Field studies were undertaken in recent years to confirm the hypothesis that treated secondary wastewater can be disposed by using it in drip systems for irrigation of edible crops. This hypothesis was examined in field experiments conducted with the treated domestic wastewater of the city of Beer-Sheva, Israel. The results indicated that contamination of the soil surface and plants was minimal when subsurface drip irrigation was applied, but maximal when sprinkler irrigation was utilized.

Field experiments were conducted to evaluate the reuse of domestic, secondary treated wastewater for irrigation of edible crops. Corn was irrigated under on-surface and subsurface trickle systems with effluent and compared with on-surface trickle irrigation applying fresh water. The results indicate that under sub-surface trickle irrigation fruit contamination is minimal.

Trickle systems can be implemented for domestic effluent disposal and reuse for irrigation of edible crops. This hypothesis was examined in field experiments conducted recently with the treated domestic wastewater of the city of Beer-Sheva, Israel. The results indicate that minimal soil surface and plant contamination was detected under subsurface trickle irrigation and maximal under sprinkler irrigation.
