The Challenge

Why Water Mains Fail Quietly.

The deterioration is invisible, the shutdowns are costly, and the record is missing.

01

Corrosion & Lining Loss

Internal corrosion, tuberculation and failed linings develop over years without a single visible symptom. By the time flow or pressure drops, the pipe wall is already compromised.

02

Shutdowns Cost More Than Repairs

Every hour a main is off supply costs far more than the inspection itself. Utilities need condition data without closing the line or interrupting supply.

03

No Condition Record

Without a structured survey history, maintenance is driven by failure rather than condition — and budgets are justified on guesswork instead of evidence.

04

Buried, Hidden, Hard to Reach

Water mains run under roads, river crossings and built-up areas. Digging trial holes to check condition is slow, disruptive and expensive.

Answer First

The direct answer.

How are water mains inspected without shutdown? For drainable, non-pressurised sections the practical answer is remote robotic CCTV: a tracked crawler enters the line at an access chamber or valve and drives through the pipe while cameras record the internal wall continuously. PipeSolv's K-Series does this in service wherever access geometry allows — no shutdown, no supply interruption and no excavation.

Condition that fails quietly

Water mains rarely announce their problems. Internal corrosion, tuberculation and lining loss develop below grade, invisible until flow, pressure or water quality changes. A robotic survey surfaces that condition early — capturing lining state, joint movement, deposits and early corrosion with enough clarity to separate routine ageing from developing faults.

A record your capital team can plan on

Every run produces continuous video, defect screenshots and a structured report with metered positions. Because each survey is repeatable, utilities can compare condition year over year, justify maintenance budgets with evidence, and move rehabilitation from reactive to planned — before a failure decides the schedule.

In the Field

In Service, On Record.

The K-Series inside the mains network — lining, joints and corrosion captured without a single hour of lost supply.

Pressure Mains, No Shutdown

Potable and utility mains are surveyed in service — no line shutdown, no supply interruption and no excavation to reach the pipe.

Corrosion & Lining Survey

Continuous HD footage captures corrosion, lining condition and joint movement years before a failure would surface.

Our Solution

The K-Series Surveys It In Service.

The K-Series is lowered into the network at a valve chamber or access point and driven through the line while it remains in service wherever geometry allows. Twin HD cameras capture the full wall — lining condition, joint movement, corrosion and deposits — while the electronic encoder pins every observation to a metered position. The result is a dated, objective condition record that asset teams can compare year over year.
