Greenroof Project of the Week for July 29, 2013: Ellis Creek Water Recycling Facility

on July 30, 2013 at 9:04 am under Project of the Week: 7/29/13

Ellis Creek Water Recycling Facility
Petaluma, CA, USA

12,174 sf. Greenroof

Project Description & Details

The Ellis Creek Water Recycling Facility has two buildings that were designed with extensive living roofs, incorporated into the facility’s design program to demonstrate the viability of this technology toward promoting environmental sustainability. After conducting an assessment report in 2011, SYMBIOS was hired and initiated a complete overhaul of the initial 2009 roof system.

Using a Tremco system, a planting plan was developed with sweeping fields of 13 succulent species to create an impression of flowing movement that follows the main axis of the building. The roofs are irrigated directly by utilizing the tertiary treated wastewater from the facility’s operations. In the western United States where seasonal drought is an annual event this green roof project clearly demonstrates the appropriate use of this reclaimed water resource. In order to meet a net zero runoff requirement goal for the project, the living roof was integrated with a series of ground level bioswales and rain gardens.
