Matt, Scott Cottrill here. Yes, I'd say when you look at the 2 businesses, right now, break it down between ADS and Infiltrator. We've talked about Infiltrator kind of in that reinvestment cycle, if you will, that they go through every 3 to 5 years. I'll start with demand. The demand that we're seeing across both businesses is significant. So as you look through the acceleration in investments, it's the same front of that, right? It's not that we're out of capacity or that we can't handle the growth. It's to make sure we can handle it efficiently and serve our customers as best we can and get our inventory health where it needs to be. So a lot of what you see on the Infiltrator side is to support growth. By and large, that's the bulk of what we're spending on that side.
On the ADS side of the house, again, it's still a big piece of the increase that we're seeing year-over-year is to support that demand that's coming our way. Now we're doing it, but lead times are moving out on us, and we need to kind of continue to stay in front of it and better serve our customers. So it's capacity and to support that demand and that growth that's coming our way. But I'd say also on our side, and we've talked about it. We've got a lot of productivity initiatives that are in flight, right? Our excellence initiatives a lot of those are still early innings. And we got to invest in tooling and molds and so forth to get those assets where they need to be more efficient as we move product around the network or to start reducing the amount of moving around the network that our product does before it gets to the customer. So you've got that.
And then automation, we've talked about it, but that downstream automation, if you will, is key within our businesses. And again, you know our network, we have 48 plants in the U.S. A lot of opportunity to get more efficient, make it a safer place for our employees. So a lot of things that we're doing there. Again, we spent close to $80 million this past year, a big increase year-over-year. So we're getting in front of it. And then the $150 million is not insignificant, but it is the best use and top priority of our capital deployment options, and we know that. So a big effort there. And we're also investing in internal resources to make sure that we can deploy and accelerate that CapEx organically.
