Describe WOPs activities
September 2008
Facilitated by USAID, two Ranhill key personnel visited Surabaya to assess the existing water supply operations and distribution systems, prepare recommendations to better manage pressure, and participate in initial discussions on the twinning partnership’s objective, expected results, and required resources. USAID moderated discussions to confirm the goal of the twinning, define duration, and determine inputs needed to achieve the goal. At the end of the visit, Ranhill gathered information on the supply pipelines, pressure monitoring practices and results, and developed preliminary action plan to improve pressure distribution, forming the basis for a 9-month joint work plan.

October 2008
In a follow-up visit, three Ranhill experts conducted a more thorough analysis of Surabaya’s water distribution network. The experts worked with the PDAM staff to review the network modeling and GIS mapping systems, collected detailed information on main supply lines and water production capacities, and refined the action plan into a joint work plan.

December 2008
PDAM Kota Surabaya and Ranhill signed a Memorandum of Understanding to commit to implement the joint work plan and contribute resources in meeting the twinning objective of enabling continuous water supply. Following the signing, two Ranhill experts trained 11 PDAM staff on best practices for monitoring real time pressure using data loggers. Ranhill provided guidelines on locating pressure monitoring points across the city, as an initial step to collect baseline information, operating data loggers, and analyzing results. Ranhill also introduced local vendors supplying pressure management equipments, such as the pressure reducing valves, to the PDAM to begin looking into capital investments for improving pressure management.

February 2009
Two Ranhill staff worked with the PDAM in verifying the pressure monitoring process and in analyzing the data captured. Partners identified new service areas with low pressure and selected one pilot area to exercise pressure management practices. Ranhill also helped the PDAM in reviewing and selecting equipments required to implement the pilot activities.
On a short trip, three senior Ranhill experts discussed with Surabaya areas where low water pressure is occurring and did a rapid field assessment. Ranhill also provided tips on pressure data collection and analysis, which the PDAM is continuing to collect for baseline. This monitoring visit was intended to ensure the PDAM will adequately gather information for subsequent activities on pressure zone set-up.

July 2009
Practitioners from Ranhill Utilities visited Surabaya to provide technical advice on delivering continuous water supply to 4,400 households through improved pressure management. Ranhill experts gave hands-on training on valve operations, pressure zone establishment and data monitoring. The activity complemented past training events which Surabaya has adopted

August 2009
From August 11-14, 2009, 5 delegates from Surabaya’s water company in Indonesia took part in a technical visit to Ranhill Utilities in Johor, Malaysia, to support Surabaya’s efforts to provide a continuous supply of water. During the visit, Ranhill experts highlighted their field techniques to manage water supply pressure and conducted a short training on pressure data analysis and zone isolation. The utilities also jointly finalized an action plan to increase water pressure and thus enable continuous supply in a pilot service area in Surabaya

RESULTS

Describe the overall results
Through the partnership with Ranhill, Surabaya will be able to improve water supply service to 4,400 households in 2009
