Thanks, Patrick. Please turn to Slide 4 and I'll cover our fourth quarter results. As Patrick indicated significant chip shortages impacting the utilities end market in the U.S. more than offset utilities growth in Europe and strong growth in the industrial segment globally. Given the quarter's challenges. The team did an outstanding job delivering on our commitments, increasingly tough circumstances with particularly strong performance on price and discipline on costs.
In a moment I'll give you a detailed performance by segment, but in short utilities was down 9%, a result of supply chain constraints acutely impacting our smart metering business in the U.S. Industrial grew 7% on sustained strength in China and healthy activity in the U.S.
Commercial was up modestly at 1% and residential was down 4% on challenging comparisons in the prior year when we grew mid-teens. Organic orders were up 23% in the quarter as demand for our technologies continues to be healthy across all segments. EBITDA margin was 16.2%, which was within our guided range. Year-over-year EBITDA margin contracted 260 basis points as productivity savings and strong price realization benefits were more than offset by inflation, mix, and strategic investments. We continue to invest for example, in geographic market coverage to serve increasing demand and enhance digital capabilities across the portfolio.
Our EPS in the quarter was $0.63 and please turn to slide 5 and I'll review the quarter's segment performance in a bit more detail. Water Infrastructure orders in the fourth quarter were up 30% organically versus last year. That includes a project cancellation last year in India. Which we discussed on our previous call. Otherwise, orders were up mid-single digits. This orders pace reflects resilient demand in our wastewater utility business in the U.S. and Europe as well as increasing demand for dewatering, particularly in emerging markets.
Water infrastructure revenue was up modestly in the quarter, healthy growth in industrial was partly offset by a small decline in our wastewater utility business in the U.S. where order to revenue conversion was challenged by ocean transit times. Geographically, results were mixed for the segment. The U.S. and Western Europe were up low-single digits and mid-single digits, respectively.
Healthy treatment deliveries in both geographies were offset by the delays, I just mentioned. Emerging market was down low-single digits, largely due to an especially strong performance in China last year EBITDA margin for the segment was down 50 basis points, a significant savings from productivity and cost reduction were offset by inflation in strategic investments. Please turn to page 6.
In the Applied Water segment orders were up 10% organically in the quarter driven by healthy demand in all geographies. Revenues increased 3% with high single-digit growth in industrial and a modest increase in commercial partially offset by sales down mid-single digits in residential. Geographically, the U.S. was up high single digits. Growth in all end markets was led by ongoing industrial recovery. Emerging markets was up mid single digits on continuing industrial strength in China and momentum in Eastern Europe. Western Europe delivered low single digits growth with moderate gains balanced across all end markets. Segment EBITDA margin declined 340 basis points in the quarter.
Material and freight inflation more than offset solid productivity gains and accelerating price realization and now let's turn to slide 7 and I'll cover our measurement and control solutions business. M&CS orders grew 28% organically in the quarter. Reflecting strong demand for our metrology solutions as well as healthy demand across all other applications in this segment including test and pipeline assessment services. This puts our M&CS backlog up 63% versus the prior year.
As we anticipated revenue declined 17% due to constraints chip supply. It's worth noting that the growing metrology backlog is both resilient and margin accretive, there have been no cancellations of AMI contracts and we expect large project deployments will resume in the back half of the year as component supply becomes available. Geographically, U.S. revenues were down 21%. Western Europe and emerging markets declined more modestly at 10% and 2% respectively, from pockets of growth in our water quality test business.
Segment EBITDA margin in the quarter was down 750 basis points. Volume was the biggest factor as this business get very strong operating leverage from higher revenues, which were constrained by the lower conversion of orders. Those volume effects along with higher inflation were partially offset by productivity gains and cost discipline. And now let's turn to Slide 8 for an overview of cash flows and the company's financial position.
Our financial position remains robust as we exit the year with $1.3 billion in cash and available liquidity of more than $2 billion. Net debt to EBITDA leverage is 1.2 times. After delivering free cash flow conversion of 181% last year. Our free cash flow conversion was 77% in 2021, slightly below our target for the year. While our team made continued progress driving collections we consciously increased our inventory safety stocks in the second half of the year to mitigate supply chain volatility. But we remain committed to at least [Technical Issues] conversion over the cycle.
A further item of note, as we previously advised, we are derisking our balance sheet with the buyout of our largest defined benefit -- pension plan in the UK. We expect to finalize this transfer in 2022, at which point we will recognize a non-cash charge of approximately $170 million, primarily consisting of unrecognized actuarial losses, which are reflected in equity today. Lastly in line with our capital allocation framework, today we announced an increase in our annual dividend of 7% and that is our 11th consecutive consecutive annual increase. Please learn -- turn to Slide 9 and I'll hand back to Patrick to look forward at 2022.
