    I’m not sure the blockage is on my property. How can I find out?

    20th May 2022

    Have you noticed a blockage or bad smell coming from a drain around your property boundary, and need to know if you're responsible for its maintenance? In general, you are responsible for drains inside your property's bounds, whereas the sewerage company is responsible for lateral drains and sewers that are normally outside of property boundaries. Although most sewers are now publicly owned, there are still some that are privately held or unadopted. If one of these serves your property, you may be liable for its upkeep.

    What’s the difference between a drain and a sewer?

    A drain is a tube that empties water and garbage from a building and other buildings that are connected to it, such as a garage. 

    A lateral drain is a section of pipe that transports wastewater from your property to a sewer. It's frequently found outside your property line, often beneath a public sidewalk or road. If you share a sewer with your neighbour, a lateral drain may flow beneath your property. 

    A sewer gathers water and garbage from several buildings' drains. Many sewers are publicly owned and maintained by your local water provider. There are, nevertheless, some privately owned sewers. Some households are linked to a cesspool, septic tank, or treatment plant instead of a sewer. You will not have to pay sewage rates to a sewerage company if you are not linked to a sewer.

    How can I find out whether it's my responsibility?

    Check your property documents or contact your local government for a more illustrated picture of what pipes are inside your household's boundaries. Check a neighbouring manhole to see if it is full, if it is there is a very high chance it is the responsibility of the local water authority. Just give them a call and they will sort out the issue free of charge.

    Cotswold Drainage Ltd came out on a Saturday and spent a long time trying to clear a stubborn drain blockage. They then returned early the following week and managed to fix what could have turned into a huge, stressful job — especially impressive as two other companies had been unable to resolve it. The 6-month guarantee is a great reassurance, and the team were friendly, accommodating and genuinely made me feel like nothing was too much trouble. They will absolutely be my go-to company from now on. Highly recommended.

    They provided me with a prompt and efficient service when a drain at the back of my house was blocked. The two people I spoke with on the phone and in person were reassuring and helpful. Would recommend.

    Reliable, professional and trustworthy. Adrian resolved the issue of a blocked drainage system, identifying the problem and taking the appropriate action to resolve it, leaving the drain free running and all blockages removed.

    We recently had some work done to our pump chamber which was in need of some significant upgrade. Cotswold Drainage did a great job. Their engineers were professional, knowledgeable and kept us updated on progress. The office staff were great too. Very responsive to sending out the quote and planning the work. Overall workmanship and price was spot on. Will be using them again for the annual service. Well done and thank you.

We recommend Cotswold Drainage to anyone needing reliable, professional support with their sewage treatment plant.
