National technical regulation on surface water quality

1 GENERAL PROVISIONS 1.1 Scope of regulation

1.1.1 This regulation stipulates maximum value of surface water

quality parameters

1.1.2 Subject of application:

- Assess and manage surface water quality, as a basis for the

protection and use water properly

- As a basis for the establishment, approval of water use planning

according to the identified uses

- Assess the conformance of surface water quality for the approved water use planning

- As a basis to control the reception of waste resources, ensure surface water sources are suitable for use

- As a basis for the implementation of measures to improve, restore water quality

1.2 Terminology

Surface water is water flowing through or deposited on the ground,

rivers, streams, canals, slots, canals, lakes, ponds, marshes

2 TECHNICAL REGULATION

Maximum value of surface water quality parameters are specified in Table 1

Remark:

The classification of A1, A2, B1, B2 for surface water sources to assess and control water quality the various purposes of water use, sorted

by descending quality level

A1 - Use for domestic water supply purposes (after applying conventional treatment), conservation of aquatic plants and for other purposes such as type A2, B1 and B2

A2 - For the purpose of domestic water supply, but must apply appropriate processing technology or the purpose of use as type B1 and B2

B1 - For irrigated agriculture, irrigation purposes or other purposes which require the same water quality or purposes as type B2

B2 – Waterway transport and other purposes with low quality of water requirements
