Emblem of Amphoe Mueang Surat Thani

As far as I know, it is only the local governments and the provinces which officially have a seal with custom design fitting to the locality. The districts however use the emblem of the Ministry of Interior as their seal - except for the district in Bangkok, which also have custom seals. As I really love these sometimes very artfully designed emblems, it is a pity the websites of the local governments seem to be the only source to get any information on them - if I had the time and the connection I would research and compile much more of them...

Anyway, when I just recently checked the website of Mueang Surat Thani district - one of the few district offices which have their own website - I was surprised to see a emblem for the district.It shows the two main symbolic buildings of the district - the City Pillar Shrine (Sala Lak Mueang) in the city center and the Si Surat Stupa on the hill south of the city. Also the palm farms in the Tapi river estuary and the small boats used in the small channels of the estuary are depicted. I have no idea whether this is just an artful emblem designed for show, or also the official seal of the district - the Google search results for the Thai term ตราประจำอำเภอ don't indicate that any district actually uses a non-standard seal, the only images it returns seem to be very old seals from districts in Ubon Ratchathani province.
