Approval Request for Underground Filtering Ponds on HI-5 Route

Project Overview

The Cabildo Insular de El Hierro has submitted a request for official approval to install three underground filtering ponds as part of a major road repair project on the HI-5 route, connecting Los Mocanes and Belgara. These ponds will help manage rainwater runoff from the road, preventing flooding and protecting the local water systems.

Infrastructure Details

  • Collecting water from the road surface via PVC pipes
  • Directing water into three large, two-meter-deep underground wells
  • Wells equipped with sediment retention and continuous monitoring features

This infrastructure aims to improve environmental management and safety during heavy rains, a critical concern for residents and motorists.

Public Participation

Authorities are now allowing the public to review the project details and submit any objections within 30 days.

This transparency allows residents and stakeholders to stay informed about infrastructure developments that directly affect local communities and water management practices.

Context and Importance

The move reflects ongoing efforts to modernize El Hierro’s road and water systems, essential for resilient infrastructure on Spain’s volcanic island.
