The water-carriage system for waste collection operates by________________?
Show answer Hide answer
Answer: B. requires treatment before disposal
Explanation
The water-carriage system generates substantial volumes of wastewater that necessitate comprehensive treatment before environmental disposal. Transporting human waste through sewer pipes creates a liquid mixture that requires biological and chemical purification plants. Discharging untreated sewage directly into water bodies causes severe ecological damage and widespread public health hazards. The water-carriage system uses water to transport human excreta and domestic waste away from buildings via sewers. Wastewater treatment facilities employ primary, secondary, and tertiary processes to remove pollutants before final effluent discharge. Sanitary engineering standards prioritize safe waste disposal to protect community health and aquatic ecosystems.
While initial setup costs for sewer networks can be high, the primary operational challenge remains treating the collected wastewater. Creating hygienic problems describes the failure of sanitation rather than an inherent functional characteristic of water-carriage systems. Declaring all the above correct is incorrect because options concerning treatment and hygiene differ in validity.
