摘要:

After nine years of teaching physical education in middle school, I swore I'd rather dig a ditch than teach again. So here I am wearing blue jeans, driving a county truck, getting dirty and wet–and yes–digging a few ditches, but loving my job in water distribution operations.

摘要:

This month's question asks how midge flies infiltrate a water system, whether they are harmful, and how to get rid of them. The answer states that the presence of midges actually indicates a healthy surfce water source with good biological activity and are found world‐wide. The article discusses their life cycle and the fact that methods for controlling them depends on their species type, either parthenogenic or nonparthenogenic.

摘要:

United Water New York is in a unique water supply situation in the southeastern part of New York State. The utility, which provides water service to about 250,000 people in Rockland County, employs a network of 68 wells and two surface water sources to supply an average demand of 28 million gallons per day. It also receives an average of 43 inches of precipitation each year to replenish its water resources. This hardly paints a gloomy picture of a company in dire need of strict water conservation measures. Conservation, though, has been the backbone of United Water's demand‐side management program. In an effort to forestall the need for an additional water supply in the future, which could have costly impacts for customers, United Water and its regulatory agencies, the New York State Public Service Commission and the New York State Department of Environmental Conservation, embarked on an aggressive water conservation initiative. The major components of the program are: conservation device distribution; evapotranspiration (ET)‐based lawn watering education; citizen and commercial advisory groups; conservation curriculum for K‐6 school children; audit and retrofit of company facilities; leak detection study; operations water audit; and monitoring program to gauge effectiveness.

摘要:

It's summer and everyone is outside enjoying the mild weather. In our community, Shadow Hills Estates, California, we know it's also time to be on guard against the danger posed by single fire hydrants, located along our community's suburban equestrian trails. These hydrants can be dangerous if fallen upon by horses and their riders. We developed a protective safety cap for this type of hydrant to prevent injuries to equestrians, but it can also be used to protect injuries to bicyclists, skaters, hikers, and other recreational trail users. A list of materials and construction information is included in this article.
