Aerated Wastewater Treatment Systems must be serviced every 3 months

NSW Health and Local Councils require an Aerated Wastewater Treatment System (AWTS) to be serviced by an approved agent such as BluenGrey every three months, at the expense of the property owner. BluenGrey provides experienced and qualified technicians to perform servicing and repair of all AWTS no matter the brand. All our vehicles are stocked with a variety of pumps and irrigation parts and can respond quickly to break downs and emergency call outs.

All septic and AWTS systems must be pumped out every 3 – 5 years

Having your tank pumped out every 3 – 5 years is key to maintaining your AWTS or septic tank system. At a regular service, a technician will recommend your tank is pumped out when the sludge reaches a particular level in the tank. Please contact BluenGrey who can arrange the pump out for you.

What happens at a AWTS Service

At each service, BluenGrey’s technicians test your system to ensure it is working as it should The technicians will:
1. Respect your property and follow OH&S guidelines.
2. Check for electrical safety and if control box and alarm is working at the tank.
3. Check aeration, irrigation and sludge (if fitted) pumps are working.
4. Clean aeration and clarification filters
5. Adjust and operate sludge return as required.
6. Measure sludge accumulation in septic chamber to see if pump out is needed.
7. Check inlet and chamber junctions are clear.
8. Test Ph, free chlorine levels and replenish chlorine as required (up to 6 tablets).
9. Report on status of irrigation area.
10. If fitted and accessible clean irrigation filters.
11. Make comments and recommendations for any additional work that may be required.

Your responsibilities as an AWTS owner

  • Never turn off the system
  • Ensuring that the system is inspected quarterly by a qualified service technician
  • Fixing the system when problems are reported
  • Pump out the system when sludge levels are high (usually every 3 – 5 years)

Rod's expertise is exceptional

We would like to thank Rod for all his guidance and patience while we were investigating water and sewerage systems, and asking a myriad of questions. We had never built before and knew nothing about what we needed for water and sewerage, so Rod was a fountain of knowledge. His expertise has been exceptional. Both the water tank and the sewerage system were installed hassle-free and passed Council inspection without any issues. We look forward to an ongoing relationship with Rod when he visits to do the necessary checks and balances of our sewerage system.

BluenGrey are a great ‘one stop shop’ service at competitive prices

Having made the decision to move to a semi-rural property at Yass we investigated options for our grey and rain water requirements. We approached BluenGrey who provided a range of options for us to select from. Their personal and professional approach, which included on-site meetings, ultimately led us to choose to proceed with BluenGrey who offered a ‘one stop shop’ service at competitive prices. The installation was trouble free and their follow-on service and advice has been excellent. We are completely satisfied with the BluenGrey services and have no hesitation in recommending them to future customers."

BluenGrey were very helpful in every respect

 From our initial conversations through to final installation BluenGrey were very helpful in every respect, and courteous and obliging with regards to my requirements. Work commenced on time as planned with pictures texted through to us during the installation showing progress. All in all job a well done with zero issues. I would recommend BluenGrey to anyone considering waste disposal units and / or rainwater tanks.

I can't recommend BluenGrey highly enough

BluenGrey are an absolute pleasure to deal with. Their Service Technicians are always professional and reliable, and I like to know that our wastewater system is looked after so we're always meeting our Council's regulations. I feel reassured knowing I can call on them should I have any worries about our system, and especially that they can respond to emergencies.
