Why Treat Waste Water ? |
|
Answer» Much of the WATER used for DOMESTIC purposes does not require potable ( suitable for DRINKING) water quality. For instance, water used for flushing toilets or for washing floors, YARDS or roads & gardening does not require to be potable. In a scenario where fresh water is getting increasingly scarce and when enormous volumes of sewage generated in the country are not being treated ,but goes unchecked to pollute fresh water from lakes, rivers and the ground water table, it must be treated. Discharging untreated sewage into any drains other than an underground sewerage system, or into open land , is an offence and invites prosecution under the laws of all Pollution Control Boards in the country. Sewage must necessarily be treated correctly and then re-used/re-cycled for various uses that do not need potable water quality. Recycling/reusing treated sewage can reduce fresh water requirements vary substantially, by almost 50-60%.In a scenario where fresh water availability itself is increasingly in doubt this is critical.
