The document discusses rainwater recycling systems for managing stormwater. It summarizes the benefits of rainwater recycling including compliance with stormwater ordinances, cost savings, and sustainability. It then provides details on system components, design considerations, installation, and case studies. Residential and commercial examples are given to illustrate how rainwater can be collected and used for irrigation, flushing toilets, and other non-potable needs while reducing stormwater runoff.

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.

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

5. AVAILABILITY ANDUSEANALYSIS |AvailabilityHow much rainwater can be collected?Rainwater is most commonly collected from roof runoff. Two factors that determine collection potential:1. Local rainfall characteristics 2. Size of the collections surface – roof s.f. 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

6. AVAILABILITY ANDUSEANALYSIS |UseHow can you best use the collected water?Potential uses for recycled water include (but are not limited to):Irrigation (usually accounts for about 60% of overall usage)Flushing ToiletsWashing LaundryWashing VehiclesGeneral MaintenanceDrinking (with proper filtration)

9. SYSTEMDESIGN ANDENGINEERING|Every Raincycle system has a storage component and a water handling component. Proper sizing and configuration of both components is necessary for a sustainable rainwater recycling system. The BALANCE between having too much EMPTYstorage space and having too much OVERFLOWEvery system according to the specific project needs.

10. SYSTEMDESIGN ANDENGINEERING|StorageTank 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.Tanks of varying construction can be located above or below ground to fit project needs. Proper tank size is extremely important and our proven sizing software that sizes systems to a 90% efficiency is a key technological asset.

14. SYSTEMDESIGN ANDENGINEERING|Water HandlingThe German-engineered Wisy filters are the most effective rainwater recycling filters on the market and require minimal maintenance. WisyCleans water of organic matter and debrisFilter only needs cleaning once a yearStainless steel filters do not need replacingTanks need minimal maintenance and cleaningCompetitor’s filterCleans water of organic matter and debrisFilter needs to be cleaned frequently (often after heavy rainfalls)Components more susceptible to wear and tear & filters need replacingTank recommended to be cleaned once a year

15. SYSTEMDESIGN ANDENGINEERING|Vortex Filter

16. VORTEX FILTER|

17. SYSTEMDESIGN ANDENGINEERING|Downspout FilterBoth the Vortex and Downspout filters are tested to collect over 90% of the passing rainwater.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.
