We were walking along Rolleston Street in Swindon one day and noticed a few drains close together, all with different designs on their covers.  Having never noticed them before, we thought they might be worth recording.  In a relatively short time we found many designs and manufacturers, and also realised some are actually service covers rather than drain covers.

No doubt all these designs have their own names (or at least an identifying code) and people more knowledgeable than us will recognise the manufacturers too.

We shall continue to photograph them and record their location too (which we didn't do to start with).  It is amazing what we miss as we wander around - usually we advise people to 'always look up' to see detail on buildings, but perhaps we should add 'and don't forget to look down occasionally too'.
