I think that the short term vision included improvement of water quality, augmentation of wastewater collection capacity from present 50%, planning for durable water pipes and wastewater collection system, enhancing regular maintenance and checking, periodic monitoring of water quality in rivers and canals were addressed. To augment integrated water management and promote awareness in water sustainability in commons, incentives for wastewater reuse were envisaged. To integrate vision, coordination between master plans and utility master plans are needed to be planned in accordance with Bangkok city plan. Promotion of separate sewer network in place of combined network, collaboration with NGOs (Non-Government Organizations) by funding/sponsoring to promote environmental education among the masses, collaboration with religious/social entities for promotion of water conservation, treated wastewater, and efficient demand management for water sustainability, were addressed; To improve urban governance and project finance, single point water charges by including water supply and wastewater treatment charge to improve willingness to pay were proposed.
For the long term plan, Utility Identity Number (UIN) and integrated water taxation in a phased manner were introduced. Project UIN is conceived as an identity card distributed to individual household, which would include household income, IT return, number of household etc. The revised water taxation includes water supply, waste water recycling charges. The taxation depends on cross subsidy mechanism where the richest SES would bear a partial of the cost of poorer counterparts.
