Engineering and technology for sustainable water management
In water and wastewater projects we combine a needs-specific engineering approach with environmentally friendly technologies and a long-term operating mindset. With the HydroBioX and System O)) passive treatment solutions, we aim to turn wastewater into a resource that can be put back to use.
Who We Are
IWA brings the engineering discipline of the water and wastewater field together with a technology-driven capacity for developing solutions and the real needs of the field. We handle projects within a single chain of responsibility: from needs analysis to implementation, and from commissioning to long-term monitoring.
We believe water should not simply be used, but protected and put back to use. At IWA, we handle water and wastewater projects from needs analysis to implementation and from commissioning to monitoring; with passive technologies such as HydroBioX and System O)) that prioritize low energy and maintenance needs, we aim to generate measurable environmental and social benefit.
Our Solutions
In water and wastewater projects we combine a needs-specific engineering approach with environmentally friendly technologies and a long-term operating mindset.
Business Areas
From finding water to treating it, and from production to reaching the consumer, we take engineering responsibility at every link of the chain.
Compact, new-generation passive biological wastewater treatment
We apply the compact HydroBioX solution, developed for homes and residential projects without sewerage infrastructure, end to end: from survey and sizing to installation and commissioning.
Proven passive treatment, adaptable to different scales
We apply the System O)) solution family in Türkiye, engineered for capacities ranging from single homes to communal living areas, tourism facilities and corporate campuses.
Making wastewater part of circular water management
We assess the potential for reusing treated water in irrigation, landscaping, cistern supply or other technical needs, within the framework of regulations, quality criteria and project design.
The right decisions before investment, a system chosen for your project
We determine the system suited to your project by addressing needs analysis, feasibility, technology comparison, capacity calculation, technical specification and the implementation plan together.
Applying the design correctly in the field
Within the approved project scope we plan procurement, installation supervision, inspection and commissioning, ensuring the system reaches its intended operating conditions.
A system is measured not by its installation but by how well it is run
We provide sustainable operating support: performance tracking, periodic inspection, sampling, maintenance planning and, where needed, capacity or process improvement.
A Shared Promise
System O)) and HydroBioX are passive wastewater treatment solutions developed for projects where there is no central sewerage infrastructure or where on-site treatment is required.
Working on the principle of biological treatment, these systems reduce the need for electricity, complex mechanical equipment and continuous chemical use, helping domestic wastewater to be treated in an environmentally sensitive way and put back to use under suitable conditions.
With solutions that can be engineered for needs ranging from single homes to communal living areas, and from tourism facilities to rural settlements, we aim to turn water from a waste stream into a reusable resource.
Products
We represent in Türkiye two treatment systems that operate without electricity, mechanical equipment or chemicals, and we carry out the entire process from survey to commissioning.
Compact, new-generation biological wastewater treatment
HydroBioX is a compact wastewater treatment solution developed for homes and residential projects without sewerage infrastructure. Born out of DBO International's many years of field experience, the system combines biological treatment performance with a smaller installation footprint and a simplified application structure.
Proven wastewater treatment solutions adaptable to different scales
System O)) is a passive, biological family of solutions developed for treating domestic wastewater on site and putting it back to use under suitable conditions. It can be engineered for different capacities, from homes to communal living areas and from tourism facilities to corporate and industrial campuses.
Selection Guide
Both systems are passive and biological; the difference emerges in the scale of your project, the installation area and the design effort required. The table below compares the two solutions against the same criteria.

Request a Project AssessmentOur Working Model
From understanding the need to monitoring the system's long-term performance, the same team carries out every step. Commissioning is not the end of the project, but the beginning of its operating life.
We gather initial information about the project's purpose, existing problems, capacity, site conditions, usage scenario and targeted outcomes.
We examine existing analyses, infrastructure, site conditions and relevant technical requirements. Where necessary, we determine the need for samples, site visits and additional measurement.
We prepare a project proposal that brings together technology selection, process approach, capacity, layout, implementation program and operating requirements.
In line with the approved scope, we plan procurement, installation, inspection and commissioning; and we support the system in reaching its targeted operating conditions.
For sustained performance, we provide operational follow-up, maintenance planning, technical support and, where needed, improvement recommendations.
Sustainability
Sustainable water management is not only about finding new resources; it is about using the existing resource more efficiently, preventing pollution and, under suitable conditions, returning water to the cycle. IWA's solution approach is built on this holistic understanding.
We enable domestic wastewater to be treated safely and on site in settlements without central sewerage infrastructure. Putting treated water back to use under suitable conditions helps reduce pressure on clean water resources.
We aim to turn water from a waste stream to be disposed of into a reusable resource. A permanent filter medium and a simple operating structure limit the need for consumables and equipment replacement.
By removing the need for electricity during treatment, passive treatment aims to reduce the operation's energy-related indirect carbon impact. The contribution is indirect because it depends on the alternative being replaced and on project conditions.
When suitable advanced treatment and disinfection are provided, treated water can be used for agricultural irrigation to the extent permitted by regulation. In water-constrained regions this is an indirect contribution that supports continuity of production.
We build sanitation infrastructure that can operate off-grid for villages, rural settlements and communal living areas. This contributes directly to the infrastructure resilience of those settlements.
Preventing untreated domestic wastewater from reaching soil and surface waters reduces pollution pressure on terrestrial ecosystems. As the scale of the effect depends on site conditions and the discharge method, the contribution is defined as indirect.
Our Values
What determines the technology we recommend is not fashion, but a set of criteria. The six principles below are applied the same way in every project.
While meeting today's needs, we safeguard the water resources of future generations. In our technology and design decisions we treat resource efficiency as one of the fundamental criteria.
We base our decisions on field data, water characterization, applicable technical criteria and measurable performance targets.
We clearly share project scope, expectations, responsibilities and technical limits, and build long-term relationships of trust with our stakeholders.
We see water not merely as a technical matter, but as a fundamental element of life and development. We evaluate the impact of every effort on people, the environment and society together.
Every region's water characteristics, climate, infrastructure and operating conditions differ. We develop our solutions not with off-the-shelf templates, but by understanding local needs.
We follow new technologies, research findings and good practices, and bring our accumulated knowledge to our projects and working methods.
Projects
Every water project is as specific as the conditions of its region and the needs of its users. At IWA we build our project approach on technical accuracy, feasibility, resource efficiency and long-term operating performance. We will regularly publish here the completed work for which we have sharing permission.
Share your need; let our team assess the right engineering approach for your project.
