Before a proposed water and sewer layout is locked into a site plan, the project team should confirm four things with Charlotte Water and document them in writing: current service availability at the specific parcel, the connection application and review path that applies to the project type, the responsibilities and named owner for each phase of connection installation, and the field conditions that could conflict with the proposed route. Charlotte Water connection planning is not complete just because a water main appears on a GIS layer near the property. Availability, capacity, easement access, and installation responsibility all have to be confirmed through the current published process before the layout is treated as final.
This article summarizes what Charlotte Water's public pages describe about new connection installations and the current design manual, and it adds practical coordination guidance that Cooper Development Group uses when reviewing a project's utility plan. The published requirements and the practical guidance are labeled separately throughout. Charlotte Water's requirements, forms, and design standards can change, and only Charlotte Water and the authority having jurisdiction can confirm what applies to a specific parcel, connection type, and submittal date. Nothing in this article should be treated as a substitute for that confirmation, and it does not state or imply any approval timeline, inspection result, or cost for any project.
What Charlotte Water's Current Public Sources Establish
Charlotte Water publishes a New Connection Installations page that describes the process for commercial development connections, and it maintains a design manual that sets out the technical standards development teams are expected to follow when designing water and sewer infrastructure. These two published resources are the starting point for any Charlotte Water connection planning effort, because they represent what the utility has stated publicly about how connections are supposed to be requested, reviewed, and installed.
The New Connection Installations page addresses the administrative side of getting a connection: who initiates the request, what happens after a request is submitted, and where responsibility sits at different points in the process. The design manual addresses the technical side: the standards a proposed layout has to meet before Charlotte Water will treat it as an acceptable basis for construction. A project team that has only looked at one of these two resources has not yet completed a full review, because availability and technical conformance are separate questions that both have to be answered.
Both pages are maintained by Charlotte Water and are subject to revision. The version of the design manual referenced during early planning may not be the version in effect when construction documents are finalized. Confirming the current version and current process directly with Charlotte Water, rather than relying on a prior project's experience, is part of a defensible Charlotte Water connection planning approach.
- Charlotte Water's New Connection Installations page addresses how commercial connection requests are initiated and processed.
- Charlotte Water's design manual sets the technical standards a proposed water and sewer layout must meet.
- Both resources are subject to revision, and the current version should be confirmed directly with Charlotte Water before a layout is finalized.
Inputs and Existing Conditions to Document Before Layout Decisions
A proposed water and sewer layout is only as reliable as the existing-conditions information behind it. Before a project team fixes a route on paper, there are several categories of information that should be documented, not assumed. This documentation step is where many later coordination problems originate, because a layout drawn against incomplete information can look correct on a site plan while still conflicting with what actually exists in the ground or with what Charlotte Water will approve.
At minimum, a project team should be documenting the location and size of the nearest available water main and sewer main, any known capacity constraints in that service area, existing easements that cross or border the parcel, other utility conflicts along the proposed route, and the ownership status of any existing service laterals. Where any of this information comes from a source other than Charlotte Water directly, such as a prior survey or a neighboring project's record drawings, that information should be treated as a starting point for verification rather than as a confirmed fact.
Documenting existing conditions also means recording where information is missing. If capacity data for a service area has not been confirmed, that gap should be tracked as an open item rather than assumed favorable. A layout that depends on an unconfirmed assumption is not yet a buildable plan.
- Confirm the location and size of the nearest water and sewer mains directly with Charlotte Water rather than relying solely on GIS or third-party mapping.
- Identify any known capacity constraints in the service area before assuming a connection is available as proposed.
- Record existing easements, other utility crossings, and any existing service laterals on the parcel.
- Track any information gap as an open item requiring verification, not as a favorable assumption.
A Step-by-Step Review for the Owner and Project Team
Before treating a proposed water and sewer layout as final, an owner and project team can work through a sequence of checkpoints. This sequence does not replace Charlotte Water's own review process, but it gives the project team a way to organize what needs to be confirmed and in what order, so that design effort is not spent finalizing a layout that later has to be redrawn.
