Higher OPEX enables CAPEX savings – an analysis of the cost effectiveness of the Maynilad NRW management project

Abstract

This paper analyses the NRW reduction efficiency gains made by Maynilad based on NRW strategy design and constant improvement using Miya's know how and experience. These different stages of project design and budgets have been analyzed:The initial plans prepared in 2006The final business plan prepared in 2008The actual situationThe results confirm that a holistic, well designed, NRW management strategy and sufficient OPEX budgets allow CAPEX reductions and helps to reduce NRW more aggressively than initially planned.

Non-revenue water reduction strategies: a systematic review

“…A lack of data can lead to misassumptions when managing the WDN (González-Gómez et al , 2011; Rajasekhar et al , 2018; Saadr and Anuar, 2019; Saldarriaga et al , 2010). Furthermore, missing data also complicates water balance analysis, leads to network connection misassumptions and creates challenges in implementing NRW reduction strategies; for example, replacing and upgrading water pipes (Kanakoudis et al , 2013, 2015a; Liemberger et al , 2012). To address these various data-related problems, effective and reliable data management systems must be developed.…”

“…Effective data management is important for tackling NRW problems. The main issues in managing AL data include data handling errors and data unavailability (Bhagat et al, 2019;Hussein et al, 2017;Kanakoudis et al, 2013Kanakoudis et al, , 2015aLai et al, 2017;Liemberger et al, 2012;Yi et al, 2017). Data mismanagement can also affect the availability of data on unbilled authorized consumption, unauthorized consumption and metering errors (Kanakoudis et al, 2013(Kanakoudis et al, , 2015a.…”
