Typically I have seen the water line up to and the water meter being owned by 
the water dept.   The backflow is the owners, but I don't believe the question 
was dealing with valves on the backflow so that's a moot point.  We always have 
them supervised.

Around here the water meter pits are installed on right-of-ways, not private 
property.  

So the moral of this story is it can vary from place to place.

Subject: RE: Are valves in pits sealed?

Craig:

Actually from a Fire protection main standpoint, most (Not all, in particular 
some PA areas) require the "Owner" to supply maintain and install the backflow 
prevention and metering DCDC or RPZDC. The "Owner" is responsible for the 
testing and is the maintainer of the backflow devices.
The backflow is installed to protect the municipal water system from the 
"Owners" water system and uses. In some cases the water dept. will specify the 
by-pass meter type and size and may also have specific requirements for the 
backflow prevention, but it is the "Owner that must supply and maintain these 
devices.

Water meter pits are usually installed on "Private" property (the property of 
the "Owner") not in public rights of way. Does the water dept or supplier have 
right of access, yes as does most any Gov. entity, or utility, supplying a 
service. They have the right to protect their equipment and distribution from 
any acts you may perform which endanger that system.

Since the water co's don't own maintain or install the equipment in the pit or 
the pit itself, they have very limited input on tampering of valves in the pit, 
if any.

As far as the control valves on the municipal main not being supervised, even 
NFPA 24 does not require all valves to be POST Indicator, or supervised, even 
for private fire service mains. They consider the fact that a special Key is 
needed to operate the valves, and that the valve box is not a item of common 
knowledge, or access, as sufficient.

Water meters and their associated valves are typically the property of the 
water department and considered as not being subject to the same NFPA 
requirements as sprinkler system valves.  

It's a fine line because if you had a municipal water source supplying a 
sprinkler system,  the control valves along the water main are not supervised, 
where does it change identity from a municipal water main to a fire main?
