Regular maintenance is essential to the operation of wells. Each well field management program should be tailored to its particular system and contain the following basic steps: establish a physical framework for the collection; organization and evaluation of important information; initiate a data collection and surveillance program; develop an operational control plan and develop long‐range plans; and finally, know the capabilities of your system and plan accordingly.

摘要:

Discussed is a hydrant flow diffuser which is used to minimize damage and danger from the force of the water flushed from the hydrant. The Metropolitan Utilities District of Omaha, Nebraska has developed a thin‐walled steel tube which is brazed to a bored‐out hydrant cap for threading into the large nozzle. A series of interior vanes breaks up the force of the water by whirling it first in one direction and then in another. Using this device, it is possible for one man to flow a number of hydrants in the same area, saving manpower and improving efficiency.
