Water Resources and Geography of Cape Verde

Cape Verde (Cabo Verde) is a volcanic archipelago of ten islands and several islets in the central Atlantic Ocean, approximately 570 kilometers off the West African coast. Total land area is 4,033 square kilometers. The islands are divided into the Barlavento (windward) group in the north and Sotavento (leeward) group in the south. The terrain varies from the flat, desert island of Sal and Boa Vista to the mountainous Santo Antao and Fogo, where the active Pico do Fogo volcano reaches 2,829 meters.

Cape Verde is classified as semi-arid, with average annual rainfall of only 260 millimeters. Rainfall is highly variable and concentrated in a short wet season from August to October. Many years bring severe drought. The mountainous islands (Santo Antao, Santiago, Fogo) receive more precipitation than the flat eastern islands (Sal, Boa Vista). There are no permanent rivers on any island. Limited groundwater exists in volcanic aquifers on some islands, but many sources are brackish or saline.

Atlantic Ocean seawater around Cape Verde has salinity of approximately 36,000 mg/L with temperatures of 22 to 27 degrees Celsius, suitable for efficient SWRO desalination.

Key Water Treatment Challenges in Cape Verde

Cape Verde depends on seawater desalination for the majority of its potable water. ELECTRA (now AEB) operates desalination plants on the main islands, but aging infrastructure and growing demand from tourism create persistent supply challenges. Desalination provides over 85 percent of drinking water on the flat islands of Sal and Boa Vista, which have virtually no natural freshwater. The mountainous islands have some spring water but insufficient volume to meet demand.

Tourism has become the economic backbone, with over 800,000 annual visitors concentrated on Sal and Boa Vista islands. Large all-inclusive resort developments create massive water demand on islands with zero natural freshwater. Many resort properties operate private desalination to ensure supply reliability independent of the municipal system.

Water cost is among the highest in Africa due to energy-intensive desalination powered primarily by imported diesel fuel. Solar and wind energy integration with desalination is a strategic priority. The agricultural sector on Santiago, Santo Antao, and Fogo requires irrigation water treatment from limited brackish groundwater and fog collection systems.

Water Treatment Solutions for Cape Verde

Seawater Desalination

Seawater reverse osmosis (SWRO) desalination systems are the essential water supply technology for Cape Verde. ForeverPure SWRO units feature maximum energy recovery to reduce diesel/renewable energy consumption, with marine-grade construction for the Atlantic island environment.

Reverse Osmosis Systems

Reverse osmosis systems treat brackish groundwater from volcanic aquifers on Santiago, Santo Antao, and Fogo, extending usable water from natural sources that would otherwise be too saline for consumption.

Water Filtration Systems

Water filtration systems provide pretreatment for desalination plants, treat spring and well water, and polish distribution water. Sediment removal and cartridge filtration protect RO membranes from volcanic sand and particulates.

UV Disinfection

UV sterilization systems disinfect desalinated water in distribution, resort water systems, cistern supplies, and food and beverage production.

Industry Applications in Cape Verde

Tourism: Desalination and water treatment for all-inclusive resorts, hotel properties, and resort developments on Sal, Boa Vista, Santiago, and Sao Vicente.

Municipal Water Supply: Desalination systems for AEB/ELECTRA on all ten islands, community-scale treatment, and distribution infrastructure support.

Agriculture: Brackish water treatment for irrigation on Santiago and Santo Antao, fog water collection treatment, and agricultural processing water.

Fisheries: Process water for fish processing, ice production, and the tuna cannery operations that are significant to Cape Verde's economy.

ForeverPure Systems for Cape Verde

ForeverPure ships containerized desalination systems to Porto Grande (Mindelo) on Sao Vicente and Praia Port on Santiago via ocean freight, with inter-island delivery to all ten inhabited islands. Equipment includes Portuguese-language documentation and is configured for Atlantic island conditions with renewable energy integration capability.

Each system is engineered for the specific island's seawater conditions, available energy sources, and capacity requirements. ForeverPure provides complete engineering support and remote commissioning assistance.
