Clean Water Bugs!

Residents of Mhamid in south eastern Morocco get their day to day water from bore holes, and many have water towers of one sort or another. Drinking water is sometimes from bottles, or a tanker delivery, or sometimes from the bore holes.Campsite owners asured us that the borehole water is fine to drink, but we decided to run things through a 50micron pre-filter before things even got as far as the camper tank and the subsequent filtration systems, or even using the water for clothes washing - good thing we did!What looks like sediment is actually bugs - look closely and you'll see the 'sediment' has a mind of its own. Then theres the bigger bugs, which you dont need to look closely for at all...This is the water we were told was fine for showering/washing up/clothes washing etc. Hmmm....
