Introduction
There is many advantages from having a wastewater Collection system …….. Conservation of environment, reduce pollution of groundwater
Tubas city dose not have infrastructure for the wastewater ………….. They get rid the wastewater by using cesspits
The solution is construction of wastewater collection network accompanied with wastewater treatment plant
