Underground Utility Services in Denver
Rocky Ridge Excavating provides professional underground utility installation for commercial, municipal, and residential development projects across Greater Denver. From water and sewer mains to storm drainage, gas lines, electrical conduit, and communications infrastructure, we handle every phase of underground construction — from initial locate and layout through final backfill and compaction.
Our Underground Utility Services
Water Lines
We install and replace water mains and service laterals for projects of every scale. Our crews work confidently with ductile iron, PVC, and HDPE pipe, and we maintain strict compliance with local utility standards and inspection requirements throughout every installation.
Sewer Lines
We install sanitary sewer lines and service laterals to line and grade using PVC, HDPE, and concrete pipe. From bedding and jointing to backfill and testing, we build every run to meet local utility standards and inspection requirements.
Storm Drainage Systems
Effective stormwater management starts underground. We install complete storm drainage systems including catch basins, reinforced concrete pipe, corrugated HDPE, and detention or retention structures. Whether you need a new subdivision storm system or a commercial site tie-in, we build it to spec and to grade.
Every project starts with a thorough plan review and site evaluation. We coordinate with engineers, general contractors, and local utility providers to confirm line locations, depths, slopes, and tie-in points before any excavation begins. Proper planning eliminates surprises and keeps your project on schedule.
Our Installation Process
We follow a structured process on every job. First, we verify existing utility locates and establish control points. Then we excavate to grade, install bedding material, lay pipe or conduit, and complete all required inspections before backfilling. Every trench is compacted in lifts to meet project specifications and prevent future settling.
We provide underground utility installation services throughout Denver, Aurora, Lakewood, Centennial, Littleton, Parker, Arvada, Firestone, Longmont, Greeley, Colorado Springs, Winter Park, Buena Vista, and the surrounding Greater Denver area. Our crews work on commercial developments, municipal infrastructure projects, and residential subdivisions across the Colorado Front Range.
Frequently Asked Questions
How long does a typical utility installation take?
Timelines depend on the scope, soil conditions, depth requirements, and weather. A straightforward water or sewer lateral might take one to two days, while a full subdivision utility package with multiple runs can take several weeks. We provide detailed schedules during the estimating phase and keep you updated throughout the project.
What types of pipe and conduit do you install?
We work with a full range of materials depending on the application — PVC, ductile iron, HDPE, corrugated HDPE, reinforced concrete pipe, and various conduit types for electrical and communications. Material selection depends on the utility type, local codes, depth, and project engineer specifications.
Do you handle permitting and utility locates?
We coordinate all required utility locates through Colorado 811 before any excavation begins. For permits, we work closely with local municipalities and utility providers to secure the necessary approvals. Our team handles the paperwork and scheduling so you can focus on the rest of your project.
What types of projects require underground utilities?
Underground utility installation is required for virtually every type of development — new commercial buildings, residential subdivisions, municipal road projects, industrial facilities, and site redevelopments. Any time a building or site needs water, sewer, storm drainage, gas, electric, or communications service, underground work is involved.
Can you work around existing underground infrastructure?
Absolutely. We regularly install new utilities in areas with existing underground infrastructure. Our crews use utility locates, potholing, and careful hand excavation to identify and protect existing lines. We maintain safe separation distances and coordinate with utility owners to avoid conflicts and service interruptions.
What areas do you serve?
We serve the Greater Denver-Denver area and surrounding communities throughout the Colorado Front Range. Our crews regularly work in Denver, Aurora, Lakewood, Centennial, Littleton, Parker, Arvada, Firestone, Longmont, Greeley, Colorado Springs, Winter Park, Buena Vista, and surrounding communities throughout the Colorado Front Range.
