Sewage Treatment Plant


Mains water supplied to households is used for many purposes, other than drinking and food preparation, notably bathing and showering, toilet flushing and the washing of utensils, dishes and clothes. Except where main drainage is not installed, the used water gravitates to the local sewer and becomes ‘sewage’. Domestic wastewater will contain both solid and dissolved pollutants including faucal matter, paper, urine, sanitary items, food residues and a variety of other contaminants. The sewer network will usually also receive wastewaters from office and commercial properties and from industrial premises. Rainwater from roofs and roads may also drain into the sewer network.

Advantages of a Sewage Treatment Plant

  • Reliable and unlikely to encounter problems with only regular maintenance.
  • Can be installed even on challenging or compact sites.
  • Cost-effective over time, with only installation, power and maintenance to pay for.

Disadvantages of a Sewage Treatment Plant

  • The plant needs a constant supply of electricity to run.
  • Will require professional maintenance annually, and in the unlikely event of problems.
  • Design and installation of the system needs to be undertaken professionally.
