Borehole CCTV Surveying

API offers borehole CCTV condition assessment surveys. These inspections include video, sound and distance data on new or existing boreholes enabling detailed inspection.

System set up:
A portable CCTV camera is lowered through a specially designed tripod configuration into the borehole, and is fully pressure rated enabling a visual subsurface inspection of the borehole structure, not only is this interesting for a geologist but extremely useful for an engineer; allowing them to spot problems and plan out potential fixes.

Reasons for Borehole surveys:

• Demonstrates the actual construction of a borehole, including the amount of casing installed and depth of the borehole
• Allows a hydrogeologist to see the underlying rock strata and where water is entering through fractures and fissures into the borehole
• Can give an idea on the quality of water in the borehole
• Periodic inspection gives the opportunity for an engineer to determine if the well construction is in good condition or well refurbishment is needed
• Gives a potential purchaser the opportunity to see the condition of the borehole or well that they are buying

If a borehole has a problem the CCTV survey will identify where and what the issue is, has the borehole got an obstruction? What depth this at and what type of obstruction can be identified.

API borehole surveys include the provision of a full colour recording of the borehole survey. The recorded data is also analysed post survey with the provision of a detailed data report provided. This information enables an engineer time to consider any further requirements. A permanent historical record of the borehole is provided which can be added to periodically, with a comparable report service also available.

Flushing Surveys MFE (maximum flushing efficiency)

Using pressurised CCTV technology has shown API that water flushing alone will not remove high levels of residual sedimentation in a pipeline. Engrained wall deposits and biofilms remain along with heavy sedimentation at the base of the pipe.
Millions of wasted gallons of treated flushed water is a common practise, as pipe flushing is an age old approach to controlling turbidity and cleaning pipes.

Wasted revenue on ongoing contractor flushing /repeated visits/fuel/environmental impact

API offers a unique pipe surveying and improved efficiency service which includes:

• Entry via Through bore fire hydrants
• Flushing port downstream can be via a standard or TB fire hydrant

Pipe Sediment and Sample Removal Service

API offers pressurised pipe inspection surveys to identify and locate debris and sediment within a pipeline, investigate DWI complaints and give the utility a better understanding of its network.

We also offer sediment removal from concentrated areas of concern, typically identified on pipe fittings, bends and joints. The unique service uses water pressure in the pipeline to expel localised debris and safe removal under controlled conditions.

System set up:

Combination camera system unit for the removal of debris within a pressurised potable water pipe

Sediment identified in pressurised water pipe         Removed sand/debris

Water is a valuable source around the world for many reasons; however lost water in the world of hydro is also a loss of energy and in turn revenue.

API can undertake live CCTV and acoustic inspections on all pipeline assets and offer clients a full data report to test the pipeline for:

• Corrosion
• Leakage
• Air pockets
• Negative pressure zones
• Hydraulic modelling
• Loss of bore through pipe inversion (common in plastics/MDPE)
• Debris and obstructions

Any of the above areas could reduce hydro output by a level of up to 50%, this in turn could see a revenue loss of millions of pounds to the operator.
API recommends a periodic test of hydro schemes every 3-5 years due to the natural aging process, change of climate and on-going corrosion and build-up of debris within the pipe line.

External Non Destructive Testing / Pipe work condition assessment

API offers the latest technology to scan external pipe work assets; from this we can measure internal/external pit depths, wall thicknesses, ageing and corrosion levels.
Utilising a specialist assessment system, an ultrasonic delivery driver is attached to the pipeline, the site technician measures the pipe circumference at this point and inputs the data into the software system. Ultrasonic probes are coupled on the pipeline and water jets immerse the probes during the scanning function and accurately measure the pipe wall thickness of the pipe.
The system then traverses the pipeline giving thousands of wall thickness readings for a detailed report production.

Additional tests are also undertaken on site including soil resistance levels, temperature and soil sampling.

This information is then processed by our data analyst utilising the data life expectancy is calculated. This is put into a full data report presented to our client in a paper/digital format.

Pipe In-situ Testing / Surface Replication

Acetate replication is an established technique in faithfully copying the micro-structure of a material on to a film. This means a material can be examined in a laboratory without sectioning or damaging the area of interest. This surface procedure is used to identify a material, look at the quality of a material or examine a particular area of interest such as a weld or joint.

A small area of the sample is prepared using a 600 grit paper, 120 grit paper and a cloth impregnated with a 1 micron diamond polishing paste. The area of interest is then etched to reveal the micro-structure. Once sufficient etching has occurred, a thin film of acetate film is applied using acetone, a spray and double sided tape. This process is finalised by adding the replica to a glass slide for examination under the microscope by our experienced analyst.

