Improved hydraulic management of the Dili water supply system and more efficient tertiary distribution

The project will (i) check and refurbish and replace and install up to 35 primary and secondary distribution master meters (ii) check and replace as necessary up to 51kms of tertiary distribution water pipes (iii) check and replace as necessary up to 2,950 household meters and 240 commercial and bulk meters; (iv) check and normalize as ncessary up to 5,100 household connections and up to 170 commercial connections (v) relocate up to 1,700 existing water service connections to allow the disconnection of up to 7,000 linear meters of old asbestos cement and other water mains; (vi) install up to 88 new stop valves; (vii) refurbish or replace nine chlorination dosing units at deep bores; (viii) undertake practical minor repairs to support operational efficiency and safety; (ix) train and support a Dili water demand management task force; (x) establish and give in-field mentoring for three leak detections teams; and (ix) train six subzone caretakers.

1. Water losses reduced and controlled in three target zones.

2. Visible leaks reduced; practical improvements made; stop valves refurbished, replaced, or installed to allow the better management of the system; and commercial customers metered in all Dili water zones.          

3. Skills of DNSAStechnical and O&M staff upgraded in leak detection, leak reduction, and subzone management (the Dili Water Supply Performance Improvement TA will provide formal and on the-job training for (i) NRW, (ii)

   network modeling and drawing office management, (iii) meter management, (iv) customer service
