2. Filtration of sewage removes the floating debris, and sedimentation removes grit (small pebbles, and soil particles) from the sewage.
3. All the solid particles settle down to form primary sludge, and supernatant forms the effluent, which is taken from, the primary sludge tank and transferred to another tank for secondary treatment, where the wastewater is treated with microorganisms for biological treatment.

Final answer: The system of a network of pipes used for taking away wastewater from homes or public buildings to the treatment plant is known as sewerage.
