Design: Pressure Distribution (1.5 hr)

Low Pressure pipe systems use a pump to move effluent to an infiltrative surface under pressure. The goal of this approach is to uniformly dose, then rest this surface multiple times per day. The availability of free or low cost spreadsheet and computer programs has made the analysis of lpp designs accessible. Special areas of concern such as designs on sloping lots and in freezing conditions will be discussed. This presentation aims to provide a standard of practice highlighting the advantages of the pressure distribution approach, illustrating key decisions via a design example, sharing typical calculations, describing tricks, traps, rules of thumb, and designs that promote constructability and ease of operation and maintenance.
