Environment
Minimising the impact of the college's drainage solutions on the environment
Drainage Systems
Development increases the area of impermeable surfaces increasing runoff capacity; which can increase flood risk. In order to avoid this risk, natural site water cycles should be reinforced. Where possible infiltration drainage should be used. For example, swales and grasscrete.
Questions to consider
- What is the drainage layout for the proposed college?
- Does the drainage system incorporate sustainable drainage (SUDS) principles?
At what design stage should this issue be considered?
DESIGN
Discharges to surface/groundwater
The proposed college will have associated discharges to surface and or groundwater. These discharges may be wastewater from sanitation, cooking or waste water. Discharges to surface and groundwater should not lower the quality of the receiving water. To ensure that the integrity of the water resource is maintained monitoring of discharge maybe required.
Questions to consider
- What are the water quality targets for the project?
- Are they stricter than local water quality regulations?
- How clean is the water that leaves site?
At what design stage should this issue be considered?
DESIGN
Sewage treatment
Utilisation of on-site organic process treatment facilities has the least impact on the environment but requires a certain amount of external ground area to accommodate it. In a college a facility such as this could be a useful education tool and nature reserve.
