reed bed considerations: [horizontal,
vertical, or combo]
+ environmentally safe, effective treatment
+ no by-productsŠno noise or smell
+ long lasting, wear-free, naturally regenerative
- space availability or
limitations for simple system
[+/-
20sf/person needed, assuming greywater only]
- safety issues
introducing wetland or
body of
water into urban landscape
functions of plant:
€extensive root system provides channels for
the
water to
pass through, keeping soil open
resulting
in constant
growth
of root system
2.introduce oxygen down into the body of soil,
providing
an environment where aerobic bacteria
can
thriveŠneeded for the effective breakdown
of many
types of compounds
3.plants are capable of taking up a certain amount
of nutrient from the
wastewater
themselves
