I ran two ‘low magic’ 3e campaigns, and both worked out quite well. However, both ended well before 10th level (I cut experience awards in half). Also, one had no ‘pure’ arcane spellcasters (only a bard and a cleric), while the other only had a sorcerer (and a multiclass rogue-cleric NPC for support).
Common sense and an ability to modify encounters on the fly should suffice.
However, on reflection, to keep ‘balance’ between spellcasters and nonspellcasters, I would suggest one of the following:
1. Require ‘pure’ spellcasters (wizards, sorcerers, clerics, druids) to multiclass every other level with a nonspellcasting class. Personally, I would
require that other class to be the ‘expert’ generic class from
Unearthed Arcana (that way the players could fine-tune the class through their choice of skills and feats).
2. Rule that all spells have, as a minimum casting time, a full round (spells that already have full round casting times or longer stay the same), eliminate all spells over level 6 (perhaps treat some of them as ‘incantations’ as per UA), and add 5 levels to the level requirements for all item creation feats (except scrolls and potions).
Those suggestions aside, running campaigns in the 1-10 level range is best (and indeed, may be sufficient).

There really is a simple answer to this.
As was mentioned, don't use fantastical creatures.
...
Figure the party is equal to about -2 for their level
…
Oh, and use a 45-50 point buy character. That right there is worth several levels worth of magic treasure.
And … give max hit points per level...
Those are all sound suggestions.

Here's what I do for a House Rule. Everyone is limited to 3 magic items. (Any more and they cease working or becoming cursed.) Total values and CRs otherwise stay the same.
This makes every magic item a special, signature item. Compare to fantasy literature or myth. PC's aren't draped in magic items, and they don't have a solution to every problem Inspector Gadget-style. All the players and DM can remember what those key signature items are.
That’s an interesting idea. How has it worked out in practice?
