Septic tanks are onsite water treatment systems. Waste from a property’s sinks, toilets, and showers is passed through the septic tank, so that it can be broken down.
Most properties connect to a mains sewer line. However, septic tanks are used when connection to mains sewers is difficult or not possible. A septic tank is an underwater sedimentation tank that treats wastewater. They need to be emptied and regularly maintained.
Septic Tanks
Traditional septic tanks filter waste laterally, through 2 or 3 interconnecting chambers. More modern tanks are shaped like an onion and involve significant excavation work to install. These filter waste upwards, as opposed to laterally.
Water enters the tank through an inlet pipe. It then separates, with heavier, solid waste falling to the bottom. Fats, oils, and greases will rise to the top, creating a layer of scum. Water is then treated and exits through an outlet pipe into a drainage field. It moves through further pipes as it undergoes more treatment and breakdown processes.
CCTV Drain Surveys
Traditional drain systems also require regular maintenance in order to keep them free from issues. This is usually done with a CCTV drain survey. To arrange a CCTV drain survey Nottingham and the surrounding areas, specialists such as //www.wilkinson-env.co.uk/drainage-services-cctv-surveys-midlands/cctv-drain-surveys/nottingham/ will be happy to assist.
CCTV drain surveys use state-of-the-art cameras to view the inside of the drains and sewers, with no need for digging or excavation. These images can then be inspected for signs of damage, disrepair, infestations, or blockages within the system.
