Water and sanitation

Water and sanitation are pivotal elements of the Sustainable Development Goals (SDGs), primarily encapsulated in SDG 6 (Clean Water and Sanitation). This goal seeks to ensure the availability and sustainable management of water and sanitation for all by 2030. This objective directly addresses the current global water crisis, where nearly 2.2 billion people live without access to safe water, and about 4.2 billion lack access to adequate sanitation.

By focusing on improving water quality, increasing water-use efficiency, implementing integrated water resources management at all levels, and protecting and restoring water-related ecosystems, SDG 6 addresses not only direct human needs but also the broader ecological health of the planet. Furthermore, efforts towards achieving SDG 6 indirectly promote several other SDGs.

For instance, water and sanitation are crucial to achieving SDG 3 (Good Health and Well-being), as clean water and proper sanitation facilities reduce the spread of water-borne diseases and significantly lower child and maternal mortality rates. Likewise, they are foundational to SDG 4 (Quality Education), given that the provision of water and sanitation facilities in schools significantly impacts the attendance and performance of students, particularly for girls.

SDG 2 (Zero Hunger) also intersects with water and sanitation, as sustainable and efficient water management is critical for agriculture, which remains the largest global water consumer. The necessity of water for food production and the potential impact of improved water management on crop yields and livestock health makes SDG 6 integral to achieving zero hunger.

SDG 6 contributes to SDG 1 (No Poverty) and SDG 8 (Decent Work and Economic Growth) as well. Access to clean water and sanitation can enhance economic productivity by reducing time spent gathering water, reducing healthcare costs due to water-related diseases, and even creating jobs in water and sanitation services sectors.

In terms of environmental impact, the sustainable management of water resources is essential for SDG 13 (Climate Action), as water is a key factor in managing climate change due to its role in agriculture and energy production.

This book chapter advances SDG 3 and 6 by exploring the feasibility/design implications for coastal reservoirs based on estimation of runoff, detailed assessment of water demand and estimation of water quality.

This research explores the use of indigenous waste plant materials for an easy and cost-effective approach for the removal of heavy metals from water.
The empirical analysis shows that unregulated water vending makes households without connection to pay higher tariffs for water. The paper among others recommends that tariffs at which vendors should sell water to customers should be set and closely monitored in order to ensure that households without connections have access to water at reasonable tariffs.
This book chapter advances SDG 3 and 6 by describing properties of water and importance of water to biomaterials and biology.
