WATER MANAGEMENT

Each small block is individually irrigated
based on the grapes' needs

The SeVein region, where XL Vineyard is located, has water rights specifically identified to the area and our property. SeVein taps water more than 1,000 feet below the surface filtered for decades through multiple layers of basalt and replenished from the Blue Mountain snowfall. No expense was spared in developing one of the finest agricultural water delivery systems in the Northwest. Three deep basalt wells are interconnected with five lined reservoirs/bulges and nearly ten miles of buried pipeline to provide a total capacity of over 5,000 gallons per minute. State-of-the-art telemetry-controlled variable-frequency speed pumps, booster pumps, and motors are designed to deliver 5 GPM per irrigated acre to each vineyard property site.

Summers in the Walla Walla Valley are dry and the soil is parched, with precipitation for July, August and September averaging less than 2 inches (5 cm). A fully committed active irrigation and canopy strategy that brings water to the roots and sun to the leaves and clusters is critical. Of equal importance is the understanding that different grapes at different terroirs have variable water needs. As such, each block has its own zone so that water delivery can be individually tailored depending on the differing requirements of the soil, plants, and winery. The XL Vineyard team also works to ensure that water is able to penetrate the soil to allow for deep roots. Improper water techniques can create a hardpan layer under the surface that will result in water not being able to penetrate but only remain on the surface and then create a run off issue (erosion) and to result in shallow roots.
