Stormwater Drainage & Hydraulic Designs
When building a new home, it is important to ensure any future rain water is collected from the roof, driveway and footpaths and is properly managed to avoid excess water runoff onto council and/or neighboring properties. Vacant land in new subdivisions doesn’t generally require a hydraulic design to be completed by an engineer, because the developer provides the necessary provisions and infrastructure to drain the right amount of water for future development in the area. For vacant land, we submit a concept stormwater design (which forms part of our drawings) to council or the certifier for approval. For knock down rebuilds in existing suburbs, especially in older areas, the stormwater infrastructure often isn’t adequate to carry the amount of water runoff from new homes that are typically bigger than they used to be. Because of this, councils have put policies in place to
ensure the stormwater runoff on new or re-built homes will not overload the current infrastructure in the area. This is when a qualified hydraulic engineer is required to design a system that will satisfy council - a requirement for the home to be approved. Even when lodging a Complying Development Certificate (CDC) application, councils policies around stormwater disposal are still necessary. Depending on the council and the approval, certification of the design and work (including the ‘work as executed’ survey) may be required to show council it has been built to the appropriate design. If a professional hydraulic design is required for your approval, we will include the cost of the design in the tender document. We will also provide a provisional allowance to cater for the costs of work related to the design, which can’t be determined until the design is complete.
