Accreditation regarding Rainwater Harvesting Systems
Permissions for installing rainwater harvesting systems can vary from state to state and will depend on what the policy of legislators is. Some states have a proactive attitude to rainwater harvesting and allow residents to utilise this efficiency method. Others have concerns about preserving water supplies for agricultural land, especially in drought regions and people can even be prosecuted for installing such as system.
There is no strict accreditation system for installers but you should make sure that your chosen company has the right building qualifications for installing tanks and storage.
