What our customers are saying

  • new sewage treatment plant Dean delivered our tank and he was a mind of information, explaining everything to me in detail and even talking me into placing the tank in a different location, then explaining exactly why. Very helpful and knowledgeable company, highly recommend them. R.Barnes, Cornwall.

    Richard Barnes

    Dean delivered our new sewage treatment plant himself and what a friendly knowledgeable chap he is. He spent a lot of time with me explaining everything i needed to know, in great detail. He even suggested moving the tank to a better location, which i will now do. He has had years of experience in the drainage industry, he’s very helpful and very friendly. i highly recommend speaking to DTE for all your sewage and drainage needs.

  • Service of the highest calibre! We have recently had DTE complete an installation of a Sewerage Treatment Plant at our property and I can’t praise the team more highly! Our installation became urgent and following a conversation with the office we had someone visit site within 2 hours. A plan was agreed and they were able to start the following day, from start to finish the job was very cleanly and efficiently carried out and we are thrilled with the result. I would have no hesitation recommending Dean and the team, they are clearly experts in this field and professional throughout, Well done team DTE!

  • Took the time and care to fix the problem with me in mind. Came out very late in the evening (gone 10pm) to deal with a sewage leak from the above flats into mine. Took his time and was very careful not to cause anything to splash back into my flat from the drain that for some reason is in my flat, so as to not make it worse for me than it already was. Much better than the previous company who didn’t care about that which was horrendous. So very happy that they couldn’t make it and I got who I did.


    A tricky job completed where others failed. We presented a very difficult problem, with a kitchen drain solidly blocked about 4M round several right-angled bends. 3 other drain companies failed to cure the problem. They persisted, and worked very late to complete the job, and had equipment not held by other companies. The quality of the work was excellent, and the team polite and friendly. Recommended.


    Great service and helpful and friendly people would use again.

  • A fast and efficient end to a blocked drain A great service from Phil of DTE who attended the same day I telephoned to clear a blocked drain for an elderly relative. I would definitely recommend this company, and appreciated the helpful advice given.


    Brilliant service Came out on a Sunday for no extra charge. Solved problem and advised on other essential work including remedying shoddy work done by insurers. All completed with great customer service. Both Dean and Phil kept us fully informed about timings and the work to be done and the price was very reasonable.Would definitely use again and strongly recommend them.


    Fast, efficient, polite and amazingly reasonably priced – you could not ask for more. Very hard working guys who took the trouble to explain how our problem had arisen and how they proposed to sort it out, which they did promptly and without fuss. You could not be in better hands.

    Mari Lane
  • Called out 2 weekends in the trott! Both times spent ages with us sorting out the issues! Can’t recommend enough!

    Lorinda Langford

    Brilliant service from a fantastically dedicated engineer Phil was absolutely fantastic. Worked tirelessly and graciously to fix our drainage system. Hugely experienced and highly knowledgeable in his field Cannot recommend him highly enough.


    Good experience…with lots of humour! Phil the engineer was brill…he found the problem quickly and despite having some problems with his own jet system he managed with sheer brute force and determination to clear the drain blockage…and clean up after!! Great service would highly recommend 😉

  • FANTASTIC SERVICE We had an ongoing problem with our drains. DTE came out on an emergency basis for us and sorted the problem. Highly recommend.


    quality, friendly and efficient service from start to finish! Confident that should any problems arise,Dean and his team would be there to help. Thankyou. cannot recommend these guys enough!

  • Outstanding service from start to finish. We had a very urgent drainage problem which Dean and his team sorted within 24 hours. Extremely helpful and we really appreciated the friendly customer service from both Dean and Ben. We would certainly highly recommend DTE. Thank you very much for fixing a stressful situation so quickly.

    Andy Chubb

    Friendly, Professional & Prompt First Class Service Outstanding service from start to finish. We had a very urgent drainage problem which Dean and his team sorted within 24 hours. Extremely helpful and we really appreciated the friendly customer service from both Dean and Ben. We would certainly highly recommend DTE. Thank you very much for fixing a stressful situation so quickly.


