Dhwms Company Project Presntation Nov 8, 2007

  1. 1. DH Water Management Future Irrigation Design is Here
  2. 2. DHWMS Vision <ul><li>To be Industry leaders in: </li></ul><ul><li>Sustainable Irrigation Design Using… </li></ul><ul><li>“ Off the grid water” </li></ul>
  3. 3. Our Clients <ul><li>Architects </li></ul><ul><li>Engineers </li></ul><ul><li>Landscape Architects Municipalities </li></ul><ul><li>Water Purveyors </li></ul><ul><li>Developers </li></ul><ul><li>Planners for Urban Developers </li></ul><ul><li>Sports & Recreation Developments </li></ul><ul><li>Master Plan Community Developers </li></ul><ul><li>Commercial & Residential Property Managers </li></ul>
  4. 4. Our Services <ul><li>From conception to completion…DHWMS Professionals collaborate with you, one project at a time. </li></ul><ul><li>Consult, Design, Manage, Educate </li></ul><ul><li>Focused on positive outcomes </li></ul>
  5. 5. Our Teams Credentials & Memberships <ul><li>Fully certified in every aspect of irrigation … we are the forward thinkers </li></ul>
  6. 6. Styles of Irrigation <ul><li>Traditional </li></ul><ul><ul><li>Sprays and rotors </li></ul></ul><ul><li>High Efficiency </li></ul><ul><ul><li>Spacing, Pressure management, Subsurface, point source, deep root watering </li></ul></ul><ul><li>LEED </li></ul><ul><ul><li>Rainwater, stormwater, reuse water (greywater) </li></ul></ul><ul><ul><li>Green Roof, Green Wall, temporary systems </li></ul></ul>
  7. 7. Traditional System Sprays Impacts Rotors
  8. 8. Traditional Irrigation <ul><li>Also called Conventional Irrigation </li></ul><ul><ul><li>Overhead spray and rotor sprinkler systems. </li></ul></ul><ul><ul><li>Controlled by an irrigation timer that activates electric valves on a time basis. </li></ul></ul><ul><ul><li>Automatic systems are connected to a rain sensor. </li></ul></ul><ul><ul><li>Backflow prevention devices are installed to protect potable water sources. </li></ul></ul><ul><ul><li>Sprinkler head spacing is key. </li></ul></ul>
  9. 9. Sports Fields – The Right Way <ul><li>Good design = good outcome </li></ul><ul><li>Plan for success </li></ul><ul><li>Know your water source </li></ul><ul><li>Hydraulically sound design is key </li></ul><ul><li>Proper sprinkler head spacing is a must </li></ul>
  10. 10. Sports Fields – Designed for Field Maintenance. <ul><li>Football </li></ul><ul><li>Soccer </li></ul><ul><li>Water from the center high play areas to less used areas. </li></ul><ul><li>Facilitates ongoing maintenance of fields. </li></ul>
  11. 11. High Efficiency Irrigation
  12. 12. High Efficiency Irrigation <ul><li>Low Volume also known as Drip Irrigation … </li></ul><ul><ul><li>Low volume emitters utilize water in gallons per hour (GPH) rather than gallons per minute (GPM). </li></ul></ul><ul><ul><li>Point source watering: </li></ul></ul><ul><ul><ul><li>for shrubs and deep root watering for trees… on their own stations (zones). </li></ul></ul></ul><ul><ul><li>Broadcast or dripline: </li></ul></ul><ul><ul><ul><li>Low volume drip watering of mass plantings (micro sprays,sub surface or below mulch.) </li></ul></ul></ul><ul><ul><li>Narrow Turf Strips: </li></ul></ul><ul><ul><ul><li>Subsurface dripline at 4” depth. (do not aerate.) </li></ul></ul></ul>
  13. 13. High Efficiency For Trees Root watering system – 18”, 12”, & 6” depths Micro bubbler on surface: own station.
  14. 14. MN Zoo Project <ul><li>Designing around Grizzly bears, Leopards, Wild Boar and other animals. </li></ul><ul><li>What does it look like? </li></ul><ul><li>How was it done? </li></ul>
  15. 15. MN Zoo - Views
  16. 16. MN Zoo <ul><li>Point source, Dripline, Conventional sprays, Golf rotors, HDPE mainline. </li></ul>
  17. 17. Master Planned Communities <ul><li>Utilize on-site water via rain water collection into pre constructed basins </li></ul><ul><li>Design with specific system efficiency </li></ul><ul><li>Create an irrigation standard for efficient community development </li></ul>
  18. 18. Residential High Efficiency <ul><li>Sub-surface drip line along blvd. </li></ul><ul><li>Drip tubing mulched under shrubs & planting beds. </li></ul><ul><li>Root watering systems for new trees and hedges. </li></ul><ul><li>MP Rotators in turf areas. </li></ul><ul><li>Green roof watering system (not shown). </li></ul>
  19. 19. LEED Irrigation Scoring Water Points <ul><li>Leadership in Energy and Environmental Design. </li></ul><ul><ul><li>High efficiency irrigation system with… </li></ul></ul><ul><ul><li>Rainwater Harvesting and/or… </li></ul></ul><ul><ul><li>Rain Gardens where outflow needs control </li></ul></ul><ul><ul><li>Stormwater Harvesting and/or… </li></ul></ul><ul><ul><li>Graywater Harvesting </li></ul></ul>
  20. 20. Green Roof <ul><li>A green roof is a green space created by adding layers of growing medium and plants on top of a traditional roofing system. </li></ul><ul><ul><li>Reduce storm water run off, heat island effect & filters pollutants and CO2 out of the air. </li></ul></ul>
  21. 21. Soldier Field, Chicago Award-winning green roof design Roof top garden North Burnham Park Redevelopment Chicago, IL Award of Excellence, 2004
  22. 22. Green Roof Subsurface Dripline Cover with mulch – space 12” - 18” triangular pattern Sub-surface dripline beneath sod. Test water distribution before laying sod.
