Standardized Costs for Water Supply Distribution Systems

摘要

Presented within the report are cost data for construction and operation/maintenance of domestic water distribution and transmission pipelines, domestic water pumping stations, and domestic water storage reservoirs. To allow comparison of new construction with rehabilitation of existing pipelines, cost data is included for cleaning, application of cement mortar lining, slip lining, and a proprietary process called Insituform. Construction cost data for water pumping stations include construction of new installations, including package plants, as well as expansion of existing pumping stations. Operation and maintenance requirements including labor, electrical, and materials are also presented. Storage reservoir construction cost data is presented for ground-level and elevated steel reservoirs, and below-ground and ground-level concrete reservoirs.
