Water and nutrient reuse

Abstract

Caribbean “Small Island Developing States” (SIDS) with a growing population and water demands has a poor development of sanitation and wastewater treatment. This situation produces high loads of organic matter, nutrients and bacteria to coastal zones, where population are concentrated in main cities and villages, causing a negative impact to tourism, fisheries and health. This situation produces high loads of organic matter, nutrients and bacteria to coastal zones, where population are concentrated in main cities and villages, causing a negative impact to tourism, fisheries and health. Eutrophization problems have been addressed. Wastewater nutrients removal technologies and recycling of nutrients through reuse are identified as the key elements to overcome this situation. This paper presents technicians and decision maker involved in the evaluation; planning, design, operation and management of water and nutrient reuse a clear vision of the main questions to be addressed when reuse of treated domestic wastewater is intended. Public concept in wastewater reuse is emphasized.
