Darco Inc

Water tank design and fabrication has been our core business since 1985. We provide manufacturing services at 5 locations across the country. Darco currently offers the largest direct bury fiberglass water storage tank made in the United States at 80,000 gallons. We specialize in tanks specifically designed for fire service meeting NFPA standards for both rural fire cisterns and commercial fire sprinklers reservoirs.

As local, regional and state governments and planning authorities adopt regulatory and policy positions that encourage, incentivize, and require more sustainable and efficient structures, on-site water management is becoming an increasingly attractive and cost-effective means to achieve these goals.

This section contains two PDFs: First our Installation Brief which is a condensed version of the full installation manual, and second the complete Darco Underground Fiberglass Tank Installation Manual. The Installation Brief will help you understand how to install and backfill cistern tanks to meet Darco warranty standards and thereby accurately estimate the costs involved in the installation process.

Because all underground tank application are to some degree unique, we get calls from people who know they need a tank, but are unfamiliar with all the possible variables to be considered for their tank installation. To help, below is a list of questions we routinely ask our customers so they can better understand what they may need or want.

I've been installing tanks for other companies and a number of other suppliers since 1989. Thank you Sandra. This is exactly what I need for budgeting purposes and will keep you posted as the project moves forward. I have enjoyed working with you as well, you are a "shining star" in your industry, it was a pleasure.
