OCEAN is an online resources of the Building Codes Assistance Project. Here they provide a case study of the work happening in San Antonio. On March 12, 2009, the San Antonio City Council voted to approve and adopt a new Sustainable Buildings Ordinance that increases the energy efficiency of buildings by 15% more than the existing San Antonio and Texas state energy codes. This measure incorporated water conservation and other green building elements for all new construction, additions and substantial renovations in the city. The ordinance will make San Antonio the third major city to adopt advanced energy codes in Texas, joining Austin and Houston. The new ordinance will go into effect January 1, 2010, and mark a significant collaborative effort by many stakeholders.

The goal of the Reuse Roadmap is to develop a high-level approach to help guide utilities and industry decision-makers in issues to address when considering water reuse Like the Energy and Nutrients roadmaps, the Water Reuse roadmap is brief and high level to be accessible to all types of stakeholders, including public officials, utility managers, operators, engineers, and regulators The roadmap will not "reinvent the wheel," with all of the great technical resources available. Rather, the focus will be to help decision-makers to quickly understand the strategic issues inherent in a water reuse effort

The relationship between water and energy is a close one. Water requires a tremendous amount of energy to move from a reservoir or well, through the treatment process, and out into a distribution system. In addition, energy is required to process wastewater and recycle or discharge it. The energy required to operate the water and wastewater system is often called embedded energy. Despite this strong connection, the energy intensity of water and wastewater systems is relatively undocumented. There are few data sources and reports analyzing the energy required to move and treat water, and the data generally are not publicly available. ACEEE has been working to gain a better understanding of the energy embedded in water in order to help water utilities reduce costs, improve energy efficiency, and quantify the avoided energy and pollution savings that accrue as a result of water conservation programs. As part of an ongoing effort to advance the understanding of the water-energy nexus and bring attention to possible opportunities, the National Association of Water Companies (NAWC) and the American Council for an Energy-Efficient Economy (ACEEE) collaborated on a new research project to gather primary information on the amount of energy required to treat and distribute water. ACEEE and NAWC jointly produced a survey for NAWC's member companies related to their energy use and water processing. NAWC has over 100 member water and wastewater companies of varying sizes throughout the United States.

Climate change is happening. Past greenhouse gas emissions have committed us to decades of rising temperatures and seas. Recent studies, factoring in ice-sheet melt, estimate that we may experience an average of up to 6 feet of sea-level rise across the globe over the next century. The potential physical and fiscal impacts of sea-level rise (SLR) are stark. We are already seeing increasing erosion of our beaches and the inundation of low-lying wetlands. Physically, SLR will intensify impacts from storm surge, flooding, and erosion. Fiscally, governments will need to spend large amounts of money on emergency response and to rebuild flooded infrastructure. Valuable government tax base and significant private investment will literally fall into the sea. And, if governments fail to plan for these impacts, legal fallout is a certainty.

Green City, Clean Waters represents the City of Philadelphia's (City) commitment to the protection and enhancement of our regional watersheds by managing stormwater with innovative green stormwater infrastructure (GSI), while also helping to revitalize the City. The Philadelphia Water Department (Water Department) developed Green City, Clean Waters to provide a clear pathway to a sustainable future while strengthening the utility, broadening its mission, and complying with environmental laws and regulations. As the City agency charged with ensuring compliance with the Federal Clean Water Act, the Water Department developed an infrastructure management program intended to protect and enhance our region's waterways by managing stormwater runoff in a way that significantly reduces reliance on construction of additional underground infrastructure. At the close of the 25 year implementation period, the Water Department will have invested more than $2 billion on the largest green stormwater infrastructure program ever envisioned in the United States.

Water systems in the United States are among the safest in the world and yet, the fragmented way in which most cities have managed water historically is not viable for handling the serious water challenges confronting urban areas across the nation today and into the future. With climate change driving dramatic changes in the water cycle and rendering traditional approaches to water resources planning obsolete, the time has come for cities to adopt more holistic and resilient water management strategies. Based on the outcomes of an October, 2015 meeting of mayors, municipal leaders and urban water managers, this report encourages the pursuit of integrated water management as a pathway to addressing urban water challenges within and beyond city limits. The report explains the concept of integrated water management; illustrates the potential benefits of pursuing its implementation; and provides practical guidance about steps elected officials, water utility managers, and other municipal leaders can take to get started.

The Local Government Climate and Energy Strategy Series provides a comprehensive, straightforward overview of green-house gas (GHG) emissions reduction strategies for local governments. Topics include energy efficiency, transportation, community planning and design, solid waste and materials management, and renewable energy. City, county, territorial, tribal, and regional government staff, and elected officials can use these guides to plan, implement, and evaluate their climate change mitigation and energy projects.

There is significant potential for gains in energy efficiency (EE) in the U.S. water sector that, if realized, would support the security of water supply for its various uses at a lower cost over the long run than business as usual. This paper specifically examines the potential benefits of and barriers to EE implementation in the publicly-supplied water sector in the United States. The paper addresses this specific piece of the water sector to provide a focus on areas where local governments and municipal water utilities operate and can directly and quickly effect change. I examine the potential for EE along each stage of the public water cycle. Using case studies of communities that have tried to improve EE in their water sectors, I discuss the incentives and disincentives to implementing energy efficiency policy in the public water sector and assess the success of several water utility EE programs. I conclude with a recommendation for local government leaders and water utility administrators to collaborate on designing and financing energy efficiency measures in the public water system.
