This is another in a series of educational articles on water/wastewater! This document is intended to cover Wastewater Management for Sustainable Future. This generic presentation utilizes my extended number of years of experience

working with Wastewater Management - Sustainable Future.

Presentation Details:OverviewApplications and UsesConclusion

Overview

Water resources are under pressure from the continuing population growth and urbanization, especially in growing nations. Urban populations may nearly double from current approximate 3 billion to about 6 billion by 2060, with numbers of people dwelling in slums may be growing even faster. Many of those cities do not have adequate wastewater management and handling facilities.

This introduces a worldwide menace to human health and welfare, as well as to ecosystems. At least 1.5 million children under six years-old seem to expire almost every year from water related disease and maybe at least half of the world’s hospital beds may be filled with people suffering from water related diseases.

World’s water resources will not change and growing future needs for water cannot be met unless wastewater management is revolutionized. The production and treatment cycle can be handled through better investment and management, major environmental, societal, and economic dividends can be accomplished.

Applications & Uses

Major causes of the world global water quality crisis

Wastewater production is turning out and inadequate infrastructure and management systems for the increasing volume of wastewater produced are at the essence of the

76 Water Today - The Magazine l December 2016

wastewater crisis. Globally, >1.5 million tons of sewage, industrial and agricultural waste is discharged into the world’s waterways, and this is in addition to the unregulated or illegal discharge of contaminated wastewater.

This wastewater contaminates freshwater and coastal ecosystems, threatening food security, access to safe drinking and bathing water and being a major health and environmental management challenge.

Greater than 60 percent of the fresh water we use may be for food production, and much of that water runs back into waterways, along with nutrients and contaminants that are joined downstream by human and industrial wasteland.

Perhaps as much as 80 per cent of wastewater flows untreated into the thickly populated coastal zones. This contributes to the growth of marine dead zones, which already cover an area of approximately 200,000 square kilometers (Km2), perhaps the same area as all the world’s coral reefs.

There may be further losses in biodiversity and ecosystem resilience, undermining prosperity and efforts towards a more sustainable future.

Improved Sanitation and Wastewater Management

Fresh water and coastal ecosystems across the earth, upon which humanity has depended for the younger population, are increasingly threatened and almost 800 million people still may not have access to safe water and perhaps 2 billion, about half the population of the developing world may not have access to decent sanitation.

Presently, much of the wastewater infrastructure in a lot of the fastest growing cities is lacking, under-dimensioned or outdated. It is overwhelming, not planned to accommodate local conditions, unsatisfactory maintained and entirely unable to maintain pace with rising urban populations.

Without better infrastructure and management, many people will continue to die each year from lack of access to clean water.

The financial, environmental and social costs associated with water quality and availability arelikely to increase enormously as

populations continue to grow, unless wastewater management receives essential attention.

A comprehensive and sustained wastewater management in combination with sanitation and hygiene is basic to improved human health, food security, economic development, jobs and poverty reduction.

For perhaps 1 billion people living in areas of water scarcity, expected to increase to >2 billion by 2030, there is no option but to consider wastewater as part of the solution.

Without better infrastructure and management, many people will continue to die each year from lack of access to clean water.

Priority Actions Regarding Water Sanitation

Solutions to the problem of wastewater management need to encorporate a range of existing and new policy approaches and funding mechanisms for a careful and comprehensive, integrated water and wastewater planning and management at national and municipal levels.

This should start from better water quality legislation and voluntary agreements, to market-based instruments and partnership-based financial and management models, bringing together the public and private sectors, not forgetting the vital role of education. Education prerequisite’s a central role in wastewater management and in reducing overall volumes and harmful content of wastewater produced, so that solutions are sustainable.

There are few, if any, areas where investments in integrated planning can have sustainability to provide greater returns across multiple sectors than the development of water infrastructure and the promotion of improved wastewater management, along the whole water supply (including coastal waters), agricultural production and disposal chain.

Prudent and immediate targeted actions should take multiple forms, including the reduction of the volume and extent of water pollution, capture, treatment, reuse and recycling of polluted water, and development of new and innovative technologies and management practices.

Innovation is compulsory at both ends of the pipe to reduce the volume and contamination of wastewater produced, how to

Water Today - The Magazine l December 2016 77

treat or even reuse the waste, and how to do it in an affordable sustainable way.

The Role of Political and Public Sectors

In terms of public spending on health issues, investing in improved wastewater management and the supply of safe water provides particularly high returns.

Wastewater management should be planned with a combination of innovative approaches that engage the public and private sector at local, national and international scales for future scenarios, not for current situations.

Wastewater management should be an indispensable part of the urban and rural development and planning.

Countries should take on a multi-sectoral approach to wastewater management as a matter of seriousness, incorporating principles of ecosystem-based wise management from the watersheds down into the ocean, and connecting sectors that will reap immediate benefits from better wastewater management.

Conclusion:

Implement these considerations identified above for many of those cities that do not have adequate wastewater management and treatment systems to meet their demands of continuing population growth. And then hopefully you are ready to examine now, your use of Wastewater Management - Sustainable Future. However, beforehand or in the process, feel free to reach out to me with your Wastewater Management; Sustainable Future or any other Wastewater questions.
