The wastewater system located on Yellow Tail Street, and Grouper impasse at Sandy Ground has recurring overflow problems.In addition, the existing network and discharge stations are outdated and generate significant parasitic water inflows. The EEASM plans to take over the network of the targeted area, as well as the abolition of one of the two lift posts (PR) and the renewal of the second PR The work will take place in two phases: 1. the first phase will respond to the urgency caused by recurring overflows of the wastewater network, i.e. the renewal of approximately 65 ml of the gravitary network rue Yellow Tail for an amount of EUR 115000 2. The second phase will optimise the operation of the network in the area by removing 1 PR by reviving the second PR and 44 ml of gravity network deadlock Grouper for an amount of EUR 295000 These amounts are supplemented by the ancillary missions: Study, project management, external control and SPS
