The subject of water pressurization is quite complex and the description is very simple. If a point of exit, be it a household tap or a fire hydrant does not give pressure when opened it means that the source of supply does not give sufficient "head" to give a reasonable supply pressure. Obvious! certainly, but it becomes complex when you feed in factors such as the supply is OK between 01:00 hrs and 07:00 hrs. Another example is when a factory, office block or a processing complex receives a good supply at the point of entry but finds that there is insufficient water to refill a toilet cistern at the extremes of the premises!. What can be done?. You can increase the size of all pipes, fittings and valves between the water source, it may solve the problem at great expense or it may not.
We as a company have been solving many of these situations for many years e.g. A large caravan holiday park in East Anglia suffered a poor supply during holiday peak periods, not due to the extreme use on the particular site but generally due to the high holiday population over the area demanding above average water supplies. The whole project was overseen by the clients consultants with the civil contractor providing ground work services.
The Installation involved taking the existing supply from the mains and feeding the water via ball cocks to four 5000 litre specially constructed tanks suitable for storage of potable water. The valving and pipework from each tank was arranged in such a way that no cross-contamination could take place and fed to a common supply pipe. A Twin Automatic Booster Pump system was installed complete with a 200ltr accumulator tank in a plant room. Pressure control to two outlets to the site requiring different pressures is controlled by manually adjustable reducing valves from a system working pressure of 60 psi.
