SmartBall: Water Main Leak Detection and Pipeline Condition Assessment
SmartBall® can be inserted and retrieved from a pipeline under normal operation. The ball travels with the water flow for up to 12 hours, collecting information about leaks over many miles of pipeline with a single deployment.
The size of the SmartBall® selected for a specific survey is based on a number of criteria including the diameter of the pipeline, location of in-line valves, the size of the appurtenances through which the SmartBall® is inserted and retrieved, and the presence of other lateral lines. Typically, the SmartBall® will be less than one-third the diameter of the pipeline.
PipeDiver™ is a platform for free‐swimming inspections of large diameter water and wastewater pipelines. Surveys are conducted under live operating conditions, providing condition information with minimal disruptions to service.
The PipeDiver™ platform can be used for the condition assessment of multiple pipe materials by incorporating the appropriate technology. For PCCP and BWP condition assessment programs, PipeDiver™ is outfitted with the Electromagnetic (EM) technology. This technology detects broken prestressing wire breaks in PCCP, broken bars in BWP, as well as large holes or perforation in the steel cylinder.
Remote Pig Tracking Made Easy with Armadillo Tracks
Historically, pigs have been tracked by a team of field technicians who follow the pig from its launch to the trap, over the course of many days and nights.
For multiple-pig runs, more pigs in the line means more trackers are required, multiplying the problems faced by technicians out in the field.
In comes Armadillo Tracks by PureHM
Armadillo Tracks is an automated pig tracking and bench marking system that eliminates the risks of traditional pig tracking. Designed to be a much safer, reliable, and more cost effective system for operators and field technicians; Armadillo Tracks uses Remote Tracking Units, or RTUs, built to withstand extreme weather conditions.
Technicians and operators can get real-time SMS or Email updates of flow changes, stoppages, pig passages, launches or estimated arrivals.
Risk-Based Approach for Force Main Management
Historically, a comprehensive assessment of a utility’s wastewater assets has been challenging because a large piece of the puzzle was missing – how do we inspect force mains? Traditional inspection methods on gravity mains use visual assessment, which does not quantify the loss of structural capacity in force mains, the true indicator of imminent failure.
Today, the management of wastewater force mains is becoming a priority as regulations regarding their safe operations increase, and utilities seek a better way to manage their force mains to comply with these regulations.
Costs of undertaking a full force main replacement programs are very large. But full-scale replacement of the force main networks isn’t necessary if owners manage them using a risk-based approach. Doing this will identify which of their assets requires rehabilitation, which require replacement and which can continue operating safely in their current condition.
Forward-thinking utilities who have used this approach have safely managed their force mains for roughly 5 to 15 percent of the replacement costs by isolating areas of damaged pipe. Pure Technologies is a leader in performing this type of comprehensive risk-based assessments of force mains, using innovative technologies and expert data analysis.
Pure Technologies focuses on approaching force main management holistically. To achieve this, every aspect of a utility’s force main system needs to be investigated. This includes performing preliminary analyses, assessing the condition of the force main, and analysing condition data and performing a risk-assessment.
Preliminary analysis collects the data, prioritizes mains for assessment and determines the appropriate inspection technology based on risk level, pipe size, and composition.
Using inline and external inspection tools, an internal corrosion survey identifies and locates gas pockets that can cause corrosion and eventual breakdown of the pipe wall.
Pipe Wall Assessment or PWA, is a new technology that identifies stress spots on pipe walls. These indicators of stress can be from a number of factors including pipe defects such as cracking and wall loss, and external load factors on the pipe, among others.
Finally, condition data analysis and risk assessment evaluates how to safely renew or extend the life of force mains by looking at the likelihood and consequence of failure.
This approach shapes a comprehensive risk-based program for force main management that allows utilities to successfully manage their assets and cost-effectively comply with wastewater regulations.
