thanks, Spartan for you valuable input. I think my error was in assuming that 1 psi drop along the 50-ft lateral would be insignificant. 1 psi is very significant, it turns out, if 5-ft is the target head. Just curious - how did you arrive at 5-ft?
For my project, the contractor was able to...
Update - the contractor has built the system using 12" spacing and it was determined that the flow was not being distributed evenly. He reduced the spacing of the openings to 48" and it functioned acceptably.
Here is the type of installation we are doing:

Thanks for any help with the orifice sizing / spacing design.
Sorry, I was not clear but this is a pressure distribution line inside the void space of an ARC chamber drainfield (Infiltrator systems). This type of system is required in Florida for systems with more than 1,000 gpd of flow. The purpose, aside from the needed lift, is to evenly distribute...
I am designing a septic drainfield to recieve pumped effluent.
The drainfield will contain six dead end leaders, each 50-ft long. The estimated flow rate is 40 gpm, or 6.7 gpm per leader. Orifices spaced along the leader will allow the effluent to exit onto the drainfield surface. The...
Thanks for all the suggestions. We have proposed a concrete slab with waterstop at the doorways. I think the City Engineer will accept this. I can post more if he does accept it.
We are preparing a site plan for an auto body facility that will have a paint booth inside. At the roll-up doors nearest the paint booth, there is a concern (from the City Engineer) about contaminants seeping into the soil where the building slab meets the site pavement. The City Engineer is...
