our crude oil logistics segment generated operating income of $ 122.9 million during the year ended march 31 , 2018 , which included a gain of $ 108.6 million on the sale of our previously held 50 % interest in glass mountain pipeline , llc ( “ glass mountain ” ) . water solutions our water solutions segment provides services for the treatment and disposal of wastewater generated from crude oil and natural gas production and for the disposal of solids such as tank bottoms , drilling fluids and drilling muds and performs truck and frac tank washouts . in addition , our water solutions segment sells the recovered hydrocarbons that result from performing these services and sells freshwater to producers for exploration and production activities . our water processing facilities are strategically located near areas of high crude oil and natural gas production . a significant factor affecting the profitability of our water solutions segment is the extent of exploration and production in the areas near our facilities , which is generally based upon producers ' expectations about the profitability of drilling and producing new wells . the primary customer of our wyoming facility has committed to deliver a specified minimum volume of water to our facility under a long-term contract . the primary customers of our colorado facilities have committed to deliver all wastewater produced at wells within the dj basin to our facilities . most customers of our other facilities are not under volume commitments , although many of our facilities have acreage dedications or are connected to producer facilities by pipeline . our water solutions segment generated operating income of $ 210.5 million during the year ended march 31 , 2019 , which included a gain of $ 141.3 million on the sales of our bakken water disposal business and our south pecos water disposal business ( see note 16 to our consolidated financial statements included in this annual report for a

propane , butane , and other products from refiners , processing plants , producers , and other parties , and sells the products to retailers , wholesalers , refiners , and petrochemical plants throughout the united states and in canada . our liquids segment owns 27 terminals throughout the united states and a salt dome storage facility joint venture in utah , operates a fleet of leased railcars , and leases underground storage capacity . we attempt to reduce our exposure to price fluctuations by using back-to-back physical contracts and pre-sale agreements that allow us to lock in a margin on a percentage of our winter volumes . we also enter into financially settled derivative contracts as economic hedges of our physical inventory , physical sales and physical purchase contracts . our wholesale liquids business is a “ cost-plus ” business that can be affected by both price fluctuations and volume variations . we establish our selling price based on a pass-through of our product supply , transportation , handling , storage , and capital costs plus an acceptable margin . weather conditions and gasoline blending can have a significant impact on the demand for propane and butane , and sales volumes and prices are typically higher during the colder months of the year . consequently , our revenues , operating profits , and operating cash flows are typically lower in the first and second quarters of our fiscal year . the following table summarizes the range of low and high propane spot prices per gallon at conway , kansas , and mt . belvieu , texas , two of our main pricing hubs , for the periods indicated and the prices at period end : replace_table_token_7_th 54 the following table summarizes the range of low and high butane spot prices per gallon at mt .

ethanol , and biodiesel marketing operations , purchase s refined petroleum and renewable products primarily in the gulf coast , southeast and midwest regions of the united states and schedule s them for delivery at various locations throughout the country . in addition , in certain storage locations , our refined products and renewables segment may also purchase unfinished gasoline blending components for subsequent blending into finished gasoline to supply our marketing business as well as third parties . we sell our products to commercial and industrial end users , independent retailers , distributors , marketers , government entities , and other wholesalers of refined petroleum products . we sell our products at terminals owned by third parties . story_separator_special_tag during the year ended march 31 , 2019 , we recorded a net loss of $ 107.4 million , which included a loss of $ 105.0 million on our transaction with a third party in which

replace_table_token_13_th wastewater disposal service fee revenues . the increase was due primarily to an increase in the volume of wastewater processed at existing facilities as well as facilities acquired from acquisitions . we continue to benefit from the increased oil and gas production and rig counts as compared to the prior year in the basins in which we operate , particularly in the permian basin . recovered hydrocarbon revenues . the increase was due primarily to an increase in the volume of wastewater processed at existing facilities as well as facilities acquired from acquisitions and an increase in crude oil prices ; however , these revenues were negatively impacted by a lower percentage of skim oil volumes recovered per wastewater barrel processed . this lower percentage was due primarily to an increase in wastewater transported through pipelines ( which contains less oil per barrel of wastewater ) , as well as operational changes in the dj basin . other service revenues . other service revenues primarily include solids disposal revenues , water pipeline revenues and freshwater revenues , all of which increased during the year ended march 31 , 2019 due to increased volumes as well as acquisitions . cost of sales-excluding impact of derivatives . the increase was due primarily to an increase in expenses to bring wastewater to certain of our water solutions facilities . 62 cost of sales-derivatives . we enter into derivatives in our water solutions segment to protect against the risk of a decline in the market price of the hydrocarbons we

higher volumes processed at existing facilities and facilities acquired from acquisitions , partially offset by cost reduction efforts . due to the higher volumes processed , our cost per barrel has decreased , as shown in the table above . also contributing to the increase was an increase in acquisition expenses related to one of our ranch acquisitions . depreciation and amortization expense . the increase was due primarily to acquisitions and developed facilities , partially offset by the disposition of our bakken and south pecos water disposal businesses and certain intangible assets
