8 THE COMPONENTS USED

IN BOOSTED (PUMPED) COLD
WATER SUPPLY SYSTEMS FROM

PRIVATE SOURCES FOR SINGLE-
OCCUPANCY DWELLINGS

In this, the final part of the unit dealing with private water supplies, we will
investigate the components used with private water supplies to single domestic
dwellings:
1 small booster pump sets, which incorporate all controls and components
2 boosted system with separate controls and components
3 use of accumulators in increasing system flow rate.

Vertical, horizontal and submersible

pumps
There are two different types of pump that can be used with private water
supplies and, more specifically, boreholes and springs:

1 surface pumps, such as:
● horizontal single-stage types
● vertical multi-stage types
2 submersible pumps.
Surface pumps for private water supplies are available either as single
components or as packaged units containing all the necessary equipment
pre-fitted. The latter are the easiest to install and require only the final
plumbing and electrical connections.
