This requirement was first established through the Water Conservation Act of 1991. During the 2004 legislative session, the State of Colorado revised the minimum requirements of the Water Conservation Act of 1991 in House Bill 04-1365. This House Bill now requires the conservation plans to include the following information: The steps the covered entity used to develop, and will use to implement, monitor, review and revise its water conservation plan; The time period, not to exceed seven years, after which the covered entity will review and update its adopted plan; and Either as a percentage or in acre-foot increments, an estimate of the amount of water that has been saved through a previously implemented conservation plan and an estimate of the amount of water that will be saved through conservation when the plan is implemented. The April 1992 Water Resources Management Plan outlined conservation as a viable method to extending water supply. In June 1996, the Town of Castle Rock adopted a water conservation plan that set water conservation goals for the community. In December 2006, the Town of Castle Rock adopted the 2006 Water Conservation Master Plan. Numerous factors require the plan to be updated including: CWCB’s efforts in developing and implementing the Colorado Water Supply Plan; The projected population

  • Taking an Integrated Approach to Improving Water Efficiency
    TECHNICAL BRIEF 4 Taking an integrated approach to improving water efficiency Do you see a pressing need for a realistic evaluation of water-use efficiency options in your country? Are you wondering exactly how your country can fulfill the “water efficiency” part of the WSSD target on the preparation of Integrated Water Resources Management (IWRM) and Water Efficiency Plans and use these to catalyze further improvements? This brief approaches the question of efficiency from an IWRM perspective, aiming to help policy makers and practitioners develop a strategic and integrated approach to improving efficiency. It builds on the discus- sion of water efficiency in Catalyzing Change, the GWP’s handbook for developing IWRM and water efficiency strategies, and emphasizes that efforts to improve effi- ciency should be directly linked to a country’s overall development goals. Committee (TEC) Technical Improving water efficiency allows countries to reduce water scarcity and maximize the benefits provided by existing water infrastructure. It also frees up water for other uses and reduces environmental degradation. Efforts to improve water efficiency can therefore contribute directly to the development goals of many countries, especially those that are chronically short of water or the capital to invest in water development. In 2002, the need to improve water efficiency was recognized and given new impetus by the World Summit on Sustainable Development (WSSD). Article 26 of the WSSD Plan of Implementation, which sets an action target for the preparation of “IWRM and water efficiency plans” by 2005, makes reference to water efficiency in two different ways: • Art. 26 (a): “… introduce measures to improve the efficiency of water infrastructure to reduce losses and increase recycling of water” • Art.

A survey is presented of current analysis methods and tools generally available to industry to analyze environmental impact of, and to manage, water use. These include life cycle analysis, water footprinting, strategic planning, water auditing, and process integration. It is identified that the methods surveyed do not provide insight into the operational requirements from individual process steps for water, instead taking such requirements as a given. We argue that such understanding is required for a proactive approach to long-term water usage reduction, in which sustainability is taken into account at the design stage for both process and product. As a first step to achieving this, we propose a concept of water usage efficiency which can be used to evaluate current and proposed processes and products.

  • Saving Water in Office Buildings
    Commercial and institutional buildings use a large portion of municipally supplied water in the United States. With so many businesses making up the commercial and institutional sector, there are great opportunities to conserve water. WaterSense at Work: Best Management Practices for Commercial and Institutional Facilities promotes water-efficient techniques that can be applied across a wide range of facilities with varying water needs. Water used in office buildings accounts for approximately 9 percent of the total water use in commercial and institutional facilities in the United States.1 The three largest uses of water in office buildings are restrooms, heating and cooling, and landscaping. reducing operating costs, as well as meeting sustainability goals. In addition to water savings, facilities will see a decrease in energy costs because of the significant amount of energy associated with heating water. Energy saved from reducing the amount of water supplied will not only save money, but reduce the Created by analyzing data from: New Mexico Office of the State building’s carbon footprint as well.

  • Water Efficiency Building Design for a Sustainable Future
    Water Efficiency Building design for a sustainable future This fact sheet explains what you can do to conserve Victoria’s precious water resources by using it more efficiently and in certain circumstances substituting drinking water with other sources of recycled water such as rainwater. Even minor changes and installations can save you money, future proof your property investment and increase the amount of water available on your property. What’s included in this fact sheet: • Why do we need to adjust our water usage? • How will improved Water • Efficiency benefit me? • What can I do to use water more efficiently? • Water efficient fixtures and appliances • Rainwater reuse • Greywater reuse • Applying rainwater and greywater • Where can I find out more? • Mandatory Requirements Council’s best practice standard. Why do we need to adjust our water usage? The average Melbourne household of four people uses approximately 240,000 litres of drinking water each year. That’s equivalent to 3000 bathtubs or 10% of an Olympic size swimming pool. In fact, up to 90% of that water consumption is used for toilet flushing, garden irrigation and other uses that don’t require water of drinking quality. Looking at it another way, the average household flushes fresh drinking water equivalent to 80 litres of milk or nine slabs of beer down the toilet every day. With our population growing and weather patterns shifting, we need to rethink the availability of fresh water and prepare for a more efficient use of available resources. How will improved Water Efficiency benefit me? There are many benefits to using water more efficiently.
