Purpose
1. Jim
Jackson from The Manukau Harbour Restoration Society Inc requested an
opportunity to speak on the following:
i) Hydrodynamic Modelling of the Manukau Harbour
update.
ii) Raw sewer discharges into the Manukau Harbour during
storm events and its impact on short term and long term water quality.
iii) Auckland councils stormwater separation at source
policy.
iv) Responsibility of Watercare and Healthy Waters to
manage and provide a more reliable system to avoid stormwater ingress into
Watercare’s Sewer Network.
v) The ongoing relevance of consent to conditions
in favour of Watercare to discharge raw sewage into the Manukau Harbour
during equipment failures and storm events.
vi) By Passes from the Mangere Waste Water Treatment
plant into the Manukau Harbour during storm events.
vii) Stormwater flow has a negative impact on the
operational requirements of the MWTP.
· During normal operations the MWTP plants performs
exceptionally well however during storm events its performance is highly
compromised and can take many days to return to normal operation.
viii) When By Passes occur at the MWTP the Manukau
Harbour it is during these periods that the harbour is being used to treat
waste water and does Watercare have consent to use the harbour for treatment
purposes?
· Negative impact on saltwater marine life with the
large quantities of treated waste water (fresh water) being discharged into
a shallow upper harbour location with limited flushing every 24 hours
which takes 12 days to reach the Tasman Sea.
ix) Councils Safe Swim beach water quality ratings
program of beaches around the Manukau Harbour especially Long Term
Water Quality Alerts.
· Taumanu East
· Clarks Beach
· Laingholm
· Huia etc.
· Septic Tank Leakage
· Overflows from waste water pipes.
· Does Council have a long term plan to address this
problem
x) The importance of establishing locations around the
harbour to collect robust and reliable water quality data.
xi) Implementing plans to deliver a reduction in
phosphorus and nitrogen levels in to the Manukau Harbour
xii) Consent hearing regarding the proposed Clarks Beach
new Waste Water Treatment Plant
xiii) The cancelation of the EWL and the short and long
term implications to upper Manukau Harbour redevelopment options
xiv) Ownership of the Port of Onehunga
xv) Redevelopment of the Port of Onehunga
xvi) POAL NZTA’s & Panuku’s short
and long term plans for the redevelopment of the Port of Onehunga
xvii) Dredging at the Port of Onehunga.
xviii) Dredging at the Waiuku Wharf.
xix) What is to be done with the dredged sediment?
xx) Replacement of the Mangere Onehunga Pedestrian
Bridge including
xxi) Light Rail station at Port of Onehunga
xxii) Floating temporary dock at Port of Onehunga
xxiii) Ferry service on the Manukau Harbour
xxiv) Identifying and delivery of core Manukau Harbour
Infrastructure
xxv) Mooring locations around the harbour to be sited in
protected locations wind & tidal movement.
xxvi) Greater presence of Fisheries Officers to ensure
abuse of the catch limits are complied with.
xxvii) Should the business model to manage the Manukau
Harbour be revisited maybe along the lines of the following:-?
· Manukau Harbour Authority (MHA) be established that
has the operational requirements of an Urban Development Authority (UDA).
· The MHA to be made up of the Crown, Auckland,
Council, Iwi & Key Stakeholders
· The MHA has a robust funding stream.
· The MHA makes decisions not recommendations.
· The MHA has a chairman to lead the process who has
strong business environmental management and local knowledge skill set.
xxviii) The long term goal of MHF should be to set a time
line to improve significantly harbour fish stocks followed by a goal that we
can gather shellfish and eat them safely, catch fish and eat them
safely and swim anywhere in the harbour safely.
· These are simply objectives but generationally will
be the key to improving this harbour that has been abused for the past 100
years.
