Rainwater Basin
Rainwater Basin
HST provides complete solutions for stormwater retention basins — from mechanical equipment and gate control systems through to full SCADA automation. Our systems ensure reliable overflow management, protecting receiving water bodies and urban infrastructure from pollution and flooding events. Every HST basin solution is engineered as a complete, integrated system.
Flood Protection
Flood Protection
HST delivers end-to-end flood protection solutions covering hydraulic structures, automated gate systems, early-warning sensor networks, and integrated SCADA control. Our systems protect communities, infrastructure, and industrial facilities from the growing threat of extreme rainfall and river flooding — with fail-safe operation designed for the most critical conditions.
SBR Wastewater Treatment Plant
SBR Wastewater Treatment Plant
The Sequencing Batch Reactor (SBR) process is one of the most flexible and efficient biological wastewater treatment technologies. HST provides complete SBR plant solutions — from mechanical equipment and aeration systems to full process automation — delivering reliable effluent quality across a wide range of flow volumes and load conditions.
Flood Pumping Stations
Flood Pumping Stations
HST designs and automates flood pumping stations forming the backbone of urban drainage and flood protection networks. Our solutions cover pump selection, control panel engineering, SCADA integration, and long-term O&M support — ensuring reliable dewatering capacity precisely when and where it is needed most.
Water Treatment
Water Treatment
HST provides intelligent monitoring and control solutions for drinking water treatment plants and distribution networks. From source abstraction through coagulation, filtration, and disinfection to network pressure management, our systems ensure safe, reliable water supply with maximum operational efficiency and full regulatory compliance.
Process Water Treatment
Process Water Treatment
Industrial facilities require precise, reliable process water treatment tailored to specific quality requirements. HST delivers complete automation solutions for process water intake, treatment, recycling, and discharge — including zero-liquid discharge (ZLD) systems — ensuring regulatory compliance and maximum water recovery.
Wastewater Heat Recovery
Wastewater Heat Recovery
Wastewater carries significant thermal energy that is typically wasted. HST's wastewater heat recovery solutions use in-sewer and in-plant heat exchangers combined with intelligent control systems to extract this energy for heating buildings, industrial processes, or district heat networks — dramatically reducing energy costs and carbon emissions.
Transverse Structures / Fish Ladder
Transverse Structures / Fish Ladder
River transverse structures must balance hydraulic control with ecological requirements. HST provides both the mechanical equipment and intelligent control systems for fish passes and bypass channels — ensuring safe fish migration while maintaining precise flow regulation and compliance with all environmental regulations.
Machines &
Systems
For material separation, flow and level regulation, pool cleaning, as well as fittings and equipment for special hydraulic structures. All products engineered and manufactured in Germany to the highest standards.

Seeing the Bigger Picture
At HST, working systematically means ensuring efficiency in the solution and accountability for the whole. When clients invest, they want a compatible, future-proof system for their money — and they want to remain independent of proprietary suppliers so they can respond flexibly to new innovations and requirements. We think the same way at HST.
Always Better
We create our innovations in the context of our clients’ needs and mature new developments to market readiness — delivering significant user benefits. We do not rest on successful products; we see them as a challenge to achieve better results next time. There is a system for this.
Secure & Reliable
We intelligently interconnect systems and machines, making complex processes controllable and reliably reproducible. Processes are optimally designed — technically and economically. Our system technology allows combinations that unite economic efficiency, versatility, and sustainable safety in products, software, and project management.
Open & Flexible
We rely either on in-house open-source innovations or on solutions based on freely available, flexible open standards — ensuring our clients always have the freedom to adapt, upgrade, and integrate new technologies without vendor lock-in or dependency on proprietary ecosystems.
Innovation in Efficiency
We value the connecting and networking capabilities of our employees — they see the big picture and combine what belongs together systematically. This has been proven in our many products and over 8,000 projects developed and successfully implemented since our founding — making HST a globally demanded solution provider.
Employees: Far Ahead
& Deeply Committed
We value the competency of each individual and open discussion at eye level — both among ourselves and with our clients. We have deliberately abandoned rigid departmental structures in favour of interconnected zones that allow us to adapt flexibly to client needs, including across disciplines.
This creates freedom for optimal exchange and ultimately an efficient workflow that serves our clients’ best interests. New things also require courage — and decision-makers who champion the idea. For this reason, HST has established a culture of recognition and competency development that advances every individual further.
This ensures the best conditions for the success of our projects together. Over the years, a spirit of innovation has taken root among HST employees — making the company an internationally sought-after solution provider.
What Makes Our
Team Exceptional
Modern Production —
Made in Germany
HST develops and manufactures all products in Germany in cooperation with qualified early-stage suppliers. Production facilities for machines, systems, and electrical engineering are organised as lean functional units — supported by modern production technologies and highly trained craftsmen.
State-of-the-Art Facility — Ramsbach
At HST’s new production facility in Ramsbach, near headquarters in Meschede, all stainless steel products for the machine and process engineering division are manufactured and assembled to the highest standard. The facility holds a "Major Suitability" certificate per DIN 18800 Class D, and includes a pickling plant for surface treatment of large-area structures.
Flexible, with Short Lead Times
HST’s manufacturing, assembly, and continuous quality assurance processes enable short delivery times and high flexibility — a solid foundation for on-time and cost-reliable construction. In addition to our own products, individual contract manufacturing in sheet metal processing and auxiliary construction is also performed. All design services use Solid Edge with Synchronous Technology.
Flexible Standards — System Technology Principle
By using industrial standards, interfaces, ready-made modules, and process flows, HST manufactures individually on a project-by-project basis at only slightly higher cost than a standard product — but with significantly lower individual production costs. The result: clients receive individually tailored, high-quality products at near-series-production pricing.
Seamlessly Integrated
Performance
What makes HST exceptional? Is it the innovative products with which HST was a market leader for a long time? The successful implementation of more than 8,000 projects over 30 years? Or the considerate service that our clients appreciate so highly?
"The answer is system technology and networks. At the core of our performance circle is system technology, which we take to perfection. Depending on requirements, we implement what our clients need specifically from a single source — whether a product, a project, or a service."
Our service does not end at the sale of a product or the acceptance of a project. We feel personal responsibility and wish to enhance our clients’ long-term success. Operation, inspections, maintenance, and repair are of course part of our service portfolio.
