Accurate surveying for drainage planning, compliance and site design.
MCS Surveyors provide precise and comprehensive stormwater drainage surveys for residential, commercial and civil projects across Sydney. Whether you are submitting a development application, designing stormwater systems, or managing drainage upgrades, our surveys deliver the essential data needed for informed planning and regulatory compliance.
Stormwater drainage is a critical aspect of site design, directly affecting flood risk, erosion, water quality and the structural integrity of surrounding infrastructure. Our experienced surveyors support architects, engineers, builders and developers by delivering accurate site assessments that identify drainage paths, levels and connections for both pre-existing and proposed conditions.
A stormwater drainage survey maps the existing and proposed stormwater infrastructure on or around a site. These surveys provide detailed information about surface runoff, existing drainage points, service connections and terrain grades.
Depending on the project requirements, stormwater drainage surveys may include:
Stormwater surveys are typically conducted during the planning or civil design phase and are used by hydraulic engineers and planners to ensure that the proposed development meets council and environmental standards.
Stormwater management is not just a design consideration, it is a legal and environmental requirement for most developments. Poorly designed or inadequately assessed drainage systems can result in:
A professional stormwater drainage survey helps avoid these risks by giving engineers the accurate, site-specific data they need to design compliant and functional drainage systems.
MCS Surveyors delivers high-accuracy stormwater surveys tailored to your project scope. Our services support residential lots, multi-unit developments, subdivisions, civil works and infrastructure projects.
We survey all visible and accessible drainage assets on the site and in the immediate surrounds. This includes:
We also identify outfall connections and any easements or service corridors relevant to drainage.
Our surveys include detailed ground level data to support drainage design and runoff analysis. Deliverables can include:
This data is particularly important for determining site falls, drainage direction and cut-and-fill requirements.
We provide as-built drainage surveys following the installation of stormwater infrastructure. These are used to:
Our as-constructed surveys include detailed plans showing the final position, level and specifications of installed drainage structures.
For larger developments, our drainage surveys can be used to support the design of OSD systems or water-sensitive urban design (WSUD) features. We work alongside your hydraulic engineer or consultant to deliver coordinated survey data suitable for detention tank design, discharge control structures or infiltration areas.
Our stormwater drainage surveys are used across a wide range of projects, including:
No matter the scale or complexity of your project, MCS Surveyors provides clear, accurate and timely data to keep your project compliant and on track.
With over 30 years of combined experience, MCS Surveyors is a trusted name in civil and construction surveying across Sydney and NSW. We understand how critical drainage is to site design, stormwater compliance and project approval.
What sets us apart:
We work closely with hydraulic engineers, certifiers, local councils and builders to ensure drainage designs are based on trustworthy data.
