Modern wastewater systems, built on real-world experience

At STS, we don’t just install tanks — we build smarter infrastructure. With decades of hands-on experience and our own digital monitoring tools, we deliver wastewater solutions that are practical, compliant, and future-ready. Our work is grounded in trust, transparency, and a clear understanding of what customers really need.

Sustainable systems, backed by experience and data

We combine decades of on-the-ground expertise with smart technology to deliver systems that protect local water sources and meet modern environmental standards.

Our approach is practical, low-impact, and built to last — helping you stay compliant while doing right by the environment.

Smart monitoring that keeps systems running smoothly

Our in-house platform gives you real-time insights into your system’s performance — helping you stay compliant, avoid issues, and reduce environmental risk. It’s a simple, effective way to monitor what matters, without the guesswork.

Matching nutrient credits to the right developments
Our proprietary nutrient credit database helps match available credits from Package Treatment Plant (PTP) installations to new developments in need of nutrient offset. While developers don’t access the database directly, our team uses it to verify availability and suitability — ensuring a compliant, efficient solution that supports planning approvals.
Targeted credit matching
Every nutrient credit is linked to a defined location within the same catchment as your development. This ensures the mitigation effect is geographically relevant – supporting lawful and effective offsetting.
Credible, traceable offsets
Credits are only released once mitigation is in place and verified through testing. We maintain strict delivery timelines to ensure nutrient reductions are active before any new development begins impacting the environment.
