Television Inspection Equipment
		(1) The television inspection leadman will position the van approximately three (3) feet from the manhole being accessed. The camera can go in any direction, so the van will set up so as to have minimal effect on traffic.
		(2) The two foot long camera is driven through the sewer main via its two foot long tractor. At 4 feet, the camera and tractor weight about 75 pounds.
		(3) The smallest diameter the camera can go in is a 6-inch pipe. The tractor's wheels are adjustable and must be set all the way in for the 6-inch inspections.
		(4) In order to televise larger diameter pipes, the tires must be removed, and extensions, or larger tires, must be used.
		(5) In this case, larger tires will be used to televise a 12-inch diameter main.
		(6) The camera is now ready to be put into the sewer main.
		(7) The camera is lowered into the manhole and set into the channel in the direction the operator needs to go.
		(8) The inspection is done from inside the van where the operator watches the live video feed and also generates an inspection report using the District's software package, Win-Can. The television crew averages over 50,000 feet of sewer main televised each month. That's over 110 miles a year.
