A modern approach to the maintenance of gravity sewers of public utilities

Summary

Most public utilities are facing typical problems associated with severe wear of wastewater collection, transportation and treatment systems, as well as with hydrogen sulfide emissions, and deterioration of the treatment facilities operation. One of the main reasons is untimely cleaning of pipelines transporting wastewater resulting in the secondary pollution of wastewater. The solution to the afore-referenced problems lies in the proper organization of the integrated maintenance of gravity sewers. The most rational combined approach to the maintenance of gravity sewers is proposed, that combines reducing the capacity of the own structures of water supply and wastewater enterprises with inviting outsourcing companies for the scheduled maintenance.
