Water- an added value approach

Manual pumping of water Kitchen Latrine

Farm- irrigation Shower room Storage tanks Hot water bathing

Hygiene

Simple and effective domestic and personal hygiene- hand washing, pot rack and shower bathing

MANUAL DRILLING

Introductory training conducted Five test drill wells in Freetown Rural-paid by

individuals; all functional since july 2013

Drilling method-suction and washing Drilling of 30 metres can be done in two days,

6 drillers

Average cost of a drilled well 30 metres depth

Le 2.5 to Le3 million

TOOLS NEEDED

:

A 4 metre high derrick crane made of iron

bars and fastened with 4 tension rods

lever and shaft, a small stick to pull the rope

and one or two pulleys and a resistant rope .

60 metres of drill pipes = 20 bars, 3 metres

long, and two pieces 1 metre each, with 1 inch

Reinforced nipples, a drill bit , one or two

holders, 7 metres of 3/ 4" hose, and a mud emas pump.

• pipe press to fasten the drill pipe for

screwing and unscrewing its pieces, 2 pipe wrenches, a piece of wire mesh to sift mud, two buckets and a steel brush.

TOOLS AND EQUIPM ENT ASSEM BL Y

EM AS M ANUAL DEEP DRILLING (WASHING)

This drilling method can drill to a depth of 100

metres in soils of fine material which do not contain stones . The drilling diameter is only 2 inches and the average yield of these EMAS wells is 1 litre per Second- 3600 litres per hour.

THE EM AS DRILLING SYSTEM USING SUCTION

thick sand and small stones or pebbles

are encountered

can be used by simply adapting a check valve

below the holder. However if a pebble size greater than 2 cm is found, then bars of a larger diameter are required together with a larger valve.

The drilling liquid should be strongly thickened

to be able to carry pebbles. This is not always possible.

Sanitation

Upgrading, comfort and improving health

Challenges

Coordination and networking amongst

partners and stakeholders

Short project duration (18 months); only

• ne dry season

Servicing customer call across the country-

project locations in only two districts

Transport constraints especially for pipes 6

metres length

Dependency syndrome of Sierra Leoneans-

unwillingness to pay for wash services

Poor town and household planning

Challenges cont.

Difficulty in rehabilitating large diameter

household wells –too expensive for household level

Culture of building very deep and wide toilets Perception - composting toilets, manual

pumping of water is poverty, rain water is not good ; not useful

Quality control monitoring is a big challenge Free Wash services delivered by big

donors/ NGOS/ politicians

Lack of pro-activeness of trained technicians Poor quality materials and equipment-pipes and

tools

Pilot project not clearly understood

Lessons learnt

Big ignorance in sector about rain water

harvesting-soft subsidies for large tanks

Sierra Leone does not lack water; water

resource management is the problem

Women, children, aged and the physically

challenged remain largely marginalized in current WASH system designs-squatting toilets, head carrying of water over long distances

Lessons learnt cont.

Underground water is consistently being

polluted-this may have serious health implications

Water catchment areas across the country

are heavily over exploited and mismanaged

Treatment of water for domestic use can

work best when knowledge is strengthened at the household level

Self supply succeed best where there is

proper policy frame work and a willing leadership direction

Lessons learnt cont.

Profit based approach –more demo. sites due to

financing options e.g. offering pay-back periods, village savings and loans clubs/ osusu

Quality control monitoring-own funds to

strengthen quality control coop.

Use of more local materials and product range

will increase investment

Customer feed back options will help determine

product choice and appro. M arketing strategy

Lessons learnt cont.

Every individual welcomes change that

improves quality of his life-just need right

• ptions and right opportunities and the right

time

One concept direction

Sound health for every one

Effective hygiene Clean water Good sanitation Effective hygiene
