Living off the grid or in areas without municipal sewer systems requires a septic system for wastewater disposal. Colorado’s diverse landscapes and environmental regulations present unique considerations for septic system installation. Here are 7 essential things you need to know before installing a septic system in Colorado:
1. Know When You Need a Septic System

Not all properties in Colorado require a septic system. If you have access to a public sewer connection, that will likely be the most cost-effective and environmentally friendly option. However, if a public sewer connection isn’t available, a septic system is the way to go for proper wastewater treatment.
2. Permits and Regulations
Installing a septic system in Colorado requires permits from your local health department and potentially the Colorado Department of Public Health and Environment (CDPHE). The permitting process ensures your system is designed, installed, and maintained according to state regulations to protect public health and the environment. Hiring a licensed septic system installer familiar with the permitting process can save you time and hassle.
3. Site Evaluation is Crucial
Before you can design or install a septic system, you need a thorough site evaluation. This evaluation, conducted by a licensed professional, will assess your property’s soil composition, drainage, water table depth, and slope. These factors will determine the type, size, and placement of your septic system.
4. System Design Matters

Based on your site evaluation, a septic system design will be created. This design should consider the number of bedrooms in your house, anticipated wastewater flow, and the results of the soil test. A properly designed system will function efficiently and protect your property and the surrounding environment.
5. Choosing the Right System
There are different types of septic systems available, each with its own advantages and disadvantages. Common options in Colorado include:

• Conventional Septic Systems: The most common type, with a septic tank for settling solids and a drainfield for liquid effluent dispersal.
• Alternative Septic Systems: May be necessary for sites with poor soil drainage or limited space. These can include sand filters, mound systems, or aerobic systems.

6. Installation by a Qualified Professional
Septic system installation should only be performed by a licensed and qualified professional. They will have the expertise and experience to ensure your system is installed correctly according to the design and local regulations.
7. Proper Maintenance is Key
Regular maintenance is essential for the proper functioning and longevity of your septic system. This includes having your septic tank pumped every 3-5 years by a licensed professional and avoiding activities that can harm the system, such as pouring harsh chemicals or grease down the drain.
By following these 7 essential tips, you can ensure a smooth septic system installation process in Colorado and enjoy peace of mind with a properly functioning system for your home.
