According to a survey of the Superintendencia de Servicios Públicos Domiciliarios (SSPD) or Superintendency for Residential Public Services in 2004, 72% of the users had water of potable quality.
For example, only 73% of those receiving public services receive water of potable quality and in 2006 only 25% of the wastewater generated in the country underwent any kind of treatment.
The reused water can guard against water shortages caused by droughts or increased potable-water usage, especially by supplying industry with high quality water for non-potable uses.
Simulation results indicate that both wells produce water requiring additional treatment to maintain potable quality in winter when groundwater withdrawals are reduced because less water is derived from parts of the aquifer that contain water requiring less treatment.
Surface water treatment with electrocoagulation can produce high quality water, for either potable or industrial use.
Simply put, if you want to drink very clean water, direct potable reuse will likely provide higher quality water than many drinking water plants currently produce now.
The treated water is almost of potable quality (645 mg/l TDS) except for high COD (935 mg/l).
As a result of this situation, both public-supply wells produce water requiring additional treatment to maintain potable quality in the winter when pumping rates are lower.
Clean water that conformed to World Health Organization (WHO) guidelines on Potable Quality was reclaimed.
