Aktiviti utama yang dijalankan adalah penganalisaan sampel air. Analisis yang dijalankan termasuklah ujian kimia bukan organik, mikrobiologi, kandungan besi dan kandungan organik. Kesemua parameter ujian dikelaskan di dalam kumpulan I, II, III dan IV. Aktiviti lain yang dijalankan ialah menangani masalah kualiti air yang di hadapi oleh pengguna dengan melawat premis berkenaan untuk mengenal pasti punca sebenar masalah.
Pihak makmal turut memberi nasihat dan bantuan teknikal/saintifik kepada pihak operasi, individu dan pihak lain yang memerlukannya seperti pihak istana, sekolah, hospital, perkapalan dan lain-lain agensi, khususnya dalam hal-hal berkaitan kualiti air.
