Webb April 2009 Major: Civil Engineering iii ABSTRACT Implementing Rainwater Harvesting Systems on the Texas A&M University Campus for Irrigation Purposes: A Feasibility Study. (April 2009) William Hall Saour Department of Civil Engineering Texas A&M University Research Advisor: Dr. Emily Zechman Department of Civil Engineering Increasing population and increasing urbanization threatens both the health and availability of water resources. The volume and timing of water that is readily available may not be sufficient to supply the demand for potable water in urban areas. Rainwater harvesting is a water conservation strategy that may help alleviate water scarcity and protect the environment. The benefits of collecting rainwater and utilizing it as irrigation water are both tangible and non-tangible. Through collecting and reusing rainwater, grey water may be utilized as a practical resource. Although grey water is not safe to drink, it is safe for other uses such as toilet water, cleaning water, and irrigation.

    DRINKING WATER QUALITY IN THE HOME Responses to Frequently Asked Questions About Lead and Copper in Water 1. What steps can I take to maintain drinking water quality in my home? Residents can take steps to protect water quality in their home. Actions that help to preserve water qual- ity include: • Use cold water for drinking and preparing food. • Flush your tap before using it for drinking or cooking any time the water in a faucet has gone unused for more than 6 hours. Flushing the tap means running the cold water for 30 seconds to 2 minutes until it gets noticeably colder. • Clean faucet aerators and strainers monthly. Replace aerators in poor condition. • Clean and disinfect sinks and faucets regularly. Cleaning faucet aerators monthly and running cold water to - flush a faucet that hasn’t been used for 6 or more hours help cording to the manufacturer’s recommendations. preserve drinking water quality in your home. • Replace your refrigerator and icemaker filters ac the manufacturer’s recommendations. • Corrosion may be greater if grounding wires from • Replace any other water filters used according to the electrical system are attached to your pipes.

    AUTHOR: Carol Boyle, Director, International Centre for Sustainability Engineering and Research, University of Auckland Marya Mahmood (MEngSt Student, University of Auckland) Title of Paper: Comparative Assessment of Embodied Energy and CO2 of Water Tanks Contact Dr. Carol Boyle Organisation International Centre for Sustainability Engineering and Research University of Auckland Postal Address Private Bag 92019 Auckland 1072 Telephone 649 373 7599x88210 Fax 649 373 7462 Email [email protected] 1 Abstract The main aim of this project was to compare the life cycle energy use and carbon dioxide emissions of different materials of water storage tanks for a New Zealand market. This study analysed the life cycle analysis energy requirements and carbon dioxide emissions associated with plastic, concrete, steel and wood water storage tanks. The energy inputs and emissions for each of the materials were normalised to the 20 years. Results indicate that wood was the best of the four materials, having both the lowest embodied energy and carbon dioxide emissions. Plastic had the highest embodied energy while concrete tanks had the greatest embodied CO2. Further research is required to complete a full life cycle assessment of the different materials. 2 Environmental Impacts of Different Materials for Water Tanks Introduction There are increasing concerns over provision of water to communities, with an estimated two-thirds of countries facing increasing water shortages by 2050 (GEO4, 2007). While much of New Zealand current has sufficient water, changes in rainfall patterns due to climate change, an increasing consumption of water and a reliance on water for energy provision mean that water conservation will become increasingly important.

  • Wood Burning Cook Stove Energy Saving Hot Water Kit CAUTION
    INSTALLATION INSTRUCTIONS For The "North" Wood Burning Cook Stove energy saving Hot Water Kit CAUTION: These installation instructions are meant to be used as a guide for woodstove owner and plumber to follow. Failure to follow these instructions properly may result in a faulty installation. which could result in damage to system and/or self. Study the instructions thoroughly before beginning any work. WARRNING: Water Coil should be installed over horizontal firebricks and under cooktop (horizontally as shown on photo 1 and 2 on pg.6) NOT inside the firebox. USE PROFESSIONAL-LICENSE PLUMBER. If your unit has water coil installed by manufacturer, skip 1-7 and choose method I, II or III, one that will best suit your particular needs. 1. Wash the heat exchanger coil out with hot soapy water and rinse. This will insure that no residues will be left inside the coil from the manufacturing process. 2. Measure the distance from center to center of the holes on the ends of the heat exchanger coil. This measurement may be 6", 8", or 9“, depending on your coil kit model no. 3. Locate a space within the stove where the coil will not interfere with any of the internal parts. With a centerpunch and hammer, mark two points (measurement in step one) on the outside of the stove that will correspond with the free space inside. If your stove is cast iron, DO NOT attempt to centerpunch it, as it will crack. Mark the stove with a felt tipped pen if it is cast iron. 4. With the drill provided in the holesaw, dril a 1/4" hole at each of the marks.

  • Harvesting Rainwater for Use in the Garden
    EM 9101 • December 2014 Harvesting RAINWATER Sam Angima for use in the garden ainwater harvesting is the capture, diversion, and storage of rainwater for a number Rof different purposes. Although water is publicly owned in Oregon, state law allows residents to collect runoff from rooftops and store it in reservoirs, rain barrels, water tanks, or other containers. For those with small acreage property Roof (ideally, less than 1 acre), harvested and stored Gutter rainwater can cut city and well-water consumption by providing an alternative source for irrigating landscapes, vegetables, or small fruit gardens. Other than the initial cost of installing a Cistern catchment and pumping-and-delivery system, Roof washer rainwater is free.

  • Plastic Water Storage Tank
    Profile No.: 58 NIC Code: 22208 PLASTIC WATER STORAGE TANK 1. INTRODUCTION Polyethylene water storage tanks are ideal for economic and hygienic storage of potable water in residential buildings, industrial units, business complexes, in fact anywhere and everywhere. These tanks are moulded in one piece. Water storage tanks are without any seams, joints or welds. Because of their light weight, these tanks are easy to install and are extremely mobile. They are very light for the volume of water stored. A tank capable of storing 2000 litres of water weighs only 65 kgs. as against 0.5 MT in case of M.S. tank and 2 MT in case of RCC tank of a similar capacity. These tanks are rust proof and leak proof. Hence they practically require little or no maintenance. These tanks have double the life than that of RCC tanks and three to four times than that of M.S. tanks. The temperature of water inside is maintained for a considerable longer time than an M.S. tank because polyethylene is a bad conductor of heat. 2. PRODUCTS AND ITS APPLICATION A water tank is a container for storing water. The need for water tanks is as old as civilization. Tanks were used to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression, agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. 3. DESIRED QUALIFICATION FOR PROMOTER The Promoter should have preferably a basic degree in plastic engineering/ processing or a degree/ diploma in engineering / or a degree in chemistry.
