Drainage & Sewerage Systems & Contractors
Drainage and sewerage systems control drainage and sewerage systems to avoid health hazards and blockage of drainage pipes. Drainage systems include all types of drains, outlets and removal of excessive water and other products and byproducts. Drainage and sewerage contractors confer with supervisory personnel, owners, contractors, or design professionals to discuss and resolve matters, such as work procedures, complaints, or construction problems. Drainage and sewerage contractors develop and implement quality control programs besides planning and organizing direct activities concerned with the construction or maintenance of sewerage structures, facilities and systems.