The first checkpoint is availability. This means confirming with Charlotte Water that a connection of the proposed type and size is available at the point on the parcel where the layout assumes it will connect. The second checkpoint is the application path. Different project types and connection types may follow different submittal and review steps, and the project team should confirm which path applies before assuming a generic timeline or process. The third checkpoint is plan conformance, meaning a check of the proposed layout against the current design manual standards for pipe sizing, materials, separation, and other technical criteria. The fourth checkpoint is responsibility assignment, confirming in writing who is responsible for each piece of the connection installation. The fifth checkpoint is field verification, confirming that what is shown on the drawings matches what is actually present at the site.
Each of these checkpoints can surface information that changes the layout. Treating them as a sequence, rather than as parallel tasks handled informally, reduces the chance that a change discovered late in one area forces rework across the whole site plan.
- Confirm availability of the specific connection type and size at the proposed location directly with Charlotte Water.
- Confirm which application and review path applies to the project before assuming a generic process.
- Check the proposed layout against the current design manual standards for sizing, materials, and separation.
- Assign and document responsibility for each phase of the connection installation.
- Verify field conditions against the drawings before construction begins.
Responsibilities, Dependencies, and Hold Points
A recurring source of delay on development projects is not the technical design itself, but unclear responsibility for who does what and when. Water and sewer connection work typically involves multiple parties: the property owner, the design engineer, the general contractor, any utility subcontractor, and Charlotte Water. Charlotte Water connection planning benefits from naming, in writing, which party is responsible for each task before construction sequencing is finalized.
Some tasks depend on others being completed first. A connection application generally cannot be meaningfully submitted until the proposed layout has been checked against current design standards. Installation cannot reasonably proceed until responsibility for tie-ins, testing, and any required inspections has been assigned. Where a task depends on another task's completion, that dependency should be identified as a hold point, meaning work should not proceed past that point until the prior item is confirmed.
This coordination is not something Charlotte Water assigns for a project team. Charlotte Water's published materials describe the utility's own process; they do not assign internal responsibility among the owner, engineer, and contractor. That assignment is the project team's task, and it should be documented in the same coordination matrix used to track other utility items, not left as an informal understanding between parties.
- Name a specific responsible party for each connection-related task rather than leaving responsibility implied.
- Identify which tasks depend on completion of another task and treat those dependencies as hold points.
- Document responsibility assignments in writing rather than relying on informal understanding between parties.
- Remember that Charlotte Water's published process describes the utility's own review steps, not internal project team responsibility.
Common Coordination Failures Worth Watching For
Several patterns show up repeatedly when a water and sewer layout is finalized before it has been fully checked. Recognizing these patterns in advance gives a project team a chance to catch them before they become expensive to correct.
One common pattern is treating a mapped utility line as confirmed availability without direct verification. A line shown on a map does not by itself confirm size, capacity, or that a connection at that point will be approved. Another pattern is assuming a single application path applies to every connection type, when Charlotte Water's process may differ depending on the nature of the project and the connection requested. A third pattern is finalizing a layout before checking it against the current design manual, only to find later that the manual has been updated since the layout was drawn. A fourth pattern is leaving responsibility for a specific installation task unassigned until a dispute arises about who was supposed to handle it.
A fifth pattern worth naming is skipping field verification because the drawings appear complete. Existing conditions in the ground do not always match record drawings, and a layout that looks correct on paper can still encounter a conflict that was never documented. None of these patterns are unusual on development projects, which is why building a deliberate checklist into the Charlotte Water connection planning process, rather than relying on informal review, is a reasonable practice for an owner to expect.
- Do not treat a mapped utility line as confirmed availability without direct verification from Charlotte Water.
- Confirm which application path applies to the specific connection type rather than assuming one process fits all projects.
- Check the layout against the current design manual before finalizing it, not after.
- Assign responsibility for each installation task in writing before a dispute forces the issue.
- Verify field conditions on site rather than relying solely on record drawings.
