The crisis we're solving

America's sewers spill billions of gallons
of untreated sewage every year
and the storms keep coming.

Every wet-weather event sends raw sewage into the rivers we drink from, the bays we fish in, and the beaches our kids swim at. Smart Sewers is the toolkit utility teams use to see it happen, find the source, and stop it.

Feature 01 · Video Playback

Watch your collection system respond to a storm in real time.

The most important feature in Smart Sewers. A GIS-based time-scrubbed visualization showing how rainfall, manhole levels, and capacity react across your basin — minute by minute.

From raw data to system intelligence.

Traditional SSES gives you a binder full of static numbers. Video Playback turns the same data into a living map you can scrub through — the way meteorologists scrub through radar.

Click any manhole during playback to see its level, baseline, percent change, the rainfall above it at that moment, related defects, and the recommended next action. The whole digital twin in one screen.

  • See where I&I enters — manholes pulse amber as wet-weather response exceeds dry-weather baseline.
  • Spot surcharge zones — pipe segments and capacity-constrained areas highlight in red as they reach critical levels.
  • Compare before vs. after rehab — rerun the same storm against last year's data to prove the fix worked.
  • Generate council-ready exports — a 30-second clip of one storm beats a 60-page report every time.

Five more features working together as a digital twin.

Each feature feeds the others. The sensor map informs the playback. The defect explorer correlates with the hotspot detector. Hydraulic capacity drives rehabilitation priority. The whole stack is one connected system.

Feature 02 · Sensor Network

Hundreds of sensors. One map.

Deploy iTracker level sensors at every manhole that matters. Cellular IoT data streams in at 1, 5, or 15-minute intervals. Live system health, missing-data flags, and battery status — all visible in one place.

This is what makes the digital twin real. Without dense sensor coverage, you're guessing. With it, you're watching.

Feature 03 · Defect Explorer

Every NASSCO PACP/MACP defect, connected to its consequence.

CCTV finds defects. The Defect Explorer tells you which ones matter. Cross-reference structural codes with sensor data, hydraulic surcharge, and overflow history — so the rehabilitation list is ranked by impact, not just severity score.

Search by code, severity, basin, pipe material, or upstream sensor anomaly. Click any defect to see the inspection video, the sensor response above it, and the cost-per-gallon-of-I&I-removed estimate.

Feature 04 · I&I Hotspot Detection

Pareto in pixels: find the 20% that drives 80%.

Smart Sewers auto-ranks every micro-basin by wet-weather response. The heatmap shows you the system's hotspots after a single rain event — sometimes after two or three storms for harder-to-isolate cases.

This is what makes the platform faster than traditional flow monitoring. You're not waiting eight months for a full study. You're seeing the hotspot before the next council meeting.

Low I&I Hotspot · 4 micro-basins · 78% of basin I&I High
Feature 05 · Hydraulic Capacity Layer

Stop wondering. Start modeling.

Smart Sewers feeds sensor data and defect intelligence directly into the hydraulic model. See which pipes surcharge first, which lift stations are at capacity, and which rehab projects buy you the most relief — before you spend a dollar of capital.

This is the answer to "do we really need the plant expansion?" Sometimes the answer is yes. Often it isn't. Either way, you'll have the data to defend the decision.

Feature 06 · Smart Sewers AI Assistant

Ask questions. Get answers with citations.

The AI assistant has read every defect record, every sensor reading, every rainfall event, and every rehab work order in your system. Ask it anything in plain English and it answers with the data, the location, and the source it used.

This is how a director gets council-ready answers in 30 seconds — and how a field crew gets a ranked investigation list before they leave the truck.

Which manholes had the largest level increase during the March 12 storm?
Three manholes in Sub-basin 04 showed wet-weather response over 3× baseline: MH-247, MH-248, and MH-251. Combined I&I contribution: ~12,400 gallons over the 4-hour storm window.

Which of those have known PACP defects?
MH-247 → 248 has an FL 5 (Fracture Longitudinal) on the 8" VCP between them — coded in the November 2025 CCTV inspection. MH-251 has no current defect record. Recommend smoke testing MH-251 next dry day.
