Fiberglass Tanks Meet Rising Standards for Storm Water Management

With increased incidents of flooding caused by extreme weather, cities across North America are developing more rigorous storm water management standards for new construction. When TAHK Projects Ltd., a gas and oil field construction company, planned a 10,440-sq-ft pipe manufacturing warehouse in Edmonton, AB, Canada, the engineer at Design Works Eng. was tasked with creating specifications that fit Edmonton’s new storm water requirements.

A key consideration was to determine whether an aboveground or an underground system best fit the 96,000-sq-ft site.

“The higher storm water management standards mean that you can’t always manage storm water runoff on the surface of a property, and on this property, underground was the best answer,” said Abdullah Rabi, vice president of civil engineering at Design Works Eng.

Rabi looked at all underground tank possibilities for the site, including ZCL | Xerxes, with whom he had worked before.

“As an engineer, I know that as soon as we are retained in design projects, the sooner we involve the companies that provide storage tanks in the process, the better chance I have of giving the client the best recommendation based on both product and cost,” Rabi said. “Getting ZCL | Xerxes involved early helped me see that we could save both time and space at this site by using two of their available standard-sized tanks instead of a single customized tank.”

The ZCL | Xerxes sales team proposed two, single-wall 24,000-gal fiber- glass tanks rather than custom manufacturing a single tank large enough to meet the specified storm water capacity. Recommending fiberglass tanks offered several advantages, according to the project’s engineer.

“Fiberglass tanks are easier to transport to the site and easier to install than concrete, especially for a project requiring a large-capacity system like this one,” Rabi said. “And the two tanks side-by-side rather than one long tank, was a better scenario for the property.”

Rabi said fiberglass may be more expensive if one looks solely at the material cost.

“But when you consider all factors, it makes fiberglass a good cost-savings choice all around,” he said.

Another significant factor that led Rabi to present the solution to Keller Construction, the project’s general contractor, was the collaboration he received from the ZCL | Xerxes team.

The tanks looked best “from both a construction method and a timing point of view,” said Rabi. “Beyond that, all the information I needed to pres- ent this option was readily available, and they were willing to work with us for a quick turnaround to get the project moving.”

Installing the ZCL | Xerxes 10-ft-diameter storm water detention tanks under the site’s parking lot provided:

  • Watertight tanks that meet rigorous storm water management standards;
  • Underground tanks that are readily available and save space and project time;
  • Corrosion-resistant fiberglass tanks that offer easy delivery and installation; and
  • Large-capacity tanks that provide a long-term, cost-saving solution.

ZCL | Xerxes tanks can be installed as single tanks or multiple connected tanks, depending on site and storm water requirements.
