One of the key principles in maintaining and enhancing the performance of construction projects is continuous monitoring, condition analysis, and timely reconstruction. Due to damages caused by poor initial execution in the mentioned project, Pars Nasb Afarin Company, relying on its technical expertise and specialized team, undertook the complete reconstruction of structures, repair of the drinking water tank, and execution of road concreting in accordance with technical specifications, successfully completing the project. Additionally, the safe transfer of treated wastewater and excess sludge from the treatment plant output was carried out in full compliance with environmental principles.
