What is the reserve area for?

It's space held open for a replacement leach field if the first one fails. Many counties require it on the site plan, so check your local rules.

Can I add more leach trenches?

Yes! Copy a trench in ArcSite and connect it to the distribution box to match the field size your perc test calls for.

Can I get paid for the septic install in ArcSite?

Yes. Payments sit in ArcSite next to your drawings and proposals, so the homeowner isn't sent off to a separate app to pay you.

A septic system lets a home on a rural lot handle its own wastewater, with no sewer line out to the street. ArcSite's septic system leach field diagram lays out the tank, distribution box, and leach trenches on the lot, along with the well setback and a reserve area for a future field.

Lay out the well setback before anything else, because it decides where the tank and trenches can't go. Draw your customer's lot to scale in ArcSite, and you can show the health department and the homeowner that every setback clears.
