摘要:

Most treatment plant operators gather operating data in the usual way: make rounds, analyze samples, read pressure gauges and telemetry, and record the data on daily bench sheets. Some operators go on to summarize this information for plant and USEPA reports. And then, for most of us, it's promptly forgotten. A lot of time and effort was spent collecting these data. Why not use them to improve plant operations? With the right tools—like a personal computer and spreadsheet software—it is possible to use this information to spot important operating trends. The author demonstrates collecting and arranging data from the Lake County Bacon Road Water Treatment Plant and how it is used in analyzing operations.

摘要:

Developing a water conservation program is not a simple matter. There are many technical and policy issues that drive the process. These issues should be identified and evaluated jointly by policy makers and technical staff at the project's inception. This article highlights these key issues and concludes with examples of two Rhode Island water utilities that have recently implemented different types of water conservation rate structures.

摘要:

Trench compaction and yard repairs are usually time‐consuming, requiring several settling rains and landscaping trips to repair excavations to final grade. A handy alternative to a mechanical compactor is our gadget—the portable “sheep's foot.” A list of equipment and construction instructions are included in this article.
