A promising development site needs more than nearby water and wastewater infrastructure. Communities also need to know what those systems can serve, under which conditions, and when.

Can your water and wastewater systems support the development your community wants to encourage?

For local leaders, that question connects housing priorities, commercial development, and industrial recruitment to infrastructure decisions. A property may have a water main or wastewater outfall nearby and still lack the pressure, fire flow, collection capacity, or available treatment capacity required for its intended use. Proximity is an initial screening question, not proof of site readiness.

North Carolina’s statewide water and wastewater infrastructure master plan connects long-term utility viability with economic development. The Economic Development Partnership of North Carolina’s Certified Sites program considers utility information alongside other development factors. Similar questions matter in South Carolina and Georgia, although local utility policies and state requirements differ.

Move From Utilities Identified to Utilities Verified

Early site screening often starts by identifying nearby water and wastewater lines. The next questions are more consequential: What capacity is available at the appropriate connection point? How is capacity allocated? Can the network maintain adequate pressure and fire flow? Who pays for extensions or improvements? Depending on the proposed use, electric, natural gas, and fiber service may also shape feasibility.

A practical evaluation moves through three stages: utilities identified, utilities quantified, and utilities verified. Identifying infrastructure establishes what exists. Quantifying service considers expected demand, capacity, operating conditions, and improvement needs. Verification tests those findings against the proposed development and applicable utility requirements.

Available treatment capacity alone cannot establish that pipes, pump stations, storage facilities, and other assets can serve a specific property. Utility teams should assess location, intended use, anticipated demand, existing commitments, and timing against adopted performance criteria, including pressure, fire flow, wet-weather performance, and system utilization.

Reliable conclusions also require a structured evaluation process. Accurate asset inventories, operating records, monitoring, and calibrated hydraulic models help establish how a system actually performs. A model supports decisions only to the extent that its data, calibration, and assumptions reflect current conditions.

Separate an Evaluation From a Service Commitment

When communicating with a developer or site selector, distinguish an engineering finding from a utility policy decision or formal assurance:

A favorable evaluation is not a reservation, and planned future capacity is not available service. Any readiness statement should explain whether service is currently supported, depends on identified improvements, or relies on a planned project. Conditions and limitations should be documented rather than implied.

Reconcile Three Different Definitions of Readiness

Economic development, planning, and utility teams may look at the same site through different lenses. Economic development asks whether it is competitive and credible to submit to a prospect today. Planning asks whether the proposed type and intensity of development align with community priorities and land-use policy. Utilities ask what infrastructure can serve, where it can connect, and which improvements are funded or programmed.

Each group can answer its own question accurately while the community still reaches an incomplete conclusion about readiness. Bring these perspectives together before marketing a site. A credible determination accounts for economic feasibility, community priorities, and the practical limits of infrastructure.

Shared maps and analyses can help. Geographic information systems (GIS) can connect priority sites, utility assets, and land-use information. Hydraulic modeling can test projected demands against service criteria. Asset management and lifecycle planning help identify the investments needed to sustain service for existing and future customers.

Explain the Path to Service, Not Just a Target Date

If service depends on improvements, identify what must happen before it becomes available. This may include planning, design, funding, permits, easements, construction, testing, and bringing facilities into operation. Explain who is responsible for the work and what costs or developer obligations remain unresolved.

Future capacity assessments should reflect adopted utility performance indicators, projected growth, existing commitments, and identified infrastructure improvements. Communities can use those criteria to estimate costs, prioritize capital projects, and explain why a connection may be feasible only after specific work is completed.

Early schedules are planning estimates, not guarantees. State the assumptions, milestones, and decisions that could change service availability. A proposed expansion or funding application should never be presented as a firm commitment.

Start With a Shared Review of Priority Sites

Bring economic development, planning, utilities, and finance staff together to review a manageable group of priority sites or growth areas. Include the service provider if it is a separate organization. For each location, document the intended use, demand assumptions, known constraints, current evaluation status, possible improvements, preliminary costs, and outstanding funding or policy decisions.

Assign responsibility for updating those findings and approving external descriptions of readiness. Date each assessment and revisit it when system conditions, demand forecasts, development plans, or project schedules change. The goal is one current explanation that staff can communicate consistently and confidently.

Turn Technical Findings Into Practical Decisions

WithersRavenel’s water and wastewater engineering, GIS, and utility asset management services help communities evaluate infrastructure needs and connect technical findings with development and capital planning. The objective is to see capacity before it becomes a constraint, then use that understanding to prioritize investments and communicate realistic service expectations.
