Building on top of an existing sewer or sewer can damage pipes, so they leak or block, which can lead to odour nuisance, health problems and environmental damage. It also makes it more difficult, time-consuming and expensive to eliminate constipation and repair or replace defective effluents. Therefore, if an existing flow is below or near your proposed extension, it may require deferral or protection, which will likely increase the cost of your project. If you want to know more, our detailed instructions are a good start. They will help you identify if and what type of consent you need. You must then submit either a declaration of work form or a request for a formal agreement. If you intend to build on top of or near a public sewer, you will need a written agreement from your sanitation company, so you should consult the company during the first planning phase of your work. The path of the flow should prevent obstacles (for example.B. ponds or outbuildings) and away from the foundations, which could require a longer and additional access chambers instead of walking in a straight line. The approved H document contains guidelines for the additional measures needed when exits are to be close to the foundations. Sites of rainwater pipes, sanitary pipes and outdoor gutters can indicate where their underground flows are likely to take place.
A larger roof area increases the amount of surface water. It is best to keep the extra volume on site to avoid an increasing risk of flooding elsewhere. Rainwater can be kept on site by using a soakaway or some other way to get it into the soil (called infiltration), or by being stored and used for toilet flushing or garden irrigation (known as rainwater use). The H-approved document gives advice on where soakaways can be connected, their size and construction. Lazy drainage carries the water consumed from the toilet, sinks, sinks, bathrooms, showers, bidets, dishwasher and washing machine. Surface piping is called sanitary piping; underground pipes are called rotten effluents and rotten sewers. Pipes should be designed for water flow to minimize the risk of constipation and allow for air movement. Tips on pipe size can be found in Document H. Surface water drainage carries rainwater (and melted snow and ice) from hard surfaces. the surface system of gutters and rainwater pipes is called roof drainage; underground pipes are called surface water channels and surface water channels. Our fee covers the cost of: – – – Manage your declaration — – on-site inspection, if necessary — technical assistance – connection with the building control or your licensed inspector — – issuance of your consent or agreement If you expand your property, you must ensure that there are water pipes, public sewers or sewers on your land.
