Treatment elements (or ABC Waters design features) can be applied to urban components to slow down, detain or retain the first flush of stormwater runoff while simultaneously cleansing it.
They are cost-effective, natural and environment-friendly green features for sustainable stormwater management. The cost is a small percentage of the total capital cost of the development, while the resulting environmental benefits are many.
As ABC Waters design features are natural systems of plants and soil, minimal maintenance is required.
Please refer to “Engineering Procedures for ABC Waters Design Features” for generic maintenance requirements. The document also gives guidance on selection and sizing of the treatment elements with worked examples and checklists.
