The overall goal of "Six Rivers" trilogy is to eliminate cities by 2023.

The overall goal of "three steps" of "six-water treatment" refers to basically eliminating urban waterlogging points, sewage outlets and sewage blank areas in built-up areas by 2023. Six water treatment refers to sewage treatment, water supply guarantee, drainage, flood control, water saving and marine optimization.

All control sections are up to standard, concentrate on key breakthroughs, and the system planning will be steadily promoted to eliminate black and odorous water bodies in urban areas and counties in 2023, and concentrate on promoting "three coverage" and "two transformations" (that is, improving the coverage rate and efficiency of urban domestic sewage treatment and the coverage rate of centralized sewage collection and treatment facilities in established towns). )

The overall goal of the "Six Waters * * *" campaign proposes that by 2026, urban and rural sewage treatment facilities will be basically covered. Around this goal, we should pay close attention to the outstanding problems and weak links in domestic sewage treatment, take measures and implement treatment measures simultaneously.
