INTRODUCTION
For the drinking water of the capital Jaipur, 80 percent water is purified from the Bisalpur Water Supply and the remaining 20 percent water is obtained from the ground through Tube Wells & Handpumps. However, it is worrying that the river is the lifeline of 60% of the people therefore, to get clean drinking water households depend on RO (Reverse Osmosis) purification or Bottled Water. Water is a natural resource, and it supports to keep balance of nature. Both blessings and curses are applied to scientific discoveries. Scientists developed RO technology to provide pure and clean water, but its misuse is causing a water disaster Only 0.5% of fresh water on Earth is drinkable, but climate change is threatening that supply. Water scarcity will put a burden on the food supply Lack of access to clean water is a major health concern in poor nations, where more than 2 billion people live without basic sanitation and millions die each year from water borne infections.The capacity of RO is measured in litres. For a 4 Member Family 15 litres of RO is sufficient . But to produce 15 litres of RO treated water 50 litres of water is used left over, 35 litres of water gets waste.
The Waste Water of RO
So this is the major problem to our lives . Treated water and waste water is 30%-70%. In Jaipur there is 4.5lac. housesand almostall have RO. To combat this problem human should start sustain water use and focus on waste water management. The waste water from the RO is used for a variety of different daily tasks such as washing clothing, cleaning kitchenware , the house, watering plants and gardens.
1. Water sources in the homes of RO users
EWS, LIG, MIG, and HIG households were chosen as responders, and their information is mentioned :-
- EWS – Economically Weaker Section
- LIG – Low Income Group
- MIG – Middle Income Group
- HIG – Highest Income Group
Fig. 1 shows the data in which there are two water sources for water supply in the selected respondents homes. Municipal water supply and personal submersible. Are available to all types of residences,although HIG, LIG and MIG household have personal submersible for water supply as the above Figure shows, which contains the number of different types of houses and their water sources.
Both house hold water consumption and water sources were evaluated in Fig. 2. All types of house holds use water for drinking, bathing, cooking, washing clothes and sanitation. Apart from this, the requirement of water depends on the income, education, job, etc. of the families. In economically stronger families, machines are used for gardening, cleaning vehicles, watering trees and washing clothes and utensils, which consumes more water.
The waste water cannot be used in as hing Because this is hard water but it can be used in moping.Andalsotoirrigateplantsbydripsystemin which water Falls dropby drop near the roots of plant. And it is not necessary that the water is hard or not. The waste water cannot can be also used where RO water supply is done this Waste water. The waste water cannot be used in as hing Because this is hard water but it can be used in moping and also to irrigate plants by drip system in which water Falls dropby drop near the roots of plant. And it is not necessary that the water is hard or not. The waste water cannot can be also used where RO water supply is done this Waste water
2. Solution
In which houses RO waste water is reused?
The decision to reuse RO waste water is dependent on the type of house.According to the data shown in Fig.6, just 38% EWS household use waste water, while 62% do not. Similarly, just 29% of LIG house holds utilize waste water, while 71% do not. 55% of MIG houses have RO waste water reuse while 45% of houses do not .Where in82% HIG houses do not use RO waste water, only 18% houses reuse RO waste water. Can be supplied again to RO and then this water can be again RO treated water.
- RO waste water can be collected in a bucket or large bottle and reuse.
- RO waste water is mostly used in coolers.This may also because this research was done in summer time fig.6.
- In the same sequence, RO waste water is used for washing clothes fig.6.
- After this,the water coming out of RO is used for cleaning vehicles, house etc.The number of which is seen in the picture fig.6.
- Government should set policies for recommend to encourage the reuse of wastewater for urban irrigation through out the country fig 3.
- Government should make pipelines to conserve RO waste water. Approx in each house 60 litres of RO treated water produces but to produce 140 litres of water supply to make RO treated.
3. Recommendations and Suggestions
- Reusing RO reject water can lead to water conservation, cost savings, reduced environmental impact, and improved overall water management practices.
- It’s a sustainable approach that benefits both organizations and the environment by making more efficient use of water resources and reducing the negative consequences associated with reject water disposal.
- Engaging with the local community and demonstrating responsible water management practices, including reuse of reject water,can garner support and good will from residents and stakeholders.
- RO manufacturing companies should encourage people to reuse RO rejected water in advertisements. People should be made aware that RO should not be used if it is not necessary.
