To transport the flow and avoid clogging, the drain or sewer 2 2000 00000 to that of the ground floor must generally be at least 0.8m lower. If it`s less, you should seek advice from a builder, architect, or drainage engineer. When expanding your property, you need to make sure you know if there are any water pipes, public sewers, or drains on your property. It`s a good idea to know this before you start so that the work runs as smoothly as possible. The location of rainwater pipes, sanitary piping chimneys and outdoor gutters can indicate where their underground drains are likely to operate. Pipes should be designed for water flow to minimize the risk of clogging and allow for air movement. For more information about pipe sizes, see the approved H document. Sanitary pipes should be ventilated to prevent air from escaping from pipes and drains in the building. It is highly recommended to seek advice from a builder, architect, drainage engineer or building authority before committing or starting work. In order to avoid an increasing risk of flooding elsewhere, it is best to tilt them towards a permeable soil or made of permeable materials. Permeable materials include both porous materials (p.B such as steel grass or gravel, porous concrete or porous asphalt) and permeable materials (p.B clay bricks or concrete blocks that allow water to flow through joints or cavities). This not only minimizes the environmental impact, but also avoids the cost of drainage.
Lazy drainage carries the water used from toilets, sinks, sinks, bathrooms, showers, bidets, dishwashers and washing machines. Surface piping is called sanitary piping; underground pipes are called rotten drains and lazy sewers. Additional rainwater pipes may be discharged into the ground or into new or existing underground pipelines. If you choose to drain rainwater pipes to the ground, you need to make sure that the water does not damage the foundation (for example. B by encouraging it to extend over a wide area) or does not flow to neighbouring properties (e.B. . . .
