Buried services are about five times as expensive as aerial services.

The 5-to-1 is installation only, but it's hard for decreased
maintenance and repair to make enough difference to tilt the balance.
In US's New England (where I live), there is enough rock that burying
is often impossible without blasting.

The original US example of burying all services is Columbia Maryland,
which was created from cornfields as a big development, so it was
practical to install the services using very large vibrating-blade
plows before anything else was built.
