The Austin Bluewater Precast Concrete Sewage Treatment System – Absolute Concrete

The Austin Bluewater Precast Concrete Sewage Treatment System

The Austin Bluewater 2K is a single tank multi-chamber system that sees clean recycled water streaming for re-use on planted fields and features.

Using a bio-cyclic process, your waste-water is turned back into water clean enough for safe re-use on your own land.

Great for properties that have limited space or lifestyle blocks close to a natural water-course or stream.

Field installation costs less than a standard primary system, and running costs are lower than an average Auckland Wastewater Rates Bill, even with bi-annual maintenance costs included!

Description

Description

The Austin Bluewater system has been designed by the original designer of the Oasis Clearwater and he has taken his original design and made it even better. Housed in a single concrete tank with adequate capacity to treat waste water for up to 10 persons. The Austin Bluewater system incorporates five chambers to effectively process and treat your home wastewater, turning it back into a clear, odourless liquid that can be reused on-site (subject to local authority approval) for applications such as watering trees and other planted out areas.

Accredited Performance

In the OSET NTP Trial 12 The Austin Bluewater AB2K system was tested at 1,000 litres/day (equivalent to servicing a 3-bedroom 5 to 6 person household) over an 8 month (35 week) period followed by a 1 month (4 week) high load effects test involving 5 days at 2,000 litres/day then 1,000 litres/day over the following 3 weeks where the Bluewater system achieved an A+ rating for both BOD5, TSS and Nitrogen along with best in class for faecal coliform levels.

Features

  • The Austin Bluewater 2K is an aerated treatment tank system which uses totally natural biological processes to treat the waste water.  It consists of a set of 5 chambers which perform various treatment processes on the waste stream.
  • The Bluewater 2K uses high quality components, and all internal chambers are solid concrete for durability.
  • The Bluewater 2K is quiet and economical in operation.
  • The Bluewater 2K has a total running cost (Electricity) of around 50 cents per day or $182.00 per year not including service costs which is not bad when you consider that the average fixed wastewater charges in Auckland are $264.00 per year and then you get charged based on metered water usage on top of that.
  • The Bluewater 2K systems are a compact sewage treatment system housed in one concrete tank.  It is intended to treat domestic waste water from single households with adequate capacity to treat waste water for up to 10 people.  They are  simply installed in-ground and then connected to the household plumbing system and to the power to run the air blower, electronic alarm control unit and the irrigation pump.  The system is then ready to irrigate to an area usually approved by local council.

The Austin Bluewater 2K units are producing water to the “ADVANCED SECONDARY” level – Previously only available in the South Island and Lower North Island, we are happy to bring them to the Central North Island all the way North to the cape.

Care and Maintenance

It is important to realise that on-site waste water systems require regular inspection and maintenance to ensure that they function efficiently and effectively and the system must be operating correctly to ensure that the health of your family and the community are protected at all times.

Absolute Concrete can provide you with options for an ongoing maintenance program for your peace of mind. This will ensure that your system continues to operate as designed, warranties are protected and the unit will continue to function correctly in the long term.  It is useful however for you to familiarise yourself with the system so that you understand the general operation of the unit but it is likely that council will need a maintenance contract in place with any sewage system as part of your building consent.

Chamber 1 & 2. Wastewater from the home is piped to the primary chamber where anaerobic and other oxidising bacteria break down suspended solids. This chamber also receives activated aerated sludge from the clarifying chamber that stimulates the bacteria and enhances the level of solids digestion.

Chamber 3 & 4 Fluid is decanted from the second chamber through a proprietary effluent filter to eliminate the passage of grease and floating matter. Oxygen is dispersed through this chamber via a fine air diffuser powered by an air blower. The Bluewater is unique in that it has two aeration chambers containing submerged Bioblock media for higher quality output and class-leading lower nitrogen levels.

Chamber 4. Liquid from the aeration chamber flows into the clarifying chamber. Any suspended particles to settle to the bottom where they are drawn back via a venturie system and returned to the primary chamber for further processing.

Chamber 5. The treated wastewater flows to the pumping chamber where it is pumped out in dosed loads to a dispersal field that is often designed to irrigate gardens, shelter belts and other planted areas.

Land application systems vary according to individual situations and are most commonly made up of pressure compensating dripper line but can also be in the form of surface sprinklers, subsurface irrigation, sand filters or other innovative systems.  Your local council will decide this.

Owners/Tenants Responsibilities

  • Absolute Concrete can suggest a maintenance person in your area if required, or you could contact your local council for a full list of licensed service personnel.
