Received our second building variation today due to removal of the “Fully Charged Water System with Water Tank” (refer to Water tank tanked ). Represents a bit of saving in the “Mandatory” costs for us.
The hydraulic report for our construction has returned with the conclusion that a fully charged water system is not required. During the tender stage, a requirement was added to our contract that a “Fully charged system including a water tank supplying the toilets” was necessary not so much due to the local water infrastructure, but as a council sustainability requirement for new dwellings.
In light of the report, Carlisle inquired as whether we still wanted the water tank. I was somewhat confused as I was still under the impression that there was a sustainability requirement. I went online and referred to the Kingston council’s Integrated Storm Water Management Plan, but could not get a definitive answer.
Therefore, I decided to contact the council directly and speak to the relevant department. There I was informed that this requirement is typically tied to those constructions requiring planning permits i.e. multi-unit dwellings. Given that we were not in that category, then it was not necessary to install a tank.
Based on that information I informed Carlisle not to proceed with the tank installation. The price quoted was significant and it is something that we can easily look into in the future.
