- Distinguishing production variance from corrosion
Existing tools to assess the actual status of extensive water distribution networks are limited. Too often, utilities are limited to using statistics, pipe sampling and modelling to predict breakages. Modelling often leads to
BIT provides data on the condition of every single pipe:
Measurements of remaining thickness
Quantifications of corroded pipe walls
- Distinguishing external from internal corrosion
Mapping of internal topography
- Presence of valves, branches, joints, repairs, etc.
On-board leak detection
- Matches leak noises with pipe topography
Recommendations for cost-effective and risk-reducing actions
Based on inspection data and main information about the pipeline (year of construction, nominal wall thickness, steel grade etc.) speed of corrosion is calculated, and
The report from the inspection includes:
Technical data on pipe and inspection
List of important findings
- Production variance for each pipe
- Internal/external corrosion
- Condition of lining (bitumen, not cement lining)
Analysis of the condition of each pipe
Summary and recommendations for actions
Flexible format – suitable for GIS import
BIT AS is at present the only company in the world that can deliver all these data without pre-cleaning the pipe and in a single scan operation.
The use of the BIT Report:
Prioritise pipes by urgency and action
- Which pipes are healthy?
- Which pipes can/should be lined?
- Which pipes should be replaced?
- Which pipes should be repaired?
- Cost/benefit/risk analysis
- Combine data with other sources/tools:
- Geographical Information Systems (GIS)
- Asset management tools
