ELECTRIC RAILWAY REVIEW 331 PIPING AND POWER STATION SYSTEMS—XXXII. BT W. L. MORRIS, M. E. As shown in Figure 257 (12-2), the bottom of the dis-charge waterway should be slightly lower at the point wherethe thawing-out pipe is run into the intake. The mouth ofthe discharge should be slightly higher than the intersec-tion marked low-point to insure water flowing throughthe line at times of low water. The discharge of the thaw-ing pipe should be a sufficient distance below the water toprotect it against freezing. The entire thawing line should. flOiY OF 5T/?£*rr ^ Figure 257-(l2-2). have not less than five feet of earth over it. In case the wateris taken from the cooling pond it would be unnecessary toprovide a thawing line to the mouth of the intake. The mouth of the discharge into the cooling pond shouldbe provided with an oil or grease catcher to prevent greasefrom getting into the pond. This is necessary not only toprevent the disfigurement of the banks and surface of thepond, but also to prevent the liability of oil reaching theboilers. A simple grease catcher is shown in Figure 258(12-3). This may be constructed of wood, concrete, brick, orother desirable material. The discharge from this compart-ment is through an opening located as far as possible belowthe surface of the water. The opening from the grease-catching compartment is provided with a valve and handlefor operating it. Inside of the grease-collecting compart-ment is an overflow into a trough which discharges into asewer or grease-catchin
