    How to check if your septic tank needs emptying

    16th March 2022

    A septic tank is designed to collect sewage and wastewater from households that are not connected to the mains sewer. It’s an efficient way to deal with the waste from your household but does require some maintenance.  Septic tanks do need to be emptied at regular intervals, but how often can vary depending on your model. We recommend having your septic tank emptied regularly, but knowing the tell-tale signs of when your septic tank needs emptying might save you in the long run.

    1. Overflowing

    As the septic tank gets full, the most obvious sign that this has happened will be overflowing. You might notice pools of water surrounding where your septic tank is located. This could indicate that solid waste has blocked up the system, which means the water is pushed up to the surface. Also lookout for a healthy lawn, noticeable healthier than the rest of your garden. This could indicate there is a leak and it’s time to get your septic tank looked at.

    2. A bad smell

    When we’re talking about household waste and septic tanks, the smell is never a pleasant one. If you notice a bad smell that can’t be accounted for close to where your septic tank is, then it’s time for someone to come out and have a look.

    3. Slow Drains

    You might notice your drains stop working as well as they used to. This one is much harder to diagnose, as they could be a multitude of reasons as to why your drains are not draining as they used to. If you notice this across your home and after trying traditional drain remedies; then it might be time to empty that all-important septic tank.

    4. Pipe gurgling sounds

    Again, with slow drains, if you hear that dreaded gurgling sound coming from your drains. This doesn’t mean that your septic tanks need emptying, but it may indicate something is wrong. Especially if you can hear it from multiple drains. Then is it probably time to get them checked out.

    It's important to empty your septic tank at regular intervals and have any required maintenance carried out. This can help fix any small problems before they become bigger problems with a big bill.

    The initial visit by Cotswold Drainage went perfectly and my problem methodically diagnosed by Adrian and drains cleared accordingly. Further work needs to be done to permanently rectify the issue at my property, this work being done shortly so will need to do another review when work completed in full.

    Third time I have used this outfit. They turn up when they say they will, do the job and get you the report the next working day. Ask for Dave Streeter.

    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.
