Water Intake (general)

Intake plant for general Water Treatment Process
Intake Plant
The purpose of an intake system is to reliably deliver an adequate quantity of water for the best available quality. Reliable intake systems are costly and may represent as much as 20% or higher of the total water treatment plant investment. An intake system must possess a high degree of reliability and be able to supply the quantity of water demanded by a water utility under the most adverse conditions. for large capacity of water treatment plant, detail survey including hydraulic calculation, mapping, pumping Station, source of power supply and other scope have to be  done for designing intake plant. 

Each intake system presents unique challenges. Once the specific components are defined, the facility design must achieve the following :



  • Reliability during water level fluctuations or channel instability
  • Flexibility for water withdrawal at various depths, where desirable and feasible
  • Protection against hydraulic surges, ice, floods, floating debris, boats, and barges
  •  Location to provide the best available water quality
  • Prevention of entry of objects that might damage pumps and treatment facilities
  • Adequate space for routine equipment cleaning and maintenance
  • Facilities for removing pumps and other equipment for inspection and maintenance
  •  Location and design to minimize damage to aquatic life
  • Adequate space and facilities for receiving, storing, containing, and feeding treatment chemicals
