SMEC adopted a holistic solution that incorporated capacity building, cost benefit analysis and innovative technical delivery. The project interventions exceeded the project objectives and resulted in several notable benefits including:
- Increased system knowledge, including water distribution and critical point layout, which improved accuracy of water balance measurement;
- Reduced water loss through the ability to remotely monitor inflow and reservoir levels;
- Provision of auditable check meters to provide accurate System Input Volume (reduced water purchase);
- Skills development and training of local municipal officials; and
- Community engagement that led to a reduction in consumption and an improvement in meter reading data.
This project has deepened the client’s ability to understand and manage non-revenue water challenges. Rowan Griffioen, Project Director and Non-Revenue Water Specialist said:
As a result of this intervention, the City of Tshwane has already been able to save the equivalent of 320 Olympic-sized swimming pools per year, which can be translated into a monetary savings per annum of over ZAR 8,5-million. Further to this, it has been calculated that around 300g of CO² emissions are saved for every 1kl water leakage reduced which equates to a total of 24 tons of CO² emissions saved per annum.
