During the rainy season, rainwater is collected from the roof of the Mama Betty building, which has a surface area of 600sqm, collecting approximately 30 cubic meters of water per minute during a heavy storm. The rainwater is collected through a gutter and downpipes, located along the rear of the Mama Betty building. The water is stored in eight 12,000-liter tanks in our rainwater harvesting tank bank. The water is used in the toilets of the Mama Betty building and in the garden irrigation system.
We separate all the paper, cardboard, plastic bags, plastic bottles, and food waste. The paper, cardboard, plastic bags and plastic bottles are collected or delivered to recycling companies around Lusaka. The food waste is loaded into JK series composting machines, located in our waste management area. The food waste is mixed with sawdust and turned on a daily basis. The food waste turns into compost within a 4-6 week period. The compost is used in the gardens around Foxdale Court.
