Feasibility Studies for Water and Waste Water Solution

Published on by in Technology

Hello All,

I am working on a proposal Methodology to conduct feasibility studies FOR WATER AND WASTE WATER MANAGEMENT STRATEGY FOR A 1,000-HECTARE. 

The permanent water and waste water solutions must be capable of producing 10,000 m3 to 15,000 m3 of potable water per day and handling about 7,000 m3 to 12,000 m3 of waste water per day. 

Please, anyone with useful information or with past experience should kindly help. I need to come up with the best Technical Proposal. Location is Lekki Island Lagos Nigeria. Thank you

    These posts are a waste of time, no hearing back from the original person who posted the question?

    We are all busy, at least a feedback from the originator is expected. We are here to help, however the topics need a closure, otherwise we will be here disclosing ideas for ever! 

  2. Hello wastewater in view of the pollution they contain can not provide drinking water. It's impossible. on the other hand, they can produce irrigation water from the surrounding biodiversity, which reduces the abstraction of underground resources. biological sanitation removes all feces and dissolves urine pollution. it removes any alternative solution of waste handling this liquid is productive

  3. Bonjour

    les eaux usées au vu de la pollution qu'elles contiennent ne peuvent pas donner d'eau potable. C'est impossible.

    par contre elles peuvent produire de l'eau d'arrosage de la biodiversité environnante ce qui permet de réduire les prélèvements des ressources souterraines.

    l'assainissement biologique élimine la totalité des matières fécales et dissout la pollution urinaire.

    il supprime toute solution alternative de manipulation des déchets, ce liquide est productif

  4. Feasibility ​studies potable water need ​ critical ​input & output ​analysis of ​Water for ​proposed ​geographical ​boundary.  ​This will ​include Raw Water analysis report , Details of inhabitation on the land , Quantity and quality of waste water generated, Intended use of treated waste water , Quality and quantity of treated waste water required, Its distribution and collection net work details , Details of rain in the area ( Anual averages) . Then topography of the area, gredient details. Apart from this required total ​precipitation, ​potential of ​rain water ​harvesting, ​Import and ​export of water ​from the ​geographical ​boundary. It ​also includes ​water going ​along with the ​product and ​evapo-​transpiration. ​Water Foot ​Print analysis ​will take you ​to perfection. ​I will suggest ​the centralized ​sewage ​treatment plant.​ Depending on ​the available ​area the ​process can be ​selected. ​Oxidation pond ​may be a good ​option if land ​is available.

  6. Hi Marcus,

    If you are referring to LFZDC's Lekki Free Trade Zone (SW Quadrant) then the area is 16,500 ha with 285 ha planed as waterbodies (canals) connected to the Lekki Lagoon. The planned waterbodies will divide the island into eight catchments.

    In lieu of any WQ standards by the Nigerian Authorities, the planned waterbodies were proposed to comply:

    a) The Water Framework Directive of the European Union (2000/60/EC) which provides guidelines on the minimum water quality standards required for the protection of aquatic ecology in all surface waters,

    b) The Bathing Water Directive of the European Union (2006/7/EC) which provides guidelines on the microbiological standards for recreational waters, and

    c) The World Health Organization (WHO) guidelines on the drinking water quality standards for the safety of human health.

    Only one STP is planned. The following effluent characteristics were given. 

     Expected sewage treatment plant pollutant concentration values

    Water quality parameter

    Average values used at the sewage treatment plant

    DO (mg/l)

    1

    BOD (mg/l)

    30

    TDS (mg/l)

    200

    Nitrates (mg/l)

    20

    Ammonia (mg/l)

    0.6

    Ortho-phosphates (mg/l)

    5

    Faecal coliforms (no/100ml)

    400

    Lead (mg/l)

    Copper (mg/l)

    Nickel (mg/l)

    Iron (mg/l)

    20

    Manganese (mg/l)

    Zinc (mg/l)

    So you will have to find solutions to treat the industrial and domestic wastewaters to meet the above criteria as a minimum.

    As regards to the water supply: Lekki Lagoon is a freshwater body and the water supply is expected to be sourced from this. So the treatment plant for water supply will be required to treat this water to potable standards. Saltwater intrusion was found not to be an issue.

    I am posting the above as this will help others to help you find appropriate solutions. All the best.

    1. The average ​values used at ​the sewage ​treatment plant ​you listed apart from Faecal coliforms (no/100ml) 400 and other metals concentration, is for potable/drinking water not for wastewater

  7. It is difficult to give you the best steer over this platform, but typically the content of a feasibility should consider the location, the environmental impacts, the project scope, technologies identified, financing mechanisms and calculations on finances/investment, final designs to achieve accurate costing, application of any enforced legislation beyond the eia, etc

    Also wise to engage with funding and regulating authorities to ensure content of feasibility is complete

    you are welcome to make contact for further advice, I am based in South Africa

  8. Due to the the Poles are melting  water will raise and chance to get salt water mixed with waste water will come as most plants are near cost and that gives airiation trouble due to salt

    WW and water supply must be kept seperate from each other in DK this has happened

    Dear Markus:

    A best technical Proposal need accurate information regarding water quality in/out for both drinking and waste water plants. Another important aspect is the financial details.

    I feel your focus must be in presenting efficient, compact technologies requiring space, man hour ,CAPEX and OPEX as less as possible. Say at least 25% less. Better if can be remotely monitored and operated.

    We can help to design, provide, install and on commissioning these systems

  10. I think that your best option is to contact with somebody from a multilateral bank like WB or ADB or some kind of cooperation agencies. All of them have some documents that could be usefull for you at the beginning. Tipically they have this documents as guides for subcontractors and/or partners 

    Sorry my knowledge of Africa experiencies is limited, but I know that there is a lot of experience of this kind of projects in South America for small comunities or areas, The problem is that the information is in spanish.

    Anyway I agree with Mr Cook, "it ​would be ​difficult ​to  ​provide you ​with all the ​details of how ​to conduct the ​full spectrum ​of tasks over a ​computer link"

     

     

     

  11. What type of assistance are you looking for? Are looking for someone to take on the task or assist you in Lagos with the studies. If not, all I can say is that it would be difficult to  provide you with all the details of how to conduct the full spectrum of tasks over a computer link. The first question that needs to be resolved is where is the raw water to be sourced? From past experience in Lagos, (Victoria Island) I would be surprised if you could use groundwater due to saline intrusion. Maybe you could come back with more information. All the best

  12. There are some low cost wastewater treatment options.  However, the source of the wastewater is needed.  Also, the soils in the area would be needed.  Please provide additional information.  The land use in the area is also needed.

  13. There are any number of solutions, but they tend to be expensive.  I'm working with a company that generates energy from ag waste..  Tell me/ tell us what type of wastes.  If it is livestock that's one thing.  If it is chickens, that's another. If it is purely agricultural, that's a third type.

    You will need to have wastewater treatment, and waste treatment solutions for proper waste disposal.
