Sant Bartomeu Del Grau City Council Directly Manages The Municipality'S Drinking Water Supply Service. The Current Technical Hydraulic Performance (Rth) Of The Network Is 82%, A Value That Is Considered Adequate. However, One Of The Priority Objectives In The Short And Medium Term Is The Reduction Of Water Losses In The Network, Especially Taking Into Account That The Municipality Depends On A Single Supply Point, The Vilaseca Wells, Which Makes It Necessary To Optimize The Management Of The Resource As Much As Possible. In This Context, It Is Necessary To Strengthen And Renew The Sections Of The Network That Present A Poor State Or A Repeated History Of Breakdowns, With The Aim Of Improving The Reliability Of The Service, Reducing Losses And Guaranteeing The Continuity Of Supply. Currently, There Are Still Several Sections Of The Supply Network Made Up Of Fiber Cement Pipes, An Obsolete Material That Does Not Meet Current Standards, Which Are Expected To Be Replaced By New Pipes That Comply With Current Regulations. Specifically, The Project Contemplates The Renewal Of Three Sections Of The Network. The Object Of This Contract Is The Contracting, Promoted By The Sant Bartomeu Del Grau City Council, Of The Execution Of The Works Included In The Executive Project To Renew The Drinking Water Supply Network Of The Municipality, With The Aim Of Improving The Efficiency, Safety And Sustainability Of The Service, In Accordance With The Technical And Administrative Prescriptions Established In The Corresponding Specifications.
