As of September 30, 2015, our backlog in Water Transmission was approximately $101 million, a 7% decrease from the $109 million as of June 30, 2015. Even though our backlog has decreased in dollars from the end of last quarter, the tons are almost exactly the same, reflecting the impact of falling steel prices and the harsh bidding environment. The backlog was about $138 million a year ago as of September 30, 2014, and yet the tons in backlog now are higher by 21%.
We expect the fourth quarter of 2015 will have higher revenue and backlog than the third quarter but it will still be challenging. The collapse in steel coil prices has reduced our revenue and the cutthroat bidding environment has severely impacted margins. We expect a large volume of bidding in the fourth quarter with about 35% to 40% of the year's volume of bidding.
The following is an outlook of the upcoming Water Transmission projects. The third segment of IPL, 15-2, started production in the third quarter and is expected to run through the end of 2015. The bid for the fourth segment of IPL, Segment 14, was recently delayed and is now scheduled to bid during the week of November 16.
Trinity River Main Stem, part of Lake Texoma project, has bid and we are expecting the project to award in the next couple of weeks.
Luce Bayou Interbasin Transfer Project in Houston, which was previously known as Houston MSA, is a major project that we expect to start bidding in mid-2016. This project is expected to represent an excess of 90,000 tons of steel pipe and will take place over a several-year period.
The Lower Bois d'Arc Reservoir is a pipeline being planned by the North Texas Municipal Water District, which represents approximately 30,000 tons of pipe requirements, which we expect to start in 2017.
We also expect additional opportunities to develop in Texas from the SWIFT program. We continue to monitor the market developments in California closely. The Fresno surface water program has started bidding and it will be several segments representing 20,000 tons of pipe bidding into 2017. The Cadiz water storage and transmission project, 25,000 tons of pipe is in progress of obtaining right-of-ways and the expectations are that pipeline construction will begin in 2016 and water delivery in 2017.
The Southern California reliner program is expected to spend $2.6 billion over the next 20 years relining existing prestressed concrete pipelines.
The Los Angeles pipeline replacement program will begin to replace large segments of the 550 miles of existing water lines. This program will extend through 2026.
The 127-mile Red River Valley water supply project has recently been revitalized. The goal is to have project design completed by 2018 and construction beginning in 2019.
The Southeast Oklahoma Raw Water Supply System, also known as Atoka, is 100-mile pipeline with bidding expected to start in late 2016 and early 2017.
We have planned $8 million to $9 million of total capital expenditures for 2015 matching our depreciation. We continue to be very cautious in our capital spending due to the current market conditions.
As of September 30, our tangible book value was approximately $231 million or about $24 per share. As of market close yesterday, we are trading at a 42% discount to tangible book value. Obviously, we believe very strongly in the long-term prospects of the Water Transmission business as we move to become a pure-play water company. Our quality, nationwide footprint, cost position and 45-plus percent market share uniquely position us to thrive as the market improves.
In Tubular Products, we implemented a production curtailment early in 2015 to address the challenging market conditions that have been created by extreme levels of imports and inventory. We have continued selling and shipping finished products and performing limited manufacturing as needed to fill customer orders. As we announced in July of this year, we are exploring the sale of our remaining energy tubular facility in Atchison, Kansas. This process has been slowed by the depressed oil price, unfavorable trade case ruling and decline in energy tubular demand. This process is ongoing and we have nothing further that we can discuss at this time.
As we have mentioned in the past, we are looking at a wide range of strategic opportunities for our Water Transmission business. It is the bedrock of our company and we have many of the experts of the industry within our company. A potential opportunity that we've also considered is a share buyback. While our new credit agreement allows us to contemplate share buybacks, our income level continues to be low. We intend to be cautious with a potential share buyback while market conditions remain depressed and prior to the sale of our Atchison facility. Even though we currently have no borrowings under our credit facility, as Water Transmission market recovers, we will need to build up our working capital to meet the market requirements, and we do not wish to limit the company's business opportunities by overextending the credit facility.
In closing, as we have previously mentioned, we expect our Water Transmission market to remain challenging for the near term as the municipal market is still working its way out of the trough. The bidding environment remains very competitive, with low market segment-wide backlogs and we are seeing nontraditional water market players testing the markets due to extreme conditions in other markets such as the energy market. All of these factors will continue to make 2015 a very challenging year.
But remember, 2011 through 2014 were 4 of the best earning years in a row that the company has seen in the Water Transmission business. 2015 is a normal cyclical down year. The fact remains that we are the dominant player in our segment of the water business, and we have over 45% market share with our sights set on achieving 50-plus percent of the market share. We have an extreme focus on costs and we have a long-term commitment to the water business that's demonstrated by our move to become a pure-play water company, and there continues to be a growing buildup of water infrastructure requirements. In fact, we're starting to hear water being referred to as a megatrend. And finally, due to the population growth and ongoing drought conditions, water resources will need to be moved from one place to another. That's our specialty, and that's what we do.
At this time, we'll be happy to take any of your questions.
