SIZE OF SEWAGE TREATMENT PLANT / CAPACITY  OF SEWAGE 

Before Calculating the size of STP calculate Total Domestic  Water Demand Required

Total domestic water demand  =  TWD 

Estimated Sewage X = 90 % of TWD

Estimate Sewerage X  = 90/100 * TWD

For  If TWD = 1600 KLD( Kilo  liter per day)

Capacity of S.T.P           = 90 / 100 * 1600 KLD

                                                      = 1440 KLD

 Space Requirement For 1440 Cum STP = 

Consider Total Depth 3.00 (Standard Depth )

Liquid Depth  L = 3.0 Mtr

 Size Of STP = 1440/3 = 480

                        =480/15 (Breadth Assumed) = 32 (Width )

Total Space =15*32*3= 1440 CUM
