NEW FACILITIES IN THE CITY
In this city, a number of innovative facilities were introduced for its infrastructure.
| UTILITY
TUNNELS
 In
the City Center Zone, utility tunnels (7.4km in total length) were constructed
to house conveyer pipes for the refuse collection, heating and cooling pipes,
power cables, telephone lines, water pipes and CATV cables. Tunnels make facility
installation and maintenance easier and eliminate a need for frequent road diggings
for the utilities, keeping the street clear for a smooth traffic flow.
| ZONAL
HEATING AND COOLING SYSTEM
A system to heat and air condition buildings in the
City Center Zone is installed to keep the city clean, to prevent fires, and to
save energy. Tsukuba Energy Service Ltd. started the service in 1983. It currently
supplies 36ha area in the City Center Zone with chilled water (for a part of the
area) and steam.
| REFUSE
CONVEYING PIPE LINE SYSTEM (Vacuum refuse collection system)
This system is installed for the city to be prepared
for a potential future deterioration of refuse collection efficiency due to the
increase in volume and worsening traffic conditions, and to modernize the method
as well as to save the labor for the cleaning program. Refuse deposited into a
chute is sent by an air flow through the conveyer pipe to the central depository.
In the 72ha area in the City Center Zone, a total of 11km long pipes are installed,
and has been in operation since 1983.
| CATV
CATV service was introduced to cope with difficulties
in the radio signal reception accompanying construction in the Science City, and
to assure clear TV image reception. ACCS Corp. has been re-broadcasting TV and
FM programs since 1983. Further, an experiment is under way since March 1985 to
utilize the available 30 channels of band-width for other advanced utilization
such as LAN. |
