Description:
Maintenance as discussed in this handbook includes the periodic improvement of drainage ways and certain accessory facilities, such as access roads. Small items of non-recurrent repair work are also included. All drainage needs some maintenance, but the need for maintenance work is greatest on temporary drainage construction. Most MCWA drainage has been of a temporary nature since the war emergency needs of 1942 and 1943 justified rapid construction with emphasis on conservation of materials and equipment. The cost of drainage maintenance can be held to a minimum if ditches are patrolled frequently, if obstructions are removed promptly, and if other needed work is noted. Immediate removal of an obstruction may take only a few minutes; but if it is allowed to remain, large quantities of silt may accumulate behind it. Bank slides and culvert blockage can be cared for with least expense if repairs are made at an early stage. Prompt attention to these maintenance needs also avoids unnecessary larvicidal costs.
