What is a Drain Survey?
Drain surveys, also known as drainage inspections or CCTV drain surveys, are a method used to assess the condition and functionality of underground drainage systems. These surveys involve the use of specialised equipment, including closed-circuit television (CCTV) cameras, to inspect the interior of drains and sewer pipes.
What is the purpose of a Drain Survey?
The primary purpose of drain surveys is to identify any issues or problems within the drainage system, such as blockages, leaks, cracks, collapsed pipes, root intrusion, or other forms of damage. By visually inspecting the drains, surveyors can determine the cause and extent of the problem and recommend appropriate solutions for repair or maintenance.
What happens during a Drain Survey?
During a drain survey, a small camera attached to a flexible cable is inserted into the drainage system through an access point such as a manhole or an inspection chamber. The camera is remotely controlled and navigated through the pipes, capturing high-quality video footage and images of the drain's interior.
Examining the Drain Survey Footage
The recorded footage and images obtained during the drain survey are thoroughly examined, and a detailed report is generated. This report highlights the condition of the drainage system, identifies any existing or potential problems, and provides recommendations for repairs or remedial actions if necessary.
Who can do a Drain Survey?
Drain surveys are commonly performed by drainage specialists, plumbing professionals, or companies specialising in drain inspections and maintenance. They are particularly useful for homeowners, property buyers, commercial properties, and local authorities to assess the condition of drains, ensure compliance with regulations, and plan necessary repairs or upgrades.
