In order to improve urban water safety and water environment quality,the implementation of rain and pollution diversion transformation is a crucial measure.This paper takes the rain and pollution di-version reconstruction project in Lutian town,Conghua district as an example,and puts forward feasible solutions.Key construction techniques include:distribution pipe preparation,pipeline repair,pipeline design,laying,pipeline foundation backfill and pavement backfill.Through the implementation of the rain pollution separation system,not only can effectively control and reduce the mixing of rainwater and sewage in the drainage process,but also improve the efficiency of sewage treatment and reduce environmental pollution.The establishment of the rain and pollution diversion system is a key component of the construction of sponge cities,which helps to collect and use rainwater,while enhancing the resistance of cities to natural disasters by increasing the water permeability of the urban surface.
