Plastic septic tanks — Longmont, CO
Last updated: September 24, 2026
What affects the price
The final bill for septic work depends on a few specific variables. First, the size of your tank and the total volume of waste removal play a role. We also look at the accessibility of your tank lids; if they are buried deep underground or hidden under landscaping, extra labor is required to reach them. The distance from our truck to the tank also impacts the setup time. Every property has unique plumbing needs, and exact pricing is confirmed free on the call.
About this service
Modern plastic septic tanks are durable, lightweight, and resistant to the corrosion that can affect traditional concrete models. They are often chosen for new installations or replacements because their seamless construction reduces the risk of leaks. If you are building a new home or need to replace a damaged unit, these tanks offer a reliable, low-maintenance solution. We can help determine if a plastic model is the right fit for your property’s soil conditions and household size.
