Water Resources of the world
Water Resources of the world ,[object Object],[object Object],[object Object],[object Object]
About one-sixth of the world’s people don't  have easy access to safe water Most water resources are owned by  Government and are managed as  publicly owned resources
Use of Water Resources in Pakistan ,[object Object],[object Object],[object Object],Agriculture Industry Public
Principal source of drinking water
GROUND WATER Most of the rural areas and many major cities rely on it, although some cities such as Islamabad, Karachi, Hyderabad etc, get water from a number of other sources
About 80% of Punjab has fresh  Groundwater
In Sindh, less than 30% of  groundwater is fresh
In Khyber Pukhtoonkhwa, increasing  abstraction has resulted in wells  now reaching into saline layers
Balochistan also has saline groundwater
Ground Water cycle Evaporation and transpiration Evaporation Stream Infiltration Water table Infiltration Unconfined aquifer Confined aquifer Lake Well requiring a pump Flowing artesian well Runoff Precipitation Confined Recharge Area Aquifer Less permeable material such as clay Confirming permeable rock layer
Problems Using Groundwater
Water Table Lowering
Depletion
SALTWATER INTRUSION   is the movement of saline  water into fresh water aquifers
Reduced Stream Flow
The drying up of wells  Groundwater in  the sub basin of  Quetta would be exhausted by 2016
In Islamabad, the drop has been  50 feet between 1986 and 2001
In Lahore, the drop has been about 20  feet between 1993 and 2001 .
Rural Water Supply in Pakistan Punjab has the best rural water supply The vast majority of the rural population has either piped water or water from a hand pump or motor  pump.
Only 7 % of the rural population depends  on a dug well or a river, canal or stream.
Sindh is considerably worse: some  24%  of  the  rural population depend on  these    sources
Situation  in  Khyber Pukhtoonkhwa is worse  still  46%
In Balochistan, 72% of the rural population depend on dug well or from a river/canal/stream .
Human Water Needs ,[object Object],[object Object],[object Object]
In the Pakistan each person uses about 188 gallons/day An additional 657 gallons/person/day  are used for irrigation, industrial use
If world’s water supply were 100 liters,  the usable supply would be about 0.5 tsp
US has highest per capita water withdrawal,  followed by Canada, Australia, Russia, Japan
Water Condition in Pakistan
Pakistan has decreased from 5,000 in 1951  to 1000 cubic meter per Annum in 2010
2010 and 2025 have reached 173 million and 267    million respectively
The situation could get  worse in areas where it is already below 1000m 3  per    head

WATER AVAILABILITY IN PAKISTAN
The water Shortage The water shortage in the agriculture sector is another serious issue.  29% for the year 2010 and 33% for 2025.
Today groundwater contributes a merely  48% of the water available
The hike in the cost of electricity in 1990s and the development of  new technologies have led to a considerable increase of diesel pumps whose numbers have grown 6 times over the last 30 years. (SOE 2005)

Sources  of water pollution ,[object Object],[object Object],[object Object],Sources  of water pollution
Municipal Sewage It has been estimated that around 2,000 million gallons of sewage is being discharged to surface water bodies every day in Pakistan (Pak-SCEA 2006)
NCS states that 40% of death  are related to water born diseases
Drinking Water Supply Lines Conditions in Pakistan ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
It is estimated  that 50% Nationally (less than 20% in many  rural areas), with only about 10% of collected sewage is effectively treated
Industrial Water Pollution
Most industries in the country are located in or around major cities and are recognized as key sources of increasing pollution in natural streams, rivers, as well as the Arabian Sea to which the toxic effluents are discharged
Major Industrial Contributors to Water Pollution in Pakistan Petrochemicals, Paper and pulp, Food processing, Sugar, Textile, Cement and fertilizer produce more than 80% of the total industrial effluents
Sugarcane Based Industry ,[object Object],[object Object],[object Object],[object Object]
In Pakistan, only 1% of wastewater is treated by industries before being discharged directly into rivers and drains
Tanneries It may take hundreds or even thousands of years for pollutants such as toxic metals from the tanneries to be flushed out of a contaminated aquifer
In K.P, 80,000 m 3  of industrial effluents containing a very high level of pollutants are discharged every day into the river Kabul
In Karachi, Sindh Industrial Trading Estate (SITE) and Korangi Industrial and Trading Estate (KITE), two of the biggest industrial estates in Pakistan, there is no effluent treatment plant and the waste containing hazardous materials, heavy metals, oil etc. is discharged into rivers.
In Multan, a fertilizer factory discharges its waste untreated to cultivated land causing death of livestock and increasing health risk to humans. (WB-CWRAS Paper 8, 2005)
In Lahore, only 3 out of some 100 industries using hazardous chemicals treat their wastewater. Biological Oxygen Demand (BOD) levels in water courses receiving these wastes are as high as 800mg/l and Mercury levels over 5 mg/l
In Faisalabad, one of the biggest industrial cities, there is little segregation of domestic and industrial wastes
Agriculture Water Pollution
According  NWP, the irrigation network of Pakistan is the largest infrastructural approximately $ 300 billion of investment, 25% to the country's GDP. provides  90 % of food and fiber The remaining 10 % arid.
xcv animal manure  erosion and dust from cultivation, pesticide drift and volatilization This includes runoff and leaching Fertilizers
The study revealed that in Punjab, Sindh and Balochistan and  all drains were carrying saline and sodic waters due to high values of Total Dissolved Solids (TDS) and Residual Sodium Carbonate (RSC) and all of them also had very high values for Chemical Oxygen Demand (COD) and Biological Oxygen Demand(BOD).
The contribution of agricultural drainage to the overall contamination of the water resources exists but is marginal compared to the industrial and domestic pollution. For example, in Sindh, the pollution of water due to irrigation is only 3.21% of the total Pollution (SOE 2005)
