The problem is lack of sewage system;these are BASIC infrastructure required; If you build yourself a nice apartment costing 20-40M; without a sewage system;you;ll need two cesspool/soakpit - and they will fill up nearly every week
- and it will probably cost you 60K every month on honey sucker ; Now out of the 150K rent you're getting; 60K is spend on disposing sewage through trucks.
Those sewage trucks go to an abandoned query and discharge it there
It's the same problem - they just dump it near slums and low class people.
Gov has to seriously invest in such horizontal infrastructure;