    Unparalleled Service We had an ongoing problem with our main waste outlet, which 4 previous companies had failed to satisfactorily diagnose. … A real nice guy and excellent service at a very reasonable rate compared to many of the firms offering only basic unblocking for double and sometimes triple the rates.Definitely recommend! :)))

  • The whole team in Plymouth Drain and Tank Engineering are excellent – with special thanks to Matt for such hard work and courtesy in all that he does. To say they did a superb job would be understatement. There’s was first class engineering in the placement of a NOVO6 treatment plant that has offered faultless service since the day of its first commission. I have no hesitation in recommending DTE and the whole team – theirs is first class service and one I’d certainly endorse should you need a challenging subsurface problem fixed. Well done DTE – a job to be proud of with thanks from a very grateful customer. BZ

    Simon Jaques

    Didn’t think it was possible to get excited about a new drainage and waste treatment plant but we are so pleased with the repair works and installation carried out by DTE. Matt, Ben and Ian were a great team getting the task done without issue. Always polite, courteous and friendly. From our first meeting with Dean, on a bank holiday Monday and before we took ownership of our wonderful new home, he gave us reassurance that the proposed works were not an issue and not as daunting as they first appeared. Communication is key to good customer service and Dean always responded promptly to emails and phone calls. Would have no hesitation to recommend this company. First class company. Sue Burke. Cornwall

    Sue Burke

    Highly professional, would recommend. I’d like to thank the team at DTE for the renewal of my fence.DTE had a tanker reverse accidentally into my fence knocking it down, having arrived home from work I was obviously disappointed. Dean came out and quickly acknowledged responsibly, his company have done a wonderful job in replacing my fence with a new one.A truly professional approach in customer service. I would recommend this company to anyone.

  • great team ��

    Justine Gelpey

    Absolutely gold standard service from DTE. We had an emergency situation, which was complex and messy. Dean, Matt, Jack & Lisa were totally fab. We were kept up-to-date as things unfolded with the job and Dean went out of his way to find the best way to solve our problems, with the minimum of cost and inconvenience. Dean also researched which part of the job could potentially be covered by SW Water, and helped us to get in touch with SW Water to get things going. Alongside their great work, the integrity, honesty, trustworthiness and sheer likeablility of the DTE guys meant that what could have been a really stressful situation for us, was actually not at all stressful. I will definitely recommend them wholeheartedly to anyone who needs this kind of service.

    Emma Hazeldine

    Knowledgeable about all thins septic tank and sewerage treatment… Great company. Very knowledgeable, timely and responsive. They know their stuff and get on with it – and they’re nice guys too.

    Really good service When our septic tank started backing up, we called Drain and Tank Engineering to help. Dean came out to us, investigated it, and explained the problem. DTE fixed the problem by installing a new sewage treatment plant. Its a much better system and we feel better as we are doing our bit for the environment.Would recommend.

  • praise indeed About 3 weeks ago I realised my elderly mum’s outside drain was blocked. I phoned a national company out of the yellow pages and they sent Dean from “Drain and Tank Engineering”. He was unable to clear it but quickly arranged for another person to come . After a lot of hard work, it was cleared of wet wipes but Dean kept me up to date and checked the next day to see all was still well. A wonderful service. Dawn


    Highly Reccomended what can I say Matt, jack and dean are fantastic, very polite helpful and very professional no job is to big or to smallThey make a great team and we would Highly Recommend them to anyone who needs a new treatment plant ! well done lads


    Satisfaction Guaranteed We called as our Septic tank was continuously filling due to the excessive amounts of rain fall and and an inadequate drainage system. Dean assessed the situation provided a solution which was both comprehensive and affordable. Work was completed in a timely efficient manner with the site being left neat and tidy. Would recommend and use again.

  • Experts Its rare to find such knowledge and customer service these days in any trade. Drain and Tank sent an Engineer out straight away to our septic tank. when we had a problem. We had a new treatment plant installed the next week at a fair price. I would recommend to anyone.


    Outstanding Having had problems with septic tank overflowing we called Dean who was very helpful and sorted our problem out with a new soak away. Very professional and would recommend him to friends.
