Illustrative format example

This entry demonstrates the case-study structure. It is not a record of a specific C-Water project, and contains no customer names or performance figures.

01The challenge

What Was Wrong.

A plant treats all process water to a single high standard because that is what the original specification said. Nobody currently working there knows where the specification came from or which process step it was written for.

02The existing system

What Was There.

A single treatment train feeding several process uses with different requirements. Every litre is treated to the standard of the most demanding step, including the water used for the least demanding.

03What C-Water did

The Approach.

  1. 01

    Map demand against requirement

    Each point of use is listed with the parameters it genuinely cares about and the tolerance around each. This is usually the first time the site has seen that comparison written down.

  2. 02

    Characterise the source across a year

    A single sample on a good day describes a good day. The design has to hold across the range the supply actually delivers, including its seasonal worst.

  3. 03

    Consider segregation

    Where demands differ significantly, treating separate streams to separate standards can cost less to run than treating everything to the highest one.

  4. 04

    Verify at the point of use

    Online measurement at the point of use confirms the specification is being met when production needs it — not on average, and not at the plant outlet.

04What it addresses

The Outcome.

A specification that can be explained

Each requirement traces to a process reason, which makes it possible to review it when the process changes.

Over-treatment becomes visible

Treating to a higher standard than the process requires is a permanent operating cost, and it is invisible until the requirement is written down.

Verification where it counts

Measuring at the point of use rather than at the plant outlet is what turns a specification into evidence.

The insight

Inherited specifications are among the most expensive documents in a plant. They are rarely wrong in a way that causes a failure, which is exactly why nobody revisits them.
