Wastewater flow measurement campaign and wastewater analysis

Wastewater flow measurement campaign​ (lot 1):

• Review and assessment of the current sewerage system situation​
• Definition of the wastewater measurement campaign for the definition of the wastewater flow production of users, definition of infiltration of water (potable water, seawater or rain/storm water) and for the modelling of the system by EGIS​
• Execution of the flow measurement campaign (39 sewerage pumping stations, 7 manholes, 1 WWTP Inlet) with respect of best practice of health & safety aspects and procedures​
• Meteorological parameters measurement​
• Additional activity: evaluation of mud volume on the primary pond of the WWTP​
• Analysis and interpretation of results regarding the current dysfunctions of the system ​
• Recommendations of actions​

Wastewater analysis​ (lot 2):

• Definition of the sampling campaign (sampling period and frequency & sampling sites)​
• Analysis in situ of the main physical chemical parameters ​
• Samples sent to a French Laboratory for COD, BOD5, Organic SS, Total suspended solids, Total Nitrogen, NO3, NO2, NH4+, Azote Kjeldahl, Phosphorous, pH​
• Analysis and interpretation of results regarding the current dysfunctions of the system ​
• Audit of the existing Laboratory of PPUC​
• Staff training​
• Recommendations of actions​
