This two day workshop will focus on the design and installation of a pressure distributed system.  Students in the classroom will utilize the results from a site and soils evaluation to design a pressure distribution system and apply it to a trench system design.  It is recommended that participants also attend the Site & Soils Day Workshop, which takes places at the same site on September 21, 2015.

The expected outcomes for this training are listed below, and a registration form is attached. You may register for this hands-on training by fax, email, or online. Please contact the WCOWMA office with any questions you may have.

 

Install Training Workshop Outcomes

Pressure Distribution

• Basic understanding of Pressure Distribution method and able to design basic system:
• Recognize difference between pressure distribution only to head of treatment field laterals and of distribution through entire lateral length.
• Know the advantages and disadvantages of pressure distribution.
• Understand and able to determine orifice size/spacing from tables.
• Able to determine desired/required dose volume
• Understand benefits of timed interval dose volumes over demand dosing
• Calculate piping friction loss pressure head, total head and apply to piping and pump selection
• Ability to use related tables in SPM

• Know the basic advantages of pressure distribution and able to design basic pressure distribution lateral systems and determine pump performance requirements.

 

Seepage Trench system

• Understand basic principles of how trench systems work – incl dispersal horizontally. Apply soil evaluation information.
• Learn trench system design configurations and materials; sand layer, fill, gravel, chambers.
• Basic knowledge of utilizing topography of installation site.
• Know factors in locating the trench system– slope vs. level, clearance separations, vertical separations, fill materials for raised trench system.
• Ability to design pressure distribution laterals for trenches, orientation of orifices, spacing, preferred vs. cost.
