The init.js file is huge and I suspect they don't cache it server side. I wrote an alternative version which loads faster, but the interesting data (water usage) is obviously available only from the City of Cape Town's server and it delivers the map in one giant png file. At least the aerial map is now cached tiles from another server. http://www.vwd.co.za/vwd/water http://www.vwd.co.za/vwd/water
