Description

These Clearwater Package Sewage Treatment Systems are a versatile and cost-effective solution. Using trusted aerobic biological processes for the treatment of sewage, a Clearwater treatment system makes for an affordable and environmentally responsible solution. Quick and easy to install, a Clearwater sewage treatment system is fully compliant with the latest regulations and is designed for low-cost and simple maintenance.

 

Choosing the right sewage treatment plant is important, as in the case of a property alteration or extension, Building Control will strongly advise the installation of a plant which is suitable for handling the increased flows and loads of the new development.

 

Key Features of BTA E-Range Sewage Treatment System:

  • Independently Certified to EN 12566 standard and compliant with Building Regulations.
  • Subject to consent and site conditions can discharge directly into a watercourse.
  • No mechanical or electrical components within the main body of the tank - low running and maintenance costs.
  • Low-level visibility in the garden with a lockable child-proof cover.
  • Controlled ventilation - minimises the risk of odour nuisance.
  • Easy to install and maintain with annual desludging & emptying.
  • Affordable running costs
  • Improved effluent quality with higher BOD and TSS removal than older models
  • Isolator and failure light for peace of mind

Options:
 
Gravity or Integral Pumped System (IPS):
 
Gravity is the standard no cost option, however where the inlet to the watercourse or soakaway is higher than the outlet of the treatment plant you will require the optional Integral Pumped System (IPS) as this will pump the waste water uphill and into your discharge point. Depending upon site conditions the IPS system will pump from 1.0m head upto a distance of 200m or a maximum of 6.0m head with a distance of 15m - Please contact us on 0800 0568 350 should you require more information on the IPS and it's capabilities.
