For years little attention has been paid in waterline projects to what happens with water after it is flushed from the system. In the past, when constructing a waterline system up to 24-inch diameter, you would place calcium hypochlorite in the line during construction and then fill the line as slow as possible to keep the calcium in the proper place within the line, to chlorinate the system.

Understanding the requirements necessary to complete any water line project with a minimum number of issues is essential to completing any project successfully. That is one of the main reasons I write this newsletter, to share important knowledge about field chlorination and dechlorination.
This issue we would like to introduce a new product group from Measurement Technologies, Water Quality Sampling Stations. We are offering a HIGH SECURITY –SEVERE ENVIRONMENT style sampling station is based on an original design created by Seattle Public Utilities in 1975.
It’s hard to improve on the material construction of the housing of this station as specified in the original design.
Chlorination is one of the last
steps in any
pipeline project or repair. Planning for this phase at the beginning of any project is one of the
things you can do to assure this part of finishing any job comes off without
Project specifications should call out the approved process for chlorination that will be used at the end of the job.
