Public sewers can sometimes be found within the boundaries of real estate and can pass near or under buildings. If you are planning to expand your property or build a new building, you should check the location of public sewers. NB: If sewers are pumped, construction above or near an agreement will not be permitted and a section 185 “diversion of a public sewer” will be requested. Sometimes problems arise when owners try to sell their property, which is built in part or entirely through a public channel. Conservatories and extensions are the usual criminals. If a Build Over Agreement was not obtained when the work was done, then the water company has the legal right to enter the land to reach the canal, even if that means demolishing the building above the canal. However, if possible, the water company will avoid the damage and look for other ways to enter the sewers, but the risk remains. If a construction agreement has been reached, the water company has no right to remove or demolish the structure above the sewers. In some situations, specific basic agreements must be reached to protect sewers and sewers, as well as the building or extension itself, from the effects of colonization. During the construction of any construction, you must ensure that there are no public sewers in the area of the planned work. The building code requires that development proposals be considered on the basis of the plans of the local water authority and that they be taken into account when a new building or extension is displayed on its map from a canal within 3 metres. It is not possible to submit a building notice for a new building or extension within 3 meters of a canal on the water of the Thames or Anglian water sewer map.

The law requires that a full plan request be made in all cases. If no construction agreement has been reached, the vendor should have a sewer line review and the records forward to the water company. If the water company is satisfied that the sewers are in good condition, they will give a consolation letter confirming that the sewers are in satisfactory condition. The comfort letter generally satisfies the buyer and its mortgage lender that the Water Company will not take any action to demolish the insulting structure over the public sewers. A construction agreement allows the water company to ensure that the work to be carried out will not adversely affect the underlying sewers and ensures that the water company continues to have sufficient access to the canal for repair and maintenance.
