DOES A SEPTIC TANK NEED TO BE EMPTIED?

It is most important that a septic tank is emptied at least once a year.

Septic Tank Emptying

Annual septic tank emptying is important

As detailed in The Operation of a Septic Tank, solids build up in the base of a setpic tank system. If these solids are not removed each year then they will build up in volume and cause the following to occur:-

  1. An increase in the percentage of solids leaving the tank and entering the soakaway system.
  2. A reduced volume in the main septic tank chamber reducing the capacity for gravity to pull solids to the tank base.

By not annually de-sludging a septic tank you are building up potential problems for the soakaway system in the future. MTM dont offer a tank empty service, please contact a local waste disposal company for costings.
