For the Managing Authority (MA) of the Sectoral Operational Programme (SOP) for the Environment under Romania's Ministry of Environment and Sustainable Development (MESD), STELLA assessed the financial and technical soundness of waste and water infrastructure projects to be co-financed by the Cohesion and Structural Funds and in compliance with the EU environmental directives. One of the issues studied was the impact of the definition of agglomeration under the wastewater treatment directive (91/271/CEE). The project strengthened MA's institutional capacity to perform a sound overall programming and monitoring of EU co-financed projects in Romania and to use efficiently and effectively the funds made available. Through on-the-job co-operation, elaboration of methodologies and staff training, this project reinforced the capacity of MA staff to prepare sound project plans, guide municipalities on the preparation of project proposals, appraise and prioritise project proposals, evaluate project applications and tender documents, manage efficiently the process of evaluation, and monitor the implementation of approved projects. STELLA revised waste and water infrastructure projects' documents such as master plans, feasibility studies, EIA and cost-benefit and sensitivity analyses, and corrected and improved the applications. We also reviewed and edited 11 Cohesion and Structural Fund applications for water and waste projects and revised tender documents according to FIDIC's yellow and red books. At the end of our project, DG Regio had approved almost 1 billion euros worth of water projects.
