API was recently contacted by a private customer regarding the loss of water supply to a newly built commercial coffee house property in the Bradford area of Yorkshire, UK.
The client had investigated outside the property however the pipe supply runs through a fully reinstated tarmac carpark and block paved area. The property had experienced very low water pressure which was an issue due to the nature of the business.
API offered a solution by using the brand new PIPA Hydrocam CS system. The camera entered the 32 mm diameter water pipe via a removed stop tap inside the building, and quickly identified the issue being a pipe blockage from pipe ingress.
A key hole excavation quickly exposed the blockage location and minimal damage was caused to the property and surrounding area.
PIPA developed a brand-new camera system in 2022 for small diameter services pipes called the Hydrocam CS. The unique system is supplied with a mini cable drum, 50 m of flexible trace cable, a 14 mm diameter pressure rated camera and battery powered control box.
The survey was undertaken within 30 minutes and pipe issues were identified. The camera was then used as a pipe trace system to identify the sensors exact location.
The pipeline was also surveyed from outside the building to check the remaining pipe area, additional pipe ingress was identified along with a joint fitting.
PIPA Hydrocam Technology
API uses PIPA technology that includes a 14 mm diameter pressure rated camera (Hydrocam CS) tethered to a 50 m semi rigid rod to give the operator live video and recorded data during an inspection. The system enters a pipeline via a standard inline fitting or inline boundary box, and is fully chlorinated during its insertion. The system works on a live basis, with no interruptions to the client’s services and with several surveys undertaken this unique product can cover up to 8 surveys per day.
The technology is the latest live main inspection system on the market being fully battery powered and only requires a 1-person team for its implementation.
PIPA has also developed reporting software to quickly present the results in a detailed data report document.
The survey results included:
- API successfully inspected the 32 mm diameter pipe using Hydrocam CS camera system
- API located the pipe blockage below a kitchen WC washroom area within the building
- The survey was undertaken at night due to the silent operation of the camera system, the coffee house had no shutdown to its daily business operation
- The contractor was able to resolve the issue with minimum property damage
- Tethered insertion technology system allowed for precise pipe assessment to give the client data including visual condition assessment, confirmation of material, lining and i.d. of pipes
- It offered a true no dig solution saving large excavation work and also saving time with guesswork
The Hydrocam CS is a QC tool and commissioning solution on all pipe installations new and old
It would have been very difficult and expensive for the contractor to excavate. The plan was to start excavation outside the building and expose the entire pipe, and then remove floors and wall space areas on further pipe investigations within the building.
The Hydrocam CS camera is now commercially available globally offering a trenchless pipe assessment solution to the industry.
An API representative said: “The project was a great success, and also a great case study for our company. The contractor had exhausted all other pipeline inspection avenues, and was more than relieved when we offered a solution.”
API has also delivered successful projects with the majority of the UK water utility companies, and many other projects overseas.
Feedback from the client said: “I am very happy with API for solving our problem so quickly. I searched on the internet for other companies in the service pipe inspection area, but nobody could offer a camera survey on such a small pipe! The bonus was this is approved on drinking water pipes. Luckily the camera found the issue was close to its entry point within the building, we were previously discussing digging up the entire ground floor and car park around the property! We were also disappointed to see a pipe joint as this could easily have been a 1 pipe run section, however we know where it is if we have any future issues thanks to API. Many thanks API for a great professional service and you quickly found it!”
