5 classes of quality between the clean water Piping From

Supervision for the quality be bacteriologically clean water use indicators that are tailored to the needs of the field on the basis of the number of coliform found in water samples are examined. There are 5 classes of quality clean water but between clean water from piping piping with non means there are differences in the requirements for each class as follows:

1. Class A contains total coliform less than 10.
2. Class B contains total coliform less than 11-50.
3. Class C contains total coliform less than 51-100.
4. Class D contains total coliform less than 101-1000.
5. Class E contains total coliform greater than or equal to 1000.

To clean water originating from non piping is classified as follows:

1. Class A contains total coliform less than 0-50.
2. Class B contains total coliform less than 51-100.
3. Class C contains total coliform less than 101-1000.
4. Class D contains total coliform less than 1001-2400.
5. Class E contains total coliform more than 2400.

In this classification are considered memenuhu terms is a quality grade.

Based On PP. RI No. 82 Year 2001 about water quality management and control of water pollution, water quality classification defined into four classes as follows:

1. First-rate water formation can be used for drinking water, and the other requires the establishment or the quality of water with the same uses.
2. Class two, water formation can be used for infrastructure/water recreations, freshwater fish cultivation, animal husbandry, water to irrigate pertanaman, and or other provisions that require the same water quality with the usability.
3. Third grade, water formation can be used for the cultivation of freshwater fish, livestock, water to irrigate pertanaman, and or other provisions that require the same water quality with the usability.
4. Fourth grade, the water allocation can be used to irrigate pertanaman and other provisions of the requirement or the quality of water with the same uses.

To determine the water quality there are several parameters among other things Do, BOD, and total dissolved solids.
