Wastewater Treatment practices in Pakistan:

There are very few cities in Pakistan which has WWT plants but most of them discharge their wastewater without treatment. Islamabad, Karachi, Lahore, Multan and few other large cities have various treatment plants such as CW, secondary treatment, and tertiary treatment. Instead of having treatment plants, only 8% of WW is treated before disposal. Framers in Pakistan use this WW for irrigation as it contains nutrients, reliable supply and has a great impact on lands and agricultural sector but this WW changes the chemical and physical properties of soil, contaminate food and cause harmful effect on human health. <a href="https://medium.com/@sabashakoor845/wastewater-treatment-practices-in-pakistan-4f754ae14144">Website</a>
