What should I do if my drain is overflowing outside? +
If an external drain or manhole is overflowing, check whether it is a shared drain serving multiple properties. Since October 2011, lateral drains and public sewers became the responsibility of your water company, so contact them first if the blockage is beyond your property boundary. If it is a private drain within your boundary, call a drainage engineer in Bath to clear the blockage.
What is the difference between a drain and a sewer? +
A drain serves a single property and runs from your house to the boundary. A sewer carries waste from multiple properties and is maintained by the water company. Lateral drains — the section connecting your drain to the public sewer — transferred to water company responsibility in October 2011. Understanding this distinction matters because it determines who pays for repairs.
Do slow-draining sinks always mean a blocked drain? +
Not always. A slow-draining sink is often caused by a localised blockage in the waste trap or the pipe immediately beneath the sink — hair, soap scum and grease are common culprits. However, if multiple fixtures are draining slowly or you notice gurgling sounds, the problem is likely further down in the main drain. A drainage engineer in Bath can distinguish between a simple waste pipe blockage and a more serious drain issue.
Can I build over an existing drain on my property? +
Building over or near a public sewer requires a Build Over Agreement from your water company. For private drains, you do not need permission but you must ensure the drain remains accessible for maintenance. Building Regulations require that drains under or near buildings are adequately protected. A CCTV drain survey before and after construction is strongly recommended to prove the drain's condition.
What is the NADC and why does it matter? +
The NADC — National Association of Drainage Contractors — is the leading UK trade body for drainage professionals. NADC members must demonstrate competence, carry appropriate insurance, and adhere to a code of practice. Choosing an NADC-registered drainage engineer in Bath gives you confidence that the work will be carried out to professional standards with proper equipment.
What should I do if sewage is backing up into my home in Bath? +
Stop using all taps, toilets and appliances that discharge into the drains immediately. Open windows for ventilation as sewage gases are hazardous. Do not attempt to clear the blockage yourself if raw sewage is involved — it carries serious health risks including E. coli and other bacteria. Call an emergency drainage engineer in Bath straight away and keep children and pets away from the affected area.
