I am afraid that I don't have any information about NGO's in Pakistan, however WaterAid, who I have been involved with for many years operate in Pakistan through local NGOs. They may be a route.
in terms of technology that really does depend on what the issues are and the availability of support for them so that they are locally sustainable. It also depends on the scale of the problem and locality eg village or urban.
I am sure that if you have any specific tech queries I or others will try our best to provide answers on here. Good Luck.
