Waste Water Pipeline Inspection: Signs of Damage

Waste water leakage is a major problem that causes significant health threat to area residents, pets, wild animals and flora and fauna of the affected area. Each year, the Environmental Protection Agency (EPA) estimates that approximate 3 to 10 billion gallons of raw sewage leak from the 1.2 million miles of waste water pipelines that stretch across North America.

Exposure to raw sewage can cause serious illness's such as Typhoid and significant damage to plant species that are vulnerable to bacterial growth. These dangers make taking proactive measures to prevent spillages and repair damaged lines a core responsibility of pipeline operators. Ideally, regular inspections will help alert your crew to any cracks or faults before a leak ensues. If you have never assessed the condition of your gravity or force mains, here is a quick guide to the steps required:

Step-1: Use soft foam pigs to clean the line of debris and scale

Step-2: Provide access for PICA's Tool through a pig launcher and receiver, or drain the line, excavate at both ends and remove a piece of pipe to provide access to PICA's winches and winch lines

Step-3: PICA will run our gauge Tool through the cleaned line to ensure there are no tight spots

Step-4: PICA will run its SeeSnake Tool through the line section

Step-5: put the line back into service

Step-6: PICA analyses the data, off site, and produces a report

Step-7: Schedule for surgical repairs, partial relining or replace sections of the inspected length that are seriously degraded.

The line should be scheduled for a re-inspection, depending on its condition, within 1-5 years.

Sleep well at night, knowing that your pipeline is back in good, reliable condition (and will be for many years).

PICA is an industry leader when it comes to the assessment of pipelines throughout Canada and the USA. Contact our team of experts to find out more today.
