Thanks for visiting! The Macaw team was acqui-hired by Invision in January 2016, at which point Macaw was sunsetted. The software and book are no longer available, but this we're keeping this website up as a reminder of the fun we had. If you're interested in what the Macaw folks are up to now, go check out Clover.
3 Compartment Septic Tank
| Feature | 1-Compartment | 2-Compartment | 3-Compartment | |---------|---------------|---------------|----------------| | | ~50–60% | ~70–75% | ~85–90% | | Risk of drainfield clogging | High | Medium | Low | | Required pumping frequency | Every 1–2 years | Every 2–3 years | Every 3–5 years | | Cost to install | Lowest | Moderate | Higher upfront | | Long-term drainfield life | Shortest | Medium | Longest |
The partially clarified water flows through a baffle into the second chamber, where finer particles continue to settle.
A is an advanced primary treatment system designed to provide superior separation of solids and clearer effluent compared to standard single- or double-chamber tanks. By utilizing three distinct rooms, the system increases the wastewater's retention time, allowing for more thorough biological decomposition and settlement. System Design & Operation
Disclaimer: Regulations vary by location. Always consult your local health department or permitting office before installing or modifying a septic system.
To mitigate these issues, the multi-compartment design—specifically the three-compartment septic tank—has been developed. This configuration introduces internal baffling to create a series of treatment zones, ensuring a "plug flow" pattern that maximizes retention time and treatment efficiency.
This is typically the largest chamber, where heavy solids (sludge) sink to the bottom and lighter materials like grease (scum) float to the top.
About the Authors
Joe’s a dinosaur by Internet standards, having first used the Web in text mode on a dial-up Unix system in the mid-1990s and learning HTML in the late 1990s. In any case, he got a little hooked and has been a web professional since 2000, operating the mostly one-man web studio ShooFly Development and Design. He has also been a drummer for more than half his life, which is frankly alarming. He lives in Los Angeles with his wife and their frequently adorable, occasionally noisy cat.
Rex has loved making things on the computer since his family got their first one in the early 1990s, trying out any design applications he could get his hands on. After graduating with a degree in digital illustration, he got a job at an interactive agency in the early 2000s and quickly became a big fan of designing things for the web. He’s an art director at a marketing and design agency in Grand Rapids, Michigan, where he lives with his wife and their two pets. 3 compartment septic tank
