Big Grass Expands Decorative Ong® Rainwater Harvesting Collection

Small Ong jar by Big Grass 2Big Grass, the largest provider of sustainable home and garden décor in Texas, has expanded its Ong® jar rainwater harvesting collection to meet the growing demand for water conservation solutions nationwide.

“As regulations and incentives to conserve water increase, customers are seeking harvesting options that are both functional and aesthetically appealing,” said John Hanesworth, co-owner of Big Grass. “The Ong® jar collection offers attractive alternatives to conventional plastic and metal collection vessels to harvest water from rainfall or AC condensation.”

Big Grass is rolling out its new tallOng®, a 240-gallon vessel with a narrow profile suitable for tight spaces. Big Grass will also soon launch a new version of its 115-gallon Mini Ong® offering customers, especially newcomers to rainwater harvesting, a stylish catchment option with a small footprint.

The two additions complement Big Grass’ existing 160- and 450-gallon Ong® jars. Ong® jars are designed to collect rainwater from roof sections and condensation from air conditioning units, conserving and replacing groundwater and easing demand on municipal storm water systems. All Ong® jars can be integrated into larger catchment systems.

Ong® jars by Big Grass are handmade in Thailand from durable cement. Large-volume jars of various forms and materials have been used for centuries in Southeast Asia to collect rainwater in times of drought. They remain a staple of daily life in many rural communities and are still used for household water collection and drinking water.

Big Grass works directly with producers in Thailand and is the only U.S. source for Ong® jars. In 2014, the U.S. Patent and Trademark Office granted Big Grass’s request to register the “Ong” mark.

Since 2005, Big Grass has sold hundreds of Ong® jars in drought-prone South Texas and other parts of the country. Big Grass custom stains and seals the Ong® jars, and each vessel comes with standard hose faucet fittings, drain plugs and galvanized metal lids. Metal filter baskets are available to prevent entry of leaf debris and to discourage mosquito growth.

In recent months, homeowners associations have invited Big Grass to display the jars at member events.

“Ong® jars are popular among both retail customers and landscape designers,” Hanesworth said. “In addition to their ease of use, they add long-lasting style to outdoor spaces unlike many plastic containers that become brittle with prolonged exposure to sunlight, or metal containers that are difficult to conceal and can eventually rust.”
