Anyone can apply for the contract, including an owner or builder. More relevant is who is qualified, experienced or insured to create the information package required for the construction agreement. Of course, a builder may have experience with the physical work involved, but it is completely independent to have experience with the design and have appropriate professional liability insurance. Builders in the UK do not have insurance for such work. If it is determined that the existing pipe is in poor condition or that the material is fibrous, you will need to rest the length of the pipe under the structure at your own expense so that a superstructure can be considered. This minimizes the risk of structural failure of the pipe after construction and the risk of inconvenience and service failure for you in the future. If you want to build on a sewer, you need a construction agreement. This is necessary if you plan to construct a building, extension, basement or similar construction work nearby or directly above an existing sewer. The distance to the sewer depends on several factors, including the depth of the sewer, the criticism of the sewer, etc., although it is usually 3 m.

If a construction agreement has been reached, the water company does not have the right to remove or demolish the structure above the sewer.

Common problems with construction agreements that are not professionally designed (DIY): A construction agreement gives the water company peace of mind that the work to be done will not negatively affect the sewer below and also ensures that the water company continues to have sufficient access to the sewer so that it can be repaired and maintained….