Questions to Bring to Charlotte Water or a Qualified Professional
Because Charlotte Water's requirements and design manual are maintained and updated by the utility, and because every parcel has its own existing conditions, a project team should bring specific questions to Charlotte Water or to a qualified design professional before treating any layout as final. These questions are meant to prompt direct verification, not to be answered from a general article.
Useful questions include whether the proposed connection size and location are currently available at the parcel, which application and review path applies to the specific project type, whether the current version of the design manual has any provisions that affect the proposed layout, who is expected to install versus inspect each portion of the connection, and what field conditions Charlotte Water or the design professional would want confirmed before construction begins. An owner who brings these questions to the responsible authority early is in a stronger position than one who waits until a permit or inspection stage to ask them.
Any code, environmental, health, or engineering question that arises during this review should be directed to the authority having jurisdiction or to a licensed professional in that field. Cooper Development Group's role in this kind of pre-construction planning is coordination and documentation support, not the issuance of code or engineering determinations.
- Ask Charlotte Water directly whether the proposed connection size and location are currently available.
- Ask which application and review path applies to the specific connection and project type.
- Ask whether the current design manual version affects the proposed layout in any way.
- Ask who is expected to install and who is expected to inspect each portion of the connection.
- Direct any code, environmental, health, or engineering question to the authority having jurisdiction or a licensed professional.
Next Steps for an Owner Working Through This Checklist
A proposed water and sewer layout is a working draft until availability, application path, design conformance, responsibility, and field conditions have all been confirmed against current, published information. Locking a layout before completing that review increases the chance of rework later in the project. Working through the checklist described in this article, and documenting the answers in writing, gives an owner a clearer record to point back to if questions come up during permitting or construction.
Cooper Development Group works with owners on pre-construction planning and coordination for development projects, including organizing the kind of utility review checklist described here. This article does not describe a specific project, cost, or timeline, and any project-specific requirement should still be confirmed with Charlotte Water and the authority having jurisdiction before design decisions are finalized. Readers who want background on how utility and site infrastructure coordination fits into a broader project can review the infrastructure and building systems overview page, and additional planning topics are available on the CDG blog.
An owner who wants to talk through how this checklist applies to a specific parcel or project can reach out through the consultation page to start that conversation. That conversation is a planning discussion, not a substitute for Charlotte Water's own review or for any required professional design and permitting work.
- Treat a proposed layout as a draft until availability, application path, design conformance, responsibility, and field verification have all been documented.
- Keep written records of each confirmation so they can be referenced during permitting and construction.

Questions homeowners ask
Is a utility line shown on a map the same as confirmed water or sewer availability?
No. A line shown on a map or GIS layer indicates that infrastructure exists nearby, but it does not confirm size, capacity, or that a connection at a specific point will be approved. Charlotte Water connection planning should include direct confirmation from Charlotte Water about availability at the specific parcel and connection point, not reliance on mapped data alone.
Who decides the application and review path for a new connection?
Charlotte Water's published process describes how commercial connection requests are handled, and the applicable path can depend on the project type and the connection requested. The specific path for a given project should be confirmed directly with Charlotte Water rather than assumed from a general description or from a different project's experience.
Does Charlotte Water assign responsibility between the owner, engineer, and contractor for installation tasks?
Charlotte Water's public materials describe the utility's own review and connection process. They do not assign internal responsibility among the owner, design engineer, and contractor for tasks like tie-ins, testing, or field verification. That assignment is the project team's responsibility and should be documented in writing as part of pre-construction planning.
Why does field verification matter if the design drawings already show the proposed layout?
Existing conditions in the ground do not always match record drawings or GIS data. Field verification checks the proposed layout against what is actually present at the site, which can reveal conflicts with other utilities, easements, or existing laterals that were not visible on paper. Skipping this step increases the risk of discovering a conflict after construction has started.
How often does the Charlotte Water design manual change, and how should a project team track that?
Charlotte Water maintains and updates its design manual, and the version in effect can change between early planning and final construction documents. A project team should confirm the current version directly with Charlotte Water before finalizing a layout, rather than relying on the version referenced earlier in the project.
