PROJECT 27 class and client needs . Water demand was calculated based on fixture types and peak demand factors , as per SANS 10252 Part 1 , and included domestic water storage and booster pump specifications . Drainage systems followed SANS 10252 Part 2 and incorporated local design regulations .
Where ablutions were centrally located , special recessed plumbing ducts were designed to connect soil and waste fittings to a single accessible branch pipe . The ducts were filled with river sand to facilitate future maintenance without disrupting the concrete structure . Coordination between architectural design and other services was crucial , especially with limited ceiling void space for drainage , HVAC , water supply , rainwater and electrical systems .
Closer view of the system .
Smart water meters were installed , linked to an online platform for real-time water usage monitoring . The system included irregular flow alarms to detect leaks , contributing to water conservation . Energyefficient DAB Easybox Max booster pumps were specified , with integrated control panels and Wi-Fi for alarm monitoring . The booster pumps could adjust flow rates during peak demand times to optimise energy consumption .
The telemetry system provided comprehensive monitoring of the water treatment plant , including mains voltage , signal strength , water meter consumption , booster pump pressure and graphical representations of key equipment . Tank levels for treated and potable water were also included in the dashboard , allowing facilities management to monitor and manage the system efficiently . The most challenging aspect of the project was the coordination of services in ceiling voids . This coordination was particularly challenging above the radiology department , as no services were allowed over this sensitive area .
The single greatest challenge the team encountered was time . However , because of a strong team and cohesive team work along with backing from suppliers , the building was completed in the designated timeframe . PA
