An introduction - About Rainwater Harvesting

Water is the nectar of life and life cannot sustain without it. Ever increasing demands of water for domestic, irrigation as well as industrial sectors have created a water crisis worldwide. Groundwater is the only dependable source of water. Due to rapid urbanization infiltration of rainwater into the sub – soil has decreased drastically, and the recharging of Groundwater has diminished. Over exploitation of Groundwater resources has resulted in a decline in water levels in most part of the country. Inferior quality of groundwater with high salinity, fluoride, and nitrate contents further limits the availability of freshwater assets. Therefore, it has become essential to adopt Rainwater Harvesting, Artificial Recharge, Storage & Water Shed Management.

Advantages of Rainwater Harvesting

Enhance the availability of Groundwater at specific place and time.

Augment the Groundwater storage and control the decline of water levels.

Replacement of filter media.

Improves the quality of Groundwater through dilution.

Removes bacteriological and other impurities from sewage and wastewater.

Save energy required for lifting the Groundwater and reduce the power consumption of 0.4KWH.

Reduces the runoff which is choking the storm drains.

Reduces the Groundwater pollution.

Meet ever-increasing demand for water in the urban areas.

Reduces the Soil erosion.

To arrest sea water ingress.

The structures required for harvesting the rainwater are simple, economical, and eco-friendly.

Attributes of Groundwater

There is more Groundwater than surface water.

It is less expensive and economic resource.

It is a sustainable and reliable source of water supply.

It is relatively less vulnerable to pollution.

It is free of pathogenic organisms.

It is usually of high bacteriological purity.

There are no conveyance losses in Groundwater-based supplies.

Groundwater resources can be instantly developed and used.

Groundwater has no turbidity or color.

Groundwater has a low vulnerability to drought.

Groundwater is usually universally available.

Methods of Rainwater Harvesting

Recharge through Dug wells

Dug wells that are abandoned as well as dried up can be utilized for recharging the aquifers.Stormwater can be diverted to the dug wells through a de-siltation chamber as shown in the adjacent figure or through a filtration chamber consisting of sand/Gravel/ Boulders if the expected silt load is more in the storm water.

Modular Rainwater Harvesting System

Made of recycled polypropylene and designed to enable a better quality of life while upholding the socio-economic aspects of ecosystems.

The following are the Advantages of a modular Rainwater Harvesting System :

Made from recycled polypropylene

Modular allows vertical & horizontal expansion

Safe and load bearing – 25 Ton or more per Sq.mt load bearing capacity

Simple and Quick to Install

Low Maintenance Cost

Clog-free and reliable

Effective storage capacity

Very long shelf life

Easy to expand and Easy to relocate the work

Recharge Trenches

Lateral Trench with one or more than one tube wells can be constructed in individual houses, group housing societies and large colonies based on available run - off. The general width of these trenches varies from 1.5 to 3.0 m and the length is about 4 to 12 m depending upon the runoff generated through hourly intensity of rainfall.

Storage System

Another method of Rainwater Harvesting is the storage of Rainwater above the ground, as much as we can and using the water to meet daily needs of individuals. We may adopt the conventional filtration techniques or advance modern filters with the following advantages:

Self-Cleaning

Simple Installation

No Power is required

Works on cohesive force

No consumables required

Fully enclosed and wall mounting

Debris leaves and dirt Particles are removed continuously and flushed out

The filter capacity remains unchanged even with variations in the intensity of rainfall

VEE-Wire Filter Screens

VEE-Wire Filter Screens are fabricated in Pipe Form from Wires. All Welded Wedge Wires Screen is made from 2 elements - outside V–shaped Wire and inside Longitudinal Rods. The V-shaped Wire is spirally wrapped on a cage made of Longitudinal Rods. The intersecting of shaped wire and rod is welded through each other by resistance welding. Due to resistance welding the weld joined is very strong.

Efficient & non-clogging screen.

Anti-corrosive material.

Easy installation.

Vee shaped slots produce a jetting effect to inject recharge water into the aquifer.

Continuous slots give a large percentage of open area.

FRP Filters – Rainwater Harvesting RWH

FRP Filters – Rainwater Harvesting FRP Filter is made of fiberglass. Fiberglass is reinforce plastic that is very hard, compatible and anti-insects. The material allows it for considerable flexibility. The product has a long-lasting life, if maintained and implied properly. Only routine cleaning of the SS Bucket is required.

Furaat Filtration and Recharge pit

Furaat is a modular recharge pit with these salient features:

Quick Installation & Aesthetic look.

Flexibility in volume & depth of well with Good quality precast concrete slabs.

Well can be assembled without using any special devices like a chain pulley as the weight of each slab facilitates working with simple tools.

The size, shape & weight of slabs facilitate well to be transported very easily.

Well can be reused / recycled.

Piezometer – Monitoring the Groundwater

Water level measurements from observation wells are the principal source of information. To monitor the water level at a particular location, either an existing well/borehole is used or a borehole is drilled down to the aquifer that contributes most to the water table. A casing pipe is installed in the borehole to prevent the borehole wall from collapsing. At the level of the aquifer, a highly porous filter is provided at the lower end of the casing pipe. The system basically comprising of a sensor and datalogger is installed in an observation well to monitor the water level variation in it.
