CCTV Inspection using . The only means of documenting the condition of the pipes are by making a thorough inspection work by using the CCTV inspection system.

WinCan is an easy-to-use reporting package that gives professional, clear and concise reports, which can be customized and the reports include photographs captured directly from the survey video. These record video clips are recorded and saved for future reference to help provide evidence of incidents such as water ingress, joint displacements, corrosion and the general state of the sewer line. Detailed analysis and reporting of defects plus the ability to do post rehabilitation surveys. "Before" and "after" photographs can be printed together as evidence that repairs have been carried out correctly.

The latest high pressure water jetting units are used for fast, effective drain and sewer cleaning and blockage clearance. We clean sewers of all sizes and our HGV mounted machines have full acoustic bodies to minimise noise levels, scale, roots and cement based deposit can be cut through, using our fleet of jetting units with the latest rotating water jet cutting heads.

CCTV Survey:

From standard surveys to the most difficult inspection operations we have the experience and equipment to provide the answer to our clients needs.

Pipe Bursting:

Hydraulic Pipe Bursting is an innovative and cost effective method for the replacement or up sizing of broken or undersized drains and sewers. As the system is designed to work from within existing manholes, it can provide the ideal solution to replace a damaged pipe with little environmental impact.         more >>

Leak Detection in Drinking Water Lines:

When water pipes are old and in poor condition leakage can cause problems such as flooding, loss of water pressure and costly waste from the distribution system. Envirotech is able to undertake water leak detection and location (i.e. non-visible, below ground losses) using water industry standard practice including pipe tracing, step testing, transfer testing, top sounding and real time multi-point correlation.

Personnel are given special training on the operations by specialist in this line.

Pipe tracing is undertaken using Radiodetection Genny and flexitrace locators. These use a variety of techniques to detect and map underground pipework, in particular the generation of a radio signal that is transmitted through the pipework which is then picked up by the detector enabling a very accurate identification of the location of underground asset. Pipework buried at depths of up to 3 meters can be detected using these methods.

Step testing involves the isolation of discrete zones, then the monitoring of the variation of consumption within these thus enabling the particular zone(s) with the leak to be identified and isolated.

Transfer testing through the revision of supply arrangements, changing zonal areas in conjunction with step testing. This activity aids the process of leak location by positional iteration. This is particularly useful where the zones cannot be easily separated.

Top sounding - standard industry techniques using sounding and listening equipment. This ranges from the simplest technique that involves the use of a sounding stick pressed to the engineer's ear through to more sophisticated electronic detection systems using both noise and heat.

Correlator Reference Unit

The Correlator Reference Unit very accurately generates short and long time delays to check the correlator leak position indication. It also tests the sensitivity of the correlator by simulating strong, medium and weak leak noises

• Accurate time delay standard
• Simulates strong, medium and weak leak noises
• User can check this system for maximum confidence

Leak detection is a serious business

When water pipes are old and in poor condition leakage can cause problems such as flooding, loss of water pressure and costly waste from the distribution system. Envirotech is able to undertake water leak detection and location (i.e. non-visible, below ground losses) using water industry standard practice including pipe tracing, step testing, transfer testing, top sounding and real time multi-point correlation.
