I would appreciate any references or direction to examples of drainfield design for a .4 MGD WWTP.  I have the standard water and wastewater tecnology manuals but no specifics.

Location: Florida

Thank you for any insight.

If you have a Waste Water Treatment Plant, why do you need a drainfield?  The local receiving body, stream or river, can accept effluent that meets EPA regulations.  If you want tertiary treatment, I suggest a shallow pond or marsh bed with a sand/gravel dike at the perimeter for outflows.

What questions do you have?  A 400,000 GPD drainfield is pretty large and complex.  Take a look at squirtonsite.com for pressure distribution system software
