    Septic Tanks Maintenance: How to Prepare Your Septic Tank for Autumn and Winter

    27th September 2023

    Around the end of September, we all start to feel the effects of the colder weather easing in, and it is no different for your plumbing systems and septic tank. An ignored septic tank in the winter can soon become a rather messy problem, but it needn’t be with routine inspections and sufficient maintenance.

    Pump Your Septic Tanks

    Pumping is essential septic tank maintenance that helps ensure the longevity and functionality of your septic system, and just before winter begins is the ideal opportunity. Septic tanks work to segregate waste into solids (sludge) in the bottom layer, wastewater in the middle and oils and grease (scum) on the top. They also have a maximum capacity, so if you don’t regularly pump them clear, the layers will build up and congeal, meaning there will not be a wastewater layer to escape through the outlet to a drainage field.

    In the cold winter months, a septic tank has more chance of becoming blocked as water and waste harden and get caught in the pipes, preventing anything from escaping, which can result in odours entering your property. Other causes for septic tanks to become blocked are foreign objects being flushed, such as wet wipes, feminine products and nappies.

    Though pumping isn’t an appealing task, it is an important one that can be carried out efficiently by professionals, who will remove the built-up waste and take it away to an appropriate place of disposal.

    Ensure All Leaks are Sealed

    Leaks can have a variety of negative effects on a septic tank and the entire system, which is why regular inspections should be a priority in your septic tank maintenance. The consequence of the leak will vary depending on whether it is water leaking in, or effluent leaking out, but the results will be detrimental to the efficiency of your system either way.

    If the leak allows excess water to enter the tank, it will become overloaded, risking an overflow situation and the excessive water saturation could result in the failure of the drain field. If the leak is allowing water to escape where it shouldn’t, various issues may evolve, depending on where the leak is, including groundwater contamination, drain field failure, system imbalance, soil erosion and health issues. In winter, a leak is at even greater risk due to frost causing water to freeze and expand, turning your leak into a crack or a hole.

    Including a leak inspection in your annual septic tank maintenance schedule is important and should be completed by a specialist company like Cotswold Drainage. Call 01386 882324 or use this simple booking form to protect your septic tank against winter.

    Insulate Your Septic Tank System

    Insulating your system offers great benefits to your septic tank during the winter months, as it helps prevent a range of possible problems. In the colder weather, the liquid and pipes in the septic tank can freeze, causing blockages, damages and potential cracks. The treatment process relies on bacteria to break down the waste, and low temperatures can harm them, but proper insulation helps to maintain a stable, warmer temperature, allowing the bacteria to flourish.

    Insulating anything will always offer great benefits in the colder months by reducing the risks of damage by the cold temperatures. In septic tank maintenance, insulation will minimise the risk of water and pipes freezing, cracks and holes appearing and a system failure. If your system is damaged due to lack of insulation, or you would like to have insulation installed, we're here to help.

    Service Your Septic Tank Regularly

    Regular servicing is crucial for septic tank maintenance, as it minimises risk to your system's efficiency, functionality and longevity. Over time, sludge can build up and reach the water outlet pipes, overflowing into the drainage field and causing a blockage or contamination. Also, untreated sewage can present health risks and release odious and toxic emissions. Ensuring correct functionality helps prevent exposure to harmful bacteria, viruses and other pathogens. Annual services will also protect your system and extend its lifespan, whilst saving you money on costly septic tank repairs.

    An annual service typically includes an inspection of your whole system, addressing and repairing any issues and, every three to five years, a full pumping.

    Fix Any Pre-existing Issues Immediately

    With regular servicing, you are in a much better position when it comes to preventing problems from occurring later, but if you have any pre-existing issues, it is paramount to have them repaired before winter begins, to prevent any exacerbation. The colder environment winter brings can be detrimental to your septic tank for multiple reasons, and if your system already has any cracks or blockages, these may be worsened through frost or freezing temperatures and could end up causing issues that require emergency septic tank repairs.

    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.

    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.
