A Build Over agreement gives the water company the assurance that the work to be done will not negatively impact the underlying sewers and also ensures that the water company retains sufficient access to the sewers so that it can be repaired and maintained. If you plan to build near or above a public sewer, you should contact the water company before the work done to identify the needs. Please send an email containing all the basic information relevant to an offer, including proposal plans, remediation plans, measures, photos, planning conditions or anything relevant to the proposed construction agreement. Construction agreements are a complex field, both technically and legally, and those who are not professional developers should consider professional advice. A professional civil engineering consultant with particular experience in construction contracts, sewers and foundations should be hired. The cost of damage to sewers or foundations without permits or agreements can be prohibitive. Common problems with construction agreements that are not professional (DIY): if you want to build via a sewer, you need a build-over agreement. This is necessary if you plan to build a building, extension, support or similar work near or directly over an existing sewer. The distance from the sewage drainage channel depends on several factors, including the depth of the sewers, the criticism of the sewers, etc., although it is usually 3 m. The control of buildings therefore requires both details of the proposal and a copy of the overconstruction agreement made available by the sanitation authority.
If no build-over contract has been concluded, the seller should have a CCTV investigation carried out on the sewers and transmit the film equipment to the water company. If the water company is satisfied that the sewage disposal channel is in good condition, it will issue a comfort letter confirming that the sewage disposal channel is in satisfactory condition. The comfort letter usually convinces the buyer and their lender that the water company will not take any action to demolish the offensive structure above the public sewers. Thirdly, the risk of damage to the building due to sewer failure is not excessive, since it depends on the individual situation, but for a request for overbauche of a public sewer, you probably need the following: first, that the building, extension or work that involves support – are sometimes problems, when owners attempt to sell their property, partially or entirely built over a public sewer. Winter gardens and extensions are the usual culprits. If no construction contract was concluded during the execution of the work, the water company has the legal right to enter the land to access the sewers, even if it means that the structure above the sewers will be demolished. . . .
