To use less water:

Cluster plants together and mulch them with compost to conservemoisture.

Avoid planting or transplanting during the summer.

Water in the early morning instead of mid-day so that less waterevaporates.

Water once deeply rather then several times lightly to encourage thedevelopment of deep roots.

Use a rain gauge and timers to avoid over watering.

Pollutant Removal Mechanisms


104/126

Absorption to soil particles

Removes dissolved metals andsoluble phosphorus

Plant uptake

Removes small amounts of

nutrients

Microbial processes

Removes organics and pathogens

Exposure to sunlight and dryness Removes pathogens

Infiltration of runoff

Provides flood control,

groundwater recharge, and

nutrient removal

Sedimentation and filtration

Removes total suspended solids,

floating debris, trash, soil-bound

phosphorus, some soil-bound

pathogens

NOTE: 90% of all storm events

produce less than 1 inch of rain.

Therefore, the key to reducing

pollutant loads is to treat the runoff

associated with the first 1 inch of rain(Clayton & Schueler, 1996).

Rain Gardens/Bioretention

Systems


105/126

Systems

Stormwater runoff entering the bioretention system is filtered firstthrough the vegetation and then the sand/soil mixture before beingconveyed downstream by the underdrain system.

They can be installed in lawns, median strips, parking lot islands,

unused lot areas, and certain easements. They are intended to receive

and filter storm runoff from both impervious areas and lawns.
