The Century City Urban Square (CCUS), a mixed-use development by Rabie Property Group, utilizes treated effluent (TE) from the Potsdam treatment works for irrigation, cooling tower consumption, and toilet and urinal flushing. This strategy, combined with water-efficient fittings and real-time monitoring, significantly reduces potable water demand and operating costs. In 2017, the CCUS consumed 0.18kl of potable water per annum per m2 of Gross Build Area (GBA), compared to 1.09kl per annum per m2 in a comparable development without these resilience measures. The use of TE offsets approximately 44,000 kl of potable water annually, resulting in R2.3-million in water and sanitation savings based on 2021 tariffs.

The South African small scale embedded generation (SSEG) market, dominated by rooftop solar PV, has grown to over 100,000 systems (over 1GW) as of 2020. However, market growth is hindered by an indistinct regulatory landscape and stakeholder uncertainty regarding licensing and registration. The document outlines a tiered regulatory framework based on capacity: systems under 100kW generally do not require NERSA registration (provided local utility conditions are met), those between 100kW and 1MW require NERSA registration, those between 1MW and 10MW require licensing, and those over 10MW require both licensing and ministerial determination. It emphasizes that all grid-connected generation must be registered with the relevant transmission or distribution grid operator, and for systems between 100kW and 1MW, a connection application to the distributor must precede the NERSA registration application.

The document outlines the regulatory requirements for embedded generation in South Africa, specifically focusing on the transition to a 100 MW license-exempt threshold. It details the two-phase process involving connection approval from a licensed distributor (municipality or Eskom) followed by registration with the National Energy Regulator of South Africa (NERSA).

The City of Cape Town (CCT) is transitioning from landfilling wastewater sludge to anaerobic digestion at bio-solids beneficiation facilities (BBFs) due to national and provincial landfill bans on liquid and organic wastes. The CCT generates approximately 199 dry tonnes of dewatered sludge per day, which it currently spends ~R60 million annually to dispose of or apply to land. The city plans to establish two regional BBFs over the next 15 years to produce A1a class treated digestate cake and recover energy and nutrients. Potential circular economy options include agricultural use, energy recovery (biogas, combustion, pyrolysis), and commercial applications like brick manufacturing. Additionally, the CCT is exploring broader organic waste diversion for garden greens, animal carcasses, and household food waste to meet a 100% organic waste landfill diversion target by 2027.
