It would not have been necessary to obtain a building permit from the wastewater butcher if the sewers were private. The condition of a construction contract is defined in the building regulations, part H4. The other possibility is that the seller will provide the buyer with compensation insurance to protect against financial losses resulting from the construction of the property through a public sewer. It is the fastest and cheapest option, but whether or not insurance is available depends on the circumstances of each case. The housing recidivism situation and the lack of building permits appear to be insurance for compensation. However, as commercial real estate lawyers know, insurance is much more expensive when it comes to commercial real estate. The answer is not clear. The costs of studying the history of sewers under the ground must be incurred to meet the situation, or the costs must be borne by obtaining a compensation policy. One way or another, this is an uncomfortable situation that has not contemplated the transfer of the regulation to private channels and will probably only be more frequent, since real estate that would have been private before 2011 is now falling above the public. All water companies have legal rights to access public sewers on private land. These include sewers located under or near a property.

If the construction permit has been granted by a canal, Severn Trent will still attempt to reach the canal without disturbing the terrain. If this is unavoidable, they will repair all the damage done in reason. If a canal has been built without consent, Severn Trent has the right to reach and protect sewers by any means they deem appropriate. In extreme circumstances, this may include the requirement that all buildings involving public sewers be modified or removed at the expense of the homeowner. 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.
