Wastewater
24/7 monitoring of SAİS, Marbin and discharge points
Continuously monitor the effluent quality of your wastewater treatment plants, automatically track legal limits and transmit data to the Ministry of Environment, Urbanisation and Climate Change without interruption. Whatever your plant capacity — whether it falls under SAİS at 5,000 m³/day or above, or under Marbin obligations in the Marmara Basin — meet all your legal requirements on a single platform.
Scope
Municipal Wastewater Treatment Plants
SAİS obligation for plants with a capacity of 5,000 m³/day and above
Plants Covered by Marbin
Treatment plants discharging into the Sea of Marmara
OIZ Treatment Plants
Joint treatment and individual discharges of organized industrial zones
Industrial Facility Discharges
Food, textile, chemical, paper and metal processing sectors
Small-Scale Treatment Plants
Below 5,000 m³/day, voluntary monitoring
Monitored Parameters
Under the SAİS Communiqué and the Marbin Protocol, the following parameters must be monitored online 24/7 and transmitted to the Ministry.
| Parameter | Unit | Legal Limit | Description |
|---|---|---|---|
| pH | pH | 6.5 – 8.5 | Acidity/alkalinity balance of the water |
| COD | mg/L | ≤ 120 | Chemical Oxygen Demand — organic pollution load |
| TSS | mg/L | ≤ 30 | Total Suspended Solids — insoluble particles |
| Flow | m³/h | Plant-specific | Volume of discharged water |
| Temperature | °C | ≤ 40 | Oxygen balance of the receiving environment |
| Conductivity | µS/cm | Depends on the discharge point | Amount of dissolved ions |
| Dissolved Oxygen | mg/L | ≥ 4 | Process health indicator |
How It Works
Cabinet Installation
Sensors, a PLC and a local monitoring cabinet are installed at the discharge point. Your existing PLC infrastructure (Siemens, Schneider, ABB, Mitsubishi) is integrated directly.
Data Collection
Sensor data is read via Modbus TCP/RTU, OPC-UA or analog signal. It is processed within seconds in the local cabinet.
Central Processing
Data is transmitted to the cloud over encrypted MQTT and HTTPS channels. Legal limit comparison and trend analysis are performed.
Ministry Notification
Measurement data is transmitted automatically in the Ministry format. The submission time, content and success status are recorded.
Monitoring and Alarms
24/7 access via web panel or mobile app. SMS/email/WhatsApp notification on limit exceedance, calibration delay or data interruption.
Your Entire Plant on a Single Screen
System status, live sensor data and digital signals on one panel. Comfortable operation in day and night conditions with dark and light theme support.
Reporting and Trend Analysis
Audit-ready reports in Ministry format. Hourly, daily, weekly and monthly trend charts for every parameter. A filterable data table with second-level precision. CSV, Excel, PDF export. Comparative analysis.
Notifies Critical Situations Instantly
Alarm Types
Notification Channels
SMS, email, WhatsApp, mobile push. Routing to different recipient groups by severity.

Frequently Asked Questions
Is installing SAİS mandatory? Which plants are covered?
Wastewater treatment plants with a capacity of 5,000 m³/day and above are obliged to install SAİS. Plants discharging into the Sea of Marmara fall under the Marbin protocol.
Is it compatible with my existing PLCs and sensors?
Yes. Common PLC brands such as Siemens, Schneider, ABB and Mitsubishi, and the Modbus TCP/RTU and OPC-UA protocols are supported.
Where is my data stored? Is it secure?
Raw data is stored in the local cabinet (edge) at your facility. Only summary and instantaneous data is transmitted to the cloud. TLS 1.3+ and AES-256 encryption are used.
How long does cabinet installation take?
It is completed within 3-5 business days, depending on the existing infrastructure.
What happens if the Ministry format changes?
Software updates are distributed automatically. The entire system is updated centrally for a new format or communiqué amendment.
Will data be lost if the internet goes down?
No. The local cabinet buffers the data and automatically transmits it to the Ministry once the connection is restored.
