3 Years UV Operation in Texas

Horizon Regional Municipal Utility District (Horizon City, Texas)
The Horizon Regional Municipal Utility District is located in El Paso County, the most western county in Texas. The city is home to a rapidly growing population of 19,000 people, up from 5000 at the 2000 Census.

The wastewater is discharged through the Neptune Benson UV into the Mesa Spur Drain, which then eventually flows into the Rio Grande River.  The system is comprised of 4 UV chambers each containing efficient 800 watt lamps, configured in a non-symmetric arrangement. Each chamber has an automatic wiper that keeps the optical path free from fouling, and the water leaves the UV chamber thru the exit nozzle that has a chamfer designed to avoid high velocities that are typically associated with a 90 degree elbow.

Commenting on the UV performance, Adrian Rosas, P.E. of TRE & Associates, LLC, the Design Engineer for the project stated:

“We have been very pleased with the performance of the ETS-UV system by Neptune Benson.  The system has been in use for almost 3 years with no component failures.  Everything works extremely well.”

These units incorporate a number of valuable features that were critical for the success of the project.  These features included the low headloss characteristics through the units that allowed installation in an existing piping system, the enclosed system meant the units could be installed at ground level while preserving the total dynamic head in the piping, and the unique chamber design provides very efficient UV dosage.  Automatic wipers are great to keep the quartz sleeves clean.  The access hatch allows the operators to easily take care of any needed maintenance.  The operators like it very much.”

Commenting on the installation, ETS-UV President Jon McClean added:

“These systems use advanced power efficient 800 watt amalgam lamps.  It is pleasing to see the operators finding value in the features of our Neptune Benson UV systems.  This family of UV systems has been validated in accordance with the NWRI (2012) guidelines and we see a lot of interest now from water reclamation facilities that want to use an advanced closed vessel system”
