Constructed Wetlands as a Greywater Management Alternative in the Tourism Industry

Abstract

The exponential increase in tourism escalates greywater production from laundry, gardening, bathing, and sewage treatment, leading to water scarcity. Simple physical and biological processes can purify greywater for reuse, leading to water conservation. Constructed wetlands offer new approaches to dealing with greywater, especially in polluted tourist areas, through plant, soil and microbial activity filtration processes. These systems are feasible for tropical regions with limited water resources. This chapter examines the suitability of constructed wetlands for greywater treatment, highlighting techniques, performance evaluations and environmental benefits. By integrating these systems, tourism facilities can reduce their ecological footprints with significant savings on water consumption. Constructed wetlands aid in improving greywater management and promoting sustainable water use because they have numerous advantages, such as low maintenance costs and adaptability, which are crucial in ecological preservation amidst rising tourism numbers.
