The Foundation for Restorative Design “Begins with Water“
Water is the Driver of Life
Re-circulation throughevapo-transpiration
Shallow ground water flow
Aquifer recharge
Constant, clean discharge flows, year round to sustain stable surface water hydrology with constant water temperature and chemistry
Water in Contemporary Urban, Suburban & Rural Environments
Traditional Stormwater Management Approach:Collect and convey water away from the site just as quickly and efficiently as the law will allow through enclosed storm sewer systems designed with concentrated points of discharge that generate a velocity and volume of flow that is nearly impossible to mitigate.
According to USEPA, 40-60% of nitrogen applied to lawns ends up in surface and groundwater systems
Reversed hydrological pattern results in runoff containing sediments, oils, greases, salts, fertilizers, pesticides, and higher water temperatures that inundate historical systems adapted to completely different hydrological and water quality conditions
Contemporary HydrologyUpland becomes discharge zoneNatural wetlands are expected to function as recharge zones

Ask Cooper about the Geothermal labeling. I don't believe it is a "Heat Transfer Main"I would eliminate the storm line. We are not running perf pipe down the road and instead letting the water run through the gravel until the end of the block where we pick up the flow in a perf pipe perpendicular to the road (which you don't need to show)Leave the actual tubing but delete the label that says geothermal tubing due to the political issues. Also, FYI, they were actually snowmelt tubing.

In the Midwest, 34” of rain falls annually. 19 gallons per square foot. Nearly 1 million gallons per acre per year. An additional 1% organic matter per acre will hold an additional 16, 000 gallons of water per acre. Midwestern soils have been depleted from 4-6% SOC to 2.0%.
By increasing the water absorption through improved soil quality of all of the cropland in the Mississippi River Basin by just 2”, that water retention would be the equivalent of…

The nutrient inputs create excellent food conditions for phytoplankton blooms, which upon death, create rich food
sources for bacteria. The bacteria consume excessive amounts of dissolved oxygen- resulting in hypoxia and
thus creating dramatic changes in food chain relationships, loss of biodiversity and high aquatic species
mortality.Iowa and Illinois alone are credited with creating as much
as 35% of the nitrogen pollution ending up in the Dead Zone.
Each spring enormous quantities of dissolved nutrients (nitrogen) are transported from the upper Midwest into
the Gulf of Mexico…

In Conclusion -
A New Paradigm in Wastewater Treatment
Audubon Society Corkscrew Swamp SanctuaryNaples, Florida
After channel treatment, the water will be diverted to a lagoon for further polishing by Lagoon Restorers. This low cost, low energy method of water polishing has proven to help meet current as well as emerging EPA discharge parameters for the removal of more complex contaminants of concern such as personal care products, pharmaceuticals, and most recently restorers have proven effective at the removal of petroleum hydrocarbons. The floating restorers can be sized and configured to accommodate any volume of wastewater discharge and incorporated into a wide range of lagoon types and shapes. This versatility facilitates the use of restorer systems as an integral component of a whole new concept in wastewater facility design.
