What is the integrative purpose of an urban water recycling plan in geography?

Correct answer: Reducing water demand waste management resource conservation and health safety

The direct answer is B. An urban water recycling plan is integrative because it connects water demand, treatment of waste, conservation of resources, public health, and city planning. Used water can be treated and reused for suitable purposes such as gardening, flushing, or some industrial activities. This reduces the need to take fresh water and also prevents untreated waste from polluting rivers or groundwater. Option B is correct because it includes all these linked aims. Option A is wrong because changing water colour has no meaningful planning or conservation purpose. Option C is wrong because counting pipes is only a small technical activity, not the complete geographical objective. Option D is wrong because constructing tanks alone does not ensure treatment, reuse, conservation, or health safety. The plan supports sustainable urban development: meeting present needs while protecting future resources. Remember: recycling means reduce demand, manage waste, save resources, and protect health.
