Application of water retention crystals to all beds
during planting
Investigate stormwater harvesting opportunities
for garden bed irrigation
Save up to 10% water use on each
bed. Hard to quantify due to yearly
climatic variations and gardens
beds are not separately metered
Dependant on beds selected

DTQ ^ Require new developments within the Potential to lower mains water
municipality to consider water reduction
consumption through reuse of
opportunities and water quality issues.

maintenance actions are dependant on rainfall therefore annual variations in water savings are expected.
