Requirements for Towers
Guide to Cooling Towers
Our guide will show you how to design for and convert to recycled water at your worksite. Whether you’re constructing a new facility or re-plumbing to change the water source for your cooling system, there are a few state and local requirements you’ll be asked to meet. These are basic regulations from the State Water Resources Control Board - Division of Drinking Water (SWRCB - Division of Drinking Water), SBWR and the Uniform Plumbing Code.

Most requirements can be satisfied with a thoughtful design process. And, because a permit issued by SBWR covers all SWRCB - Division of Drinking Water conditions for using recycled water, you won’t have to negotiate individual use requirements with state agencies.

Get Started
To begin the process, you’ll explain the details of your project to SWRCB - Division of Drinking Water and SBWR through an Engineering Report, which can be generated using our Engineering Report template. The report will also cover your design plan for protecting the public water supply – this can be as simple as identifying recycled water pipes with purple tape, tagging valves and having an air gap that feeds water into the tank.

The recycled water regulations are in Title 22 of the California Code of Regulations, the California Plumbing Code, and the South Bay Water Recycling Rules and Regulations. Use the design tools to assist in preparing your required plans and reports. View a diagram guide to the requirements for designing a cooling tower for recycled water.
