Clean Water and Sanitation

Policy for water reuse

B.S.Abdur Raham Crescent Institute of Science and Technology has a firm policy for water reuse. Water reuse generally denotes the process of capturing wastewater, stormwater, or greywater and treating it as required for a designated beneficial uses such as drinking, or surface or ground water replenishment. The water reuse in the Institute is looked upon in two aspects.

(i) Recylcing of the treated water from the sewage treatment plant for benefial purposes like gardening and toilet flushing
(ii) Harvesting of the Rain water

Some of the key points of the Policy is given below

Main objective : The Institute should be a Zero Dischrage campus

Proper collection and treatment of wastewater generated in the Institute
Regular monitoring for the quality of the treated water
Recycling the treated water for gardeneing and toilet flushing by providing dual plumbing system
Frequent inspection and maintenance of the STP
Rainwater harvesting in all blocks of the Institute
Maintenance of infrastructure facility provided for rain water harvesting
Provision of sufficient storage structures to store rain water
Ensuring that there are minimum wasteage of water in the campus by using advanced monitoring facilities such as sensors
Ensuring the planting of drought tolerant plants for the water conservation
Improving the landscapes of the Institute thereby ensuring a natural water conservation through plants

Policy to harvest the rainwater and reuse

B.S.Abdur Raham Crescent Institute of Science and Technology has a firm policy to harvest the rainwater and reuse it for beneficial purposes.

RAIN WATER HARVESTING STRUCTURES AND UTILIZATION IN THE CAMPUS

The institute has implemented rain water harvesting system in the campus with a strong desire to utilize the rain water at maximum extent
In the forefront to save water, our institute of science and technology has initiated and executed the rainwater harvesting in the campus.
Rainwater harvesting facility is done in all blocks to collect rainwater from the roof of all buildings
The harvested water is diverted to open wells in institute campus, Men’s Hostel and ladies hostel
The placement of rainwater facility within the campus is decided upon by considering the profile of the land so as to drain the maximum amount of water collected with ease
In the buildings, sufficient plumbing connections are provided to trap the rain water from the roof tops
Underground connections are ensured to connect the collected water from the roof top to the rainwater recharge pit
It was also ensured that the rainwater harvesting structures are constructed as per the norms. The recharge pit provided to collect the rain water is series of filter bed
This initiative took shape when the institute faced shortage of water during summer. Cost of buying water was becoming a financial burden. The only alternative to the water crisis was to use the available water more effectively
The features of the recharge pit are described below
A mesh is provided at the inlets of rain water pipes so that solid waste/debris is prevented. B.S.Abdur Rahman Crescent Institute of Science and Technology has taken initiatives to install rain water harvesting pits in the campus from entering the pit system.
The recharge pits are of size 2m x 2m x 2m is excavated
The recharge pit comprises different set of filter media. The filter media comprises of thick layers of boulders at the bottom followed by layers of gravels and coarse sand.
This enables the filtration of water and also prevents the deposition of silt on the recharge pit.
Access Manhole frames and covers are provided.

The rain water is also stored in Underground sumps of Life Science block, Mechanical Science Block and New Staff Quarters.

Rainwater harvesting facility is done in all blocks to collect rain water from the terrace. The
details are listed below.
