7 Storm water drains Conservation of water resource is most important aspect of the project during construction and occupation phases. Storm water drainage planning, domestic water planning and sewerage transfer and sewage treatment planning are critical aspects of construction and occupation stages of housing projects. Storm water drains will be provided all over the site to meet the expected increase in the runoff during rainy seasons due to the impervious nature of the roads and other paved areas. It is proposed to maintain the levels as much as possible storm water is letting into side drains of main road. The expected runoff is calculated for the entire site is mentioned below. Calculation for Storm Water Drain Quantity of storm water (a) With out project Area of Catchment, A : Ha Run off Coefficient, C : 0.6 Maximum intensity of rainfall, I : 76 mm/hr Therefore Q : m 3 /sec (b) With project : Area for catchment for roof and road : Ha Area of Catchment, A : Ha Run off Coefficient, C : 0.9 Maximum intensity of rainfall, I : 40 mm/hr Therefore Q = : m 3 /sec Area for catchment for open areas : Ha Run off Coefficient, C : 0.6 Maximum intensity of rainfall, I : 76 mm/hr Therefore Q = : m 3 /sec Total Discharge : m 3 /sec But, Discharge, Q = A/V Where, A= Area of the Drain, V= Max. Permissible Velocity : 6 m/sec for concrete drain Area of drain, A = Q/V : m 2 Taking depth of drain as 0.6 m at the starting point : 0.6 Width of drain = Area/depth = : m 50 mm Width of the drain is to taken 50 mm and depth varies according to the slope of ground. 2-6

The water requirement during construction will be on an average of 30 cum/day with a peak demand of 60 cum/day, and during occupation stage in the order of KLD. The water resource available with the Municipal authorities was studied to identify the source and feasibility. The water resource both domestic water and sewage is dealt by the Greater Visakhapatnam Municipal Corporation (GVMC) in the GVMC area. Domestic Water: It is proposed to draw domestic water from the Municipal Supply (GVMC), which have been encouraging the bulk consumers. The water shortage if any during summer season will be drawn from ground water sources. The water requirement of the project during occupation stage is in the order of KLD. The water requirement during construction will be from ground water sources and the requirement is in the order of 30 cum/day. The water requirement for the project during the occupation stage is presented in table 2.4. The water saving for the housing project is presented in table 2.5.

9 The effective water consumption is reduced by 47.0 kl/day and the requirement will be in the order of 58.8 kl/day. The water balance of the project during occupation stage is tabulated in table 2.6. Table 2.6 Water Balance Input KL/Day Output KL/Day Domestic water from GVMC 58.8 HVAC Chillers 32.9 Recycled water 47.0 Recycled water 47.0 Water requirement for green belt during non monsoon 4.7 Losses approx 20% 21.2 Total Total The water used in the order of KL/day would generate 84.6 KL/day of wastewater, which has to be treated for reuse and or disposal. The effluent characteristics of wastewater are presented in table 2.9. Sewage Treatment based on MEMBRANE BIO REACTOR (MBR) technology (100 KLD): PROCESS DESCRIPTION: The Membrane Bio Reactor (MBR) process will consist of the following units 1. Screen chamber 2. Grit chamber 3. Equalization tank 4. Membrane Bio Reactor (MBR) 5. Final Treated Water Holding Tank 6. Sludge Filter Press Table 2.7 Characteristics of Waste water Parameter Quantity in mg/l p H Total Suspended Solids 300 BOD 250 Description of treatment scheme After above treatment, effluent is fed into INDION MBR tank. In MBR tank, MLSS (mixed liquor suspended solids) in the range of to mg/l are maintained. The high amount of bacteria gives better and complete removal of organic matter from the raw effluent in relatively small area. Oxygen required for the bacteria is supplied through the blower. The air is used both for scouring of membranes and supplying oxygen to bacteria. Oil and grease removal may also be necessary to prevent membranes from being coated. 2-8

10 The filtration is carried out by the suction pump directly sucking permeates water. The permeate water produced is clear and devoid of bacteria and viruses to the minimum levels. As the membranes are continuously under operation, they are polluted with organic or inorganic substances. Hence, chemical cleaning is carried out once in two to three months for removing substances polluting and clogging the membranes. Normal cleaners used are sodium hypochlorite and citric acid. Design of the unit Basic data Flow : 84.6 KLD Capacity : 100 m 3 Peak factor : 2 BOD : 250 mg/lit Total suspended solids : 300 mg/lit 1. Bar Screen Chamber Raw sewage from the source is usually received into the bar screen chamber from the EQT feed pump (clients scope). Screen provided will remove all floating and big size matter such as plastic bottles, polythene bags, glasses, stones etc which may otherwise choke the pipelines and pumps. In flow time : 16 Average flow : 5 m 3 /hr Peak factor : 2 Peak flow : 10 m 3 /hr Velocity through screen : 0.8 m/sec Clear area through rack opening : m 2 Clear width of opening at the rack : 0.03 (considering half pipe full flow) Number of bars : 2.19 Say 3 Nos. Hence Provide 3 bars Using rectangular steel bar in the screen, having 1 cm width, and placed at 5cm clear spacing. Gross Area of the screen required : m 2 Assuming screen bars placed at 60 0 horizontal sin 60 0 Gross Area of the screen needed : m 2 (59 cm 2 ) 2. Grit Chamber : The flow from the bar screen chamber is let into the Grit Chamber of minimum 2 hours capacity. This tank is provided to even out the flow variation, and to provide a continuous feed into the secondary biological treatment units. 2-9

