As well as cesspit and septic tank emptying services, we offer installation, servicing, cleaning, maintenance and repairs. Free site visits and surveys are available upon request. The MTS fleet of smaller tankers is housed at our Ashford depot which is dedicated to household services.

Our Cesspit and Septic Tank Emptying Services

We recommend frequent emptying of your septic tank to avoid the unpleasant disruption that can be caused by blockages and overflows. MTS can undertake a service at the same time as cesspit emptying – this allows for a full clean, service, repair and replenish while the tank is being emptied.

Septic tank services include advice on jet washing and repairs to soakaways and drains, which can also be carried out at the same time as your routine empty once works have been agreed.

We can upgrade your existing cesspit or septic tank into a sewage treatment plant which can reduce emptying to just once a year. If you’re considering a new treatment plant, we can offer advice and take you through every step of the process from purchase and installation through to upkeep.

Our speedy, professional cesspit and septic tank emptying services are available at competitive rates.

Top Tips for Maintaining Your Cesspit or Septic Tank

  • You should have the sludge removed from your septic tank on a regular basis – we recommend every six months
  • It is advisable to avoid biological cleaning products as this interferes with the biological decomposition process of the septic tank
  • It is important when you use a cesspit or a septic tank that you only flush body waste and toilet paper down the toilet – sanitary products, wet wipes, food, and fat will cause blockages. 

Frequently asked questions about Cesspits and Septic Tanks


What is a cesspit?

A cesspit is a sealed tank underground that collects sewage and wastewater – this is no processing or treatment of the fluid and material that enters the tank. You can learn more about the difference between a cesspit and septic tank here.

What is a septic tank?

A septic tank is also buried underground; however, it is made up of two chambers, one which holds the solids, the other which holds the liquid.

What's the difference between a cesspit and septic tank?

Both cesspits and septic tanks collect wastewater and sewage from households that have no access to mains drainage. The difference is that cesspits simply collect the effluent in an underground storage tank to be emptied regularly, whereas septic tanks use a simple treatment process which allows the treated wastewater to drain away to a soakaway or stream. Read more about the difference between a septic tank and a cesspit.

How does a cesspit work?

A cesspit is simple in that all sewage and wastewater is collected in one chamber which can then be emptied as necessary. It is generally located underground and is accessed through a manhole cover.

How does a septic tank work?

Septic tanks are more complicated, although like cesspits they are buried underground. A septic tank uses a simple treatment process that is designed to allow wastewater to drain away. The tank consists of two chambers – in one, the solids accumulate at the bottom of the tank where they begin to decompose. The liquid moves into the second chamber where any additional solids are suspended, and wastewater is allowed to exit the tank into a soakaway.

How often should a cesspit be emptied?

Cesspits require emptying on a regular basis. Of course, the time between emptying depends entirely on the size of the property and how many people are using the cesspit. Some tanks may need to be emptied monthly, some may only require once annually – and the real number could be anything in between.
