    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.

    Having researched companies to install a sewage treatment plant for my house, I chose Cotswold Drainage. I have not been disappointed at any stage of the process. From the outset, communication has been exemplary, every person I met, in person or on the telephone, has been very polite, and took time to listen and answer our questions. The quality of the work done has been, to my untrained eye, of a very high standard. Disruption has been kept to a minimum and the area has been left very tidy, now waiting for grass seed to sprout! I had some further pipe work done separately from the septic tank installation, and again, it was a very straightforward process with minimal disruption. Well done Stuart and all at Cotswold Drainage. Many thanks.

    This company carried out some rather difficult works inside a treatment plant for me. There was a longer delay than I expected for the parts but they kept me informed at all times. They carried out the work exactly as planned and on time as they agreed, to the exact price quoted. It was terrible weather and the two men working on site still got the job done and were positive and hard working all the way through. I am impressed with Cotswold Drainage and will continue to use them in the future. They are friendly, realistic, not the cheapest quote I'd had, but certainly honest and knowledgeable people. I don't mind paying slightly more for that level of service. It was stress free and good value in the long run. So when you look at multiple quotes, I'd say consider them above others due to their knowledge, honesty and workmanship.
