Hi all,

I am fully convinced beyond any shadow of doubt that the leaders we have are more of clowns and knows very little of what they are required to do. After the energy sector,now it is water sector which is now reeling under the weight of myriad problems ranging from lack of water to the mismanagement of the little that is available…..you see Chality Ngilu stands up and says that Kenya is the most water-poor country in the world and blames the situation on drought and illegal connections. The following day her junior officer Permanent Secretary Engineer David Stower opens his baggy mouth and tells us that the current shortage of water being experienced is due to the drought..what in God’s name are these two idiots treating us to??? The usual sparghetti talk??? Drought has got nothing to do with the current acute water shortage as explained below:

Let us first briefly examine the status of the existing water supplies to Nairobi:

1. Ndakaini Dam

The dam was commissioned in 1990 and is located in Thika district of Central Province. It is the largest of the four Nairobi water sources (supplying 84% of the water consumed in Nairobi) with an installed capacity of 70 million m3 deriving its replenishment from river Chania whose source is in the Aberdares. The designed daily out flow is 440,000 m3 but under normal conditions the extraction rate recorded at the Ng’ethu Treatment and Distribution station is 376,000 m3. This translates into an 85.5% utilization.
As at August 2009,the dam was only 36% full i.e 25 million m3. Under normal operating conditions it would take just 66 days to empty the dam assuming that there is no water flowing into it. The current inflow or rate of replenishment is only 21,000 m3 against an outflow of 86,400 m3. The nett outflow is therefore 65,400 m3. Assuming the current conditions persist and that the inflow and outflow rates are maintained,the dam will be empty in 382 days! The dam was constructed to service the Nairobi water needs at its (dam’s) peak upto 2010 if then the flow of water into the dam continued uninterrupted. Additional capacity was to have been developed by the year 2005 to maintain the dam at its peak. A proposal was made to link the rivers Maragwa and Mathioya to the dam through a tunnel. Nothing has been done to date.

2. Sasumua Dam

The dam was commissioned in 1956. It is located in Kinangop,Nyandarua South in Central Province. The dam supplies 11% of the water consumed in Nairobi and has an installed capacity equal to 16million m3. The dam draws its water from streams emanating from the Aberdares forest. When the dam was first constructed it was meant to serve the white settlers in upper Nairobi,that is Lavington,Hurlinghum,Westlands,Ngong Road,Langata,Ngumo,etc. The designed daily output of the dam is 59,000m3. And the output recorded at the treatment works is 41,000m3. This is equivalent to 69.5% utilization.
As at August 2009,the dam had only 4million m3 of water,i.e 25% full. The dam was badly damaged by floods in the year 1999 and it is currently undergoing rehabilitation.

3. Ruiru Dam

The dam was commissioned around 1953. It is located in Githunguri subdistrict of Kiambu District in Central Province. The dam is fed by river Ruiru which has its source in the Aberdares forest. The dam has an installed capacity of 3million m3. The design extraction capacity of the dam is 22,000m3 per day,but the recorded output at Kabete Water Treatment Works is 21,000m3. This is reflecting a healthy utilization of 95.5%.

4. Kikuyu Springs
This water supply was constructed in 1906 by the Imperial British East Africa (IBEA) and was later sold to Nairobi Municipal Corporation in 1922. The installed capacity for this water supply has never been quantified. It has design extraction capacity of 4000m3 per day and the average recorded at the water treatment works is 4000m3 per day meaning that it is utilized into its full capacity.

The Picture

At independence Nairobi was receiving just about 66,000m3 per day which by any standards was more than enough as the population was very small,about 300,000 and the average daily demand per person was 0.22m3 or 220 litres per day.
As at the fist census carried out in 1969 the population of Nairobi was about 520,000. At this population the water was still abundant . The average daily demand per person stood at about 200 litres.
Ten years later in 1979 the population had risen to about 800,000. The existing water supplies were experiencing the demand pressure because the few water boreholes which had been sunk to supplement the main supplies could not completely eradicate the shortfall. With a demand of over 180,000m3 and a supply of only about 100,000m3 the stage was set for an early sign of crisis. The amount of water available per person was only 125 litres per day. So some areas mainly Langata and Eastlands started having some water problems of occasional unofficial rationing which was just mild.
Ten years later in 1989 the population and risen to about 1,400,000. The water demand in Nairobi stood slightly higher than 320,000m3. The then existing supply could only satisfy just about 120,000m3. The average amount of water available per person was 86 litres per day. With this scenario a half of Nairobi was not receiving adequate water as per WHO basic requirements. Apart from Lang’ata and Eastlands many other suburbs were sucked into the water don’t haves list.
Ten years later in 1999 the population had risen to about 2,200,000. The water demand was then at about 600,000m3 against a supply of about 450,000m3. The sharp rise in demand was because some other areas outside Nairobi started getting connected to the Nairobi supply. These areas include Athi River,Kitengela,Mlolongo,Ruai,Rwaka etc. At this time some Nairobi suburbs could span upto three weeks without a drop of water and again the main casualties were Lan’gata,Otiende,Kibera,Kariobangi,Umoja,Donholm,Savanna. A chunk of the available supply went to these peri-urban areas leaving the genuine Nairobi residents with very little water. The daily water availability stood at 130 litres per person. The improvement here was due to the commissioning of Ndakaini dam.
Come 2009 and the situation is a full blown crisis. The current daily demand from a population of 3,000,000 plus another approximately 3,000,000 from peri-urban areas is standing at about a 1,000,000m3 and the supplies are already stretched to their limit of 450,000m3. And is meant to serve close to 6 million people!!! The daily water availability stands at 75 litres per person!!! Against a satisfactory daily demand or requirement of 200 litres per day!!! What I mean here is that the existing water resources cannot even satisfy just a half of the Nairobi’s current demand if they operated at full output capacities!!!

