Don't waste my hardwork and valuable time
Don't share as screenshot kind request

based on views next exams questions are yet to be updated
most viewed dept will get update at first So Dont screenshot and share

Don't share as screenshot -Stuff sector
don't waste my hardwork and valuable time

As Engineer i think you know how to respect another
Share it as link alone . don't share it as screenshot or any text material if u found this anywhere kindly report me . Don't #Admin :+6587090802

 *These questions are expected for the exams This may or may not be asked for exams .

    All the best....

          Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements 
If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates                                                      ~$tuff$£ctor
UNIT I WATER SUPPLY
Estimation of surface and subsurface water resources - Predicting demand for water- Impurities of
water and their significance - Physical, chemical and bacteriological analysis - Waterborne diseases
- Standards for potable water. Intake of water: Pumping and gravity schemes.
UNIT II WATER TREATMENT
Objectives - Unit operations and processes - Principles, functions, and design of water treatment
plant units, aerators of flash mixers, Coagulation and flocculation – Clarifloccuator - Plate and tube
settlers - Pulsator clarifier - sand filters - Disinfection - softening, removal of iron and manganese -
Defluoridation - Softening - Desalination process - Residue Management - Construction, Operation
and Maintenance aspects
UNIT III WATER STORAGE AND DISTRIBUTION
Storage and balancing reservoirs - types, location and capacity. Distribution system: layout,
hydraulics of pipe lines, pipe fittings, valves including check and pressure reducing valves, meters,
analysis of distribution systems, leak detection, maintenance of distribution systems, pumping
stations and their operations - House service connections.
UNIT IV PLANNING AND DESIGN OF SEWERAGE SYSTEM
Characteristics and composition of sewage - Population equivalent - Sanitary sewage flow estimation
- Sewer materials - Hydraulics of flow in sanitary sewers - Sewer design - Storm drainage-Storm
runoff estimation - Sewer appurtenances - Corrosion in sewers - Prevention and control – Sewage
pumping-drainage in buildings - Plumbing systems for drainage
UNIT V SEWAGE TREATMENT AND DISPOSAL
Objectives - Selection of Treatment Methods - Principles, Functions, - Activated Sludge Process and
Extended aeration systems - Trickling filters - Sequencing Batch Reactor(SBR) - UASB - Waste
Stabilization Ponds - Other treatment methods - Reclamation and Reuse of sewage - Recent
Advances in Sewage Treatment - Construction, Operation and Maintenance aspects. - Discharge
standards-sludge treatment -Disposal of sludge
