If you’ve ever come across CST Group and wondered what our name means, you’re not alone! While CST might seem like just three simple letters, for us it represents who we are, what we do, and the values that drive our business every single day.
At CST Group, CST proudly stands for Cambridge Septic Tank — a name that reflects both our roots and our expertise.
Our Story
CST Group began right here in Cambridge, New Zealand, in 1996 with a clear purpose: to provide reliable, professional, and honest septic and wastewater services to local homes and businesses.
We’re proud to be a family-owned and operated liquid waste company, delivering high-quality service to the Waikato region for more than 25 years. Founded by Barry Brewer, CST Group has grown steadily over the decades, with his sons now involved in the day-to-day operations.
What started as Cambridge Septic Tank Services has since expanded into a comprehensive range of specialised services, including drain unblocking, bulk water delivery, hydro excavation, and CCTV pipe inspections.
At our core, we’re in business to help. No matter the job, you can count on us to get it done safely, efficiently, and with genuine care.
CST Group was created to fill a need for a company that combined:
- Local knowledge
- Technical expertise
- Genuine care for customers
And that’s exactly how Cambridge Septic Tank Services — CST Group — was born.
