Regardless of how much or how little you know about onsite wastewater treatment plants, we can help to make your decisions easier.

We provide a wastewater solution that is tailored to your needs, not just a product sale

The objective to treat wastewater is much the same across different industries but the challenges can be quite unique and specific to each site. Various factors have to be measured and evaluated to ensure the BluenGrey solution meets your requirements, time frame and budget, including the type of wastewater, variable flow rates, usage patterns and available land.

We understand wastewater and we take the time to understand the needs and situation of your particular business before recommending, designing and delivering an on-site wastewater solution.

BluenGrey Providing Wastewater System Advice in NSW


  • "Super professional and experienced"

    “Rod Wilks and the crew at BluenGrey put in a massive water tank for us after our old concrete tank began to leak. We were caught north of the Qld border the whole time but just a phone call was all that was needed for Rod and the team to take care of everything for us during our absence, including design, liaison with manufacturers, site preparation and integrating the new tank with existing lines. We genuinely recommend this business to anyone who wants a super professional and experienced outfit for everything tanks and septics.”

    – Bernie and Deb Morrison, Kianga.

  • "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.”

    – Emma, Shoalhaven

  • "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.”

    – Col and Anne Eade

  • "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”

    – Melissa and Scott Jobson, Tapitallee

  • "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.”

    – Steven Hawke, Longbeach
