What exactly is stormwater?

mechanical biological

STORMWATER is the water that drains ofg a land area from

rainfall. This includes rain that falls on roofuops, directed

through gutters and downpipes onto land or into drains, as well as rain falling on ground surface areas such as roads, driveways, footpaths, gardens and lawns. RAINWATER refers only to the rain that falls on the roof, which can be harvested into a storage tank prior to contact with the ground.

STORMWATER is defined by the US EPA “as the runofg generated when precipitation from rain and snowmelt events flows over land or impervious surfaces without percolating into the ground.”

LID

Overview

Buildings present ready opportunities for harvesting

stormwater runoff from roofs through small-scale embedded

technologies. LID facilities are one aspect of “smart building”

development that optimize feedback between environment and building to achieve net energy production, or regenerative development (versus sustainable development, which is carbon neutral). LID facilities are chosen according to the level of ecological service desired. The simplest service is groundwater recharge from roof stormwater runoff. Gutters and leaders that channel rainwater create concentrated discharges and are avoided in favor of devices that slow, spread, and soak rainwater throughout the site. A higher level of service involves vegetated or green roofs, which absorb and evaporate rainwater through a cultivated plant and soil community. Green roofs are superior building insulators, minimizing heating and cooling demands. Green walls minimize solar gain during the summer and wind loading during the winter. Rainwater harvesting offers three basic levels of service, involving storage cisterns with options for treatment. The simplest service is rainwater reuse for outdoor landscape

irrigation. A more complex harvesting service incorporates a

greywater building supply with additional treatment for non- potable water uses like toilet flushing and landscape irrigation. The highest level of service involves harvesting for potable (drinking) water which requires UV light disinfection for a private water system, and when combined with water from a public utility includes proper back-flow prevention. Placement of LID facilities on a building site should be carefully considered. Infiltration and treatment facilities can be used next to a building to capture roof runoff. Infiltration facilities, however, should be located at least 10 feet away from buildings, as they may cause the shrinking and swelling

f soils, which can negatively affect foundations.

IV. DISCUSSION: Share Your Feedback on the Selected Criteria

What are Madera’s most critical challenges?

What criteria matter most in Madera County?

https://answergarden.ch/506626

The Facilities Menu organizes the LID facilities based on increasing level of treatment service (quality) as well as increasing level of volume reduction (quantity). Therefore, number one (1), flow control devices offer the least amount

f treatment services while number twenty-one (21),

constructed wetland offers the most. Most municipalities require drainage infrastructure to manage 100-year storm

events. Though one facility alone will likely not satisfy

performance requirements, facilities with varying levels of service in a treatment network will provide superior levels

f treatment and volume reduction.
