After markings have been made, excavators are required to maintain
a minimum horizontal (side to side) clearance of two feet (24") between an
unexposed facility and the cutting edge or point of any power operated
excavating or earth moving equipment. For example, if the markings
indicate a 6" pipe is buried, the hand dig zone is 54" wide (6"+24" on
each side of the mark). If excavation is required within the hand dig
zone, the excavation must be performed very carefully, with vacuum
excavation or hand tools, and without damage to the facility or
undermining of lateral support.
MMU cannot locate water or electric services until proper Gopher
State One-Call procedures have been followed.
MMU will make every effort to locate facilities as promptly as
possible. Electrical Contractors

All NEW or remodeled and/or rewired Residential units must be
individually metered, with the exception of multi-unit facilities
providing care to elderly or disabled persons. Such multi-unit facilities
may be master metered in accordance with the state statute (326B.106.subd.12). In

more than one separate kitchen and bath facility.
Buildings used for Commercial business may be individually metered
for each business or may be master metered, BUT MAY NOT BE A COMBINATION
OF THESE TYPES OF METERING. If individually metered, the rate class of
each business in the building will be determined by their individual
electric consumption. For master metered buildings with demands less than
75 KW, the Commercial Rate will apply and the fixed charge will be
multiplied by the number of the businesses served and added to the energy
charge to obtain the total billing. For master metered buildings with
demands of 75 KW or greater, the Demand Metered Rate will

but may vary no more than 1 foot higher or lower. Proper meter height

When working as a contractor for MMU, the contractor must abide by all
OSHA and NFPA 70E Regulations including the use of personal protective
equipment (PPE). This includes the wearing of Category II FR clothing while
working near energized secondary services. All secondary voltages 240 volts
or less are considered Category II, 480 volts and higher are Category IV.
WATER METER INSTALLATIONS:
Water meters must be installed so as to leave reasonable
room for maintenance and repair. Reasonable room is a minimum 3' X 3' in
front of the meter. Do not install water meters behind other equipment
such as water heaters or softeners and do not install them flush against

Please notify MMU by 12:00 noon for a water inspection
that same day. TRENCH SAFETY:
Under OSHA regulations, a contractor is required to
provide a protection system for those individuals required to enter
excavations to protect them from cave-ins, material that could fall or
roll from the excavation face or into the excavation, or from the collapse
of an adjacent structure. This applies to all excavations that are 4 feet
in depth or more.
The proper protection can be accomplished by either sloping the
walls of the excavation at an incline away from the excavation so as to
prevent cave-ins, or by providing sheeting or shoring, or by use of a
manufactured trench box or trench shield.
OSHA regulations also require there must be appropriate means of
egress from the excavation, such as a stairway, ladder, ramp or other safe
means to make egress easily accessible.
MMU employees cannot enter your excavation to perform service line
taps, make inspections, etc., if the excavation is not properly protected
and egress provided. THAWING WATER SERVICES:
The property owner is responsible for the maintenance and protection of
their water system, including protection from freeze-up.
In the event of a freeze-up, MMU recommends the use of a hot water method
frozen water pipes. Hot water thawing creates no electrical or fire
hazard and is the safest method of thawing service lines.
Plumbers and property owners may request the use of MMU's thawing
equipment fro MMU customers. A water operator will accompany the thawing
equipment without cost to the customer. When thawing service lines, if MMU
personnel determine the service line was frozen in the public right of way, any
labor costs associated with thawing the line will be paid by MMU. NOTE: The
thawing machine will not work through a 90 degree valve. WATER CONNECTION PERMITS:
Water Connection Permits are issued at the Marshall Municipal Utilities
