areas with low to moderate contamination potential that represent opportunities for [[Rainwater Harvesting| rainwater harvesting]], [[permeable pavements]] and other stormwater infiltration practices. Furthermore, it is important to ensure that relatively clean runoff is not mixed with lesser quality runoff from surfaces that are subject to higher levels of contamination, rendering it less suitable for infiltration or harvesting. | areas with low to moderate contamination potential that represent opportunities for [[Rainwater Harvesting| rainwater harvesting]], [[permeable pavements]] and other stormwater infiltration practices.
