Problem statement : Those who have money can pay for tankers but it's only promoting tanker mafias and black money now. Some of it pseudo controlled by cops and local politicians. Lake land also being claimed illegally by various parties including corporations. Sewage from industry and housing also joining lakes and rivers.
Govt supply is sketchy and difficult to improve. Need to start independent sources of water and revival of existing bodies.
Solution : Land around water bodies will need to be monitored for encroachments, cleaned up regularly and litigated for, to protect it. Similar stuff happening with aarey forest and metro project encroachment in Mumbai. Floodplain being encroached will make floods and water table levels worse, but it's prime real estate that can be commercialized and sold.
All the lakes and rivers, vrishabhavati especially need to be revived and protected.
Homework : Check out million Wells project and connect with the founder, citizens for Bengaluru group, and read up on history of other revivals and their spearheads. Start water conservation efforts around your societies, basic rainwater harvesting should be in place at least. And yes, stop wasting water ofc.
