FAQs
-
What is a Septic Tank?
A septic tank (system) is a method of wastewater treatment that utilises only anaerobic bacteria (bacteria not requiring oxygen to live) in the treatment or septic tank. The tank has no aeration and treats the wastewater to about 20% of the amount needed to render it harmless to the environment.
-
What is a Home Sewage Treatment Plant (HSTP)?
A Home Sewage Treatment Plant (HSTP) is similar to a Municipal Sewage Treatment Works, except that it is designed smaller to fit in your own back yard. A HSTP can also be commonly referred to as an OSF, an onsite sewerage facility, aerobic wastewater treatment system (AWTS), aerobic wastewater treatment plant, wastewater treatment system, sewage treatment plant or sewage treatment system.
-
Do I need a Septic Tank or a HSTP?
We will assess your property or existing system, and work out what is best suited at your home based on council requirement, health and safety and budget. We WILL NOT sell you something you do not need and our aim is to work together to achieve a wastewater solution for you and your family.
-
What is an activated sludge system?
An activated sludge system is a form of secondary treatment that is used almost exclusively in Municipal or Commercial Sewage treatment systems because of its complex management problems, necessitating full time operation and management of various processes by positive human and mechanical intervention. It is a process for treating sewage and industrial wastewaters using air and a biological floc composed of bacteria and protozoans.
-
What kind of Warranty do I get with a new HSTP?
Along with a 15 year structural warranty on your HSTP, you will also receive a 2 year electrical component and pump warranty as well as a 12 month servicing warranty. With a strong, sturdy backing from our steadfast, local suppliers as well as a firm guarantee from us that we will cover all warranties fairly and honourably, you can be sure that your investment is in good hands.
-
Do HSTP's need to be serviced?
YES!, All HSTP’s in Australia, as a condition of their State Accreditation Approval, are required to be serviced by a licenced service technician. The state you are in and the type of treatment system you purchase will determine the service cost and frequency.
-
How much does it cost to service a HSTP?
When installing a new system your first 12 months servicing is free. You can expect to pay approximately $80.00 per service thereafter, depending on your location and the type of system you have installed.
