Welcome to the Bunnings Workshop community @Shahid_mel. It's fabulous to have you join us and many thanks for your questions.
You might need to provide some more information about why you are installing the drainage, where it is to be installed and what type of drainage you intend to use for our members to offer assistance. Some photos of the area and of the stormwater access point would also be beneficial. If there are any particular questions on the installation process you had I trust our helpful members will be able to answer them for you.
