Drain to beach
Drain to beach
(OP)
We are trying to design an appropriate method of draining stormwater from a water treatment facility to the nearby coastal area. Currently the facility has a splash pad that is constantly being buried under blowing sand. An idea that was brought up was to use perforated pipes buried under the sand to disperse the storm water, but I'm having trouble finding any resources as to length/size of the pipes. I know that this is similar to a leach field design, but I don't need to have the treatment capabilities of a leach field, so I think that I wouldn't need as large an area. Does anyone have any experience in this sort of problem that can give me any recommendations as to good references or design ideas.
Thanks

Does the flow from the pipe have enough force to clear the end if it becomes buried?
Is the problem erosion? If so, what is occurring?
If this outlet is to a beach that is dynamic, I would think that the burial of perforated pipes might work in the short term, but they could potentially become uncovered.

I have the total cross-sectional area of the "discharge" perforations double the toal cross-sectional area of the "collection" perforations. One of these systems has been in use for over 10 years and works well, but slowly. Suggest the ratio of "total discharge port cross-section" to "total collection port cross-section" be increased substantially - an educated guess, maybe 10:1 or 20:1
