NOTICE for PUBLIC COMMENT
PRASA Adjuntas (Garzas) Water Treatment Plant
Adjuntas, Puerto Rico
SUMMARY
The Puerto Rico Aqueduct and Sewer Authority (PRASA) has
applied for renewal of its National Pollutant Discharge Elimination System
(NPDES) permit for the Adjuntas (Garzas) Water Treatment Plant (WTP) in
Adjuntas.
The Adjuntas (Garzas) Treatment Plant (WTP) is a filtration plant that
treats water from the Las Vacas River to provide clean drinking water to
various wards in the Municipality of Adjuntas. Wastewater from the plant
discharges to an unnamed creek tributary of the Cidra River.
The NPDES permit ensures that the amount of discharge and the amount
of contaminants in the discharge remains below levels that are safe for
the environment and public health consumption.

PRASA ADJUNTAS FLOW SCHEMATIC
This diagram summarizes the WTP process.
This is based on a scenario where there is
maximum water flowing in the treatment
plant. The actual amounts of water may be
less.
DRAFT PERMIT CONDITIONS
The permit establishes numeric water quality effluent limitations for several pollutants, including pH, dissolved oxygen,
temperature, taste and odor, color, turbidity sulfates, total ammonia, suspended solids, and metals.
The permit limits the WTP's numeric flow effluent pursuant to Puerto Rico Environmental Quality Board (PREQB) and
other conditions.
Under NPDES the permit specifies requirements for recording and reporting monitoring results of the numeric effluent
limitations described above.
