Or to take tertiary treated effluent and make it recharge groundwater through layers of soil pulling in contaminants all over again? Continue reading
A look at the utility invoices sent out to consumers in many cities makes it clear why water is an under-valued resource. The unclear language and confusing acronyms do nothing to educate or inform.
