CCTV Drainage Survey
When examining the condition of a drainage system takes place with the help of camera setup, that process is a CCTV drainage survey. It is possible to record video footage and capture other useful data during this procedure. It is essential for the inspection and survey of underground drains and sewers. This process is fast, safe and cost-effective. The use of it is also becoming popular in inspecting rainwater downpipes, vertical chutes and ducting systems. It is possible to gather a range of data through our CCTV drainage surveys. This helps a client to plan urgent repair or rehabilitation of pipes.
It also supports a planned preventive maintenance (PPM) programme that includes:
- A detailed map of the drainage system
- The lengths of pipes
- The flow rates and flow directions along pipes
- A measurement of the gradient along the pipe, known as pipe falls
- Location of defects in pipes, along with HD videos
GPS and GIS Installation
There is much importance of GPS/GIS applications in managing wastewater system. The GPS/GIS systems help in efficient mapping, monitoring, modelling and maintenance of the sewer lines.
The following are some of the benefits:
- It makes the existing maps of the sewer system more accurate by proper verification and correction of the sewer system components.
- It helps to create new sewer system maps if there are none.
- It solves the purpose of collecting sewer system attributes for increasing the GIS database.
Collecting both the location (coordinates) and the attributes data is possible with the help of GPS. There are graphic features and labels in the GIS database of the sewer system, with links or pointers to related attribute or tabular data. It involves organizing the features into a series of vector layers that contain points, lines or polygons registered to geographic control framework and a set of base information known as the base map.
