Establishment of Drinking Water Treatment Facility

Envora Global implements drinking water treatment facilities for industrial and corporate-scale applications with a turnkey approach that encompasses raw water analysis, process engineering, mechanical-electrical design, PLC/SCADA-based automation, field assembly, and commissioning stages. Projects focus on capacity planning, regulatory compliance, optimization of energy and chemical consumption, process safety, and continuous operation. After commissioning, technical support is provided throughout the facility’s lifecycle with maintenance, spare parts, remote monitoring, and process optimization services.

Industrial facilities, organized industrial zones, campuses, and municipalities require a reliable and standards-compliant drinking water supply, which is a critical infrastructure component. Fluctuations in raw water quality, increasing consumption values, and regulatory pressures have made drinking water treatment facilities an integral part of operational continuity. Envora Global is an engineering firm that establishes turnkey drinking water treatment facilities for industrial and corporate-scale projects, ranging from raw water analysis to process design, mechanical-electrical project development to automation and commissioning. Our goal is to build facilities that are optimized for operating costs, have high process safety, are durable, and fully comply with regulations.

The establishment of a drinking water treatment facility, especially when considered on an industrial scale, entails a multidisciplinary study encompassing process engineering, mechanical design, electrical-automation integration, and field applications. Envora Global evaluates projects based on process safety, operational continuity, and total cost of ownership (TCO) criteria.

The project begins with the analysis of the raw water source (groundwater, surface water, dam, lake, well, etc.) and the consumption profile. Daily average flow, peak flow, 24-hour consumption curves, capacity increase scenarios for future years, and relevant drinking water standards are considered. Physical, chemical, and microbiological parameters associated with raw water are clarified through laboratory analyses and field measurements. These data form the fundamental inputs for the process design.

Next, a process flow diagram is created suitable for the characteristics of the raw water. Depending on the needs, process steps such as pre-treatment (screening, static mixing), coagulation-flocculation, sedimentation/lamella sedimentation, pressure sand filtration, activated carbon filtration, iron-manganese removal, softening, ultrafiltration, or reverse osmosis are configured. Disinfection options, including chlorination, UV, or ozone systems, are evaluated. The goal here is to create a design that balances investment costs with operating costs while also offering process flexibility.

During the mechanical design phase, tank volumes, backwash flows, chemical dosing points, piping lines, and valve configurations are calculated. All components used (pumps, filter vessels, instruments, valves, dosing units) are chosen from certified products suitable for industrial working conditions. For facilities that operate 24/7, redundant pumps, bypass lines, parallel filter configurations, and necessary isolation scenarios for maintenance and repair are taken into account.

On the electrical and automation side, the facility is designed with options for PLC-based control, SCADA monitoring, data logging, and remote access. Process parameters (flow, level, pressure, pH, conductivity, free chlorine, etc.) are measured online, and the system is controlled automatically based on this data. In case of alarms and failures, notification and reporting infrastructures are designed to provide operators and responsible technical teams with the ability to respond quickly.

During the field application phase, construction infrastructure, mechanical and electrical assembly works are carried out in coordination. Envora Global optimizes the commissioning process by aligning the site work schedule with the calendars of other disciplines (construction, architecture, infrastructure, etc.). After completing cold tests, pressure tests, function tests, and performance tests, the facility is gradually put into operation, and compliance with design criteria is verified.

After commissioning, the operator team is provided with detailed training on process operation, chemical preparation and dosing, filter backwash procedures, failure scenarios, and periodic maintenance plans. Envora Global remains alongside its clients throughout the facility’s lifecycle by offering services such as maintenance contracts, remote monitoring support, process optimization efforts, and capacity increase.
