Costa Rica: Water
Total Water Volume: 113 billion cubic meters (bcm) – or about 29.85 trillion gallons.
- Total water volume includes surface water (75.7 bcm or 20.0 trillion gallons) and ground water (37.3 bcm or 9.85 trillion gallons).
- Annual Precipitation (average baseline): 2,926 mm (115.2 inches).
- Potable or rechargeable water supply per person (current): 22,603 m3 (5.97 million gallons).
Almost the entire population of Costa Rica (98% according to United Nations-Costa Rica) has access to potable water. But effective treatment of this water has historically been problematic leading to Costa Rican President Carlos Alvarado, in 2020, signing a law guaranteeing access to safe drinking water as a constitutional right.
