The City of Sulphur is committed to the maintenance and upgrading of our system to continue to provide safe drinking water for all citizens. The City’s Water Treatment Facilities are managed by a Supervisor and Compliance Officer who oversees (4) operators and (3) laborers. The Water Plant personnel are responsible for maintaining and following all procedures dictated by the governing bodies (EPA, DEQ and Louisiana Department of Health) who regulates all treatment facilities in Louisiana. The City of Sulphur water is provided by the Chicot Aquifer and is treated by two different Water Treatment Facilities.

Verdine Water Treatment Facility

The Verdine Water Plant was built in 1993 and provides water to the west side of the City.  The Verdine Water Plant utilizes one (1) 2-million-gallon ground storage tank and (1) 500,000-gallon elevated storage tank. Verdine Water Plant’s average monthly water production is approximately 43,500,000 gallons. The Verdine Water Plant recently went through upgrades to the filter system and third phase of improvements is in development with the City Engineer.

North (Gradney) Water Treatment Facility

The North Water Plant was built in 1980 and provides water to the east side of the City. The North water Plant utilizes two (2) 500,000-gallon ground storage tanks and (2) 500,000-gallon elevated storage tanks. North Water Plant’s average monthly water production is approximately 63,000,000 gallons.

Each facility is equipped with three (3) 2000 gallons per minute service pumps and a 2500 gallons per minute fire pump. Also, the facilities are equipped with telemetry systems allowing the remote access to equipment status and tank levels. In the event of power outages, each treatment facility is equipped with an 800-kW standby generator.

Louisiana Department of Health is the governing body that oversees that all regulations are being followed on a daily and monthly basis.  The City of Sulphur has 40 predefining sampling stations throughout the City. LDH will randomly select about (10) ten sampling sites to test bimonthly. These bimonthly tests check for coliform bacteria and chlorine levels.

Boil Advisories are recommended by the LDH when the following happens: water system’s pressure drops below 20psi, the disinfection process fails, or an event that occurs that allows water of questionable quality (cross connection contamination, major line breaks, etc.) to enter the distribution system. When any of the events mentioned above occur the City of Sulphur issues a declaration boil advisory form to the LDH and sends out a Press Release via Regroup Notification System, City Facebook, City website, and to media outlets. Once the issue is repaired, the required number of samples that LDH will require is taken and submitted for testing. This can take approximately 48 to 72 hours to receive results unless it falls on a Friday, weekend, or holiday then it will take longer. Once LDH notifies the City that all samples have passed, the City will notify via all measures taken before that the Boil Advisory has been lifted.
