Why is the project relevant to you?

When planning local developments, it's increasingly important to consider water resource impacts. Water companies are not required to provide water for commercial purposes. Planners need to consult with water companies to meet water demands for new non-domestic properties. Including rainwater harvesting in building designs can help meet non-drinkable water needs and is viewed positively by water companies.
