Using Saraha to locate gravity sewer for construction permission
WRc used Sahara® to locate a gravity sewer for a client in order for redevelopment planning permission to be granted by the water company.
A high-accuracy sonar and CCTV inspection tool used for pinpointing leaks and pipeline condition assessments.
Sahara® is an established and safe deployment method for a range of inspection sensors that can be used to pinpoint leaks in pipelines of any material and undertake pipeline condition assessment surveys. The Sahara® system can be used for the effective management of new and existing pipelines, which can usually be achieved in real-time while the pipeline remains in service, meaning no disruption is caused to your customers.
Sahara® can be deployed through a 50mm tapping (larger may be called for depending on specific equipment required), such as a through-bore hydrant or existing air valve. While there is no maximum pipe diameter for deploying Sahara®, the pipe diameter should be no less than 100mm.
This technique relies on the water flow to carry the sensor through the pipeline, gathering data as it travels. The Sahara® equipment is mounted on an umbilical cable which provides pipeline route tracing - constant, traceable location information through monitoring the length of cable deployed during a survey.
A unique feature of the system is the inclusion of a location sensor that allows any feature detected to be precisely pin-pointed and marked on the ground over the pipeline during the survey.
Our technologies are combined, allowing for condition assessment whilst tracing leaks.
Even the smallest of leaks can be found and therefore monitored and addressed.
Pinpointed leak and air pocket location through fully traceable technology.
Sahara® technology is flexible and adaptable, servicing all pipe types through a range of solutions.
