| Summary: | The existence of sustainable development plan inkapuas coastal areas toward Pontianak Metropolitan Cities, requires a decent source of raw water in terms of quality, quantity and continuity according to national standards. In terms of quantity, availability of raw water is quite abundant, but in terms of quality, raw water source is threatened sea water interution in normal and dry years. This study discusses the hydrological regime for the reliability of raw water source (quality and quantity) of interbasin Ambawang River Landak River (Biyung) were selected as new raw water source for drinking water infrastructure development Regional Pontianak. The results showed that Ambawang River periodically affected by tidal and seawater interution, so the dam was built to break salinity. While the Landak River (Biyung) has a random discharge and is influenced by rainfall. The result of the division of discharge Discrit Markov against salinity values showed that, the highest salinity occurs in dry climates, dry month and daily discharge dry where the amplitude tidal estuary maximum. Pontianak Regional raw water needs of 4.6 m3 / sec in the 2030, while the used discharge for the allocation of drinking water a debit 20 years of dry, dry R20 on the River Ambawang of 12.05 m3/sec, so the 2030 needs raw water Regional Pontianak can be met. Short-term SPAM development strategy 2015 conducted by PDAM Pontianak revitalization and construction of dams and channels suppletion. The development of raw water transmission network in the area of Regional Pontianak can be implemented to meet the medium-term target for 2020, while the long-term target of 2030 made Ambawang reservoir management and development of centralized SPAM integrated with the old system. <br />
