A water conversation often begins with a volume request and ends with a supply letter. Between those points sits the actual campus water system: source, treatment, pressure, storage, cooling, discharge and the facilities needed to connect them. A provider may be willing to serve while one of those elements remains unfunded or incompatible with the proposed campus. Solving the request is not the same as solving the system.
The campus problem
Illustrative scenario, not a claimed client result.
A funded North Texas campus has a preferred cooling design but no complete water solution. A provider has discussed supply, while treatment, peak demand, drought conditions and wastewater responsibilities remain open. The sponsor is being asked to commit to a layout that may depend on infrastructure outside its control. The assignment is to develop and deliver a supportable water-and-cooling pathway for the first phase.
The constraint can move when the cooling design changes
Annual consumption is not enough to size or contract the service. The team needs the relevant peak demand, seasonal operating conditions, water-quality requirements and wastewater characteristics. A design with lower routine consumption may have different electrical demand, footprint or capital cost. Reuse may reduce one supply requirement while adding treatment, storage or distribution infrastructure. Those tradeoffs should be evaluated together rather than passed between separate water and power workstreams.
The provider's constraint also needs to be named precisely. It may be source availability, treatment capacity, distribution pressure, a missing transmission main or limited wastewater acceptance. Paying for a new main does not resolve a treatment bottleneck. Increasing storage can help with a defined short-duration mismatch, but cannot create a sustained source that is absent. The technical solution should follow the bottleneck rather than the asset the campus is most ready to buy.
What is happening
TRWD’s July 27, 2026 FAQ says data center requests need justified volumes and conservation information for evaluation. It also distinguishes raw-water supply from treatment and local development approvals. A discussion with one provider does not settle the whole campus water pathway.
Do not fund the same future capacity twice
A provider may include a regional increment while the campus budget separately carries an oversized private asset. Reconcile both against a single phase-demand basis, with distinct allocations to campus and public beneficiaries. Test a delayed tenant, an unavailable reuse source and a change from the initial cooling design. A smaller funded first phase with a reserved expansion route can be better than a nominally complete regional concept without an operator or debt-service plan.
Enough annual water, but no acceptable peak-day service
Consider a hypothetical opening phase with 0.50 million gallons per day (MGD) of normal total makeup demand and 0.80 MGD during a three-day hot-weather event. Assume the provider supports 0.65 MGD at the required quality and pressure throughout that event. A separate process-water tank has 0.60 million gallons of usable inventory above protected fire and operating reserves. These are teaching assumptions, not cooling benchmarks, provider commitments or design criteria.
The peak deficit is 0.15 MGD. Three days consume 0.45 million gallons, leaving 0.15 million gallons above protected reserve. Four consecutive peak days exhaust the usable buffer. At normal demand, the 0.15 MGD refill margin takes three days to restore the 0.45 million gallons used. A second heat event before recovery changes the answer. Storage solves a defined duration problem; it does not create a sustainable supply increment.
Now add a different constraint: assume peak discharge is 0.18 MGD but the receiving utility has accepted only 0.15 MGD. The supply-and-storage calculation passes the three-day event while the overall service fails by 0.03 MGD on discharge. Quality limits, instantaneous flows and pretreatment could constrain it further. The opening configuration cannot be approved from the supply calculation alone.
The comparison below tests four responses against that same service boundary. A smaller first phase is the only immediately feasible route under the assumed conditions. A lower-water cooling alternative looks attractive until its additional 2 MW of peak facility demand is compared with just 1 MW of available electrical headroom. Reclaimed water reduces freshwater demand but does not, by itself, resolve discharge. Expanding both supply and discharge can work later if the provider accepts the works and the tenant can wait.
The development decision is therefore to offer the smaller phase while preserving expansion rights, not to buy a larger tank and call the water issue closed. That recommendation reverses if the tenant cannot use the smaller phase, if the hot-weather event lasts longer, or if an accepted power or wastewater upgrade changes the limiting system. Before release, the owner needs a signed phase service basis that states supply, water quality, peak duration, recovery, discharge conditions and who pays for the next increment.
Solutions and their tradeoffs
Use the proposed supply and cooling system
The provider can support the demand and the required connections can be delivered.
