Automatic Plant Watering System in New Delhi

With Delhi Jal Board supplying around 900 million gallons of water a day to the capital and groundwater levels still falling, a home or office relying on a borewell or tanker for garden watering draws on a source under real pressure. Drip lines deliver water directly to the root zone rather than across the surface, cutting the volume needed to keep the same beds and lawn alive.

Covering the nine months outside the monsoon

Almost all of Delhi's roughly 774mm of annual rain falls in the four monsoon months from June to September, leaving the rest of the year dependent on whatever water source the garden has. A timer-controlled drip system set up before the dry season means beds and lawn get consistent, metered watering through this stretch even when nobody is home to do it by hand.

Comparing drip use against the alternative

A drip system is usually justified by comparing how much water it uses against a hose or flood-watered bed of the same size, and in a region where the water utility itself flags falling groundwater, that comparison carries more weight than it would in a water-rich city. None of this requires a household or office to track groundwater data itself, only to plan watering with the general knowledge that the region's supply is limited rather than assumed endless, which is exactly what a metered, timer-controlled system is built to do. Cutting back further during a particularly dry stretch is then a matter of adjusting the timer, not redesigning the layout.
