Design Tools for Septic Systems and Wastewater Treatment by Orenco

Design Software

Design Aid Package

Orenco's Design Aid Package and CD-ROM is an invaluable tool for designers of onsite wastewater treatment systems. It includes Orenco’s stand-alone PumpSelect™ program that takes the guesswork out of sizing pumps and configuring carrier lines. PumpSelect™ provides fast, error-free hydraulic calculations and generates system curves. The latest Design Aid Package includes 32 completely updated STEP Equipment and Tank Drawings, as well as copies of Orenco's AutoCAD® drawings for intermittent and recirculating sand filters, pumping systems, and related products. To complete the package, we've included a DWG viewer (eDrawings™, from SolidWorks Corporation) and a PDF viewer (Adobe® Reader® from Adobe Systems, Inc.) on the CD-ROM.

PumpSelect 2.0

PumpSelect™ provides fast, error-free hydraulic calculations for pressurized and non-pressurized systems. It generates system curves that you can use to select Orenco pumps for your system.


PumpSelect File Converter

This is a small utility to convert old PumpSelect files (from versions 1.55 or earlier) to the new file format (version 1.7+).

EasyPak Select 2.0 and ProPak Select 1.0 Software Downloads

Orenco's new Biotube® EasyPak™ and Biotube® ProPak™ are the first pump packages designed specifically for use in pump tanks and septic tanks, respectively. To make system design calculations easier, Orenco developed EasyPak Select and ProPak Select software (only for use with Orenco products).

Both of these specialized versions of PumpSelect calculate tank sizing, reserve volumes, and timer settings. Calculations are completed automatically as input data is entered, and the resulting pump curves and tank drawing displays can be printed or exported. An FAQ for new users, pump technical data, and sample system drawings are included. You can download EasyPak Select and ProPak Select from the links below:
