Modern water equipment typically requires at least 2.0 bar pressure for effective operation.  Most water companies will only guarantee 1.0 bar at ground level.

Some water companies are delivering good pressure for much of the time.  However seven day pressure test will show that pressure can fall below an acceptable level at peak times.

Even if  the seven day test shows a good maintained pressure, the water companies 1.0 bar guarantee will allow them to reduce pressure at any time.

The answer to the above question is that if you want to safeguard your company against claims arising from plumbing equipment not working because of poor water pressure, then you need to consider a boosted pressurisation system on all projects.
