    Septic Tanks: Your questions answered

    22nd April 2022

    Septic Tanks are prone to a gradual build-up of deposits and a slowing down of the natural digesting action of the micro-organisms which normally break them down. Leading to malfunctioning of the septic tank causing, blockages, bad smells, overflowing and consequent boggy conditions in the overflow area around the septic tank.

     Can a septic tank cause the toilet not to flush? 

    A common sign of septic tank problems is a toilet that's slow to flush, overflowing or just won't flush at all, and a plunger can't fix the issue. The tank may be full or there could be a blockage in the pipes, so make sure you get this looked at sooner rather than later to avoid major issues and more costs.

    How often should I empty my septic tank? 

    Every septic tank varies and depends on the size and condition of the tank, some septic tanks require emptying every three to five years, some once every 12 months and some more or less frequently. It all depends on the size, the use and the condition of your tank. However, don't make the mistake of waiting until yours is full before doing so because the more sludge there is in your tank, the less efficiently it will work and the more chance there is of it becoming blocked.

    Should my septic tank smell? 

    A correctly maintained septic tank should never smell! If you notice a horrible drain smell in your house or out near the drainage field, this is a sign that there is a problem with the system, and you should have it checked out by a professional.

    Are you following the new guidelines?

    In 2020, The General Binding Rules changed to state that discharges from septic tanks directly to watercourses are prohibited. Therefore, you may need to update and upgrade the treatment system to comply with current rules.

    Very professional operation. From Ellie gathering initial issues and scheduling and Adrian arriving on the day, cant fault the professionalism and workmanship. Adrian knew what he was doing and the job was much quicker than I thought. A pleasure to deal with.

    Very impressed from start to finish. A well established & efficient company with polite & well trained staff. It's what you always hope for but rarely get these days. Very pleased so far with what's been & I won't hesitate to contact you in the future for more drainage treatment.

    Very responsive and professional. Mark took the time and care to explain everything to me, and gave the system a thorough inspection - the world of treatment plants was completely new to me!

    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.
