Research State and City Regulations.
Before you begin installing your sprinkler system, it's important to research the regulations in your state and city. Make sure your contractor is a Licensed Irrigator and is Registered with the City of San Antonio as an approved contractor in good standing. Each state and city may have different requirements for sprinkler system installation, such as the type of backflow prevention device required or the distance between sprinkler heads. You can typically find this information on your state or city's government website or by contacting your local water department. It's important to follow these regulations to ensure your sprinkler system is installed safely 
and legally.

Obtain Necessary Permits.
Once you have researched the regulations in your state and city, you may need to obtain permits before you can begin installing your sprinkler system. The requirements for permits may vary depending on your location and the scope of your project. Some cities may require a permit for any type of sprinkler system installation, while others may only require a permit for larger projects. It's important to check with your local government to determine if you need a permit and what the process is for obtaining one. Failure to obtain necessary permits can result in fines or other penalties.

Choose the Right Sprinkler System.
Before you can install a sprinkler system, you need to choose the right one for your needs. There are many different types of sprinkler systems available, including rotary, spray, and drip systems. Each type has its own advantages and disadvantages, so it's important to do your research and choose the one that will work best for your lawn and garden. Consider factors such as the size and shape of your lawn, the type of soil you have, and the plants you want to water. You may also want to consult with a
professional landscape irrigation specialist to help you make the right choice.

Plan Your System Layout.
Once you have chosen the right sprinkler system for your needs, it's time to plan the layout of your system. This involves mapping out where each sprinkler head will be placed and determining the best locations for the control valves and water source. It's important to consider factors such as the slope of your lawn, the location of any obstacles such as trees or buildings, and the water pressure and flow rate of your water source. You may want to use a professional irrigation designer or contractor to help you with this step to ensure that your system is designed for maximum efficiency and effectiveness.
