El Paso, Texas
Alvine Aquatics’ engineering professionals designed the life support systems for the 45,000-square-foot outdoor sea lion exhibit. The 90,000-gallon tank is home to sea lions and is part of the North American exhibit. With its rock formations, plants and landscaping, the exhibit interprets the environment of the Sonoran Sea, the closest large body of water to El Paso.
Public areas of the exhibit include an underwater observation area, numerous above ground viewing areas and a natural 200 seat amphitheater. The tank and surrounding areas were carefully designed to allow the sea lions sufficient space to maintain the same activity levels and swimming patterns that they would in the sea. Because of the remote location of the support building, pumps for the system were carefully selected to solve the challenge posed by the distance from the exhibit.
The Alvine Aquatics engineering team also completed schematic design for a future aquarium exhibit of nearly 30,000 gallons.
Major Program Spaces

Water Treatment Systems
- Piping and pumping systems, as well as redundant pumping
- Sand filtration
- Water temperature control for cooling
- Ozone injection systems for disinfection
- Ozone leak detection and exhaust system for safety
- Foam fractionation for reduction of micro-particulates using ozone or air
- Ultraviolet disinfection for algae control
- Incoming city water treatment with reverse osmosis and activated carbon strips with residual ozone
- Saltwater tank reclaim backwash for responsible conservation of resources through recycling water and to minimize discharge to city sewer
- Deck wash-down systems for cooling concrete deck in hot weather
- Active carbon downstream of degas chamber to strip away any residual ozone
