we try to stop, not only infiltration, but exfiltration, where sewage would actually leak out of the pipe. the head is larger, so it breaks away the old pipe and allows the new pipe to come in behind it. griffin: we are saving about 67% of the cost of actually digging old pipe up. clyne: it's less invasive than an open-cut process, where you would open the whole trench up and replace the pipe. it's called "trenchless" technology, so... that's as good as it gets. griffin: we don't have to dig up everyone's yard, and we refurbish that pipe at a much-reduced cost. another technique, the cured-in-place lining. it's equivalent to putting a large sock through the existing sewer. we form a new pipe inside the old pipe, and therefore we seal up all of the defects that allow rainwater to come in. hunter: we repair about 730 leaks a month in our system. griffin: the improvements that we've made will make the environment better. we had approximately 1,000 overflows occur in 1999. today, we've reduced overflows by 45% to 50%. and it's going to continue to improve as we go forward with the rehabi

today, it's as easy, if not easier, to insert or intrude into various systems and exfiltrate the information you need and with far less risk to the individuals. and then the third area, which has been alluded to here, is the growth of cyber and all of its iterations. and by that i mean a criminal robbing banks, the theft of intellectual property, exfiltration of information from dod or others. it is not lost upon us that several years ago, a group of individuals brought estonia to its knees as a result of a displeasure at actions that the estonian government had undertaken. and, more recently, in georgia, before the russians attacked georgia, it's no secret that they went a far ways to dismantling the command- andcontrol capabilities of the georgian authorities. and so in terms of terrorism, that would be a high priority, but also protecting our secrets from those governments and other individuals who want to steal them and then preparing -- particularly nsa and others -- the cyber -- i don't want to call it a battlefield -- but the cyber arena which has both offensive as well as defensive r