Conditions to resolve: Written service conditions, treatment responsibility, connection design and discharge acceptance.
Change cooling or add reuse
A technically acceptable option reduces the binding supply constraint.
Conditions to resolve: Operator acceptance of heat rejection, energy use, water quality, maintenance and whole-life cost.
Reduce or relocate the first phase
No feasible system supports the original opening brief.
Conditions to resolve: Commercial impact of reduced capacity versus the cost and timing of a new supply route.
Four routes tested against the same opening phase
Hypothetical operating values. MGD means million gallons per day. Designers and providers must establish simultaneous peak conditions; none of these figures is a Texas regulatory limit.

| Route | Assumed peak makeup / discharge | Constraint remaining | Decision |
|---|---|---|---|
| Stage the initial tenant load | 0.60 / 0.14 MGD | Tenant must accept the reduced opening load; confirm quality and pressure | Advance only with an accepted smaller operating envelope. |
| Change cooling design | 0.45 / 0.10 MGD | Adds 2 MW at peak; only 1 MW is available | Hold until electrical headroom or the cooling design changes. |
| Use reclaimed makeup | 0.35 fresh + 0.45 reclaimed / 0.20 MGD | Discharge exceeds accepted 0.15 MGD by 0.05 MGD | Do not advance on freshwater savings alone. |
| Expand provider systems | Support 1.00 MGD supply and 0.25 MGD discharge | Assume 18 months to accepted service, beyond opening | Preserve the route for expansion; rephase if needed now. |
This is the development problem behind our water solution blocked challenge. Our Water & cooling capability explains the scope Sitebraid can take on.
Putting the analysis to work
We would start with the operator’s environmental operating envelope and the designer’s water balance, not a single annual consumption estimate. The design team should identify average and peak make-up, seasonal demand, commissioning fill, water-quality requirements, treatment losses and discharge characteristics. Fire protection and domestic service need their own design checks. We would then compare those requirements with the actual provider boundary, service conditions and proposed connection points.
How Sitebraid would support this decision
Build one demand case
Convene the operator, cooling designer and civil team to resolve inconsistent assumptions. Give each provider a justified demand profile and distinguish opening-phase needs from future reservations. Keep the calculation traceable when the IT or cooling design changes.
Resolve the complete service chain
Identify who supplies raw or treated water, who treats it where needed, who owns storage and pumps, and who accepts wastewater. Examine reclaimed-water or other alternatives only after the specialists establish availability, rights, quality and treatment requirements. A well is an option to investigate, not an assumed exemption from supply or permitting constraints.
Develop the selected route
Coordinate the necessary studies, easements, agreements and design packages. Establish ownership, funding and operation of off-site improvements. Bring storage, connection works and temporary commissioning needs into the schedule. Align public commitments with the selected, budgeted design.
Build and prove the system
Follow the retained contractors through construction, inspections and commissioning. Require the testing specified by the designers and providers. Confirm the operator has the operating procedures, maintenance obligations and approved response to supply restrictions before the phase is accepted.
How we protect the decision
The owner needs a side-by-side decision on capital cost, ongoing energy and water cost, delivery timing and operational limitations. Lower water use is not a complete recommendation if it creates an unacceptable electrical or heat-rejection requirement. We would require operator sign-off on the selected basis and a change-control check whenever cooling density, phase size or the supply arrangement changes.
The result the owner should require
An accepted water solution means more than an agreement to discuss supply. For readiness, require the agreed service pathway, assigned infrastructure scope and necessary permissions for the contracted stage. For delivery, require completed connections and the specified performance and quality evidence, including the wastewater interface. Acceptance is against the project brief, not a generic claim of water independence.
How to measure progress
- Provider-confirmed service conditions compared with phase demand.
- Unassigned supply, treatment, storage and discharge responsibilities.
- Cooling-design changes affecting electrical demand or the layout.
- Completed infrastructure and test records required for phase acceptance.
The decision to take forward
Release the first phase against the limiting combination of supply, peak duration, recovery, discharge and electrical headroom. In the worked case, reduce the opening envelope and preserve an accepted upgrade route. Change that decision only when new technical and provider evidence removes the actual bottleneck, not when a water-saving technology looks attractive in isolation.
