(2) True: Used water which is rich in lather, mixed with oil, dirt, etc can be referred to as wastewater.
(3) True: Wastewater treatment plants are used to convert waste water into usable water through various physical, chemical, and biological processes, which remove physical, chemical and biological matter that contaminates the wastewater.
(4) False: Where underground sewerage systems and refuse disposal systems are not available, the low-cost onsite sanitation system can be adopted. To improve sanitation, low-cost onsite sewage disposal systems are being encouraged. Examples are septic tanks, chemical toilets, composting pits.
