Biosolids & Storm Water Workshop

2017 Biosolids & Storm Water Workshop

On May 26, 2017, HWEA’s Biosolids/Co-Generation and Storm Water Quality Committees hosted the second HWEA Biosolids/Storm Water Workshop at the Manoa Grand Ballroom. The workshop was attended by 99 registrants, 10 exhibitors, and 23 speakers.

Biosolids Track

The Biosolids session started off with an overview of opportunities for renewable energy including biogas and struvite recovery by Jeremy Holland of HDR.  Mike Barnes of Kennedy/Jenks Consultants then discussed the various mixing options available for anaerobic digesters.  Luke Werner of Kennedy/Jenks Consultants discussed considerations for covering anaerobic digesters, including things to look for when retrofitting them.  Paul Christy with Cambi presented on thermal hydrolysis and potential benefits to applications here in Hawaii.  Eric Wanstrom with Schwing Bioset discussed their model for recovering struvite from the digestion process.  Gavi Subramanian with Kennedy/Jenks Consultants discussed her research on digester foaming.  Craig Johnson of Clipper Controls presented a new method for measuring biogas flow rate.  And Mel Carmichael of Synagro wrapped up the workshop by discussing Sand Island’s biosolids production and distribution.

Storm Water Track

The Storm Water Track was a huge success as attendees packed the room eager to listen on the latest storm water developments. The track was divided into three categories; 1) Industrial, 2) Municipal, and 3) Construction with an overview of storm water from a national perspective, trends, and market-based approaches. Seth Brown, principal and founder of Storm and Stream Solutions, LLC in Virginia, was the keynote speaker as he presented on the overview of storm water from a national perspective, MS4 Program Evolution, and the Chesapeake Bay Overview.

A big mahalo goes out to:

  • Manoa Grand Ballroom which served as the venue for the event
  • Mel Carmichael (Synagro) and Craig Johnson (Clipper Controls) who stepped up as emergency speakers on the Biosolids side
  • Out of town speakers; Mark Ambler (Weston Solutions), Ross Dunning (Kennedy Jenks/Consultants), and Seth Brown (Storm and Stream Solutions, LLC)
  • Robin Matsunaga (Belt Collins) who stepped up as an emergency speaker on the Storm Water side

2015 Biosolids & Water Quality Workshop

The Hawaii Water Environment Association hosted an inaugural worshop on May 28, 2015 at the Manoa Grand Ballroom at the Japanese Cultural Center. This workshop featured two important topics to Hawaii’s future in becoming a sustainable environment: Biosolids and Stormwater.

With respect to Biosolids, this technology is not at the forefront of waste management and we hope that this conference will shed some light as to what biosolids can offer. There will be speakers presenting on Oahu’s current masterplan for implementing biosolids and various biosolids technologies. There will also be speakers from the mainland to share their experiences and offer a different perspective on biosolids.

Stormwater principles are frequently changing and the speakers at this workshop will discuss the latest trends and technologies. Along with changing principles, the regulatory requirements are also constantly being modified and so a forum of city and state agencies have been assembled to discuss their Municipal Separate Storm Sewer System (MS4) Programs and be available for questions the audience may have.
