The design of purification plants follows a structured process that complies with current regulations, in particular the new Public Contracts Code (Legislative Decree 36/2023). This involves progressive stages, from the requirements framework to the executive design, ensuring environmental compliance, efficiency and safety.
The first phases (DOCFAP) include a needs analysis, feasibility study and definition of design alternatives. Subsequently, the technical-economic feasibility project (PFTE) establishes the optimal solution, while the executive project details every aspect of construction and installations. As of 2025, digital tools will be mandatory for contracts over EUR 1 million, facilitating more integrated and efficient management.
Essential technical documents include mass balance, flow and process diagrams, hydraulic profile and plant layouts, all of which are essential for system dimensioning and optimisation. The design must also take into account sustainability, reduce environmental impact and improve energy efficiency.
The engineering of sewage treatment plants requires a multidisciplinary approach, where technological innovation, digitisation and regulatory compliance are key elements to ensure effective and sustainable plants.
