Sahara Wastewater
Over the last 20 years inspection technologies and protocols for gravity systems have been well developed and adopted around the world. However, the same can not be said for pressurized systems. The challenge for the inspection of pressurized systems is that most inspection technologies require the line to be taken out of service. Often this is not possible due to the lack of system redundancy.
SaharaŽ wastewater is the first service to allow utilities to assess the condition of critical wastewater forcemains and siphons, such as major non-redundant lines, waterway crossings, and lines through environmentally sensitive areas, while keeping the line in service.
A series of pilot studies conducted across North America in 2006 have been held to demonstrate that the SaharaŽ leak detection system can be adapted to detect leaks in pressurized wastewater forcemains and siphons under typical North American operating conditions.
Sahara Wastewater can operate in most wastewater forcemains and inverted siphons. The lines must have sufficient flow speeds to pull the sensor through the line, and must have sufficient pressure to ensure that any water escaping from the pipe generates the acoustic signature recognized by the system.
