Has the municipal H2O noodle fallen out of vogue there Aegis? ~CS~
I have not heard that or have seen any bulletins on the subject. It might be municipal specific.
The issue may be cities moving to a PVC / ABS main system and there may not be enough copper left in the system to handle it. This is purely speculation so I can't say for sure.

Rules 10-700(1)(a), 10-700(4)
Manufactured grounding electrodes are those manufactured and certified to CSA C22.2 No. 41.
It is important that in-situ grounding electrodes provide an equivalent surface area contact with earth as do manufactured electrodes (see CSA C22.2 No. 41). Consideration should also be given to the effects that corrosion may have on the in-situ ground electrode impacting durability and life expectancy.
For example, an underground metal water piping system located at least 600 mm below finished grade and extending at least 3 m has traditionally been recognized as a suitable grounding electrode.
Similarly, the metallic reinforcement of a concrete slab, concrete piling, or concrete foundation and iron pilings in significant contact with earth at 600 mm or more below finished grade have also been found to be suitable in-situ electrodes.
Any metallic material encapsulated with a non-conductive compound to protect it from corrosion would not meet the criteria for use as an in-situ ground electrode.

New neighbourhoods in the Toronto suburbs are being built with non-metallic water mains so they have no choice about using something other than the water pipes. This guy probably thinks that happened because of code, which is wrong.

Yeah. The most common setup in those production line homes is a ground plate thrown in beside the foundation before backfilling. It's the quickest and cheapest solution. I have never seen anyone drive a rod for one of these places.

here's funny one ,,
Many many ,, yr's ago
about 20 yr's ago ,,
Cincinnati,,ohio,,
was setting modular house ,,
there local code want 2 ground rods ,, 8' apart
independent,, we also got roped into
home lightening ground want one every corner of home
Now then 5' down was solid stone, or granite over whole hill side ,,
so what end up doing was bending the ground rods 90 deg angle and laying
burying them 4' trench ,,
Inspector showed up looked at all them ,, ask if cut them off knowing the area ,,
I said know told what did he said y didn't I think that ,,
meets code ,, unlike cutting them off
So got the local code to indorse this method ,,in that granite area ,,
that's more like y some areas want ground plates ,,

I was doing my first transformer ground grid a couple months ago and was all worried that the last rod hit bedrock with 15cm left to go. My boss laughed and told me to get the operator to bend it over. The good ol' Canadian Shield is a bugger sometimes:laughing:
