The Challenge

Why Manual Sewer Inspection Fails.

Manual inspection of these networks carries real, compounding costs.

01

Confined-Space Risk

Sewer manholes and mains are permit-required confined spaces. Entry means gas testing, permits, PPE and a standing rescue plan — and any one of those can stall a survey for a day.

02

Slow Mobilisation

Manual CCTV setups need multiple crew members and heavy cable reels. Small crews, long lead times and limited traffic windows make reactive surveys painfully slow.

03

Hidden Defects

Cracks, deformation, corrosion, sediment, root intrusion and joint displacement stay out of sight until they surface as a blockage or a collapse.

04

No Objective Record

Hand-written logs vary between operators, so comparing condition year over year — and justifying maintenance budgets — becomes guesswork.

Answer First

The direct answer.

How do municipalities inspect sewer pipes? The standard method is remote CCTV inspection: a small tracked robot is lowered into a manhole and driven through the pipe while cameras record the wall continuously. PipeSolv's K-Series does exactly this — without confined-space entry, without flow stoppage, and with metered distance on every frame so defects are reported at exact positions.

Non-invasive, no excavation

Sewer inspection is a visual survey: the robot records the condition of the pipe wall, joints and manholes without digging, without shutting the line and without people entering the network. The result is an objective, timestamped record that can be compared year over year to plan maintenance and justify budgets.

What the data looks like

Every run produces continuous video, defect screenshots and a structured report. The operator flags cracks, deformation, corrosion, sediment, root intrusion and joint displacement on the live view; the encoder pins each defect to a metered position along the run, giving the network owner a clear priority list for rehabilitation.

In the Field

Working the Line, End to End.

The K-Series on the invert and at the manhole — engineered from real field conditions, not brochures.

No-Entry CCTV, Right on the Invert

The robot is lowered into the manhole and driven through the live sewer line while cameras record the full wall. No entry, no excavation, no flow stoppage — just continuous metered footage.

Metered Defect Mapping

An electronic encoder logs distance on every frame, so cracks, deformation and root intrusion are pinned to exact metered positions for the maintenance team.

Our Solution

The K-Series Inspects It — No Entry Needed.

The robot is lowered into the manhole on its cable and driven through the line by a single operator on the surface. Twin 5MP cameras capture the pipe wall front and rear while an electronic encoder logs distance on every frame — so every defect is pinned to a metered position, not an estimate. The run produces continuous video, defect screenshots and a structured report, ready on the tablet at the end of the survey.
