Fountain Structure Designs & Structural Variations

This section deals with the most frequent and important variations of the fountain structure. It does not lay claim to completeness or degree of urgency. It's intention rather is to illustrate various methods of achieving the objective so that the most suitable forthe respective case can be selected. The illustrations are for the purpose of guidance only. In view of the complexities of design and construction of water retaining structures, this is best left to the experts. Only they can provide the data and design advices regarding foundations, reinforcement, weathering qualities, frost resistance, material selection etc.
The planning of fountain hydraulics and engineering belongs In the hands of the experts and should be left to those who have been trained specifically on fountain and water display design. Incorrect dimensioning for and of the components, conduits, cables etc often have serious consequences which cannot always be corrected later. Thus, for example, selecting the correct pumps and pipework has a direct influence on the subsequent energy costs. Sensible dimensioning of the fountain basins and water reservoirs has a considerable influence on the regularity and recurring costs of water changing. If this chapter can contribute to the thinking process" and help to eliminate design errors, then we will have achieved our objective.

Simple Fountain Design

Above: Most simple type of fountain unit by means of a submersible motor-driven pump.
Advantages: Little expenditure. Low costs
Disadvantages:

  • Relatively large basin depth.
  • Hazard for small children.
  • High water changing costs.
  • High cleaning expenditure since nodrainage.
  • Engineering fully visible Ungraceful appearance.
  • Risk of accidents since cable and pump directly accessible.

Option: Overflow/drain fitting, freshwater supply fitting, cable inlet fitting, underwater lighting, electrical controls, water level control equipment


Fountain Design with submersible pump

Above: Better appointed type of fountaln unIt by means of a submersible motor-driven pump
Advantages:

  • Low water depth at the perimeter.
  • Low water volume.
  • System under grate cover.
  • No risk of accidents.
  • More graceful appearance.
  • Well-appointed dueto built-in fittings for drainage, overflow and cable entry.

Disadvantage: High expenditure for basin, fittings and leads

Option: Freshwater supply fitting, underwater lighting, electrical controls, electronic waterlevel control equipment.


Fountain Design with dry pump

Above: Most simple type of fountain unit with dry-mounted centrifugal pump
Advantages:

  • Relatively little expenditure.
  • Relatively low costs, since appointed fittings not used.
  • No pump dismantling for winter.

Disadvantages:

  • Relatively large water depth Hazard for small children.
  • High water changing costs.
  • High cleaning expenditure since no drainage.
  • System partly visible.
  • Ungraceful appearance.

Option:
Overflow/drain fitting, fresh water supply fitting, underwater lighting, electrical junction box, electrical controls, electronic water-level control equipment.


Design with dry pump and acessories

Above: Better appointed fountain pump with dry-mounted centrifugal pump.
Advantages:

  • Low water depth at perimeter.
  • Low water volume.
  • System under grate control.
  • No risk of accidents.
  • More graceful appearance.
  • Well-appointed due to built-in fittings for overflow and drainage.
  • Pump protected in pump chamber.

Disadvantages:
Higher expenditure for basin, pump chamber, fittings and leads.

Option:
Fresh water supply fitting, underwater lighting, electrical junction boxes, electrical controls, electronic water level control equipment.


Fountain Design with pump vault

Above: Fountain unit with underground water reservoir as open system. Indispensable for units without a basin water surface.
Advantages:

  • System arranged largely covered.
  • Large dirt absorption capacity due to the large collecting screen.
  • Little algae formation, since water temperature is lower.

Disadvantages:
Higher expenditure for basin, water reservoir, fittings and leads.
Slightly higher energy costs do to increased pump size.

Option:
Fresh water supply fitting, underwater lighting, electrical junction boxes, electrical controls, electronic water level control equipment.


Dry pump with water reservoir desing

Above: Fountain unit with free standing water reservoir as a completely ready or pre fabricated unit with dry pump and all fittings.
Advantages:

  • Little site expenditure since it's a pre fabricated unit .
  • Easily maintained.
  • Large debris screen.

Disadvantages:
Higher expenditure for basin, water reservoir, fittings and leads.
Slightly higher energy costs do to increased pump size.

Option:
Fresh water supply fitting, underwater lighting, electrical junction boxes, electrical controls, electronic water level control equipment.
