Rainwater Harvesting Systems / RWH Projects
Rainwater Harvesting Systems (RWH) are sustainable water management solutions designed to
collect, store, and utilize rainwater for various applications, including domestic,
industrial, agricultural, and commercial use. These systems help conserve water resources,
reduce dependency on groundwater, mitigate urban flooding, and promote environmental
sustainability. RWH is particularly beneficial in regions facing water scarcity, as it
provides an alternative and renewable water source.
The basic working principle of a rainwater harvesting system involves capturing rainwater
from rooftops, open surfaces, or natural catchments and directing it through a filtration
system before storage or direct usage. There are two main types of rainwater harvesting
systems: surface runoff harvesting and rooftop rainwater harvesting. Surface runoff
harvesting collects water from open areas such as roads and fields, directing it to storage
reservoirs, recharge pits, or infiltration wells. Rooftop harvesting, on the other hand,
involves collecting rainwater from building rooftops using gutters and downpipes, filtering
out debris, and storing it in underground tanks, overhead reservoirs, or recharging it into
the groundwater.
