WaterMill packaged-solution approach
Not a generic box: a treatment system designed to operate in the field.
The value of a packaged system is not only its compact footprint. It comes from the right process, accessible equipment and a clear operating layout.
Biological treatment
The biological scenario is configured around actual wastewater characteristics.
Settlement and separation
Treated water and biological sludge are separated under controlled conditions.
Discharge or polishing
Effluent is assessed against the target and supported with additional stages when needed.
WaterMill in the field
A packaged system is designed around operating realities, from installation to service.
From manufacturing to field installation and service access, each stage shows that compact layout, safe access and maintenance planning are integral parts of the design.

Reference screen-channel dimensions: B 40 cm, L 100 cm, H 70 cm.
Where a suitable existing septic tank is available, its volume can be assessed for presettling and equalization requirements.
To keep the packaged unit clear of the ground, the reinforced-concrete base should extend 50 cm beyond unit B and 100 cm beyond unit L, with an indicative thickness of approximately 40 cm.
A treated-water storage chamber can be added after transport limits and site layout are reviewed.
Technical note: Dimensions in the table are for preliminary assessment. Final dimensions are determined by the WaterMill engineering team after wastewater characterization, peak flow, transport conditions, site elevations, ground data and project-specific concrete requirements are verified.
Selecting the right system
Capacity alone is not enough to select the right system.
Two facilities with the same daily flow may have very different wastewater behavior. Before preparing a proposal, WaterMill evaluates flow, pollutant load, effluent target, site conditions and the operating pattern together.
Site footprint
Layout, service access and installation method are evaluated together.
Wastewater profile
Pollutant load and variation matter as much as daily flow.
Operating scenario
Automation, maintenance access and operator needs are considered from the start.
Technical selection matrix
The right model is not selected from a capacity row alone.
The table below explains how technical inputs become design decisions during the WaterMill proposal process.
| Project input | Design output |
|---|---|
| Daily and peak flow | Hydraulic capacity and equalization requirement |
| Pollutant load and variation | Biological-process configuration |
| Discharge or reuse target | Required effluent scenario and additional stages |
| Footprint and service access | Layout plan and maintenance approach |
| Automation and operation expectations | Control scenario and equipment options |

Engineering and life cycle
We deliver a sustainable system, not just equipment.
Equipment and materials are selected for project conditions from internationally established manufacturers and verifiable technical standards; manufacturing and factory acceptance checks are documented.
Regulation-aware engineering
For wastewater projects within scope, engineering documentation is developed with the applicable Turkish Ministry Circular No. 2018/14 and current technical criteria in view.
From small to large scale
Capacity is engineered around analysis, flow, load and site conditions, from small facilities to municipal, industrial-zone and large industrial plants.
Turnkey delivery
Process design, equipment selection, manufacturing, automation, installation, commissioning and operator guidance can be delivered under one project scope.
Continuous technical support
Warranty, preventive maintenance, repair, spare parts, consumables planning and process-performance support are addressed throughout the system life cycle.
A wastewater system works well in the field when the process is right from the beginning. WaterMill treats packaged systems as more than a collection of equipment: they should be operable from commissioning day, serviceable over time and adaptable when the requirement evolves.
We evaluate flow variation, pollutant load, footprint and effluent target together, then design a system that is capable without becoming unnecessarily complex. The goal is not to select a generic product from a catalog. It is to configure the right system for the field.

FAQ
How is capacity determined?
Capacity is determined using flow, pollutant load and discharge targets.
Can automation be added?
Yes. The control and monitoring scope is configured around the facility's operating needs.
Can every facility use the same packaged system?
No. Wastewater profile and site conditions may differ even at similar flows. The process and equipment layout are assessed for each project.
Can treated water be reused?
When reuse is a target, the necessary polishing and disinfection stages are evaluated separately within the project scope.