Existing Water mains

A large amount of water mains have been in service for many years, however through type of materials used, age of mains and backfill type these mains are now failing causing water loss, discolouration issues and eventually complete failure.
Through experience on pipe networks around the world, API has highlighted the fact that in most cases, it is actually the pipe joint that is failing prior to the pipe itself, and therefore would recommend an acoustic testing approach on the entire pipeline and on all joints, from this data the correct planning can be put in place with pre-determined points of interest being exposed and tested.
Many utilities do undergo a system of on-going monitoring of these assets, however the location chose to test is typically solely down to a pre-determined measured point on the pipe, or area with ease of excavation access.

The on-going testing of pipelines should be approached in the following order:

1. A full asset investigation and leakage sweep
2. Planning of true excavation locations from data obtained
3. External scanning of highlighted areas only (remove the guess work)
4. Internal scanning to cover further distances and highlight defects in difficult to access locations i.e. under rivers/roads etc.

A full asset investigation and leakage sweep

API offers a full service of pipe inspection and acoustic leak detection surveys to monitor internal condition within a live water pipeline. The surveys offer detailed analysis of pipelines with actual knowledge resulting in the correct course of pipe rehabilitation.

Ongoing Pipe Monitoring
Pipe locations with a frequent burst history, or for high risk locations ie river and road crossings. API can offer ongoing monitoring of these areas using a wide array of pipe inspection Technologies.

The installation of the Pipeline^TM in-line cabling system enables a rapid response to pipe inspection and leak detection without the need for any flow within a pipeline.

Planning of true excavation locations from data obtained

A full condition assessment can be obtained after post analysis of the live CCTV/Hydrophone inspections.
All visual and acoustic points of interest will be logged and highlighted prior to any excavations in order to maximise the overall value of external scanning by only testing where it is truly required.

---

External scanning of highlighted areas only

The highlighted areas of interest will be excavated and external testing of the main can be obtained from these trial pits (approximate 2 locations per day)
The main will be exposed, any lining material to be removed and then cleaned.
The system is attached to the crown of the pipe and is magnetically anchored to the asset, it then traverses around the asset 360 degrees stopping on its primary position with thousands of wall thickness readings obtained.
The main is then protected with a painted or taped covering prior to its backfill and reinstatement of surface coverings.

Conclusion
NDT Testing programmes are a pro-active approach to pipe failure, however is flawed due to lack of actual asset knowledge.
API offer the removal of guess work during the pipe testing of assets as only the highlighted areas are tested further to determine true pipe condition.
This approach does not only give the client a true understanding of asset condition, but also offers true pro-active approach to eradicate leakage, future catastrophic burst and also in time determines the correct capital spend on the right pipe areas.

API Pipe Testing Philosophy
Look – Undertake live CCTV surveys to determine the most corroded pipelines, check if pipes are lined and solve unknown pipe issues ie buried valves
Listen – Undertake live acoustic inspections to determine areas of leakage interest and identify pinhole leaks
Monitor – NDT testing and ongoing monitoring of high risk pipelines prior to failure

Pre Lining/Pipe Pulling Inspections Water and Gas

Much of the world’s drinking water pipeline infrastructure is long past its design life and in need of repair. Complete replacement of these pipes using conventional dig and replace solutions can be time consuming and very disruptive to traffic, the general public and the environment. These problems can easily be avoided by choosing to reline over replacement.
The cost of relining is still a costly approach and prior knowledge to pipeline configuration is required, as this will save companies many hours and days of downtime during the installation process, along with information required during the planning stages of the projects.
Another approach is butt fusion pushing of pipes within pipes (using the original pipeline as a host pipe). The same issues occur as for lining, along with the additional cost of added bends, valves and excavations.

To date API has undertaken pre lining inspection projects for Affinity, Anglian and Thames Water. This has resulted in saving contractors a vast amount of time and money by removing the guess work from these projects.

Water leakage recovery is often the best and most economical source to meet increased demand, compared to building or expanding treatment facilities.

New Water Mains/Failed Hydrostatic Tests

New installation of Water Mains

Modern pipeline materials have rapidly reduced the initial material cost, increased the rate of installation along with expected life expectancy. However there are associated issues with these products and therefore during installations fail safes should be put in place.

Leak detection

There are many technologies available on the market today, however these are typically material dependant, have size of main limitations, depth of main and surface material type is also an issue.

