How to thrive in a Vancouver drought

Locals who have the good sense to use their grey water or captured rain water to keep their gardens green and lush may have to post a sign explaining their environmentally savvy system to watering vigilantes.
Green vegetation is not necessarily the result of treated drinking water from one of our depleted reservoirs; it could — and in many cases should — be nurtured by second-use household water.
A grey water system may be as simple as washing dishes in a dishpan, then tossing the rinse water onto plants. Rain water catchment is still a novelty in the city but all the climate statistics show that the day may come when all households with have access to gutters will need to install a rain barrel to save all that rain for a sunny day.
For the convenience of those who are confused over what can be watered with the city's supply of treated drinking water, check out this chart from the City of Vancouver's own website:
