Wastewater drain routes and leakage prevention measures For efficient wastewater treatment, it is critical to control wastewater inflows. Wastewater should enter treatment equipment through different routes isolated from each other. Employ safe constructions to prevent piping leaks. Pipes and valves connected to plating facilities and related equipment should be exposed to enable easy inspection and maintenance. Inspect and control these facilities thoroughly to prevent leakage.
Water supply requires special attention.
The sump pits and separation baths, as well as the floors of those that hold water for a long period of time, should be coated with waterproof mortar or solvent-resistant resin mortar to prevent permeation. Side ditches should be produced as shown in Figs. Design side ditches to enable smooth wastewater inflow. Sump pits should be kept empty as spare baths in case of emergency. 1-6 Typical Sump Pit and Surrounding Construction Fig.
