The announcement of the public tender for the contract work to mitigate the risks associated with detrital flows in Ribeira Grande and Ribeira Nova (streams) in the village of São Caetano, Pico Island was published today in the Official Journal. The intervention represents a global investment of nearly half a million Euros and has a completion period of eight months.
The works will improve the hydraulic circuit of that area, dissipating energy and promoting the retention of solid flows from the slopes of Pico Mountain.
The contract work includes the construction of four dams, three in Ribeira Grande and one in Ribeira Nova, which will be associated with retention basins for deposit of debris and overtopping prevention. It aims to minimise the risks for people and property that are associated with the detrital flows occurring in these streams, especially in periods of higher rainfall, avoiding losses such as those in the recent past.
This contract work to be implemented by the Regional Secretariat Energy, Environment and Tourism, through the Regional Directorate for the Environment, is part of a wide range of investments in the maintenance and upgrading of the extensive hydrographic system of the Azores; the latter covers 7,000 kilometres of lines water spread over 700 hydrographic basins.
