Objective:

The landscaping at the William Jefferson Clinton Building West, Constitution Avenue entrance serves as an exhibit area to demonstrate several innovative features, including water conservation and planting techniques using low-maintenance and sustainable materials.

Description:

The William Jefferson Clinton Building West garage cisterns are designed to capture runoff from the approximately 10,000 square feet of roofing at the Federal Triangle Complex. Stormwater is intercepted from downspouts and diverted to cisterns installed in the West building parking garage. There are six 6-foot diameter cisterns installed in a row that provide a reservoir of water for the William Jefferson Clinton Building West irrigation system. The last tank includes an energy-efficient pump that is used to supply irrigation water to the landscaped areas. The six cisterns hold enough water to irrigate the landscaped areas for up to 1 ½ weeks. The project was completed in summer 2008.