The Situation

It is really chilling to know that at the moment we have actually run out of water completely!!!...reason… as per the demand of 1,000,000m3 of water,for a population of about 6,000,000,the average demand per breathing person is 0.17m3 or 170 litres per person per day.
Under the prevailing circumstances,the gross output from the supplies is a paltry 150,000m3 per day serving the same population of 6,000,000. This means that to each person only 25litres per day is available!!!!!...just one 25litre jerrycan!!! With only one jerrycan of water per day per person Nairobi has completely run out of portable drinking water…this is a disaster!!!
It can be clearly seen that the amount of water available per person has declined through the years because there has been no expansion of the existing water resources and no new ones have been developed between 1956 and 1991 when the Ndakaini dam was commissioned and after 1991. In post independent Kenya only one water resource for Nairobi has been developed.
The only time that the Nairobi residents enjoyed water in abundance was before 1979 and between 1991 and 1999 where the daily water availability per person was above 100litres per day!!!

Thanks for your informative post yet again. Kweli sisi waafrika we have a huge problem. We can't even plan for our very basic needs! Are there studies done as to where more dams could be built?

Thank you very much,this shows how our leaders are like. Water a very important part of life,no water,no life! FACT, Yet people have been sleeping in their jobs,their perfomance is not being monitored. The ministry of water ought to have alerted the govt long enough,they should have been very forsighted we know people migrating to urban areas the number increases. Measures ought to have been taken to create more dams to make sure the supply is maintained,but since the colonial days and when we took over we utilized what our colonial masters left us with but because we dont think and we get involved things that are not important to the common mwananchi here we are water is running out and the vice president residence is costing 380million!!! This is what is called africanism!!

We dont plan,we have no disaster recovery measures in place for anything,whatever the british left us is what we've been using and the social services have not been expanding proportionally to the population grownth. The current census being done you wonder what they will do with the figures,they will just sit on them or use them to persuade donors to give them funds which end up in a few bellies! instead of addresssing critical issues,its not only water but same thing with electricity,

Roads is another thing,the roads we have are what the brits left us,from the year 2000,there have been an average of lets say 200,000 new cars every year and no roads,you wonder why we have un ending traffic jams and its not going to stop there im telling you. The only positive thing is the main highyway like msa-nairobi raila tried to engage china road works to have it done and now it looks better but before then it was all corroded with huge pot holes on highway in some parts the tarmac could hardly be seen and its a highway linking msa and nairobi!

The Govt is full of jokers and our politicians have really really let us down big time yet they still hang on there to benefit themselves and not the people they claim to represent. Its sad in deed,we have a decomposing judiciary system which reeks of corruption to the heavens!

We wont get anywhere anytime sooner not with these kind of leaders and they get recycled in every corner

SK is too small for this. Like I urged you with regard to the post on electric energy generation you ought to have this published in the press. A small step but it might just arouse some sleeeping politician or bureaucrat!

@ mpenzi,

i hope the pig called chality reads SK to fully understand the extent of the problem...never mind i hope a good guy at SK will copy and send the article to the press...i have already forfeited the copyright hehehehe.

@ all,

if the situation continued like this sooner or later we will start a real physical fight amongst ourselves not any different from the ones fought between the nomadic clans over issues of pastures and water....simply put,i go without water in Nairobi just because a guy in Kirigiti Kiambu is drawing so much of my water or water meant for me or a guy in Mlolongo has been connected to our distribution network and does not deserve it....you get the drift

Kenya are a country of shortages,1. Power rationing,2. Water shortage is here 3.Some kenyans are starving,4 now i'm reading on daily nation that cooking gas has gone out the window. Meaning even those in towns are bound to even if they have food!

Why can India & China with 1bn+ people with sijui how many tribes & religions & poverty still manage to provide enough food & water to the majority while the bastards here can't or wont do their basic jobs???

....and did i hear that there is already a looming confrict amongst neighbours in the leafy Karen over water....the genesis of the problem is the sinking of boreholes. in the eighties there was a strict rule that bore hole sinking should be spaced at a distance of not less than 800m..

the reason for the 800m spacing rule is that sinking a borehole at a distance less than 800m will just increase the chances of extracting water from the same aquiver...this is exactly what has happened in the Karen with boreholes being spaced as short as 80m!!! the heavy extraction has caused most of the original boreholes to dry up and new boreholes being sunk to more than 300m to the water table!!! what to do??? the neighbours do not want each other to sink any more boreholes and yet they dont have enough water...it is getting really nasty!!!

