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

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.
