INTEGRATED WASTE TREATMENT SOLUTION (IWTS)
Adoption of Anaerobic Digestion Systems:
As long standing stakeholders in the Waste Management Industry, we are
aware of the struggles that come with sewage management within and outside
Lagos.
It is in the light of the above that we proudly present for your
consideration a proposal to radically re-orient your sewage management
system and put in place a state of the art technology that is 100% full
proof and in tune with the prevailing global shift toward proper
management of the environment.
The Technology sets out to demonstrate a strong technical capability,
reasonable financial proposal and a documentation of a track record of
relevant experience in the design, construction and commissioning of the
biogas systems.
Kindly find attached in detailed, the scope of activities with its
relevant cost of implementation and benefits among others to facilitate
decision-making.
If implemented;
1. This system will completely solve your sewage system problems.
2. There will be no more EVACUATION of sludge.
3. Create clean and healthy alternative water source to service your green
areas.
4. Produce Biogas (Methane Gas) which could be utilized to power low
mechanical systems and or as direct source of energy for cooking.
5. Allow your facility to live up to the commitment to Style, Class and
Comfort and Clean Environment.
EXECUTIVE SUMMARY
1) Due to the water table in Lagos, location and population, septic tank
capacity may be stretched. Water may seep into the septic tanks;
inadequate size of sewage treatment plant where available will result in
constant and regular evacuation. Most facilities in Lekki corridor,
Victoria Island, Apapa, Gbagada and elsewhere have to carry out onsite
EVACUATION OF SEWAGE TOO FREQUENTLY, with an average of about two trips
per week at a cost of ₦20,000 to ₦30,000 per trip.
2) The phasing out of septic tank handling of sewage in Ghana and Nigeria
is the result of the environmental impacts of inappropriate off-site
disposal of untreated sludge dislodged from septic tanks in both
countries. The lack of third party treatment systems has resulted on the
discharge of septic tank sludge in the country’s wetland and the large
marine ecosystem. Septic tanks have become significant land-based sources
of pollution with implications of poor sanitation and public-health
related hazards.
3) The biogas technology has been selected by clients based on the
benefit/ performance of the technology in most institutions across the two
Countries. The technology has been installed and successfully being used
in reputable Churches, hotels, institutions and shopping malls in both
Ghana and Nigeria such as such as;
a. The Elevation Church Lekki, Lagos
b. RCCG (City of David) Vitoria Island, Lagos.
c. Jubilee House (Seat of Presidency) - Ghana.
d. Protea Hotel Select - Owerri.
e. Protea Hotel Select - Takoradi-Ghana.
f. Transparent Plaza Bayelsa State.
g. Ashesi University – Ghana.
h. Central University – Ghana.
i. Ashaiman Polyclinic - Ghana.
j. Onitsha shopping Mall.
l. Nairabet Head office Igbo-Efon Lekki.
m. Cooper 24 Towers, Ikoyi, Lagos.
n. 8 Block of duplexes at Ikate Roundabout Lekki.
Several animal farms and domestic Homes.
4) The biogas system will comprise of a digester as a primary treatment
for the sewage stream, a secondary innovative enzyme technology for
reduction of COD, BOD, TSS FOG and clarity for the biogas effluent and
the non-sewer wastewater generation, and tertiary treatment by carbon
filters and disinfection before recycle of proportions for irrigation and
ultimate discharge of unused fractions to storm drainage or potential
local farmers for irrigation.
5) The system thus offers a cost effective, climate-friendly and low
impact technology solution for the facilities operations that meets the
3Ps sustainable philosophy (Prosperity-People and Planet).
