Moving Toward Sustainability: Sustainable And Effective Practices For Creating Your Water Utility Roadmap
Introduction:
Sustainable water and wastewater services are critical to providing the American public with clean and safe water and helping ensure the environmental, economic, and social sustainability of the communities that utilities serve. Utilities across the country face tremendous challenges, such as aging infrastructure, an aging workforce, increasing mandates, and competing priorities within the communities they serve.
The purpose of this document is to assist utility leaders with implementing proven and effective practices over time to improve their operations and move toward sustainability, at a pace consistent with their needs and the needs of their communities. It provides utility leaders with a cohesive structure to help them address various challenges proactively and with confidence. The practices described in this document reflect the lessons learned and the practical experience utilities have derived as they have improved their operations. A utility can use this document to identify specific opportunities for improvement and draw on the example practices to create an individualized “roadmap” to more sustainable operations.

Water In The Green Economy
Abstract
Water and its management is becoming not just a local but a global priority. The UN Rio+20 Declaration emphasises the need to establish a green economy as the means to achieving sustainable development while protecting and improving the world’s natural resources. Water is increasingly seen as a central plank of the green economy. It is embedded in all aspects of development – food security, health, and poverty reduction – and in sustaining economic growth in agriculture, industry, and energy generation.

Theory and Practice of Tunnel Engineering
Tunnel construction is expensive when compared to the construction of other
engineering structures. Detailed surveys indicate that the cost of a tunnel support
system ranges between 30 and 50 percent of the total project cost, and can sometimes
reach upwards of 70 percent. Currently, theoretical studies and experiences
obtained from large projects indicate that costs can be reduced by increasing the
efficiency of rock load estimation and support design. In other words, the selection
of a support system or systems suitable for rock mass conditions encountered during
construction processes plays an important role in reducing project costs. Methods
based on rock-support interaction introduce rational solutions for economical and
safe tunneling because they provide a good combination of design and construction
processes.

Impacts of Anthropogenic Activities on Watersheds in a Changing Climate
The immediate goal of this Special Issue was the characterization of land uses and occupations (LULC) in watersheds and the assessment of impacts caused by anthropogenic activities. The goal was immediate because the ultimate purpose was to help bring disturbed watersheds to a better condition or a utopian sustainable status. The steps followed to attain this objective included publishing studies on the understanding of factors and variables that control hydrology and water quality changes in response to human activities. Following this first step, the Special Issue selected work that described adaption measures capable of improving the watershed condition (water availability and quality), namely LULC conversions (e.g., monocultures into agro-forestry systems). Concerning the LULC measures, however, efficacy was questioned unless supported by public programs that force consumers to participate in concomitant costs, because conversions may be viewed as an environmental service.
