Services & Process

Excavation services form the backbone of what Extreme Construction does, covering everything from trenching for new septic installations to large-scale earthmoving for construction projects. Backflow services are especially relevant for commercial and mixed-use properties, where preventing contaminated water from flowing back into the clean water supply is both a safety and code compliance issue. Septic services round out the offering, including system inspections, tank pumping, and drain field work for properties that aren't connected to municipal sewer lines.

Service Area

Extreme Construction serves Greenwood Village and the broader south Denver metro area, including Centennial, Littleton, and Englewood. They're well-positioned to reach commercial corridors along I-25 as well as residential neighborhoods throughout Arapahoe County.

Frequently Asked Questions

What is a backflow preventer and do I need one?
A backflow preventer is a device that stops contaminated water from flowing backward into your clean water supply, which can happen when there's a sudden pressure change in the system. Many municipalities require them on commercial properties, and some residential properties with irrigation systems or fire suppression lines need them too. Your provider can test your existing device or install a new one if required.
Can excavation damage my existing septic system?
It can if the excavation crew doesn't know where underground components are located. That's why it's important to work with a provider that combines excavation and septic expertise, since they'll locate and account for existing infrastructure before any digging starts. Permits and underground utility locating are standard steps before major excavation work.
Do commercial properties in Greenwood Village need septic systems?
Most commercial properties in Greenwood Village are connected to municipal sewer, but some outlying or older properties still operate on private septic systems. Commercial properties with grease traps or high wastewater output have specific maintenance requirements that go beyond standard residential septic care.
How long does a septic system installation take?
A typical new installation takes anywhere from one to three days for the physical work, but the full timeline including permits and inspections can stretch to a few weeks. Projects that require significant excavation or unusual site conditions take longer. Getting permits pulled early is one of the best ways to avoid delays.
What triggers a backflow inspection requirement?
Local water utilities typically require annual backflow inspections on commercial properties, and the requirement can also be triggered by property renovations or changes in how water is used on site. Residential properties with irrigation systems connected to the municipal supply often need them too. Failing to keep up with inspections can result in fines or service interruptions.
Can you excavate near tree roots without killing the trees?
Experienced excavation crews can work carefully around established trees, but root damage is always a risk with deep digging. Hand digging or air spade techniques can be used near sensitive root zones when precision matters. Discussing your landscaping concerns before work begins helps the crew plan the least disruptive approach.
