AECCM also recommends addressing sanitation and wastewater evacuation in the neighbourhood. These recommendations do not amount to approved or funded sanitation works.

    Sanitation recommendations and debate over sand replenishment

    AECCM proposes a coordinated response including sanitation, wastewater evacuation, environmental protection and resident participation. These are recommendations, not funded works. Coalición Canaria argues that comprehensive recovery and experimental replenishment with volcanic sand from La Palma could be compatible; the sources consulted do not establish that compatibility as settled.
