  • Transcript of "Rain Water Harvesting As Alternative Water Source"

    1. 1. Rain Water Harvesting as Alternative Water Source “Changes start from inside the Campus” Indonesia Case of RWH Presented by: Toha Saleh Center for Environmental and Water Engineering Research Civil Engineering Department, Faculty of Engineering – University of Indonesia Research Team: Toha Saleh, Elkhobar, Dwinanti, Dwita SM Participated Students: Adi Pauna, Ahmad Dzaky, Robby Regional Conference for Southeast Asia on Rainwater Harvesting in Integrated Water Resources Management: &quot;An Exchange of Practices and Learnings“ 25-26 November 2008, Davao City - Philippines.
    2. 2. Indonesia Facts <ul><li>Rainfall: 200-300 mm/year (more than 2,500 km 3 ) </li></ul><ul><li>Environmental Issues: Flood, Drought, Landslide, Poor Water Quality, Poor Access to Water </li></ul><ul><li>People: Activities, Habits, Politics, Coordination </li></ul>Region Yearly Rainfall (mm) South part of Gunung Slamet (Central Java) 4.000 Bogor (West Java) 3.200 Sumatera 2.300 Malang (East Java) 2.000 Nusa Tenggara (Next to Timor Leste) 1.000 Palu (Central Sulawesi) 546
    3. 3. Understanding the IWRM Water is the basis for all living ecosystems and habitats and part of an immutable hydrological cycle that must be respected if development of human activity and well-being is to be sustainable. A holistic, systemic approach relying on Integrated Water Resources Management (IWRM) must replace the fragmentation that currently exists in managing water
    4. 4. The Need of IWRM <ul><li>As a tool towards </li></ul><ul><li>Proper water management </li></ul><ul><li>Adaptation to climate change </li></ul><ul><li>Achieving MDGs </li></ul><ul><li>Knowledge transfer for next generation </li></ul><ul><li>Plan to sustainability </li></ul>
    5. 5. Rainwater Harvesting <ul><li>Reduce Runoff </li></ul><ul><li>Preserve Groundwater </li></ul><ul><li>Reduce Environmental Losses </li></ul><ul><li>Lessen Drought Period </li></ul><ul><li>Plan to sustainability </li></ul>As part of Low Impact Development (LID) Approach
    6. 7. Low Impact Development <ul><li>An innovative, ecosystem-based approach to land development and stormwater management </li></ul><ul><li>To mimic predevelopment site hydrology, by considering local natural environment & limitations, through introduction of site design techniques  effects of development will be minimal </li></ul>
    7. 8. Why We Need Low Impact Development <ul><li>To better protect our: </li></ul><ul><ul><li>Streams </li></ul></ul><ul><ul><li>Fish and wildlife habitat </li></ul></ul><ul><ul><li>Watershed hydrology </li></ul></ul><ul><ul><li>Drinking water </li></ul></ul><ul><ul><li>Water quality </li></ul></ul><ul><li>To reduce infrastructure costs </li></ul><ul><li>To make our communities more attractive </li></ul>
    8. 9. Primary Goal of LID Design each development site to protect, or restore, the natural hydrology of the site so that the overall integrity of the watershed is protected. This is done by creating a “hydrologically” functional landscape.
    9. 10. Basic LID Principles <ul><li>1. Conserve natural areas </li></ul><ul><li>2. Minimize development impacts </li></ul><ul><li>3. Maintain site runoff rate </li></ul><ul><li>4. Use integrated management practices </li></ul><ul><li>5. Implement pollution prevention, proper maintenance and public education programs </li></ul>Low-Impact Development Design Strategies (An Integrated Design Approach) , Prince George.s Country, Maryland. Department of Environmental Resources Programs and Planning Division. June 1999.
    10. 11. LID Implementation <ul><li>Identify and develop applicable regulations and requirements </li></ul><ul><li>Use drainage/hydrology as a design foundation </li></ul><ul><li>Allow designs that reflect conservation plans </li></ul><ul><li>Reduce site imperviousness and minimize directly connected impervious areas </li></ul><ul><li>Use sustainable integrated management practices </li></ul><ul><li>Develop pollution prevention, maintenance, public outreach and education programs </li></ul>
    11. 12. Conservation Open Drainage Rain Gardens Amended Soils Rain Barrel Reduced Imperviousness LID Site Porous Pavement Create a Hydrologically Functional Lot
