7.0+–+CONCLUSION

Currently world is looking for new energy alternative and green solution.People are going for new renewable energy technology.New technologies always find difficulty of acceptance.Drain water is one area ,where lot of awareness is required.People are not familiar with the use of drain water energy capability.Governments are taking initiatives and industries are supporting new technologies.During brainstroming stage ,we had considered drain water power system implemetation in residentail housing levele and power generation facility at the drain water dumping station.But for that system will be complex and lot of governement approvals will be required and for whole city drain water sysytem ,you need hugh investment.Due to that reason ,we consider to apply this system to high rise building considering benefit of height and gravitational force.For the individual household drain power heat recovery sysytem is already available which is very helpful to reduce energy bill of individual household.Drain water power technology is new concept, it's installation cost is more.But if you are considering for new construction,it may be cost-effective as you can design you building considering this sysytem.All of this can be possible, if governments come forward and announce incentive for property owner/developer.While for existing building retrofit cost will be more and you need lot of structural changes. In existing building we can use in line turbine system.
