Septic design

Bedrooms (drives sizing):
Soil & site
SSURGO per-parcel soil not yet wired; pick a class.
System type
Septic tank
Field geometry
Auto-sized from design flow / SAR; override to match a real layout.
Sizing overrides
Every value is computed from MCESD code by default. Type a number to hand-spec it; clear the box to revert to recommended. Overrides are honored even below code minimum and are flagged.
Well & reserve
100 ft well setback is fixed ADEQ/MCESD code. Use the 💧 Well tool to place it; for a neighbor well you may place it off the parcel.
Documents & export
Export renders the on-canvas design as a formal B&W engineering as-built sheet (title block, plan, spec table, setbacks, basis). Generate a design to enable.

Components
House / dwelling - size drives bedrooms
Outbuilding - shed/garage; keep-out only
Septic tank - settles solids; divider = 2-comp
D-box / dose - splits flow to the field
Drainfield - soaks water into the soil
Reserve area - spare field, code-required
Well - water source
Setbacks (dashed)
10 ft to house · 5 ft property line
100 ft from any well
Dispersal type (field color)
Trench - parallel gravel lines
Seepage pit - round dry-well discs
Chamber - gravelless arch rows
Bed - one wide hatched pad
Mound - raised bermed pad
Drip - dotted emitter grid
Design source
Generated design - solid colors, our estimate
Recorded as-built - dashed blueprint, county record
Soil / percolation
Sand ~5 min/in (fast) · Sandy loam ~15 (desert default)
Loam ~30 (moderate) · Clay loam ~55 (slow)
Caliche/hardpan ~90 (very slow). Slower perc = bigger field.
Not sure? Just press Auto-generate - it places a code-correct design for you.
Drawing tools failed to load from CDN. Falling back to drag-the-house mode; auto-generate + sheet still work.
