The current waste water treatment system is inadequate and unable to deal with combined household and surface water discharges at the present time. This is only going to be exacerbated by the proposed level of development, particularly in an area with high groundwater infiltration levels.
A reduction in the housing allocation numbers to a much more sustainable level
The current waste water treatment system is inadequate and unable to deal with combined household and surface water discharges at the present time. This is only going to be exacerbated by the proposed level of development, particularly in an area with high groundwater infiltration levels.
In 2022, the storm discharges from waste water treatment works into Chichester Harbour totalled:
Chichester (Apuldram) – 87.33 hours (3.64 days)
Bosham – 791.54 hours (32.98 days)
Thornham – 585.02 hours (24.38 days)
In addition, data has also been supplied since 2020 for 5 CSO’s that discharge into the Harbour. The most significant of these in 2022 was Priors Leaze, Nutbourne, which discharged for a total of 8.03 days. It should be noted that the harbour also receives storm discharges via Budds Farm in Langstone and the Lavant WWTW.
It is very hard to foresee how Southern Water, given the current regulatory framework, will be in a position to provide the necessary infrastructure to accommodate the development levels proposed. Recent permitted developments in the district rely on removal of waste by tanker, to avoid back-flowing sewage.
Likewise in a region of water scarcity, which will only worsen in the future with climate change, the proposed level of development is utterly unsustainable. The water-recycling proposals at the Havant Thicket reservoir site are deeply unpopular with the local community.
