Iron Content in Ground Water
(OP)
Any suggestions on preventing iron (oxide?) buildup in french drain systems around foundation systems?

RE: Iron Content in Ground Water
It is probably a good idea to oversize the french drain to lengthen the time between cleanouts.
RE: Iron Content in Ground Water
I agree with bimr on this one.
We monitor the Bath Hot Springs system in the UK and the level of iron precipitation is horrendous, particularly for all the monitoring equipment!
The only way this is dealt with is by the ongoing program of cleaning and maintenance. Regular monitoring of your drains for the first few months (year?) would give you an indication of precipitation build-up times, which you can then apply to a maintenance program.
If only it were different!

RE: Iron Content in Ground Water
Just a thought.
RE: Iron Content in Ground Water
Unfortunately, since the material precipitates out of the water upon contact with air; there is no way to make a sacrificial anode. The only way to deal with the problem is by cleaning, either chemical or mechanical.
RE: Iron Content in Ground Water
bmir is on track....I have fought this battle and found that chemicals can work but also try to eliminate any points in the system where air can enter in. I had a real problem with a couple of monitoring wells and by simply installing new concrete pads around the wells and adding new caps it seemed to help.
good luck
