Every water feature displays its optical and acoustical appeal against the background of its environment, be it an element of the garden, a park, or town landscape. The designer must take this into account. From the typology follows the technology. If you take note of the ten basic rules mentioned on this page, you will avoid the bad mistakes which are repeatedly encountered in practice, If there is creative fantasy in a confident interrelationship with the engineering, very attractive, enduring fountain units or water displays are a certainty. The ten most Important basic rules 1. Not under trees: Fallen leaves, insects and bird droppings contaminate the water and can clog up the suction filters in the pumping system. 2. Not exposed to high winds: Unfavorable wind conditions disturb the desired water pattern and can take the water in the fountains over the edge of the basin Height of water columns/jet should not be greater than the distance to the nearest edge of the basin. 3. Water-saving basin depth: To reduce water use during changes required for cleaning the basin and prevent accidents to children, the basin and thus the water depth, should be kept as shallow as possible (typically 16 to 18 inches). 4. Protection by cover gratings: The cavities in the fountain basin. which are necessary for accommodating the equipment should be covered by gratings. 5. Overflow/outlet to the drain: For easy emptying and cleaning of the fountain basin an overflow/outlet to the drainage should always be provided. 6. Freshwater supply: A permanently installed freshwater pipe with automatic topping up and pump drive running safety device should always be provided, especially for public installations. 7. Securing the power supply cables: Power supply cables should be installed in underwater junction boxes; this is essential for public installations. 8. Selecting the correct pump: Fountain pumps are subject to heavy endurance requirements and therefore, must be specially prepared for their intended application. 9. Selecting the correct electrical: The electrical must be matched to the pumps and lighting circuits and be provided with the special protective and safety equipment (GFCI) for fountain installations. 10. Choosing the right nozzles: There are a variety of nozzles available for architectural water fountain displays, keeping in mind the day and night visibility of a place before approving spray jets is a must.
