Septic Tank & Sewage Treatment Plant Services

Most domestic and commercial sewage ends up in central treatment plants where the wastewater undergoes a series of treatment processes to reduce the concentration of contaminants. However, some older properties and properties in rural settings are not always connected to the mains sewer, meaning sewage flows into a septic tank or private sewage treatment plant on their property.

At Drain Doctor, we specialise in septic tank cleaning, maintenance, emptying, installation and repairs, as well as other sewage treatment plant and sewage tank services. 

Sewage Treatment Plant & Septic Tank Specialists

Our licensed team of sewage tank experts can design and install the perfect sewage treatment plant or septic system for your needs. As well as ensuring existing septic tanks and treatment plants are safe and comply with UK regulations, we offer professional repairs and can visit your property to take a look at your septic or sewage tank system and suggest the best course of action.

We can help with:

  • Septic Tank Cleaning
  • Sewage Treatment Plant and Septic Tank Installation
  • Sewage and Septic System Repairs
  • Septic Tank Inspections
  • Septic Tank Conversions
  • Sewage Tank & Treatment Plant Inspections

Whether you need a septic tank cleaning, repaired or converted, or you need a new sewage system installed, our team have the experience, skills and equipment to provide quality solutions and maintenance.


Treatment Plant & Septic Tank Installations

Installing a new septic tank or sewage treatment plant is no small task. You will require expert help from a professional with the experience to take practical considerations into account. Our engineers will ensure they install the best size and model of tank or sewage treatment plant in the most suited location, which will be determined based on the ground conditions and the volume of wastewater produced by your household or business.

Our experienced team of highly trained engineers have the knowledge to meet the precise requirements of sewage tank and septic system installations. They can also source and supply a suitable septic tank or sewage plant to make sure it’s right for your property.

If your septic tank or sewage treatment plant is showing signs of deterioration, our engineers will be more than happy to provide septic tank cleaning, maintenance and repairs.


Septic Tank Conversions

If you own a septic tank, it is your responsibility to ensure that you meet the General Binding Rules. This means making sure your system doesn’t pollute the local environment. As licensed septic and sewage tank engineers, we are certified to help customers meet these standards and undertake septic tank conversions to upgrade septic systems. Installing a conversion unit onto your existing tank is less timely than replacing your current drainage system, and with far less excavation involved, the process will cause minimal disruption.

How Do I Know If My Septic Tank Needs Repairing?

Your septic tank or sewage treatment plant might need repairing if you notice any of the following signs:

  • Unpleasant Odours - A foul stench coming from your drains or emanating from the area of your septic tank or sewage plant could be a sign of a serious problem, so it’s worth getting a professional to check and fix any sewage system issues as early as possible.
  • Slow Drains - If all of your drains, including sinks, baths or showers, are draining slowly and you can hear gurgling water sounds, a fault with your septic tank or sewage plant could be the culprit.
  • Sewage Backups - If sewage is backing up into your drains and toilets, this is an alarming and unpleasant problem that could be resolved by repairing your septic tank or sewage system.
  • Pooling Water - If you notice wastewater pooling around the area of your septic tank, there is likely something wrong with your tank or drainage system that is causing it to overflow.

Very reputable company with a world class service 24/7. I highly recommend them.

Paul P

The Drain Doctor operative, Dan Hayler was extremely good. He took time to explain the situation and did a fantastic job of solving our problem. He is knowledgeable and courteous. I would highly recommend him and this company. Thank you for an excellent service.

Mandy Stuttard

Seriously brilliant company. Anna was so helpful and great on the phone in the booking. Clear job pricing, rather than hourly charges. We have had two other plumbers out to solve this issue without success. They used a camera to find the blockage which was a ceramic piece from previous building work. Can't recommend them enough!

Kathy Pavid

Very pleased with Drain Doctor and operator Dan. Had concerns about partial sewer main blockage and possible sewer pipe misalignment. Camera survey carried out first to identify issues, then complete high pressure clean, then follow up camera survey. First class professional and friendly service - would most certainly use again.

Roy Tubbs

Great service from Anna and her team. Dan carried out the work needed and was polite, friendly and explained what needed to be done.

Tracey Ridgers

Dan turned up within an hour even though it wasn't an emergency. He was professional and very helpful and even identified a hidden chamber that was also blocked. Great quality for a very reasonable price.

Nick Armitage

Called this morning for plumbing emergency. Attended within half an hour and problem fixed. Would highly recommend.

Katie Crawford

Can't recommend Graham Forbes and Drain Doctor enough! 3 hours graft and skilled use of some pretty scary high pressure equipment, camera tech, to break a fiendishly located fat and soap berg in the corner of our kitchen pipe work.

Andy & Katy Travers

Really quick service, called on a Sunday morning, with us within an hour with the job done quickly. I hope not to need my drains sorted again, but if I do, I'll be calling Scott!
