Short history of activity:
Thanks to the project twinning Phare RO 01-IB/ST-01, the foundations of a unified and coherent system have been laid for data collection on water flow (abstraction, distribution and discharge) from industrial units, agriculture and from specialised units, a system harmonized with the Eurostat standards. In 2004, within the project a pilot survey on water took place for the reference year 2003, being representative for the Mures hydrographical basin.  
Thanks to the project Phare MB 2002 the methodology for data collection and processing was developed as to wastewater collection, treatment and discharge. In 2005 a pilot survey was carried out on national level and since 2006 the statistical survey was included in the ASP in order to regularly obtain data on the quantity and quality of collected and treated wastewater and discharged in the natural receivers.
