Dakota Earthworks handles the excavation and trenching for waterline and sewer lateral connections on residential properties throughout Central North Dakota, with primary focus in McLean County (Washburn, Garrison, Underwood, Wilton, and surrounding communities) and Burleigh County (Bismarck and Lincoln).
Whether you're connecting a new home to municipal water and sewer, replacing a failed service line, or installing a curb stop on an existing connection, we provide the excavation, trench work, pipe bedding, and backfill. We coordinate with licensed plumbers and municipal inspectors as part of the process — you don't have to manage multiple contractors independently.
Types of Projects We Handle
- New residential water service connections — tapping the municipal main for a new home
- Sewer lateral installation — new connections from structure to municipal sewer main
- Curb stop installation — shutoff valve at or near the property line
- Saddle tee connections — tapping an existing water main without cutting
- Water service line replacement — failed, leaking, or undersized service lines
- Sewer lateral replacement — deteriorated or collapsed laterals
- Utility trench excavation for water and sewer in new construction
- Trench backfill and compaction to municipal or county specs
- Coordination with city/county inspectors for required inspections
Our Process
Site Review
We confirm main locations, property line, and trench route. Coordinate with the city or county on tap permit requirements.
Locate Utilities
Call 811 before any digging. We identify all buried utilities in the trench path before excavation begins.
Trench Excavation
Trench dug to required depth — typically 7–8 feet for water in Central ND — and width to allow proper pipe bedding.
Pipe & Connections
Pipe bedded and installed to grade. Curb stop, saddle tee, or lateral connection made per project requirements.
Inspection
Municipal or county inspector called for required inspection before backfill. We coordinate scheduling.
Backfill & Restore
Trench backfilled and compacted in lifts to required density. Surface graded and restored.
North Dakota Conditions — What Makes This Work Different
Waterline and sewer lateral work in Central North Dakota demands more care than in warmer climates. Water lines that aren't buried deep enough freeze — and in this part of ND, that means getting below frost lines that routinely reach 6–7 feet in severe winters. A line installed at 5 feet may work most years and fail in a hard one. We trench to the depth the project requires, not the minimum we can get away with.
The clay soils common throughout McLean and Burleigh Counties also require attention during backfill. Clay doesn't compact the same way granular material does — improper backfill technique leaves voids that settle over time, damaging pavement, driveways, and yard grade above the trench. We use proper lift thicknesses and compaction to avoid those problems.
Coordinating with municipal public works in Washburn, Garrison, Bismarck, and surrounding communities is part of the job. We're familiar with local tap permit processes and what inspectors in the area expect to see before they sign off.
Pricing
Waterline and sewer lateral costs vary based on trench length, depth, soil conditions, pavement or surface restoration, municipal permit fees, and whether plumber coordination is required. Every project is site-specific. Call us at 701-773-DIRT (3478) with your project location and scope and we'll give you a straight estimate.
Frequently Asked Questions
Do I need a licensed plumber for waterline or sewer lateral work in North Dakota?
The excavation and trenching portion of waterline and sewer lateral work is performed by Dakota Earthworks. Depending on the scope and county requirements, a licensed plumber may be required to make the final connections at the main or at the structure. We coordinate with plumbers regularly and can help you understand what your specific project requires.
What is a curb stop and why does it matter?
A curb stop is a shutoff valve installed on a water service line, typically near the property line or right-of-way. It allows the water supply to a property to be shut off without affecting the main. Proper curb stop installation is required by most municipalities and is part of every new water service connection we install.
How deep do water and sewer lines need to be in North Dakota?
In Central North Dakota, water service lines typically need to be buried at least 7 to 8 feet deep to stay below the frost line and protect against freezing. Sewer laterals are generally shallower but must maintain proper slope for gravity flow. Exact depth requirements vary by municipality and site conditions — we trench to the required depth for your specific location.
What is a saddle tee connection?
A saddle tee is a fitting that clamps onto an existing water main and allows a new service line to be tapped in without cutting the main. It's commonly used for new residential water service connections where a full main cut isn't practical or required. We install saddle tee connections as part of new waterline service work.
How much does waterline or sewer lateral installation cost in North Dakota?
Costs depend on trench length, depth, soil conditions, access, and whether coordination with a municipality or licensed plumber is required. Every site is different. Call us with your project details and location and we'll give you a straight estimate.
