Recently, an agreement was made public between Rosa Dávila, the president of the Cabildo of Tenerife, and Hugo Morán, the Secretary of State for the Environment. This accord will facilitate an increase in the planned investment by €233 million to finalise the comprehensive wastewater sanitation and purification system for the Island. With this amendment to the contract with the public enterprise Acuaes, the total funding allocated for these processes will approach a figure nearly reaching €400 million. It is widely recognised that this issue is, undoubtedly, one of the most pressing concerns on the Island that demands immediate attention.
