The corporate approach of WaterMill Treatment Systems.

Brand and legal entity

WaterMill is a brand of GPM ARITMA SİSTEMLERİ TEKNOLOJİ DANIŞMANLIK İNŞAAT TURİZM SANAYİ TİCARET LİMİTED ŞİRKETİ.

We begin by listening to the water

Every facility is different. Even two factories in the same sector may have very different water sources, operating patterns and day-to-day requirements. We begin with analysis, site conditions and the right questions rather than a ready-made product list.

We turn technical detail into a system your team can operate

WaterMill develops solutions for utility water, process water, wastewater and seawater treatment. Our goal is not simply a system that works on commissioning day, but one your team can manage with confidence over time.

Engineering and turnkey delivery at every scale

From small facilities and communities to medium-sized production sites, municipalities, industrial zones and large industrial investments, capacity is determined by analysis, flow, pollutant load, target water quality and site conditions. Process design, project documentation, manufacturing, automation, installation, commissioning and operator guidance can be delivered under a single turnkey scope.

Regulation-aware engineering

For wastewater projects within scope in Türkiye, the Ministry of Environment, Urbanization and Climate Change Circular No. 2018/14 on wastewater treatment and deep-sea discharge facility project approval, together with applicable technical regulations, is considered during engineering. Final approval remains subject to the competent authority's assessment; WaterMill treats calculations and project documentation as an engineering package prepared for that review.

Manufacturing quality and verifiable equipment selection

Pumps, blowers, membranes, valves, instrumentation, automation and other principal equipment are selected for the project from internationally established manufacturers and technical standards. Manufacturing control, factory acceptance, material suitability and maintenance access are evaluated together for dependable operation throughout the system life cycle.

Warranty, maintenance, repair and continuous technical support

Commissioning is not the end of delivery. Technical support covers warranty, preventive maintenance, repair, spare parts and consumables planning, process-performance monitoring and, where required, capacity or automation improvements.

Clear, measured and verifiable communication

We explain technical decisions clearly and publish product, project and reference information after checking the source. Trust comes from good engineering and from presenting the facts as they are.

Manufacturing and factory acceptance

The complete system is reviewed before it leaves the factory.

Mechanical layout, membrane housings, vessels, piping, valve assemblies, instrumentation and automation components are reviewed against the project scope before shipment. This archive selection shows real equipment during manufacturing inspection and factory acceptance.

Milestones from the reference archive

Engineering knowledge built in the field.

WaterMill reference lists show more than a single product category: they describe an engineering journey across different water sources, industries and operating conditions.

350+Reference records in the current lists
2004Beginning of the traceable reference archive
2Clean-water and wastewater expertise tracks

2004

A traceable beginning in clean-water solutions

The early reference archive includes filtration, activated carbon, softening, disinfection and reverse-osmosis systems across different applications.

FiltrationSofteningRO

2007

Mobile treatment moved to a larger scale

A 4 × 150 m³/hour containerized treatment plant developed for Istanbul demonstrated that transportable systems can also serve high-flow field requirements.
