Treated wastewater from off-site treatment plants can be re-used for irrigation of parks and gardens, agriculture and horticulture, tree plantation and aquaculture. These can be established not far from the wastewater treatment plants.
For these purposes the wastewater should generally be treated to secondary wastewater standard (< 20 mg/L BOD and < 30 mg/L SS). Total coli forms should be < 1000 organisms per 100 mill for irrigation by spraying. When sub-surface irrigation is used this requirement may not be necessary.
Irrigation of vegetables for direct human consumption requires a much stricter guideline.
Because requirement of wastewater for plant growth is governed by climatic conditions, soil and plant type, there may be a need for storage of the wastewater.
