Presentation: Hobas Pipe 101 by Mike Garcia, Area Manager of Hobas Pipe USA. Mike provided an informative and comprehensive presentation on: 1. Centrifugally Cast Fiberglass Reinforced Polymer Mortar (CCFRPM) Product and Process 2. Product Performance testing 3. Competitive Analysis 4. Applications 5. Local projects Highlights of the presentation include:

• Hobas has 22 factories. Sizes 18”-110”; due to shipping costs anything 30” or less is cost-prohibitive. Sections are 20’, but can be smaller depending upon the needs of the project.

• Hobas strengths are in gravity sewers. Applications include direct bury, microtunneling and jack-and-bore, sliplining, above-ground installations, tunnel carriers, and pipe bursting.

• CCFRPM is made of glass, resin and sand. Outside layer is UV resistant. This product lasts forever. C=155. o vs. PVC C905 – less brittle and doesn’t allow infiltration/exfiltration o vs. HDPE – allowable deflection compounded over lengths can cause problems

at downstream tie-in points. o vs. DIP – can sometimes be out of round.


o vs. Polymer Concrete – OD’s may be inconsistent; bearing strength loads low per ASTM Standards.

o vs. VCP – cradle needed at joints. o vs. Filament-Wound – made around a mold (built from inside, out); hydrogen

sulfide reduces ability to handle strain. • Hobas specification: Type 1, Liner 2, Grade 3. • Corrosion resistant and has long life. Hobas also provides great service for free. • Joints/Couplings – gasketed. Easy to cut with diamond tip saw in field. Can make

manholes, T’s, elbows, reducers. • Hobas pipe does withstand hydrocarbon contamination. • Can jack up to 800’ lengths. • Watch out for microtunneling operations in rock – rock grindings thrown back from

the head will break pipe. Check geotechnical data very well before using! • Prequalification of contractor is recommended for Hobas applications, especially with

larger diameter pipeline applications. • Local project: Hunter’s Point: PG&E will install 36” by microtunneling. Construction

slated June 22nd & 23rd. Length is 1000 lf. Later will be installing 72” by open cut construction.

• Can do elliptical/horseshoe-shaped and ship from overseas. Cheaper to barge from Europe then ship via truck cross-country.

• May be issues with permafrost in uncovered or shallow installations. • Hobas doesn’t have any restrained joints here in the USA. Biggest competitors are

T-Lok, lined RCP, and VCP. Handouts included:

• The Complete Hobas Guide: Facts and Specifications • “What’s in Your Pipeline” brochure by Hobas • Pipeline Newsletter – January 2008

A big thank you to Mike for this presentation! General: June 17, 2008 Meeting Minutes: A motion was made to approve the minutes, which was seconded and minutes are approved with no corrections. Board of Directors Election Results: It was very close for two of the three positions, but after tallying the votes the new Chairman is Jonathan Lee of West Valley Sanitation District, the incumbent; Vice Chairman is Cindy Preuss of Harris & Associates, the former PUG Secretary; and Secretary is Roberts McMullin of URS Corporation. Congratulations to our new Board of Directors, and a huge thank you to Jennifer Glynn for her many years of excellent service with and contributions to the group as Vice Chairman. Jennifer will be sorely missed. Transition of Board of Directors: The new Board of Directors will assume their positions as of July 1, 2008. Transition of the Secretarial duties will be ongoing for a few months, but the members should expect to start seeing announcements and other PUG related news items and alerts being sent by Roberts McMullin as of July. Of course any member may contact Cindy for PUG related issues as they so choose – any individuals serving on the Board welcome and value the input, suggestions, and feedback from our members. Website Update: Cindy has been in contract negotiations with the selected PUG website consultant and is getting ever closer to having a signed contract. Once the contract has been signed, work on revamping the website is expected to start immediately.


Announcements: The ‘08/’09 membership renewals are due now! The renewal applications were sent by Cara last week. Remember that membership has numerous benefits, such as discounts on the upcoming CIPP course, participation in random raffles held at random monthly meetings, discounts on attending the annual seminar, etc. Get your renewals and/or new member applications in today! The Pipelines 2008 Special Conference Event is coming up July 24, 2008 in Atlanta, GA. Focus presentation will be given on, “Potholing From a Contractor’s Perspective.” WEF Specialty Conferences 2009 Call for Abstracts is out. Conferences include Disinfection 2009, Collection Systems, and Residuals and Biosolids. APWA Public Works Congress & Exposition will be held August 17-20, 2008 in New Orleans, LA. Deadline for Early Bird Registration is June 20. Geospatial Holdings, Inc. just announced a new Tension/Calc3D™ Technology which is an automated bend radius, joint integrity and pulling tension software for the electrical & distribution industry. SCC puts out The Boring Bulletin covering, among other things, lunch & learn classes offered monthly. June 5th was an Intro to Pipe Bursting, July 3rd is Benefits of S.U.E., and other monthly classes are listed through October. These classes are free. Please contact or see Cindy for further information on any of these above announcements. Project Discussions: Jonathan Lee spoke of a 30 lf broken sewer line that took three months to repair. Break occurred in the middle of the night and a $20K spot repair was expected to fix. Break was located between a box culvert and a hidden bridge abutment 25 feet deep. Boring contractor was to bore under the box culvert. Launching pit revealed other end of the bridge abutment that had to be removed. 18-inch top to 3-foot bottom with 1-inch rebar @ 6-inches on center for the bridge abutment required two excavators to remove. Location is the busiest street in Las Gatos. Original backfill was sand, so a 30 by 50-foot pit was required at the launching site, requiring 15 trucks. Final installation included a 24-inch steel casing housing 6-inch to 10-inch sewer pipe. In the end it took $425K to finally fix the problem. Jonathan Lee also reported on a project that is out to bid with the bid opening due in August. As part of their I&I reduction program, 13,000 lf of 6 to 8-inch pipe bursting upsizing and 1000 lf CIPP is slated for construction, including lateral replacements. Sasha Mestetsky reported that overall CSAN is seeing bids that are roughly 40% below average prices. Excellent bidding climate. Cindy Preuss asked if anyone had experience directionally drilling two laterals piggyback in one bore. She’s seen it done with a small conduit atop a larger pipe for pressure lines, but nothing of that nature for gravity where exact grades are imperative. No one in the group had experience with this, although it was suggested that if piggybacking of two small gravity laterals is uncommon, might consider drilling one larger lateral between homes, then splitting the laterals to service adjacent homes in the backyards. Richard Barge of Ameron International and Sasha Mestetsky of CSAN provided an update on the CSAN A-line tunneling project. A 92-inch is being jacked under the creek, and also included is a 72-inch microtunnel TBM. Richard provided information on contacts for site visits to Cindy; Cindy will forward information to the group.


Next Meeting: Our next meeting will be held TUESDAY, JULY 15, 2008 at the offices of Brown & Caldwell located at 201 N. Civic Dr., Suite 300, Walnut Creek, CA. The topic will be on Recent Updates with Ductile Iron Pipe: Corrosion Control, Horizontal Directional Drilling, and Fittings, given by Rosemary Smud of American Ductile Iron Pipe. Please call (510)874-3102 or email [email protected] to RSVP.
