Design, Supply, Test And Commission A Containerized Package Water Treatment Plant For 50m3/H At Mazabuka – Kaleya.
Zambia Sugar is the largest sugar producer in Zambia and the largest single cane sugar mill in Africa. , located in the south-western region of the country alongside the Kafue River, it cultivates sugar cane and manufactures Vitamin A-enriched raw and refined sugar under the White spoon brand name for local consumer markets and industrial customers. The company also produces speciality sugars for export to the EU and syrup for local consumer markets. It also has an active social investment programme targeting health, education, sports and culture. Zambia Sugar offers a wide range of education, health and social amenities to its staff and the surrounding communities which include but, are not limited to, medical services, schools, sports and recreation at the Nakambala Estate.

Zambia is a country that is somewhat known for its lack of good quality drinking water. Statistics state that over 6.3 million people in Zambia do not have access to clean water, with over 11 million people with no proper sanitation and children under 5 years dying due to water-borne illnesses. The Zambian community was in need of good quality potable water, they approached Watericon to design,supply,test and commission a containerized package water treatment plant for 50M3/H at Mazabuka – Kaleya. The treatment would have to handle raw water from Dam 22 of which the quality was unknown and the produced treated water would meet SABS or WHO standards within the limits of TDS of the raw feed water.
Water icon designed, supplied, tested and commissioned a containerized water treatment plant to produce potable water with a flowrate of 50 m3/h to supply total of 6635 people. This plant comprised of a chemical dosing system, settling, filtration as well as a Reverse Osmosis plant to produce effluent of good quality. The final step being disinfection.
The water treatment plant consisted of the following:
- pH correction of feed water
- coagulant/flocculant dosing
The process starts off at the raw water tank, then it then sent to the chemical dosing stations that includes flocculant addition, pH correction as well as disinfection. After dosing the water goes to the reaction columns and flocculation columns and then it is sent for settling in our specially designed settlers which promote sludge concentration and ensures minimal water loss during de-sludge. The final destination for the water is the clean water tank.
The zambian population has a supply of good quality potable water this is according to the 2016 Annual report released by Zambia sugar . Zambia sugar is noted to provide water to a population of 16 000 on the estate and further supplies bulk raw water to the Southern Water and Sewerage Company (SWASCO) which in turn supplies clean and treated water to the entire Mazabuka town. The plant that we designed provides access to clean water to at least 42 % of the above mentioned population. This decreases the risk of waterborne illnesses, it restores the human right of people to safe water and sanitation and it improves the education system because the water shortage crisis in Zambia had negatively impacted the education system.
