Exhibit 99.1

MUELLER WATER PRODUCTS TO CLOSE

U.S. PIPE MANUFACTURING PLANT IN NORTH BIRMINGHAM

(ATLANTA) — Mueller Water Products, Inc. (NYSE: MWA) today announced that U.S. Pipe and Foundry Company LLC (U.S. Pipe) will close its ductile iron pipe manufacturing plant in North Birmingham, Alabama by March 31, 2010, eliminating approximately 260 positions.

Production from the North Birmingham plant will be managed using existing capacity at U.S. Pipe’s Bessemer, Alabama and Union City, California facilities.

Over the past three years, U.S. Pipe has focused on streamlining and upgrading its operations to improve safety and quality, and reduce costs. Most significantly, the Company invested in a new automated ductile iron pipe manufacturing process that increases quality and output while substantially reducing costs. A facility for this new manufacturing technology was built adjacent to its Bessemer, Alabama facility.

U.S. Pipe is the first ductile iron pipe manufacturer in the United States to employ these state-of-the-art machinery and transport systems which capitalize on continuous flow and computer-aided processes. The automated process has been in successful use since September 2008.

These steps have helped increase U.S. Pipe’s productivity. However, given the downturn in the overall economy and especially our end markets, we believe further action is needed to address excess capacity in our plants.

“The performance of our automated manufacturing process has exceeded our expectations for quality, efficiency and overall productivity. We believe it is the most efficient ductile iron pipe manufacturing process in the United States, and it produces exceptional quality pipe,” said Gregory E. Hyland, chairman, president and chief executive officer of Mueller Water Products. “As a result, we are able to consolidate production, eliminate fixed costs and improve productivity by leveraging the investment we made in upgrading our manufacturing technology which commenced operations 16 months ago. With the growing awareness of the need to repair or replace the country’s aging water infrastructure and a residential construction recovery, we believe that we will see increased demand for ductile iron pipe over the longer term. We have sufficient capacity to meet any foreseeable increases in demand and can readily accommodate future increased capacity by expanding use of our manufacturing technology.”

In connection with this action, the Company expects to record a restructuring charge of approximately $15 million, most of which will be taken in the second quarter of fiscal 2010, ending March 31, 2010. This charge is comprised of approximately $6 million of asset write-offs and $9 million of cash costs, including severance and other costs associated with the closing. Incremental cash operating expenses associated with the restructuring of approximately $2 million are expected to be incurred primarily during the second half of fiscal 2010. Savings on an annualized basis are projected to be in the range of $20 million to $25 million, with net savings of approximately $6 million to $8 million expected to be realized in fiscal 2010, including the estimated $2 million incremental cash operating expenses.
