Presentation outline

3. What are WOPs?
Water Operators’ Partnerships
(WOPs) are peer-support
partnerships between water and
sanitation service providers
They focus on building
capacity of resident operator
staff, rather than “doing it for
them”. This way, the benefits
last.
They are peer partnerships,
meaning that the support
comes from professional
counterparts with hands-on
experience.
WOPs are carried out on a
not-for-profit basis.

(public) water utilities established in 2005 with
two goals:
1. to contribute to achieving Sustainable
Development Goal 6 of the United Nations
(“water and sanitation for all, forever”)
2. to engage staff of the Dutch water utilities
internationally, as an instrument for capacity
development

• At present 6 out of 10 NL water utilities are
partner
• Staff: 21 employees in NL, 27 project
managers on site, 100 local staff, 250 short
term experts
• Turnover €21M per year
Introduction VEi

7. Approach
Long term engagements (5-10 years) with strong
local presence (Dutch project manager on site)
Objective: improved access to water services, with a
focus on financial sustainability of the water utility
Through:
• Improving working processes in water utilities
• Pro poor investments
• Operational investments
• Attracting external investments
• Influencing the enabling environment

8. Countries where we work (18 countries)

9. Example: 10 years of collaboration with NAWASSCO
• Nakuru: 4th city and one of Kenya’s economic
centres with a rapidly growing population of
currently 530,000 people.
• Approximately 40-50% of the population lives
in low income areas.
• Water company: Nakuru Water and Sanitation
Services corporation (NAWASSCO)

20. Financial analyses of our NRW programmes
Payback period ranges from a 1-2 months (e.g. replacement of a single under-registering meter for one large consumer)
....to 1 year (loss reduction at DMA level i.e. at EUR 30-50 per connection)
....to 10+ years for network rehabilitation (at utility level)
