There is an urgent need for innovation in the sanitation sector because the conventional model (toilet-to-sewer-to-treatment) is too time-consuming and costly, and alternatives are lacking. We estimate the challenge ahead by developing scenarios for 60 of the fastest-growing urban conglomerates in the World. We find that the majority would need to build out their sewer systems at a rate that is ten to 50 times higher than the highest rate for any project in the World Bank's database, which is unrealistic. We also carry out a case study of Lagos, Nigeria, which suggests that, in any given year, 14-37% of Lagos State's budget would need to be invested to provide sanitation to the presently underserviced population while keeping up with population growth, which also is unrealistic. Our study provides clear evidence that the conventional model for sanitation is unworkable for rapidly growing urban areas. We conclude there is an urgent need to encourage and fund projects that promote innovations that can tackle the three core challenges: can be built sufficiently quickly, are flexible, and affordable. This is not likely to happen unless the future generation is systematically trained and educated to creatively support innovation in sustainable sanitation.

Below...An estimate of costs of building a sewage system for Lagos in 2015 and 2030 from the paper quoted above

Lagos smelling.

Let me just Waka pass this. We are used to the annoying part of some people

That's why we the wealthy Lagosians are building our Eko Atlantic city so that we will leave y'all to tour smelling mainland

lol.

Na so so high IGR dem Dey announce every year. They leave the basic things to chase shadows.

Lagos gets flooded every year and no government has thought of fixing the drainage issues affecting the state.

They instead use the IGR to buy luxurious vehicles for the few politicians in the executive and legislative arms of government.

Lagos stinks. Even the high brow areas like Ikoyi, Lekki, stinks. I’ve lived in Lagos all my life and I can attest to that.

Improper waste disposal and lack of proper drainage systems in many areas of Lagos contribute to this menace.

The government over the years have also refused to enforce strict laws that’ll combat these menace.

You people will always leave the issues to be focusing on people. You've turned the comments of a Cross River girl to Yoruba vs Igbo tribal war. You'll soon call this guy Ipob even if he may be a Yoruba person. Quite disgusting.
