[Owtsinfo] Attention OWTS Professionals – Revised Eljen GSF Certification and Manual - November 2018 (List of Approved Technologies updated 11/16/18)

[owtsinfo at listserve.ri.gov]

The RIDEM Alternative OWTS Technology Certification issued to Eljen Corporation for Geotextile Sand Filter (GSF) and the associated manual for design, installation and inspection have been revised (see attached). These two documents are also available via links within the list of approved technologies posted to the RIDEM website. This updated list was posted November 16, 2018. The  List of Approved Technologies is available on the RIDEM website at http://www.dem.ri.gov/programs/benviron/water/permits/isds/pdfs/ialist.pdf.

Overview of Changes: The primary reason for the certification and design manual updates associated with Eljen GSF was to review and approve Eljen Corporation’s decision to require venting when cover over the system exceeds 18”, rather than 24” as previously specified. The certification was also updated to reflect some of the newer elements RIDEM has been incorporating into more recent certifications, including reference to the associated design manual revision date. To minimize confusion as to which version of the manual has been approved for use in RI the date of the approved manual has been incorporated into the technology certification document. In addition, a pdf version of the approved manual has been made available on the DEM website (see link shown above).
