USE OF WATER RESOURCES
PKOP LLP has developed and implemented water protection measures of PetroKazakhstan Oil Products LLP (Basin Agreement for the Restoration and Protection of Water Bodies of the Aral-Syrdarya Basin).
Technical water supply at the refinery is provided from three water supply sources:
The second source of water supply for technological needs of the refinery is water from the refinery own wells (own water intake), according to the Permit for production of industrial and technical underground water № KZ81VTE00161888.

Water disposal at PKOP LLP:
Production facilities of the refinery have the following sewerage systems: household and domestic sewage system, production and storm waste waters. The refinery has two production and storm waste water system:
- I system - for disposal of oil-containing neutral production and storm waste water.
- II system - for disposal and treatment of emulsion and chemically contaminated waste water containing crude oil, oil emulsions, salts, reagents and other organic and inorganic substances.
Neutral oil-containing effluents from new process units, such as bottom water, washing water, storm water, process condensate is discharged into the first system of production and storm wastewater. Chemically contaminated effluents, blow-down effluents, ultra-filtration wastes from water treatment plant, and stripped acid waste water are discharged into the second system of production and storm wastewater. Waste water of I and II systems undergo separate parallel mechanical and physical-chemical treatment in grit catchers, oil traps, radial-flow settling tanks and flotators. The treatment facilities are designed for treatment of effluents contaminated with oil products and suspended substances.
The receiver of production waste water of the Refinery PetroKazakhstan Oil Products LLP is an evaporation pond located in Ordabassy region of Turkestan oblast. The site of the evaporation pond is a land plot 13-15 km to the south-east of Arys. The site is located 5-7 km to the south of Yntymak village in sparsely populated desolate area. Three different-level evaporator ponds are separated by uniform bulk earth dams. The area of water surface of evaporator ponds is 78.22 hectares. Including the first pond – 16.0 hectares, the second pond – 25.72 hectares and the third pond – 36.5 hectares.
