摘要:

A few years ago, the city of Tallahassee, Florida, had to construct three new water storage tanks with overflow elevations higher than those of several older tanks to meet an increased demand for water. The city conducted several studies and determined that the best way to add needed storage in developed areas of the city was to raise the old tanks to the same elevation as the new ones. The project involved raising a 750,000‐gal (2.8 million‐L0 tank 39 ft (12 m) and a 500,000‐gal (1.9 million‐L) tank 46 ft (14 m). This paper describes the safety and technical requirements of this project.

摘要:

This month's column begins by stating that some of the questions submitted are a bit out of our line; often they are complaints about products that AWWA does not market. However, these questions are given the same consideration as the rest, going a step further by forwarding them to the appropriate persons for further research. In the meantime, while waiting for a reply, the enquirees can place questions on the Internet via one of AWWA's discussion forums of which there are four: AWWA's Regulatory Discussion Forum; the Technical Discussion Forum; the Section Discussion Forum; and, the WaterWiser Conservation Clearinghouse Forum. All can be accessed from AWWA's home page atwww.awwa.org.

摘要:

One of the most intense situations that can develop in a water treatment facility is a chlorine leak. While most leaks are minor, it only takes a small amount of chlorine to create an emergency situation. A release of 30 ppm of chlorine is considered immediately dangerous to life and health. A well‐developed emergency plan is the best protection for employees, the public, and the environment. This paper makes suggestions for improving emergency plans and responding to chlorine leaks.

摘要:

A critical component of a utility's success is the performance of its maintenance program. The rising costs of equipment, supplies, materials, and spare parts, in addition to the high‐tech nature of modern water treatment and distribution equipment and processes, make a well organized and effective maintenance program a necessity. By following the three simple steps of effective maintenance presented in this paper, any utility, regardless of size, can reduce costs and downtime, maximize equipment reliability, and provide the highest level of customer service.

摘要:

In order to protect pumps from exposure to weather and provide operator convenience for pump and valve maintenance, a “building on rollers” was designed. One wall of the building is stationary and two walls have rollers which sit on angle iron much like railroad tracks. The light‐weight structure can be moved by one person with little effort and provides excellent work space utilization.

摘要:

Upstream areas of watersheds contribute to downstream problems simply because of the cumulative effects of storm water runoff. In many cases, land development in upstream areas has occurred with little thought of the consequences to downstream communities. Many local government entities are autonomous units primarily concerned with land used within their own boundaries. A watershed management entity can assist with the management of land within a watershed. This paper describes activities that can be implemented in upstream areas to manage storm water runoff and discusses the implementation of watershed management plans. Also included are steps for pulling watershed communities together.
