Underground Utilities in Waxhaw & Charlotte

Stone Pro Grading, LLC installs underground water lines, sewer lines and storm drainage systems for homeowners, builders and developers throughout Waxhaw, Union County, Charlotte and surrounding areas. From a new home site to larger residential or commercial sitework, we help bring underground utility installation into your construction plan. Tell us about your property, utility needs and timeline so we can review the scope and prepare an estimate.

Water Line Installation

Underground water line installation for residential and commercial construction projects. Share your site plans and water service needs so we can discuss the installation scope.

Sewer Line Installation

Underground sewer line installation for new homes, development sites and commercial sitework. We review the proposed utility layout and project requirements with you before estimating the work.

Storm Drainage Systems

Storm drainage installation to support runoff management across your property or construction site. Coordinate underground drainage with excavation and grading as part of your sitework plan.

Planning a new home, a multi-acre residential development or a commercial construction site? Stone Pro Grading can discuss water lines, sewer lines and storm drainage as part of your sitework scope. We serve Waxhaw, Union County, Charlotte and nearby communities, including Monroe and Weddington.

Provide your project location, approximate acreage, available plans, utility needs and desired construction timeline. We will review the scope with you and discuss how underground installation fits alongside excavation, grading and drainage work.

Water Line Scope: What to Review Before Installation

A water line project starts with a simple question: where does the line begin, and where does it need to end? Plans that show the service point, the building or fixture locations and the route between them let us discuss trenching, access and grading in concrete terms. On larger sites, the plan may also show several branches, so each segment can be reviewed in the order it will be built.

Water lines cross driveways, walks and landscaped areas, so note which surfaces already exist and which are still to be built. A line placed before paving is a different task from one placed beneath finished pavement, and the scope should say which applies. Also mention areas that must stay undisturbed, such as retained trees or finished lawns, so the route can be reviewed around them.

Sewer Line Scope: Layout, Grades and Connection Points

Sewer lines depend heavily on the elevations around them, so the proposed layout and the grading plan should be read together. Identify where the line leaves each structure, where it is expected to connect and what the drawings show for slopes along the way. If the plans leave questions open, listing them early is more useful than discovering them in the trench.

Whether sewer service is available at a property, and how a connection is made, is a matter to confirm with the property's service provider. Bring that information to the conversation, along with any notes about structures, easements or neighboring lines that may affect the route.

Storm Drain Scope: Where Runoff Is Meant to Go

Underground storm drain installation carries runoff from the places it collects to the places the plans send it. To review that work, we look at the drainage layout, the finished grades around inlets and the point where water leaves the site. A drain that is installed correctly can still underperform if the surrounding grades do not direct water toward it, which is why storm drain work is best reviewed together with grading. For above-ground drainage and erosion control, see our storm drainage services page.

Service Availability and the Plans to Supply

Utility availability varies by property, and a community name or mailing address does not settle it. Confirm the actual provider and the available connections for your parcel before the scope is fixed. When you contact us, the following help us review the work:

• The full property address and approximate acreage
• Site plans or utility drawings showing proposed water, sewer and storm routes
• Planned grades, pad locations and building footprints
• What you know about service availability and connection points
• Your target start date and any phasing

If your plans are still in draft, send them anyway and mark what may change.

New Construction Versus Work on an Existing Property

On a new construction site, lines are usually placed while the ground is open, before paving, landscaping and finished grades. Access is easier and conflicts are mostly with other planned work. On an existing property, new lines must fit among structures, pavement, trees and existing utilities that stay in use. The scope there depends on what is already in place, where equipment can reach and what must be restored afterward.

Tell us which description fits your project, and share photos of the area where work is expected. Records of existing lines are useful, but they may not show everything that is actually in the ground, so the scope should allow for conditions to be confirmed as work proceeds.

Coordinating With Clearing, Grading and Excavation

Underground work rarely stands alone. Clearing sets the limits of the disturbed area, grading sets the elevations lines must respect, and excavation opens the trenches. Reviewing these together can reduce repeated passes over the same ground. Visit our land clearing, excavation services and site preparation pages to see how these pieces fit together.

Access and Surface-Restoration Boundaries

Trenching changes the ground, and it helps to agree beforehand how far that change extends. Define the working corridor along each route, the points where equipment may enter, and any surfaces that must stay usable. Then describe the condition each disturbed area should be left in and who handles finished surfaces afterward.

Points worth settling early

• Which drives, walks or entrances need to remain open during work
• Where excavated material can be placed while trenches are open
• Whether pavement, base or landscaping follows and when
• Which areas are off limits to equipment

Bid Checklist for Underground Utility Work

General contractors and developers assembling bids can use this list to keep requests consistent:

• Which of the three systems, water, sewer and storm, are in scope
• Plan revision date and a note of any pending changes
• Connection points and what is confirmed with the provider
• Order in which areas are released for work
• Access, staging and delivery constraints
• Restoration boundaries and what follows our work

Underground Utilities Questions

Which utilities can you install?

We install underground water lines, sewer lines and storm drains, along with the excavation and grading around them.

How do I know if service is available at my property?

Check with the property's service provider. Availability depends on the individual parcel, so bring what you learn to the scope discussion.

Should utility work happen before or after grading?

The order depends on your plans and the surfaces involved. Reviewing grading and trenching together helps avoid cutting into finished work.

Can you work on a property that is already built?

Existing properties can be reviewed too. Share photos, any records of existing lines and a description of surfaces to be protected or restored.

What if my plans are not final?

Send the current set and mark open items. The scope can be discussed on that basis and refined as drawings are completed.
