Goal
Generate project-level information about construction water use.
CREDIT REQUIREMENTS
Requirements
Create a spreadsheet that records total water use during construction. This
spreadsheet should identify, at minimum:
- Dates of use.
- Amounts of use.
- Locations and sources of water used.
- Potability of water source(s).
- Each construction activity requiring water use.
- Total water quantity used in each construction activity.
- Method of measurement to determine total quantity used.
- Disposal practice for unused water.
- Type of water use permit, if any.
- Total cost of water used from each source, if any.

In the GGC countries (UAE, Qatar, Bahrain, etc), although studies have proven the great enhancement of soil properties when mixed with salt water (max. dry unit weight, optimum moisture content and CBR), road construction specifications prohibit the use of salt water in soil mixing and compaction and insist on the use of potable water and thousands of gallons of saline ground water are dumped into the sea through dewatering processes during major construction projects. The case may not be much different in the US (not sure).
The use of salt water in soil mixing and compaction should be encouraged in roads projects through voluntary credits.
