You are ask to prepare a project Quality management Plan (PQMP) that deal with drinking water and microbial contamination. water quality is a significant issue the world over and providing clean drinking water is a feature healthcare in all countries depends on. The PQMP you design should deal with all aspects a public health unit or Goverment Environmental department would have to deals with drinking water issues, in particular microbiological contamination.

Therefore, what you should be considering in preparing this plan is all the quality issues a PH or Environment unit (department) would have when dealing with drinking water for the public. This could entails but not limited to:

Who collect samples?

How samples are collected

Where samples are tested, how often

How is a lab accredited, is it even accredited

What tests are used, why are they used

How is reporting done

Who contacts the public

When are boil water advisories issued, and by whom

When are boil order lifted

What criteria do people need to carry out this work, do they have to be accredited, have a certain degree etc.

In general, you should consider that you are working in goverment department, and you are tasked with the job of designing a quality system to ensure citizens have good potable drinking water. To do this you need to make sure a quality system is in place to ensure all the things that should be done are being done correctly and documented as such. To accomplish this, you will have to do background research on drinking water testing for microbial contamination. Specific issues such as writing policies, decisions on how testing is done, what quality standards are used, how quality assurance is determined and what quality control test are used should be included in your plan among other things.
