The new "FIELD GUIDE
FOR MOUND DRAINFIELD CALCULATIONS"
158 pages of easy to understand measurements available for soil testers, designers and installers. Basically all residential mound drainfields are included. You will find mound lengths and widths, cell lengths and widths, different sand fill depths and estimates for required sand fill volume in the mound. A DREAM for those contractors who bid mound drainfields - takes the guessing out of sizing and sand fill estimating!
