The solution of using the treated effluent of wastewater treatment plants to feed groundwater in my country is under consideration. I would be grateful if you could share the experiences of other countries in this regard.
Here is some guidance for this matter in the UK Abbas
https://www.gov.uk/government/publications/groundwater-protection-technical-guidance/groundwater-protection-technical-guidance
You will need to measure the BOD5, COD, TSS, Metals, Salt, NOM and fecal coliform amongst other parameters of the waste water source and after the treatment of the waste water to make sure they are within the permissible limit before injection into the ground water.
You would also need to consider the technology/method used in the waste water treatment point/plant. The use of MBR is advised because this helps in the reduction of waste water treatment foot print.
You would also need to know the ground water recharge and discharge rate and volume so you know its capacity and how much can be infiltrated, and thus you would also need to know the precipitation, infiltration rate and runoff rate for that area too.

Thank you, Mark
I will use the useful information you sent

Dear john
Thank you for your kindness and prompt reply
In your experience, is there a successful case study in the UK
The requirement of Natural think like SISAL, SPONGE, CANAL, SCREENING, INLET, AND OUTLET, which highly reduces BOD and COD ( chemical oxygen demand)
Dear Researchers.
It is important to have the rate of infiltration at a specific region to be much lower than the feed of treated water for re charge into ground water zone.
This is done to ensure that the water for recharge has more time to have contact connectivity with soil..
Also to ensure adequate SAT ie Soil Aquifer Treatment which occurs.
Well wishes.
