About BJSoftware

BJSoftware has been designing on-lot septic systems in Pennsylvania using its proprietary software since 1982. BJSoftware is licensing the latest version of its software to a limited number of designers who want to increase their efficiency, enhance their quality, and better serve their customers.

Our turnkey design package creates complete designs with all the necessary drawings, spec sheets, instructions, and calculations for sand mounds, at-grades, and peat-based systems. It even has an easy-to-use built-in CAD system to automate plot plan creation.

Since 1987 BJSoftware has been a wholly owned subsidiary of Rules of Thumb, inc.
