Septic tanks, Treatment Plants, Cesspits & Chemical Toilet Holding Tanks

Emptying and Servicing

Septic tanks, treatment plants, cesspits and chemical toilet holding tank need to be regularly emptied to prevent any environmental impact. Most of our customers take advantage of our scheduled emptying service and the frequency of this depends on a number of factors:

  • The volume;
  • The type of waste;
  • The type of system;
  • Where the system is situated.

Dependent on the size and access to the system we have a range of vacuum tankers including:

  • 800 gallons to 6,000 gallons
  • All terrain vehicles if tank is situated off track
  • Super-suction tankers for steep gradient emptying

We also carry out the following servicing packages:

  • air blowers and other internal components in treatment plants are serviced annually to prevent them failing;
  • check and clean the pumping chamber to make sure the pump and floats are free from grease and working satisfactorily on a regular basis. If a fault is identified we can replace and repair.

To meet these needs and, based on our extensive knowledge and experience, we will provide you with the best solution.

Since 2019 we have operated our own in-house treatment works and therefore process septic tank waste ourselves.  The customer benefits from this by us responding faster and on a 24-hours basis.

If you haven’t already, you will need to register your septic tank, treatment plant or cesspit with Natural Resources Wales (NRW).   For information and guidance on how to do this visit https://naturalresources.wales

To register, your system must meet certain criteria.  If you are unsure of the set-up of your sewage system or whether you may need to upgrade your system to meet NRW’s requirements, please call us for advice.

We offer a 24-hour emergency service or a scheduled maintenance programme.

Design & Installation

We specialise in all types of installation work.  Because every system is different, we will arrange a time to come out to inspect the current structure, discuss your requirements and provide recommendations and a quotation for the required work.

We may recommend repairing the existing system or, if this isn’t possible, installing a new system.  There are a number of reasons why a system may need repairing or replacing e.g. the current system is damaged or that is doesn’t meet current regulation requirements.
