    This is from American Gas Association

    Drip Box
    A box around a drip, accessible at grade level, which protects the drip and pipe.

    Thanks Scott. Never saw one before. I did lift the cover but only dirt inside.
    Must not be used anymore.

    It's still used if there is gas, it's just been filled in with dirt from over the years.

    However, when you find a drip out there, you need a drip in the house wherever the pipe runs or droops lower than other parts of the pipe. That drip outside is stating that the gas is 'wet' enough to require a condensation drip, which means they should be inside too.

    Provided the gas is still being used.

    Exclamation Re: Gas Drip.

    This drip was installed back in the days of wet gas when the city piped gas in usually from coal gasification plants. There are over a dozen types of manufactured gases including: producer gas, blue gas, carbureted water gas, town gas, etc. Gas was referred to by the town it was produced in since they all had different make up and therefore properties. While most natural gas comes from wells, about 25% comes from LP gas scrubbing. You can get liquified natural gas from the mid east refineries, which is poorly refined and of high caloric value just as you can make methane from coal gasification. Lots of types of gas. Since most of these are laden with various heavier hydrocarbons, it was found necessary to provide drips to protect the equipment. Most gas today has been well scrubbed so there is very little condensate but we still see a lot of other crap so sediment traps at the appliance will probably never go out of style.

    FYI, most mfd gas contains a lot of carbon monoxide.
