In 2020, Bryan Hauger and Dave Stewart were each recognized with a Municipal Leadership Award from the PE Pipe Alliance for the contributions of Bryan Hauger Consulting to completion of a major milestone in the $20 million Bel Marin Keys Unit V Hamilton wetlands restoration project near Novato, California.  The award reads "In recognition for outstanding achievement and leadership for environmentally sustainable use of HDPE pipe".

The U.S. Army Corps of Engineers together with the California Coastal Conservancy completed a major milestone in the $20 million Bel Marin Keys Unit V Hamilton wetlands restoration project near Novato, California in 2020 with the assistance of Bryan Hauger Consulting. The construction of the new 2-mile bayfront levee allowed for the next phase of the wetlands restoration project to begin. When completed, the new wetlands restoration project will allow bay waters to eventually reclaim 1,600 acres of former tidal marshes that had been previously drained for agricultural and development purposes. These reclaimed tidal marshes provide critical habitat for wildlife while also acting as a buffer against storm surges. 

Where the new levee ties-in to the old one, a 1,080-foot section of HDPE pipe had to be installed up and over the levee to tie-in to the existing Novato Sanitary District (NSD) effluent outfall pipeline. The NSD pipeline is a 54-inch diameter concrete pipeline.  850-feet of the NSD outfall was abandoned under the new levee footprint. The new 63-inch iron pipe size (IPS) high density polyethylene (HDPE) pipeline travels up and over the new levee. A 20-foot valve vault with air blow-offs and vacuum breakers was also installed on top of the levee.
​
​The California Coastal Conservancy recognizes the importance of these wetlands and the issues that could be created with a failure of these pipes. The leakage of any effluent water from the 63-inch HDPE pipeline could severely compromise the integrity of the levee, leading to potential failure of the levee causing property destruction and contamination of critical wetlands.  For these reasons, the Coastal Conservancy required the services of Bryan Hauger Consulting (BHC) to provide butt fusion joining inspection services during the construction of the 1,080-foot long 63-inch HDPE pipeline. Onsite inspections were carried out by David A. Stewart who has decades of experience in water and wastewater operations and is a McElroy Certified Inspector for HDPE pipe fusion joining.  By ensuring the integrity of the HDPE butt fusion joints for this waste water project, Bryan Hauger Consulting played a critical role in making sure the project was completed right the first time and on time.

If you need inspections on your pipelines, let Bryan Hauger Consulting help you.  Our inspectors have years of ensuring pipelines are built right the first time, saving time and money on any size project.