Kenya at the rate its moving we shall have severe problems as if the problems are not serious enough,impunity,corruption every corner and its worsening day by day. As it is at the moment its 'everybody for themselves,God for our souls'. They are really shafting the country these rogue politicians!

@ Jaheim,

i was trying to think hard about the CDF...if each constituency receives on average ksh 150m annually. we have 7 constituencies in Nairobi whose aggregate amount is ksh 1.05b annually. Supposing the government froze this CDF for the entire Nairobi for three years. this would construct a 10million cubic metres dam. I believe Nairobi's water problems would be reduced by 75% if not for the following 3-5 years!!!! within that time more reasources would have been developed...

we lack leaders with a vision...when are we going to get them!!! after a thousand years???

You've said it,how difficult is that?? We not only lack leaders with vision,but INTEGRITY as well. I did observe sometimes back when i was in kenya,the CDF funds do very little in running the actual projects they are meant for or the ones proposed,not only that,the most shocking of all is the fact that these same politicians in the constituencies do give tenders to companies they own or owned by friends hence they get a cut out of it. It does not end there though,they make sure they get 'back kicks' by lobbying for certain tenders to some firms.

I was astonished by this,the entire system needs an overhaul big time! The ones who really suffer the consequences are at the bottom of the pyramid.This Grand corruption diverts resources from the most pressing needs,and those needs are always found at the bottom: basic healthcare,education and security. Every time we pretend to export gold,or buy phantom equipment for our security agencies,we twist the neck of our own economy. But only the poor are left gasping for breath.

At this rate Nairobi will be a nightmarish place to live in within a decade,water conflicts will be a reality and when buying or building that home,cast an eye into the future,what appears golden now could end up a semi desert.Laws to make it compolsoury for residences to have water harvesting facilities should be in place by now as the goverment seeks ways to build bigger dams,but with our lot of politicians your guess is as good as mine.

see it through my lens?

Our new maid went back home to ukambani having received her 3k first month salo. She arrived at her place to find her children having gone without food for 3 days.

To understand how desperate she was.... this is a mother whose last born is only 2 yrs old. She has never worked as a hse help and has never left her home nor has she ever seen nairobi.

Now when her neighbours heard of her arrival,they all came to her asking her to give them something small as their children were dying of hunger. She says that she even had to share the maize she had bought for her family. She spent all the money she had and almost lacked fare to come back thanking us for the extra 300 bob we gave her for fare.

Now imagine the kind of life they are living there. One person from their village goes to nairobi and they become the saviour.

If i was able i would pay her more I would.

What i wonder is,do these pple have an MP? If so,does he know that his pple are living this way? What is he doing to help them?

\The fact is once a person becomes an MP,they first move away form their constituency to go live in posh surburbs in nairobi,convenientlly away from his constituents and their problems. I think it should be a rule that MPs should reside at their constituencies. It beats sense why a North easter MP should be given transport allowance TO their constituency instead of FROM. Afterall he should be living in his own constituiency an work at development and only travel when there is need and parliamentary debates.

Tuamke Kenya. Do we Africans have to be colonized to develop?

Nice one kagizzard...a slight correction,ndakaini dam is in Gatanga district and is fed by 5 rivers/rivulets n I think chania isnt one of them,but its waters r still pumped to ng'ethu....Things r elephant.

The only reason why some people are still alive is coz its illegal to shoot them!!

Well,u shud be congratulated for providing a job lakini I think (I may be wrong) 3k/month is below the minimum salo per govt laws. And to think I often use more than 100/- per day just on internet access...

___*** As a Kenyan,I am frustrated. People say don't complain but do something... I try daily lakini people are always pulling you down. From the ma3 who wants to kill you to the muggers to the folks who want kitu kidogo for the most basic services...

Thanks Kaigangio

The signs of disaster in water,energy,food,shelter etc. have been with us for ages.

Lets call a spade a spade and indulge in self examination. We are the problem. Who voted for these 'leaders'? We never vet them,preferring to vote on tribal considerations and bribes dished out rather than on issues and merit. In addition,we never hold them to account as they plunder our taxes for political and personal gain while selling the line 'funds are not available' or all sorts of excuses.

The posts in January to February 2008 after the 2007 elections demonstrate how polarised we have become,even in enlightened circles such as SK. We were ripping each other left right and centre for 'leaders' who have no time for our problems.

It is plain and simple,unless we start voting on issues collectively and demanding for results,this country is going to the dogs.

Rain water harvesting is the answer (though no rains now). If each home had a reservoir tank to harvest every drop of the rains each year like I have seen it done successfully in most of Malawi and Jamaica,then would not heavily rely on the dams but rather have them as supplements to our water needs.
