Automatic Plant Watering System in Bangalore

Where a home or office runs its irrigation off borewell water from Bangalore's hard-rock aquifer, we fit a filter ahead of the drip line, since clearing scale out of dozens of narrow emitters after the fact costs far more in labour than filtering the water once at the source.

Cauvery-fed municipal connections, covering roughly 80% of the city's piped supply, generally need lighter filtration, since surface water carries less dissolved mineral than water drawn from granite bedrock.

Scheduling around two monsoons and a dry stretch

The timer's schedule is set for three distinct periods: the southwest monsoon from June to September, the shorter northeast monsoon in October and November, and the drier months from December to May, so the system waters less during the two rain spells and more consistently through the dry stretch.

The Arkavathy river, which supplies close to a fifth of the city's piped water through the Thippagondanahalli and Hesaraghatta reservoirs, has also seen its water quality affected by effluent discharge over the years, which is a further reason we treat municipal supply with a basic filter stage rather than assuming any piped source is drip-line-clean by default.

Sizing the system to the household's actual demand

Given how much the city's overall water demand outpaces supply, a drip system sized generously but run on a smart timer generally uses less water over a year than manual watering with a hose, which is worth setting out plainly in the proposal since some households assume automation means using more water rather than less.
