hi guys, my property is 152 on the attached map.. im curious as to what the indicators i have highlighted in yellow on my plan for my property are. i know the one in red is sewerage. im hoping the yellow is for storm water as the property is on a slant away from the street & i intend on building a duplex on the block & if this is storm water it would simplify the process greatly.. cant find anything about it on the contract, DBYD or sydney water Tap in i know a property on the same slant as myne 5 doors down only had to attach to existing storm water services..
