Rain works with developers of all sizes to deliver smart and practical solutions for urban stormwater management.
Proven Track Record
We specialise in designing major stormwater networks, including pipes, retarding basins, and water quality assets, ranging from small proprietary devices to major wetland systems. Our team understands the diverse planning and engineering requirements across councils and authorities and has a proven track record of helping projects meet regulatory standards without complications.
Best Practice Leaders
We keep up to date with the latest guidelines and are proud to be leading the way on best practice in Victoria. Rain is a contributor to the Victorian Urban Drainage Manual, which sets the standard for urban drainage into the future. This inclusion reflects our strong technical background and our reputation for providing clear advice while bringing a practical approach to problem-solving.
Better Development Solutions
