Municipal Corporations & Urban Local Bodies
Water & Sewer Utilities — Inspection, detection & location solutions for urban infrastructure.
Inspection Solutions for Water & Sewer Utilities
Municipal corporations and urban local bodies face the challenge of managing ageing underground infrastructure — water mains, sewer networks, and stormwater drains — often without accurate records. Aerica Engineering supplies purpose-built inspection and detection equipment that helps utility teams survey, diagnose, and maintain these critical assets with minimal excavation and disruption.
Pipe Locator
How It Works
A Pipe Locator uses electromagnetic signal transmission and detection to accurately trace the path and depth of buried pipes, cables, and conduits. The transmitter induces a signal onto the target pipe — either conductively (direct connect), inductively (clamp or aerial), or via a sonde inserted inside the pipe. The receiver then detects the signal emitted along the pipe's length, allowing the operator to walk the surface and map the underground route in real time.
Key Features
- Locates metallic and non-metallic pipes up to 6 metres depth
- Multiple frequency modes for congested utility environments
- Active and passive signal detection modes
- Depth and current measurement displayed on screen
- GPS-enabled models for GIS data integration
- Suitable for water mains, sewer laterals, gas lines, and telecom ducts
Municipal Applications
Ideal for municipal corporations mapping aging water distribution networks, identifying unknown pipe routes before excavation, and preventing accidental strikes during infrastructure projects.
Robotic Crawler
How It Works
A Robotic Crawler is a self-propelled wheeled inspection vehicle deployed inside large-diameter pipes. The operator lowers the crawler into a manhole access point and remotely drives it through the pipeline, capturing continuous HD video of the pipe interior. The system is ready to inspect within 30 seconds of power-on and handles pipes from 1.25" to 60" in diameter. The crawler transmits live video to a surface controller, where the operator records, annotates defects, and generates condition reports.
Key Features
- Inspects pipe diameters from 1.25" to 60"
- 12.1" daylight-readable screen on surface controller
- Full-day rechargeable battery — no mains power required
- WiFi-enabled: share reports via email or cloud storage
- USB, HDMI, and ethernet connectivity
- Modular, portable design — deployable in under 30 seconds
- Integrates with GraniteNet software for standardised condition scoring
Municipal Applications
Used by ULBs for condition assessment of main sewer trunk lines, stormwater drains, and large-diameter water mains. Enables pre-lining surveys, post-repair verification, and routine maintenance inspections without disrupting traffic or excavating roads.
Water Leak Detector
How It Works
A Water Leak Detector uses acoustic correlation and ground-surface listening technology to pinpoint leaks in pressurised water mains without excavation. When water escapes through a crack or joint failure, it creates a distinctive acoustic signal that travels along the pipe wall and radiates to the surface. The detector's sensitive ground microphone captures these vibrations; advanced digital signal processing filters out ambient noise and correlates readings taken at two access points to calculate the precise leak location.
Key Features
- Acoustic correlation pinpoints leaks within ±0.5 m accuracy
- Works on metallic and plastic (PE, PVC, DI) pipes
- Operates on pressurised water mains — no shutdown required
- Digital noise filtering for busy urban environments
- Lightweight handheld ground mic for surface scanning
- Stores multiple readings for office analysis and reporting
- Covers pipe diameters from 50 mm to 1200 mm
Municipal Applications
Critical for municipal water utilities managing Non-Revenue Water (NRW). Enables leak survey teams to systematically cover distribution zones, identify active leaks in mains and service connections, and prioritise repair work — reducing water loss, energy costs, and road disruption.
Manual Pipe Inspection Camera
How It Works
A Manual (Pushrod) Pipe Inspection Camera uses a flexible fibreglass push-rod to feed a self-levelling camera head into pipes up to 12 inches in diameter. The operator pushes the rod from a manhole or cleanout, advancing the camera through bends and joints while viewing the live HD image on a portable controller. The system records the full survey, logs defect observations, and generates a condition report — all from a single rugged handheld unit.
Key Features
- Camera inspects pipes from 4" to 12" diameter
- 10.1" TFT full HD display with daylight visibility
- Up to 7.5 hours battery life on a single charge
- 128 GB internal memory — records 90+ hours of video
- Full QWERTY keyboard with IP55 ingress protection
- WiFi connectivity: stream live video to client phones or tablets
- Multilingual menu support
- Integrates with GraniteNet software for condition rating
Municipal Applications
Widely used by municipal field teams for inspecting house connection laterals, small-diameter water service pipes, and drainage connections. Compact and lightweight enough for single-operator deployment — ideal for routine maintenance checks, blockage investigation, and pre-repair surveys.
