WATER DRAINAGE PLANNING

3. For newly built industrial parks and urban centers, rain water drainage and wastewater drainage systems must be separately planned and built. For urban centers where water drainage systems already exist and new urban centers, common, separate or semi-separate water systems must be studied and planned, depending on the specific conditions of each urban center.
4. In the following cases, a water drainage planning must be formulated as a separate planning blueprint:
a/ Regional water drainage planning: For a group of urban centers, industrial parks in a province or many provinces, which are geographically close together and have advantageous conditions ill terms of terrain and receiving sources with the possibility for construction of common water drainage facilities and for which a regional construction planning was not or has not yet been formulated;
b/ Urban water drainage planning: For urban centers of grade 2 or higher (for other urban centers if it deems necessary), aiming to detail the water drainage orientations already identified in the urban construction general planning.
5. The water drainage planning formulated as a separate planning blueprint as stated in Clause 4 of this Article must comply with the provisions of Articles 13 thru 20 of this Decree and other relevant provisions of law on construction planning.
6. The Construction Ministry shall guide the cost of water drainage planning formulation.

2. The time for formulation of water drainage planning tasks does not exceed 3 months for an inter- provincial water drainage planning, 2 months for a provincial water drainage planning and an urban water drainage planning from the date the tasks are officially assigned.
Article 15.- Grounds for formulation of water drainage planning
1. The general planning on socio-economic development; construction planning, relevant branch development planning (if any).
2. General planning orientations for development of urban systems and orientations for development of national infrastructure systems already approved by the Prime Minister.
3. Investigation and survey results and relevant data and documents.
4. Water drainage norms and standards.
5. The approved water drainage planning tasks.
Article 16.- Water drainage planning contents

2. Investigations, surveys and assessment of water environment development, related rivers and lakes’ capacity to drain rain water, wastewater.
3. Identification of water drainage basins of the planned area.
4. Determination of basic water drainage norms and parameters, including climatic and hydrological conditions, infiltration coefficient, daily-life water drainage standards, industry, services...
5. Determination of rain water, wastewater drainage volumes.
6: Identification of receiving sources and their capacities to receive rain water, wastewater.
7. Selection of systems for rain water drainage, wastewater collection and treatment
8. Determination of wastewater quality at connection points.

2. A general report covers explanations, relevant documents of legal validity, written approval of the water drainage planning blueprint.
Article 18.- Responsibility to formulate, competence to appraise and approve water drainage planning tasks and blueprints
