The accuracy of flow measurement device for electromagnetic type shall be ±0.5 % of the measured flow. The flow measurement device shall have a minimum capacity of 30% higher than the maximum flow of second stage. 

## 3.3.4.21.2 Intermediate Flow Measurement 

A standard open channel measurement (ultrasonic) unit or in-line flow meter (electromagnetic) shall be installed downstream of the primary clarifier tanks for continuous flow monitoring and recording. Regardless of type, easy access to flow meter for installation, dismantling and maintenance shall be secured and unhindered. For this purposes suitable lifting system shall be provided. 

The accuracy of flow measurement device for electromagnetic type shall be ±0.5 % of the measured flow. The flow measurement device shall have a minimum capacity of 30% higher than the maximum flow of second stage. 

## 3.3.4.21.3 Effluent Flow Measurement 

A standard open channel measurement (ultrasonic) unit or in-line flow meter (electromagnetic) shall be installed before outlet structure for continuous flow monitoring and recording. Regardless of type, easy access to flow meter for installation, dismantling and maintenance shall be secured and unhindered. For this purposes suitable lifting system shall be provided. 

The accuracy of flow measurement device for electromagnetic type shall be ±0.5 % of the measured flow. The effluent discharge line to receiving body shall have enough capacity to carry at least the maximum flow of second stage. The flow measurement devices on effluent discharge line shall have a minimum capacity of 30% higher than the capacity of the effluent discharge line. 

## 3.3.4.21.4 Bypass Line Flow Measurements 

A standard open channel measurement (ultrasonic) unit or in-line flow meter (electromagnetic) shall be installed for continuous flow monitoring and recording. Regardless of type, easy access to flow meter for installation, dismantling and maintenance shall be secured and unhindered. For this purposes suitable lifting system shall be provided. 

The accuracy of flow measurement device for electromagnetic type shall be ±0.5 % of the measured flow. All by-pass lines shall have enough capacity to carry at least maximum flow of second stage. The flow measurement devices on all bypass lines within the WWTP shall have a minimum capacity of 30% higher than the capacity of by-pass lines. 

## 3.3.4.22 Treated wastewater for reuse 

Treated effluent shall be used for washing screens, screen presses, grit classifiers, pipe cleaning (e.g. rod eye application), FeCl$_{3}$ preparation and dilution, mechanical thickening and sludge dewatering plant wash water requirements, watering for landscaping, sprinkler system installed on units, cleaning of tanks, indoor and outdoor cleaning purpose and any other process wise water requirements. Treated wastewater shall be taken from outlet of the disinfection UV system coming after the microfiltration unit. However, the Tenderer shall make his own calculations for quality, quantity and pressure requirements and comply with the local and EU regulations to provide the system with all the necessary units and auxiliaries.
