12 Benefits of Rainwater Harvesting Rainwater harvesting systems reduce non-point source pollution such as pesticides, fertilizers and petroleum products that end up in rivers and groundwater. Rainwater Harvesting - MCMGA

13 Benefits of Rainwater Harvesting As decentralized water systems, they contribute to restoration of stream flows and habitats. Integrated on-site water capture reduces the waste and environmental disruption involved in centralized water distribution systems. Rainwater Harvesting - MCMGA

Benefits of Rainwater Harvesting Rainwater catchment systems can replace use of potable water for irrigation, which is the largest use of fresh water in the United States according to the USGS.

14 Benefits of Rainwater Harvesting Rainwater catchment systems can replace use of potable water for irrigation, which is the largest use of fresh water in the United States according to the USGS.7 At home, the average person uses 80 to 100 gallons of water per day, mostly for toilet flushing, followed by bathing.6 Very little of the potable water used in the home is consumed for drinking and eating.

15 Benefits of Rainwater Harvesting Implementing waterefficient technologies in combination with a rainwater harvesting system can eliminate or vastly reduce use of public water supply. Rainwater Harvesting - MCMGA

16 Using Rainwater Drip Irrigation Drip Irrigation Benefits: Reduces or eliminates wasted water No runoff: The water is absorbed by the soil Little evaporation : Water is applied to the plant s root zone No water is lost on sidewalks, driveways, and empty areas Better Plant Health Water applied at the soil level is better able to meet the plant s needs and reduces diseases. With less runoff, your fertilizers and pesticides stay where they are needed. For brackish water sources, drip irrigation reduces leaf damage by not wetting them. Lower home maintenance costs Since the water is not spraying the house and fence, patching and painting is reduced. Windows aren t sprayed so less cleaning is needed Rainwater Harvesting - MCMGA

25 Hill Country Youth Event Center This collection system provides all the water for the 45 indoor and 18 outdoor livestock wash bays, for all the toilets and urinals in the exhibit hall, for dust control in the indoor arena, and to irrigate the native Texas landscaping. By harvesting the rainwater, localized flooding, erosion, and runoff into the Guadalupe River are also reduced

30 Cities using rainwater harvesting In many communities, designers no longer have a choice but to become more proactive about managing water. Many government agencies are mandating that developments capture stormwater. Aging infrastructure cannot handle the flow into sewer systems. In fast-growing Portland, Oregon, which receives more than 40 inches of rain annually, one-third of the sewer pipes are over 80 years old. With a focus on keeping water out of the system, the city requires a stormwater abatement plan for any construction with more than 500 square feet of impervious surface. Rainwater Harvesting - MCMGA

31 Cities using rainwater harvesting Most areas of the United States lag behind international trends. For years, countries in arid climates have been demanding that developments capture and reuse water. For these nations, drought conditions and the lack of available groundwater create constant pressures on supply. Desalination plants and residential water tank systems are necessities.
