Sub-metering for tenants |
|
* |
|
Sub-meters are used to measure water consumption for all tenants |
|
All large users measured. Non metered tenants prorated. |
|
Most of tenants are sub-metered (95%). In time all tenants will be sub-metered |
|
In phase-1 only large users are sub-metered. Phase-2 all tenants are sub-metered |
|
Large anchors, restaurants and hair dressers are sub-metered |
|
Sub-meters will be installed to monitor water consumption for all tenants |
|
Large anchors and restaurants are sub-metered |
|
Water consumption for anchors, restaurants and hair-dressers is measured |
|
Water consumption is measured for all tenants, common areas and toilets |
| |
Fire-system water consumption |
|
All pumps metered. Alarmed if pressure drops occur |
|
Fire-water consumption is not measured or alarmed. Measures to be implemented to control use |
|
Fire-water metered. |
|
All pumps metered. Alarmed if pressure drops occur |
|
No metering occurs. Options are to be explored |
|
Options are to be investigated related to monitoring consumption |
|
All pumps metered. Alarmed if pressure drops occur |
|
Currently metered |
|
No metering occurs. Options are to be explored |
|
Daily checks are undertaken to ensure that abuse does not occur. Consumption is measured as part of the common area consumption |
| |
Waterless urinals and dual-flush toilets |
|
To be implemented as part of 2014 toilet upgrade |
|
Duel-flush toilets are used in phase 2 |
|
Dual flush toilets in all ablutions |
|
- |
|
- |
|
Waterless urinals are used in public bathrooms (retail and office areas) |
|
Dual flush toilets will be installed |
|
Scheduled as part of bathroom upgrade 2013 |
|
Dual flush toilets are used |

Water leak detection |
|
Random readings taken at incoming feed at different times to assess consumption and thereby detect possible leaks |
|
Options to be investigated |
|
Weekly readings taken and sent to utilities company to check for abnormalities |
|
Daily council water meter reading are taken (at different times of day) |
|
Random readings taken at incoming feed at different times to assess consumption and thereby detect possible leaks |
|
Options to be investigated |
|
Best practises will be adopted in the completed building to detect leaks. All water and plumbing lines are being replaced |
|
To be investigated |
|
Weekly readings are taken at incoming feed - leaks have been detected and repaired |
|
Random readings taken at incoming feed at different times to assess consumption and thereby detect possible leaks |

|
2 boreholes used for irrigation |
|
