Influent structure to water treatment plants .
Effluent standards of waste water.
Dear Nabeel
here you can find the recommended standard for wastewater treatment plant
I hope it will help you please see the attached link:-

In the case of wastewater treatment plants, it is important as it determines the dilution effect of the effluents. For water treatment plants, the stream flow is important viz-a-viz design capacity of the plant
Yes the receiving stream flow is important.
The receiving stream flow will generally determine the degree of treatment required based on the dilution available in the stream with smaller receiving streams requiring a higher degree of treatment for a given wastewater treatment plant discharge flow rate. The stream flow rate typically used in that calculation in the US is the 7Q10, which means the lowest flow in a stream for 7 consecutive days over a ten year period.
The discharge rate used in calculating the dilution varies somewhat but is often the maximum monthly average flow.
What's called A TMDL, or Total Maximum Daily Load is often calculated for a given wastewater plant based on a number of factors which includes the dilution ratio available that determines the mass loading allowable from a treatment facility.
In addition to the low flow issue you need to pay attention to channel stability when locating your effluent outfall and or diffuser
Yes, it is very important.
It influence the degree of treatment.
İf flow from stream low, care must be taken in the design of the treatment plant

Dear Nabeel Hameed Al-Saati

Your question - Is stream flow important in the design of water treatment plants and waste water treatment plants?
Specific to Influent structure to water treatment plants and Effluent standards of waste water.
The relevant data is required for both the plants in order to plan and design the components - that would make up the treatment system. Also for waste water and plain water treatment, it would be required to have an equalising chamber as the first component in the treatment plant, to take care of any intermittent increased/ decreased loading/ inflows etc.
The main data for the treatment plant is hydraulic retention time- HRT which is required to be afforded for achieving the desired treatment in the plant. The larger the HRT better is the treatment efficiency etc..Stream flow parameters would have details of the flow rate, the velocity of flow and the surface areas of filteration/ contact area- time in the process etc. to be taken into for the design of the plant .

Stream flow is really important for designing WWT plants, since you need to know flow variations according to seasons (if it is a really dry zone or a zone with high precipitation level) or if receiveing water from schools or facilities with certain schedules. Since you need to calculate physicallly your treatment stages or in case you need a tank for homegenize your inlet pH or flow (before beginnign your primary and secondary treatment).
Without flow rate you will be unable volume, surface area, velocity, etc of ponds,
Without flow rate you will be unable to calculate volume, surface area, velocity, etc of ponds,
