SLIDE 2

Demonstration: New options, focus on low cost
Training: NGOs.Local private sector

Production,O&M, marketing, ..

SMART Centre

SLIDE 3

Propositions

1 To reduce poverty (MDG 1), it is more cost- effective to invest in self supply than communal water supply 2 To reduce water borne diseases it is more cost- effective to invest in point

f use treatment than in centralised

piped systems

SLIDE 4

New low cost options for

 Wells & boreholes  Pumps  Ground water recharge & storage  Irrigation  Treatment (Household level)  Sanitation

SLIDE 5

Wells & Boreholes

Underlining: Avoids collapsing Manual drilling: Rota sludge to 40 m, Baptist to 80 m

SLIDE 6

 Treadle To 6 m, 1.5 mln. (irrigation) $15-120  Emas To 40 m. 20.000 in Bolivia, $20 - 80  Ropepump To 60 m. 110.000 worldwide $30 - 150  Blue pump To 100 m. 300-500 $2500

Pumps

SLIDE 7

Rope pump cases

Nicaragua: Now 90.000, Cost 3 x less, 90% works Ghana: 80% defect after 1 year.

SLIDE 8

Lessons learned For sustainability:

 Repairability

Affordable, spares available, ownership

 Involve local private sector

Profit based sustainability, create supply chains

 3 C`s of marketing, Cost ,… , …  Simple is not easy

SLIDE 9

Groundwater recharge & Storage Tube recharge; Cap. 10-100m3, Cost $5 -10

Wire cement tanks Cap 1 - 50m3, Cost $20 - 30/m3

SLIDE 10

Sanitatation & Hygiëne

US slab ; Urine separation use for fertiliser Wash bottle: Families copy it, idea for schools

SLIDE 11

Point of Use water treatment

Desinfection: Dispenser,Aquatab, Watasol,Plation,… Filters: Pot, life straw family, Swach, Siphon

Bottom line; new low cost Solutions have much potential

Bacteria in wells?

HWT cost 0,1 to 1 $/cap yr

Arsenic, salt water?

Collect rainwater , Cost 20—30 $/m3

More water?

3R, Retention, Recharge, Reuse
Hand drilling, locally produced pumps

SLIDE 14

Scaling up?

Awareness, safe water = money

50% of hospital beds, waterborne diseases. Nicaragua; 1 mln $ in ropepumps increased GNP with 100 mln$. At household level; benefit

f treatment up 60x investment. Role of NGOs , goverments

Improve suppy chains

More products, train local private sector. Basic water skills curriculum

f vocational training, knowledge centres, Smart centres,

Payment options

No free gifts expet for emergencies. Use subsidies for awareness, supply chains Ideas of 300in6

SLIDE 15

Effect SHIPO SMART centre

 20 trainers from 6 countries  12 private pump producers, well drillers  4000 rope pumps, 3500 wells, 400

boreholes, 15.000 water filters

 Cost reduction for water 40$ to 15$/cap
