A New Tool for Evaluating Water Risk in Supply Chain Planning

In developing a supply chain network design there are many criteria to consider – including such factors as the impact of the facility choices on
• Cost of running the system,
• current and future customer service,
• ability to respond to changes in the market, and
• risk of costly intangible events in the future
to name a few.

Frequently we use models to estimate revenues / costs for a given facility footprint, looking at costs of production, transportation, raw materials and other relevant components. We also sometimes constrain the models to ensure that other criteria are addressed – a constraint requiring that DCs be placed so that 80% of demand be within a day’s drive of a facility, for instance, might be a proxy for “good customer service”.

Some intangibles, such as political risk associated with establishing / maintaining a facility in a particular location, are difficult to measure and include in a trade off with model cost estimates. Another intangible of great interest for many companies, and that has been difficult to make tangible, is water risk. Will water be available in the required quantities in the future, and if so, will the cost allow the company to remain competitive? For many industry groups water is the most basic of raw materials involved in production, and it is important to trade off water risk against other concerns.

As I wrote in a previous blog published in this forum,

There are several risks that all companies face, to varying degrees, as global water consumption increases, including
• Physical supply risk: will fresh water always be available in the required quantities for your operations?
• Corporate image risk: your corporate image will likely take a hit if you are called out as a “polluter” or “water waster”
• Governmental interference risk: governmental bodies are becoming increasingly interested in water consumption, and can impose regulations that can be difficult to deal with
• Profit risk: all of the above risks can translate to a deterioration of your bottom line.

The challenge has been: how to quantify such risks so that they can be used to compare network design options.

Recently a post entitled “How Much is Water Worth” on LinkedIn highlighted a website developed by Ecolab that offers users an approach to monetization of water risks. This website allows the user to enter information about their current or potential supply chain footprint – such as locations of facilities and current or planned water consumption – and the website combines this information with internal information about projected GDP growth for the country of interest, the political climate and other factors to calculate a projected risk-adjusted cost of water over the time horizon of interest.

This capability, in conjunction with traditional supply chain modeling methods, gives the planner a tool that can be used to develop a more robust set of information that can be used in decision-making.
