Strategy - 1
Control water falling on the site to use it most effectively and efficiently
Planted areas should be used as a water collector. The surface planting should
prevent rapid run-off and allow for percolation of the falling water into the soil.
This is the surest, least expensive and most environmentally correct strategy to
conserve water and to use available water most efficiently.
This can be done in the following ways:
1. Slow down falling water so that it can be absorbed into the soil.
2. Direct the flow of falling water through proper grading.
3. Channelise falling water into the soil where it falls or where it is required on site.
4. Store the precipitation received on the site. Do not let it to run off the site.
Strategy - 2
Use of Drought Resistant or Drought
Tolerant Vegetation
Basically, the purpose is to replace
water requiring plants in the landscape
with those which require less water and
irrigation.
Strategy - 3
Leave Plants in Stress
Condition
In essence, this strategy
involves just barely
watering the landscape
plants enough to keep
them alive, but not enough
for them to grow and
flourish apart from the
available natural water
resources.
Strategy - 4
Erecting Wing Barriers
The concept is that by
reducing wind speed less
of available water will be
transpired out of the plant
into the atmosphere.

Strategy - 5
Redesign or Renovate to Reduce Water
Requirements
Specific plants which require too much water,
whether it be a tree, a shrub, ground cover or even a
turf variety, may have to be replaced in times of
extreme water Shortage.
This can be done in the following ways:
1. Provide shade by non-vegetative means.
2. Depress turf areas adjacent to walks to hold water.
3. Don’t put trees on turfed berms.
4. In seeking to converse water or to use available
water more efficiently it may be necessary to
regrade to allow water to percolate into the soil
rather than running off.
