ENVIRONMENTAL FACILITIES

The marina has a range of fixed and mobile equipment to prevent and mitigate pollution, emissions and spills.

The boatyard hardstanding has a perimeter drainage channel connected to an oil separator. It collects surface wash water and directs it to a wastewater treatment plant installed in 2012 to treat water from boat cleaning. The hardstanding extension completed in 2021 was included in the original plan, with drainage pipes already installed and connected to the treatment plant.

WASTEWATER TREATMENT PLANT

To treat this water, Alcaidesa Servicios installed a CT-MARINE-20 hull-washing water treatment unit that combines physical and chemical processes to remove the pollutants typically present in boatyard wash water, including:

  • Oil removal of non-emulsified oils and hydrocarbons using coalescing separators of the type used in the petrochemical industry. The separated oil is collected automatically in a tank.
  • Coagulation, flocculation and chemical precipitation followed by the sedimentation of heavy metals, ionic surfactants and suspended solids as sludge, using low doses of chemicals specifically formulated for hull-washing water.
  • Final filtration through several layers of activated carbon and natural zeolite to remove remaining dissolved metals, non-ionic surfactants and organic matter.
  • Final wastewater disinfection using an ultraviolet sterilisation unit.
  • Automatic dewatering of wet sludge using drainage bags that minimise the volume of waste sludge and the cost of disposal.

In accordance with the discharge permit, the treated water undergoes quarterly laboratory testing for suspended solids, oils and fats, pH, hydrocarbons, total organic carbon, copper and zinc.

SOLAR PHOTOVOLTAIC INSTALLATION

Between late 2023 and early 2024, a self-consumption solar photovoltaic system was installed on the roof of the new dry-storage building in the boatyard, comprising 357 photovoltaic modules covering the 1,000 m² roof area.

The system’s energy output in its first year is estimated at 242,828.61 kWh. Combined with the existing photovoltaic system on the boatyard buildings, installed in 2018, this will bring estimated annual generation to 327,178.61 kWh, equivalent to the annual consumption of 1,000 homes. One of the main benefits of rooftop solar systems is that electricity is generated close to where it is consumed. The installation will improve the marina’s energy efficiency and reduce its carbon footprint.

The overall environmental benefit is an estimated reduction of 85,065 kg of CO₂ emissions per year, equivalent to the environmental effect of 4,253 trees.
