Wastewater level monitoring

Every sanitary sewer overflow (SSO) is a regulatory event, a public health risk, and a costly emergency. For utilities managing ageing wastewater networks under growing demand, the challenge isn’t just responding to overflows, it’s preventing them.

• EPA consent decrees and NPDES permit obligations demand measurable SSO reduction
• Inflow and infiltration (I&I) silently increases network load and treatment costs — invisible without monitoring
• Unmanned pump stations, manholes, and overflow structures can surcharge undetected for hours

Combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) are among the most closely regulated challenges facing US utilities today. EPA consent decrees, NPDES permit obligations, and increasing public scrutiny mean that utilities need more than reactive responses — they need the data to demonstrate proactive management.

Kallipr’s non-contact radar sensors give utilities continuous, real-time visibility into sewer levels at the sites most at risk of overflow. By detecting rising levels and surcharge conditions before they reach overflow point, operators can intervene early, protect waterways, and build the data record needed to support regulatory reporting.

• Early surcharge detection — monitor sewer levels continuously and receive alerts when levels approach critical thresholds, before overflow occurs
• CSO event documentation — capture timestamped level data that supports EPA reporting requirements and consent decree compliance
• SSO reduction — identify high-risk sites and blockage patterns across your sanitary sewer network to prioritise maintenance and reduce overflow frequency
• Remote visibility — monitor unmanned overflow structures, manholes, and lift stations without requiring site visits or confined space entry
• SCADA and platform integration — route level data and alerts directly into your existing control systems for seamless operational response

Whether you’re managing a consent decree, responding to an EPA audit, or building a proactive overflow reduction programme, Kallipr gives you the monitoring foundation to act on data rather than incidents.

Inflow and infiltration (I&I) is one of the most costly and difficult problems in wastewater network management. Stormwater entering sanitary sewers through cracked pipes, faulty connections, and manhole covers pushes network capacity beyond its limits, increasing treatment costs, accelerating infrastructure wear, and raising SSO risk.

Kallipr’s continuous level monitoring reveals the I&I signature: level rises that correlate with rainfall events across specific parts of your network. That pattern tells you where the problem is, how severe it is, and where to direct your rehabilitation budget.

• Identify high-infiltration catchments without costly manual inspection programmes
• Build the data record to justify capital investment in pipe rehabilitation
• Monitor the impact of rehabilitation works over time to confirm improvement
• Correlate level data with rainfall data in Kallipr Kloud for automated I&I reporting
