Feasibility study on injecting treated sewage water on groundwater
1- Major Aquifers including both (Primary & Secondary) based on available data including the quality data such water quality parameters ( ph, temperature, electric conductivity, nitrate, phosphate contamination levels, ammonia, oil,) and also the available quantities of those aquifer proven reserves. 2A-Detailed and comprehensive feasibility study including a literature on injection the treated wastewater on the groundwater aquifers in Saudi Arabia.
This point is linked with point no. 2B (the simulation). 2B-6- Simulation on the for example the blending between the fresh (treated) water and the brackish or aquifer water, the degradation rate of the contamination if treated water is injected, or for example if it contains some chemicals or heavy metals. how can that present risk to the nearby consumers.
3- Effects of man-made activities such as Agricultural activities on the groundwater quality based on data and link it to GIS where are the agricultural activities such as farms in Saudi Arabia . 4- TSE (Treated Sewage Effluent) available data quality and quantities from Jeddah municipality or eastern province dammam or Riyadh.

Firstly, it is important to evaluate the quality of the major aquifers in Saudi Arabia, including both primary and secondary aquifers, to determine their suitability for groundwater injection. This will involve analyzing various water quality parameters such as pH, temperature, electrical conductivity, nitrate, phosphate contamination levels, ammonia, oil, and other potential contaminants.
Once the aquifer quality data is gathered, a detailed and comprehensive feasibility study should be conducted to determine the feasibility of injecting treated wastewater on the groundwater aquifers in Saudi Arabia. This study should include a review of existing literature on similar projects, including successes, challenges, and potential risks.
To assess the potential blending between fresh (treated) water and brackish or aquifer water, a simulation should be performed to determine the degradation rate of contaminants if treated water is injected. This simulation should also assess the risk of contamination if the treated water contains chemicals or heavy metals, which could potentially impact nearby consumers.
In addition to assessing the suitability of the aquifers for wastewater injection, it is also important to evaluate the impact of man-made activities, such as agricultural activities, on groundwater quality. This Assessment should include a review of data on agricultural activities in Saudi Arabia, such as farms, and link this data to GIS for analysis.
Finally, to complete the feasibility study, data on treated sewage effluent (TSE) quality and quantities should be collected from Jeddah municipality, eastern province Dammam, or Riyadh. This data will be crucial in determining the feasibility of the project and the potential impact on groundwater quality.
