Results and Benefits of PMA EstablishmentWater Network – in coordination with Maynilad Business Area and the NRW Unit, initiatedthe Pressure Management Program. After around 1 year of existence, it has already madeits spot as one of the best tools in managing supply and pressure in Maynilad. Moreimportantly, pressure management has helped Maynilad in weighing considerationsin NRW and in addressing concerns in BV.Figure 9. Recovery and location of established PMAs in Maynilad as of end of August 2011As of August 2011, through establishment of PMAs alone, Maynilad has recovered11.86 MLD worth of potable water. In addition, with the use of pressure management asa tool in network control, it has also helped Maynilad in the following:• Mitigating high transient pressure• Minimizing breakages in lines• Eliminating excess pressure during night time• Bringing down MNF• Maximizing flow during peak hours• Maintaining CP pressure at Maynilad service levelTo date (September 2011), there are 281 established PMAs in the whole concession areaof Maynilad. These PMAs are continuously monitored and analysed for possible supplyand pressure variations.
