Since our WTP service area consists mainly of villages with populations less than 50,000 capita, we will use a water consumption of 135 l/c/d.
The rate of increase of consumption rates can be calculated as 1/10 of the rate of increase of the population.

Fresh Water Pumping Station
+Proposed Sanitary System
Comes from surface water (Rayah El Beheiry)
Water is allowed to flow through a screening process before entering the Raw Water Pumping Station
The first step in purifying surface water is to remove large debris such as sticks, leaves, trash and other large particles, which may interfere with subsequent purification steps
The water will be pumped to higher water head using Centrifugal Pumps
Intake Source
+Proposed Sanitary System Cont’d
Allocates the water to the Clariflocculator
As the water is distributed along the tanks, Primary Disinfectant (Pre-Chlorination) is added to the raw water
Water is chlorinated to minimize the growth of fouling organisms (e.g. Algae) on the pipe-work and tanks
Moreover, the Distribution Chamber receives Recycled Backwash Water (RBW)
Main Distribution Chamber
+Proposed Sanitary System Cont’d
Are Sedimentation Tanks, were the coagulation, flocculation, mixing and sedimentation process all take place
Coagulant is Added to the Raw Water
IT enables Small Particles to form big flocs faster
Flocs Precipitate at the bottom forming sludge
Sludge is collected in the Sludge Collecting Tanks
Clariflocculators contain circular channels that allow the overflowed water to move to the next treatment process (Rapid Sand Filters)
Clariflocculator
+Proposed Sanitary System Cont’d
Water moves vertically through sand that often has a layer of activated carbon or anthracite coal above the sand
The top layer removes organic compounds such as Algae
Most particles pass through surface layers but are trapped in pore spaces or adhere to sand particles
Filters must be backwashed using water, in order to prevent pores between sand from becoming blocked
Rapid Sand Filters
+Proposed Sanitary System Cont’d
Final disinfectant (Chlorine) must be added to get rid of all the harmful microorganisms that make it through the RSF
Treated Water enters into the Ground Reservoirs and are afterwards pumped using Treated Water Pumping Station
Water is pumped to Elevated Tanks and various Water Networks that the plant feeds
Some of the water stored in the Ground Tanks, is used in the backwash process
Ground Reservoirs/Tanks
+Proposed Sanitary System Cont’d
The treatment water process is cut off for a distinct period, to allow the backwash process to take place
Water is pumped backwards from the ground tanks to the filters, removing particles stuck in the RSF
Water is pumped backwards to the Main Distribution Chamber that allocates it back to the Clariflocculators
Some particles precipitate in the Backwash Water Settlers, which are the removed to the Sludge Collecting Tanks
Backwash Process
+Proposed Sanitary System Cont’d
Gravity thickeners are heavy-duty circular collectors that are custom designed to handle concentrated municipal and industrial sludge
Allows Sludge to concentrate (Thickening)
After the Sludge concentrates at the bottom, it is pumped to the Sludge Lagoons
Collected water is pumped back to the Main Distribution Chamber, which then distributes it to the Clariflocculators
Gravity Thickener Tanks
+Schematic design
+Tasks
Design the general layout of the water treatment plant
Study the water treatment process and the necessary components of a WTP
The structural design of the water tanks and the different buildings of the project
Design the required sanitary system needed to transport the water throughout the treatment cycle, beginning from the intake until the exit
