To control sediment discharges, our goals are:

1.1 Ensure the quality of stormwater from all new development sites or re-development sites is treated to best practice.

1.2 Stormwater treatment facilities are constructed according to best practice.

1.3 Sediment from 95% of consented construction activities on the flat is treated to best practice by 2025.

1.4 Analyse options for carrying out street sweeping, sump cleaning, and diversion to wastewater trials in 2020/21 (Schedule 4b and d).

Recommended for further consideration

1.5 Road sediment is reduced by a best practicable option determined by the results of street sweeping, sump cleaning and alternative treatment trials (Schedule 4c, f, g and h).
