Try to contact Eskom (South Africa) for some papers (www.eskom.co.za)
SCSASABB6, Distribution Standard, Part 4, Section 6
I also have a book by C.H.L. Sander, "An earthing design guide for single-wire earth return (SWER) systems in the Northen Cape region" This book was a tesis for his degree at the Technikon Free State, South Africa.
Some of his references:

Australia, May 1959 High Voltage Earth Return Distribution for Rural Areas, Fourth Edition. The Electricity Authority of New South Wales. Australia, June 1978 High Voltage Earth Return Distribution for Rural Areas, Third Edition. The Electricity Authority of New South Wales. Australia, June 1968 There is 40 references. Australia, New Zealand and South-Africa seems to be the countries with the most info regarding SWER-systems. Contact the local suppliers of electricity in these countries.
Rural electrification and SWER is covered in www.ruralpower.org including a description on using SWER, the links section includes downloads and further references. There also may be a South African standard (SABs) standard on SWER and there are also other South African guidelines around, which I would like to get a copy of. I have not had much luck with ESKOM in the past.
There is an Australian Standard (AS) on SWER isolating and distribution transformers which may also cover earthing. This standard can be purchased electronically directly from the AS website as a pdf.
SWER was originally patented by Lloyd Mandeno of New Zealand and for a while he also held the Australian patent (now lapsed). The above site has a pdf of Mandeno's original paper on SWER, which is great historical reading.
If you have a direct question on using SWER please feel free to contact me.
