The project was conducted at the Maintenance Department of Super Bock Group (Former UNICER Bebidas), in the centre of Leça do Balio, and covers an overall improvement over the Wastewater Treatment Plant (WWTP) by implementing preventive maintenance in SAP-PM, cutting energy costs in equipment’s and by implementing key performance indicator’s (KPIs) in maintenance supervision. The main objective of the project involved the implementation of preventive maintenance in all assets of the WWTP with support of the software Systems, Applications and Products in Data Processing (SAP) to have a more rigorous level on all maintenance activities, to cut the cost of electrical energy of assets by studying the energy schedule tariffs, creating some maintenance KPIs to know how the maintenance plan is doing and to check other situations and a general monitoring of the WWTP. In the beginning, a background work is made to the topics that will be addressed in development. Then, all the steps for the decisions made and the development of each idea are explained. At the end, the results obtained show that the implementation of the preventive maintenance plan results to about 1100 assets, that the key performance indicators for maintenance supervision are an effective method for supervision and that the project of reducing electricity costs by studying energy tariffs can result in savings up to 20% of electricity costs.
