Providing Onsite Septic Storage
Secure storage of corrosive wastewater is essential in both onsite and municipal applications. The cylindrical tanks’ smooth, rounded walls make them easy to clean because they avoid trapped debris common with tanks that have corners. Since fiberglass is inherently corrosion-resistant, Xerxes tanks don’t need added protection to guard against corrosion. This results in ongoing cost savings because they don’t require the regular inspection and maintenance tanks of other materials need.

Success Stories
Mining - Alaska, US
Helping protect water source for an Indigenous community
A wastewater tank that traveled nearly 2,000 miles – by air, sea and road – to an Arctic Circle zinc mine is a prime example of how easy it is to ship and install Xerxes tanks. It’s also proof that our highly engineered tanks can be installed in the most extreme climates. While an unusual project – installed in an aboveground shipping container because the permafrost precludes underground installation – it also shows our tank’s adaptability. The tank is part of the mine’s treatment system, with strict guidelines so wastewater discharge doesn’t endanger a nearby village. Beyond needing an easy-to-transport tank, the land and mine owners, the Iñupiat people of northwest Alaska, required a customizable tank resistant to harmful chemicals. The majority of the mine’s workforce are Indigenous people. This installation is a good example of how adaptable our fiberglass tanks are.
RV Park - Oregon, US
Fiberglass tank provides
long-term water conservation
When the owners of an RV park in Oregon upgraded their septic system, they wanted to come up with a solution that added to their energy-generating solar panels. With a maximum 5,000-gallon draw of well water per day, they needed another water source for irrigation. The park owner installed a patented natural wastewater system, using willow and poplar tree roots and bacteria to break down and neutralize pollutants, so that the treated wastewater could be reused for landscaping. As part of this innovative system, this project needed a tank that could be easily customized and installed in a tight excavation footprint. Xerxes provided a three-compartment 25,000-gallon tank, with baffles separating the chambers used for each phase of the wastewater treatment process. Our tank was the perfect underground storage option for this innovative wastewater system that created long-term conservation of both water and energy.
