Summary
Martinville Oxidation Pond Wastewater Treatment Plant in Louisiana is a vital facility owned by the local government that plays a crucial role in managing the region's wastewater. Designed by Domingue Szabo and Associates, this plant is regulated and permitted by the Louisiana Department of Transportation and Development. Situated on the Cypress Island Coulee, this plant has a low hazard potential and is in fair condition, with a very high risk ranking.
Completed in 1970, this Earth-type dam has a height of 15 feet and a storage capacity of 382 acre-feet. With a controlled spillway and vertical lift outlet gates, it serves its primary purpose of water treatment efficiently. Despite being inspected in 2012 and meeting guidelines, the plant faces a very high risk due to its age and structural modifications in 1994. This facility, located in St. Martinville, plays a critical role in protecting water resources and the environment in the area.
For water resource and climate enthusiasts, the St. Martinville Oxidation Pond Wastewater Treatment Plant offers a fascinating insight into the infrastructure that supports sustainable water management. With its strategic location, efficient design, and regulatory compliance, this facility stands as a testament to the importance of wastewater treatment in safeguarding public health and the environment. As it continues to operate under the supervision of the local government and state regulatory agencies, it remains a key player in maintaining the ecological balance in St. Martin, Louisiana.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
