Many sanitation facilities are located at the lowest elevation possible and are therefore vulnerable to climate change-related sea level rise, storm surge, and flooding. More severe storm events can overwhelm facilities. Lower stream levels and higher temperatures can affect water quality.
Climate change impacts on sanitation systems could have negative health implications as well as damaging ecosystems.
Relocating facilities to higher elevations, separating storm and wastewater sewers, and improving treatment to produce a higher quality effluent can help mitigate climate risks.
