Access to safe drinking water is inadequate in Pakistan. Moreover public health authorities have not been able to reduce the frequency of waterborne diseases resulting from microbial disinfection. Empirical evidence shows that people with sustainable access to quality drinking water is barely 25% (Nils, 2005). According to the Pakistan Council of Research and Water Resources (PCRWR), water related diseases form 40% of all reported illnesses. Further it is projected that in Pakistan diarrheal diseases alone cause the death of 200,000 children each year. Following these estimations it is noted that 600 rural and urban poor suffer from different ailments and water allied diseases daily due to bad quality/contaminated water. On the contrary drinking water quality is deteriorating persistently as a result of biological contamination i.e. human waste. On the contrary the problem of water contamination is further exacerbated by chemical pollutants from industries and agricultural inputs. The centralized distribution system for drinking water through pipes and the drainage system (sewerage lines) lie very close to each other hence any damage to either of the two results into water flowing from one into the other consequentially contaminating the water. Open drains in close vicinity of the drinking water pipelines also result in contamination of water and cause many serious water borne diseases. In Pakistan 45% of infant deaths are attributed to diarrhea and 60% to overall infectious waterborne diseases. The Public Health System is over burdened with water borne diseases such as cholera, diarrhea, dysentery and typhoid hence causing considerable economic losses. In this context estimates show that only diarrheal diseases are costing the country Rs. 55 to 84 billion annually.