Traditional leak detection techniques:

• Correlators- These are not reliable or accurate on plastics and Large diameter Mains, and may result in dry digs through inaccurate noise logging
• Gas trace- Requires a porous land surface structure and not successful on Large diameter mains
• Listening sticks- Dependant on depth of main and land surface structure
• Ground microphones- As above

The latest leak detection technology
Insertion technology-This technology is inserted directly into the pipeline under standard operating pressure, this may be chlorinated for use in potable water networks.

The sensor head is navigated along the pipeline, and as it passes the leak, the trained operative can both see and hear what’s happening within the pipeline, and therefore detect leaks in all materials (hydrophone can detect the direct exit point of a leak).

This technology has now been proven to detect the most difficult to trace leaks in all pipe materials, irrelevant of depth of main and ground surface type or structure.

The latest leak detection and CCTV Technology
The PIPA range of products (Insertion Technology) – Live and pressurised CCTV/Acoustic surveys are undertaken on a length of pipeline to establish condition, configuration and leakage or failure points of interest. These systems can be used on all pipe sizes, materials and up to a distance of 2 km.

Design and Pre planning for insertion technology
During the design process of all pipelines there are several ways of pre planning for the possible use of insertion technology.

Fire hydrant type- The latest hydrant design is that of a through bore fire hydrant, these are open access hydrants that offer a 60mm bore direct port into the pipeline and in turn enables the use of insertion technology, CCTV Investigation along with flow meters and all other insertion technologies.
These are now being adopted throughout the UK by most of the Utility suppliers and are currently manufactured by AVK, Saint-Gobain and Viking Johnson.

Insertion and inspection chambers- Thames Water currently is proactive in Trunk main monitoring in the London area, by installing insertion access chambers on strategic pipelines for monitoring mains with a history of bursts or leakage, this approach should be adopted during the design stage on newly laid water mains as the cost would be sufficiently less during the new lay process.

The Pipeline™ in Pipe Cabling Product
Incorporating draw lines in the design stage of all new pipe installations, offer a simple but effective failsafe in case of any future pipeline issues.
The Pipeline™ is a unique cabling system manufactured specifically for in-line cabling of newly constructed pipelines. The product can also be retrofitted into existing pipes.
The 4mm galvanised steel polyethylene coated product is designed for long term exposure to chlorinated water, and designed for potable water pipe installation.
The cable is suitable for all pressurised and depressurised pipe installations.
The cable design is uniform to allow sealing plates to be installed onto the cable at either end in the event of a pressurised pipe inspection.
The cabling allows the pull through of leak detection, monitoring, cleaning and inspection technology in the event of a failed hydrostatic test or leak, or for routine cleaning or testing. This product remains in the pipeline as long as required.

Installation
The cable is installed into the pipeline during the pipe construction process (can also be retro-fitted), with strategic isolation points on the pipe. The cable is then held in place by the compression of a gate valve or fitting either end.

To retrofit into pipelines the cable is floated through a live water pipe and extracted through a secondary seal arrangement.

In the event of a pressurised technology pull through, the cable is passed through a seal arrangement and attached to a cabling device for the pull through of required technology. During this procedure a secondary cable is attached and in turn is pulled into the pipeline replacing the existing cable.

System Set upImage of cabling in pressurised pipeline pulling through a technology device

The isolation valves or fittings are opened either end, and the pull through technique is then undertaken. Once the pull through is complete, the isolation of valves or fittings is undertaken.
Utilising the Pipeline product is a way of future proofing and monitoring all high risk pipes or conduits.
Strategic installation is advised on pipes close to river crossings and train lines.
The unique product is supplied in 1km drums, however can be manufactured in lengths of up to 5km.
The product complies with DWI materials in contact regulations, and has a service life of 5 years.

Leak Detection Using Correlation

When a liquid under pressure escapes from a pipeline it creates a sound pressure wave (leak noise) which travels along the pipe from the exit point.
The velocity at which the sound travels within the pipe depends mainly on the pipe diameter and material.  Most leak correlators will use two sensors which are attached to the pipe on either side of the leak point (usually onto a hydrant using magnets).
To perform a correlation the user will input the distance between the two sensors, and the pipe material (if known) into the base unit.  Each sensor records the sound and transmits this data to a base unit, which measures the time difference between the leak noise signals arriving at each sensor. From this data, the base unit can calculate the precise location of the leak if present.
API utilise the most advanced and up to date correlators on the market today to resolve leakage issues in a wide range of pipe materials.
