Boost Construction Success: Engage Early and Often

Developers and owners are actively bringing general contractors, construction managers and subcontractors into projects earlier than before.

Their reasoning is simple: tap into practical expertise before constructability issues arise, as well as resource constraints or environmental challenges, which can drive up costs or delay completion.

Often, those early decisions include evaluating where exactly a facility should be built.

When offering input on site selection, teams have traditionally focused on labor availability, raw material costs and supply chain access. But water availability, quality and long-term reliability has become a major factor, especially in water-scarce regions.

This is prompting many companies to integrate water reuse strategies into their planning. At the same time, organizations must balance these decisions with sustainability goals, lower carbon emissions, and in some cases, regional pressure to achieve zero liquid discharge.

Contractors and construction managers are well positioned to guide clients through these challenges. By incorporating advanced treatment technologies, recycling systems and energy‑efficient processes, experts can help cut freshwater use, reduce environmental impacts and lessen water-treatment emissions.

Not all water needs to be treated equally. Water quality parameters, such as salinity, hardness and temperature, directly influence how water can be used and how extensively it must be treated.

For example, water that’s acceptable for drinking may work in cooling systems, but typically falls short of the purity required for boiler makeup. Conversely, using high‑purity water where it isn’t necessary wastes resources.

That is why “fit for purpose” treatment has become essential. With this approach, only the absolute necessary water quality is achieved, because treating water beyond that threshold can unnecessarily increase carbon dioxide (CO₂) emissions, energy use and overall cost.

Allocating treatment efforts more strategically allows owners to meet operational needs, while still supporting sustainability targets.

A constant consideration in industrial planning is the water-energy nexus: the intertwined relationship between the water required to produce energy and the energy required to extract, treat and distribute said water. The problem is that finding the right balance often involves complicated tradeoffs.

For instance, look at advanced treatment systems like reverse osmosis (RO). While RO provides high‑purity water suitable for reuse or direct discharge, it typically demands more electricity than alternative technologies. It is an issue that’s especially stark when it comes to data centers.

Water is an excellent heat‑transfer medium, and in industrial settings, evaporative cooling is among the most efficient ways to remove heat from processes with large thermal loads. Data centers — particularly those supporting artificial intelligence — produce intense heat in compact spaces.

Cooling water systems can efficiently remove this heat while also helping operators reduce power usage effectiveness (PUE). More specifically, achieving a PUE approaching 1.0 is not feasible with air cooling alone, and as such, water‑ or liquid‑based cooling is necessary.

Sustainability goals increasingly require owners to compare treatment technologies using consistent metrics. For example, choosing between ion exchange (IX) and RO for demineralized water production involves comparing tradeoffs:

• RO consumes more energy on average due to higher operating pressure, leading to a larger CO₂ footprint.
• IX requires chemical regeneration, commonly sodium hydroxide and hydrochloric acid, which carries its own embodied carbon emissions.

Completing a mass and energy balance for each option enables a true, apples‑to‑apples comparison to evaluate which technology delivers the lowest CO₂ impact over the system’s lifetime.

Sludge management is another area where emissions differ widely. Although equipment like brine concentrators or sludge dryers consume energy, their total CO₂ footprint is often lower than repeatedly hauling large volumes of residual waste for off‑site disposal.

Again, mass and energy balances offer essential insight.

No single treatment technology is universally superior, and overall performance depends entirely on the application. A system that is energy‑efficient and low‑emission in one setting may be impractical or carbon‑intensive in another.

This is where multidisciplinary expertise becomes invaluable. Consultants with broad knowledge of treatment technologies, system integration and operational priorities can help identify which combination of solutions best aligns with project targets. Their evaluations consider not only technical performance, but also long‑term sustainability, operational reliability and the carbon footprint tied to construction and operation.

By grounding water strategy decisions in data, context and the principles of the water-energy nexus, companies can select technologies that meet operational needs, protect resources and support their sustainability commitments, while remaining ahead of evolving industry and regulatory expectations.
