  1. 1. WHEN rain touches down it becomes stormwater; at that point how we manage it defines whether it will become a nuisance or a benefit.  Raincycle designs and installs Rainwater Recycling Systems to better manage stormwater on residential and commercial properties.<br />

  3. 3. STORMWATER MANAGEMENT|<br />Current Ordinances: <br />Beaufort County :<br /><ul><li>Newly developed or redeveloped sites must detain first 1.95 inches on rain on the property.</li></ul>Chatham County: <br /><ul><li>Newly developed or redeveloped sites must detain first 1.20 inches on rain on the property.</li></ul>Charleston County:<br /><ul><li>Maintain pre-existing conditions with no increase in run-off</li></ul>(Common Objective)<br />Municipalities also have specific guidelines<br />

  5. 5. AVAILABILITY ANDUSEANALYSIS |<br />Availability<br />How much rainwater can be collected?<br />Rainwater is most commonly collected from roof runoff. <br />Two factors that determine collection potential:<br />1. Local rainfall characteristics <br /> 2. Size of the collections surface – roof s.f.  <br />One inch of rain produces .62 gallons of water for a single square foot area.  Thus a 1,000 square foot roof has the potential to collect 620 gallons of water for every inch of rain<br />
  6. 6. AVAILABILITY ANDUSEANALYSIS |<br />Use<br />How can you best use the collected water?<br />Potential uses for recycled water include (but are not limited to):<br />Irrigation (usually accounts for about 60% of overall usage)<br />Flushing Toilets<br />Washing Laundry<br />Washing Vehicles<br />General Maintenance<br />Drinking (with proper filtration)<br />
  8. 8. COMMERCIAL SYSTEM|<br />
  9. 9. SYSTEMDESIGN ANDENGINEERING|<br />Every Raincycle system has a storage component and a water handling component.  <br />Proper sizing and configuration of both components is necessary for a sustainable rainwater recycling system.  <br />The BALANCE between having too much EMPTY<br />storage space and having too much OVERFLOW<br />Every system according to the specific project needs.<br />
  10. 10. SYSTEMDESIGN ANDENGINEERING|<br />Storage<br />Tank sizing is derived from calculations that follow the Availability and Use Analysis.  These calculations take daily rainfall averages for your specific area along with your demand needs to calculate how much storage your system will need.<br />Tanks of varying construction can be located above or below ground to fit project needs.  <br />Proper tank size is extremely important and our proven sizing software that sizes systems to a 90% efficiency is a key technological asset.<br />

  14. 14. SYSTEMDESIGN ANDENGINEERING|<br />Water Handling<br />The German-engineered Wisy filters are the <br />most effective rainwater recycling filters on <br />the market and require minimal maintenance.  <br />Wisy<br />Cleans water of organic matter and debris<br />Filter only needs cleaning once a year<br />Stainless steel filters do not need replacing<br />Tanks need minimal maintenance and cleaning<br />Competitor’s filter<br />Cleans water of organic matter and debris<br />Filter needs to be cleaned frequently (often after heavy rainfalls)<br />Components more susceptible to wear and tear & filters need replacing<br />Tank recommended to be cleaned once a year<br />
  15. 15. SYSTEMDESIGN ANDENGINEERING|<br />Vortex Filter<br />
  16. 16. VORTEX FILTER|<br />
  17. 17. SYSTEMDESIGN ANDENGINEERING|<br />Downspout Filter<br />Both the Vortex and Downspout filters are tested to collect over 90% of the passing rainwater.<br />Both filters also act as a first flush. The first flow of water that passes across the filter screens is not collected until the screens become wet enough to activate the capillary action that pulls water behind it.<br />
  18. 18. SYSTEMDESIGN ANDENGINEERING|<br />Inside Tank Components<br />A. The Smoothing Inlet prevents tank stirring when the rainwater enters the tank.<br />B. The Multi-Siphon acts as a skimming device and backflow preventer.<br />C. The Floating Suction Filter collects the cleanest water from just below the surface.<br />A.<br />B.<br />C.<br />
