Water Supply and Sources

Water could be a major component in successful production of greenhouse plants. Associate in nursing adequate water supply is required for irrigation, phase change cooling, chemical application, growing media preparation and cleanup.

The target of the cognitive process and maintenance of sources of water supply strategies is:

1) The water sources should be ready to supply water that is safe to drink when treatment.

2)  The water sources ought to be perennial and will guarantee property yield.

3) The quality of water mustn't be allowed to degenerate.

4) In that location should be lost or no disturbance in water supply systems due to depletion of water sources.

5) There should be least potential expenditure on the repair and maintenance of the water sources.

6) Proper record of the water sources should be unbroken so their time to time Performance might be recognized.

7) A organized long-range program of supply scrutiny and observance ought to be inserted to spot issues so a daily program of preventive care will guarantee reliableness and persistence.

8) Survey maps shall be received or ready for all potential authors of water like rivers, artificial lakes, lakes and groundwater.


Sources of Water Supply:

• Natural Source
• Surface Water
• Ground Water
• Municipal water

Setting up of Sewage Treatment Plants to Clean Yamuna River

Untreated sewage drains into river Yamuna flowing through Delhi due to which the Yamuna water gets contaminated.

According to Central Pollution Control Board (CPCB), CPCB has initiated monitoring and performance evaluation of Sewage Treatment Plants of Delhi. Waste Water Generation in Delhi has been assessed as 3800 MLD and the Waste Water Treatment capacity developed so far is 3059.48 MLD comprising 40 STPs, leaving a gap of 740.52 MLD in the treatment capacity. The STP at Coronation Pillar I (old) of 45.4 MLD has not been included in the assessment due to its closure.

Out of 40 STPs, 32 STPs (2643.35 MLD) are operational, 07 STPs (325.33 MLD) are non-operational and 01 STP of capacity 90.8 MLD is under construction. There is gap of about 36.53 % as far as development of operational sewage treatment capacity is concerned. The capacity of treatment facilities is only 63.46 % as against the quantity of waste water (1941.67 MLD) reaching to STPs. The operation of these STPs is being maintained by Delhi Jal Board. According to the Delhi Jal Board (DJB), the major drains in Delhi receive untreated waste water flows from mainly two sources (i) from the adjoining state Haryana through Badshahpur drain, Gurgaon, Panipat and Sonipat drains and (ii) from the sub drains emanating from the unsewered areas of Delhi.

Delhi has undertaken a mega project to tap all such sub drains carrying untreated waste water flows into the major drains, directions have been issued by Hon'ble NGT to Haryana state to establish its waste water treatment plants to ensure that only treated effluent flows into the drains out-falling into river Yamuna. 

Back to Basics in Water Treatment

Water is the most precious natural resource available on the earth. It is our life’s source. Humans can live without food for many days but hardly can survive more than 3 days without water. The resource, in natural form, is quite pure, but the amount of contamination prevalent these days makes it unsafe to drink. The contamination is caused by various chemicals, pollutants, and other waste products, which are emptied in the water resources such as a lakes and rivers. This calls for a cleansing and treatment of water before it can be utilized again.

Water Treatment Plants are the ideal way to restore the water properties back to its natural form. There are many different applications of the plants on the basis of the requirements. Some focus on cleansing the impurities while others are meant to provide higher levels of oxygen-rich contents.

Packaged water plants are installed to reduce the amount of chemical oxygen demand from the water. Normally, lakes and reservoirs contain significant levels of oxidizable inorganic materials, hence, water plants can help to remove the solid waste. These plants employ a different level of processing such as precipitation, reverse osmosis, etc.

Ozone plants are used to disinfect the water. The most common application of such plants is seen in treating the pool water, where ozone is used for purifying the water.

Waste treatment plants work on the principle of cleansing the waste products emitted by industries and homes. The plants work for the purpose of recycling the water and removing any waste products collected in the water.

Water Treatment Plants are a great solution to cope up with the ever-growing demands of the water. While, the plants may not retain the natural properties of the water, but it is still a viable option to treat the impure water. With the amount of industrialization in demand, it holds no thought a large amount of population is going to be dependent on these plants to meet the daily requirements of water for drinking and other purposes. 

Water Treatment Plants are Shut in New Delhi

As Delhi Chief Minister Arvind Kejriwal put it, the city is facing an 'unprecedented water crisis'. 60 per cent of Delhi's water supply has been hit due to Jat quota protest in Haryana, which has led to disruption of water supply from the Munak Canal. This has caused closure of seven out of nine waste water treatment plants in the national capital.

Left with no option, the Delhi government has started rationing water and announced that all government schools will remain closed on Monday. On Sunday, water reservoirs in Delhi ran out of stock as treatment plants were shut down due to unavailability of water from Munak canal.

On Sunday, several parts Delhi faced water problems. Residents had to call up private tankers.

The government has now asked Delhiites to be prepared for the next few days and conserve water. "No water is available now. If something is not done right away, Delhi will face an unmanageable crisis," Deputy Chief minister Manish Sisodia said, adding he has directed all schools to be closed on Monday due to water crisis DJB said their teams have managed to supply water in small quantities to most areas on Sunday evening. It will try to do so on Monday morning as well, but if the problem persists the city will face an unprecedented crisis.

So water and waste water treatment plants are very necessary for day today life we all know. It's a matter of caring for our environment and for our own health. There are a lot of good reasons also like Fisheries, Wildlife Habitats and etc why keeping our water clean is an important priority. If wastewater is not properly treated, or waste water treatment plants are shut then the environment and human health can be negatively impacted.

Water Treatment Plant to be Set Up

SHIMLA: Chief minister Virbhadra Singh on Wednesday laid the foundation stone of water treatment plant at Lambloo that would cater to 43 villages of the area. The plant will come up at a cost of Rs 1.54 crore.

The chief minister also laid the foundation stones of drinking water supply scheme at Jhaniara and a shelter home for the homeless at Hamirpur. Taking a dig at former chief minister and BJP leader Prem Kumar Dhumal, Virbhadra alleged that Dhumals, in connivance with a Union leader were hatching a conspiracy against him and trying to implicate him in false cases. tnn

He also raised the Himachal Pradesh Cricket Association (HPCA) controversy saying that the land lease was not a big issue, but the error occurred when the HPCA was converted into a company instead of registering the same under the cooperative Act.