11 Peak flow Q : m 3 /sec Providing a flow through velocity of 0.30 m/sec Cross sectional area of Channel (0.0033/0.3) : m 2 Surface area of channel (0.0033/0.013) : 0.3 m 2 Assuming depth d : 0.2 m Width of channel (0.011/0.2) : 0.06 m (say 0.2m) Length of channel (0.25/0.06) : 4. 5 m (say 4.2 m) Provide two channels each of 0.2 m wide and 4.5 m long with depth of waste water 0.2 m. 3. Equalization tank: Sewage generation is not uniform. The flow may be zero during non peak time. To optimize the size of plant, the plant is designed for continuous operation and hence there is a need to provide a buffer tank to store sewage during its peak hour generation and supply the same during lean or no flow hours. Hence our plant is provided with a good capacity of buffer tank called as EQUALISATION TANK. Screened and degreased sewage is then passed into the equalization tank to homogenize the sewage quality and also even out flow fluctuations and feed sewage of uniform quality at constant rate to subsequent treatment units. Air mixing is also provided to mix the contents of the equalization tank.a coarse bubble aeration grid or ejector system is provided to mix the contents of the equalization tank and also to avoid septic conditions in the tank. The flow from the bar screen chamber is let into the equalization tank of minimum 2hours capacity. This tank is provided to even out the flow variation, and to provide a continuous feed into the secondary biological treatment units. Average flow : 4.16 m 3 /hr Peak factor : 3.5 Peak flow : m 3 /hr Hydraulic retention tank = 2 hrs at Peak flow Hence required volume of the tank : m 3 Provide tank of : m 3 Capacity Assuming depth : 3 m Area : 9.72 m 2 Assuming length to width ratio (1:1) ; l=b length of the tank : 3.1 m say(4.6) width of the tank : 3.1 m say(4.6) Air required for agitation : 0.01 m 3 / m 2 min Total air required : m 3 /hr Air blower required : 40 m mwc Effluent transfer pump : 4.16 m 3 8 mwc 2-10

12 4. Membrane Bio Reactor (MBR): We have proposed with our state-of-the-art membrane separation technology called INDION MEMBRANE BIO-REACTOR (MBR), through this we will achieve desired treated volume and quality without addition of any chemicals and auxiliary equipments. MBR (Membrane Bio Reactor) is the latest technology in wastewater treatment. Indion MBR has many advantages such as consistent quality of treated water, reduction in space for installation and easier operation compared to conventional activated sludge process. The material of the membrane is PVDF (Poly vinylidene fluoride). PVDF is fluorine polymer, which has high stability for chemicals and good physical strength. The form of membrane is fiber reinforced flat sheet membrane. The membrane has small and uniform pore size. Therefore, the rejection property of this membrane is excellent. Almost all particles with sizes more than 0.1-micron meter can be removed effectively using this membrane. Average Flow : 5 m 3 /hr BOD : 250 mg/lit BOD after treatment : 2 mg/lit BOD removed : 248 mg/lit Total BOD load : 30 kg/day Assumptions F/M ratio : 0.1 Assumptions MLSS : mg/lit Volume of the tank : 20 m 3 Check for Detention time=(30/120)x 24 : 6 Hours (4-6) Assuming depth of the tank : 3.0 m ( F.B) width of the tank : 3.0 m Assuming Length of the tank : 2.5 m Air required : 70 m 3 /hr 2.0 kg of Oxygen is required for every Kg of BOD to be removed) % of Oxygen in air = 0.21 Density of air = 1.2 Blower efficiency (60 % air req.) : 120 m 3 /hr Provide 15% for equalization tank, 5 % for final tank and 5% for sludge holding tank : 30 m 3 /hr Blower capacity : 120 m m 3 /hr will draw from membrane filter unit Aeration tank with Membrane filter unit No. of membrane filter unit = 5/1.5 : 3.3 Say 4 units Modules : 200 m 3 Type : Spindle/Sheet Type Pore size : micron 2-11

13 5.Final Treated Water Holding Tank The treated effluent from MBR would be collected in the existing Storage tank. Chlorination would be done in this tank, and can be used for gardening without any further treatment. Cap: 100 m 3 /day 6. Sludge Filter Press: The sludge from the MBR tank has to be removed from the bottom of the tank by client and transferred to Filter Press either through pump. Before starting the desludging, shut off the aeration for 30 min and allow the sludge to concentrate at the bottom. After concentration, the bottom sludge valve can be opened to drain the required quantity of sludge. No. of plates : 24 Size of plates : 600 mm X 600 mm Plate moc (material of construction) : PP (poly propline) Type of operation : Hydraulic Power pack capacity : 2 HP The characterstic of the MBR process is the use of revolutionary submerged Ultra filtration membranes in the biological process water tank, so as to produce high quality permeate from domestic sewage, primary and secondary waste water, cooling tower blow down etc. The air bubbles are also used for biological reaction to decompose organic substances included in the raw sewage. PARAMETER Characteristics Of Treated Waste Water QUANTITY IN mg/l ph Total Suspended Solids < 1 BOD < 2 Disposal of Treated Wastewater: The treated water shall be treated and reused for flushing the toilets, followed by on land irrigation and HVAC make up water requirement, and on land irrigation. Hence all the recycled water is utilized completely and is considered as a zero discharge. 2-12
