    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.

    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.
