An inspector Dyson mystery, Burgess Hill

The mystery doesn't relate so much to what is written on the top layer of this sign, although the job title is in itself unsual enough, but to why this sign was written there and not a few inches higher, and to what could have been written originally...

Inspector To The
Burgess Hill Water
First I thought I would be left wondering what the last line could be but a closer look shows it was painted actually over the horizontal 'break' on the wall. Even before the lower part was covered by a coat of red paint it must have looked strange!
With regards to the original sign, all I've been able to decipher are a few letters here and there but no complete word has sprung to mind. That will remain a mystery...
