9-5. HEATING AND VENTILATION.
a. Heating. All pumping stations subject to possible freezing will be supplied with
automatically controlled heaters in the equipment areas. For unattended stations, temperatures
will be maintained at 40 degrees F. Attended stations will be heated to 65 degrees F. Although
wet wells are generally unheated, thermostatically controlled heaters may be used to prevent
condensation on walls and floors during cool weather, provided the ventilation system is shut off.
