Greywater Recycling Challenge

$260

OBJECTIVE

The Greywater Recycling Challenge is designed to encourage municipalities to revise their laws regarding the use and disposal of a home’s greywater and spur the installation of greywater recycling systems in new and existing homes.

To claim the prize, the participating municipality must demonstrate that the required number of homes according to the Official Tabulation have had greywater recycling systems installed within 18 months of submitting a claim. The number of homes that must install greywater recycling systems is dependant on the size of the municipality and its rate of growth according to the 2000 U.S. Census.

The Official Tabulation has been calculated using either formula #1 or #2 below depending on whichever yields the lowest value for X when rounded to the nearest whole number:

#1) X = 0.115789473684211 * Y + 19.7368421052632

#2) X = Z * 0.0147

X = The number of homes required to be serviced by greywater recycling systems installed in the previous 18 months.

Y = The average number of new homes built in the municipality per year during the 1990s according to the 2000 U.S. Census as calculated by dividing the total number new homes built during the decade by 10.

Z = The total number of homes in the municipality according to the 2000 U.S. Census.

For example, the town of Jefferson, WI grew by 500 homes in the 1990s, or an average of 50 homes per year. According to formula #1, greywater recycling systems would have to be installed in a minimum of 15 homes in the municipality within 18 months to claim the prize. Similarly, Lee’s Summit, MO, which added nearly a 1000 new homes each year, would need to have systems installed capable of recycling the greywater of at least 125 homes.

On the other hand, despite adding a average of 112 homes per year during the 1990s, in Celebration, FL, greywater recycling systems would need to installed in a minimum of 17 homes according to formula #2 since there were 1136 total homes in the municipality according to the 2000 U.S. Census,

To participate, a minimum of 15 homes in the municipality must incorporate greywater recycling systems in the previous 18 months. Up to three adjacent municipalities with an Official Tabulation each less than 15 may jointly participate provided the total number of greywater systems installed in the previous 18 months is equal to or greater than the combined Official Tabulation of the participating municipalities.

Municipalities whose boundaries have been redrawn since the 2000 U.S. Census resulting in a 1% increase or decrease in homes must calculate the number of homes required to be serviced by a greywater recycling system installed in the previous 18 months using the formula provided in the requirements.

A home’s greywater recycling system must be designed to recycle a minimum of 30% of the potable water per home used in the course of one year. A single greywater recycling system may service more than one home (as in the case with an apartment building or townhouse) so long as it is designed to recycle 30% of the building’s potable water.

The first municipality that can demonstrate that greywater recycling systems servicing the required number of homes have been installed in the 18 months prior to submitting a claim shall receive the prize.
