatory reporting. Communication is secured under industrial cybersecurity schemes that protect the integrity of critical alarms.
Typical applications.
Level monitoring at stormwater and sanitary pumping stations, overflow detection in trunk collector manholes, level control in regulation and storage tanks, and monitoring of urban areas with a history of flooding for early activation of civil protection protocols.
Future scalability.
A point-based monitoring architecture expands naturally into a watershed- or city-level flood risk management model, incorporating predictive hydraulic models and AI-driven analytics that anticipate network behavior under different rainfall scenarios.
