Directorate Water Supply) – Government of Timor Leste, , 3BESIK (Water, Sanitation and Health in the Community),


1. Contexte/Context

• Indonesian Annexation: 1975 – 1999

• Infrastructure destroyed in 1999

• Free democratic state: 2006 – 2016

• Donor and Govt. capital investment in water systems: 2006 – 2016


2. Electric pump systems - definition

• Electric

(mechanised)

• Grid or solar

connection

• Community,

clinics & schools

Government / Partners Community


2. Electric pump systems - Problem

• Rural water supply systems are relatively easy to construct, but more difficult to manage effectively.

• Systems which include electrical pumping are particularly vulnerable to failure and long periods of down-time.

• Pumped systems are increasing in number as most springs and surface water sources have now been developed.


3.Objectifs / Objectives

• National pump system asset registration

• Assessment of BESIK capital maintenance

• Analysis of Cova Lima/Ainaro (O&M) trial

“Service Provider” contract

• Training a team/s of pump system technicians

for DNSA

• Technical design standards and O&M tools


4. Asset Registration - Method

• Photos

• SIBS data link

• Functionality


4. Asset Registration - Results

• Beneficiaries: 147,000

• 27 % systems not

function (Beneficiaries:

51,000)

• 78% Electrical

connection, 20% Solar,

2% Ram pumps


5. Capital Maintenance Programme

Method (2012 – 2015)

• BESIK (AusAid) funded

• Two rural pump system

technician

• Reactive maintenance

• 54% site visit success

rates

• Team based in capital



Results (2012 – 2015)

• 134 site visits to 73 locations

• 427 maintenance actions

performed on 73 systems

• 41% control panel (electrical

faults)

• 28% pump faults

• 9% poor discharge construction

• 22% site surveys


• ~ 38,000 beneficiaries

• Programme cost: $103,100

• Av. Annual cost/system: $590

• Av. Annual cost/HH: $14

• Av. HH contribution/annum: $6


Costs (2012 – 2015)



Costs (2012 – 2015)

• ~ 38,000 beneficiaries

• Programme cost: $103,100

• Av. Annual cost/system: $590

• Av. Annual cost/HH: $14

• Av. HH contribution/annum: $6


6. Private Service Provider Contract –

Method & Results

Delivery

(Dili)

Per Diem

• 12 sites (2 years)

• Private contractor

($37,700 contract value)

• Av. $2300/pump system

• Av. $21/HH/annum

• 92% functionality

8. Training Programme

• 15 new pump technicians

• Training duration: 6 months

• Overall costs: $87,000

• Technical inputs from Lorentz and Grundfos staff


• Revision of Rural Water Supply Guidelines

– Electric pump system designs an specifications

• Energy consumption analysis (TOTEX)

– 95 sites analysed for energy consumption with energy cost (production) ~ $450,000 pa

• Strategic costing tool- projected cost tool urban/rural

– Investment in CapManEx vs. CapEx

– Tariff, population, coverage modelling

9. Guidelines and Analysis Tools


10. Leçons apprises / Lessons

Learned

• Understanding how many systems, functionality

and failure modes important

• Accepting the need for more human resources

and budgeting realistically

• Advocating for the long term benefits of

investment in O&M

• Evidence based decisions key


11. Conclusion

• Down times up to 2 years and more

• Two capital maintenance models trialled with

increase in functionality from 63% to maximum

78%.

• Private partnerships need nurturing & monitoring

• Donor funding volatility and political change

disruptive service delivery

• Government ownership of complex rural

systems strongly advocated
