I've tidied up the entries for Severn Trent Water, of which there were quite a number of unverifieds.
Of those which are left, most are Derby numbers. Helpfully, someone posted a comment alongside one of them which said that Severn Trent's main contact centre is based in Raynesway, Derby.
Severn Trent's own website has
a location map (PDF) for this office which gives the address as Severn Trent Water Ltd, Raynesway, Derby, DE21 7BE (or DE21 7JA for post). This division of Severn Trent is, or was, sometimes known as Integra Utility Services.
I have removed all these Derby (01332) numbers, some of which are unobtainable and all of which are unverified:
- *686023 - Call centre direct [0845 750 0500]
- 686051 - Water meter installation team [0845 709 0646]]
- *686126 [0845 750 0500]
- *686446 - Water meter applications [0845 709 0646]
- 886782 - Customer services Mon-Fri 9am-5pm [0845 750 0500]
- 886995 - Was provided by Severn Trent Trust Fund [0845 750 0500]
The numbers in square brackets are the 08 numbers each alternative was submitted for. Those market with a * are unobtainable.
There are also two other unverified entries which appear to be of relevance:
Integra Utility Services 0845 456 7063 01332 635030 Water Metering service subsidiary of South Staffordshire Water PLC and Severn Trent Water Services
South Staffs Water (Integra) 0845 456 7063 01332 635030 This is the number for water meter requests based in Derby (same number for Severn Trent Water)
There is an unconfirmed link between Severn Trent Water and South Staffs Water, particularly in respect to Integra. The number 0845 456 7063 is one used by South Staffs Water.
01332 280920 is apparently the metering services department, and may put calls through to customer services if asked nicely.
The clues above lead me to suggest that they have numbers in the range 686xxx (certainly 6860xx through to 6864xx), and possibly 886xxx. I also suggest that perhaps 01332 635030 is the main switchboard number for the Derby office.
