shows that groundwater levels are generally stable, with fluctuations the result of seasonal rainfall and pumping effects. It was noted that we are already starting to see an increase in demand for ground water and this has the potential to grow in response to pressure on surface water. However, it is not expected that this will place groundwater under significant pressure in the near future. Also, groundwater Policy and Planning Committee - Confirmation of Minutes 7 page

community conversation about the best approach. This is a major issue on the road ahead as climate change is expected to have wide-ranging impacts on our region. The temperature is expected to increase by between 0.5°C and 1.5°C by 2040, while rainfall will become more variable, increasing the risk of drought on one hand and the risk of floods on the other. Rising sea levels will increasingly threaten coastal communities and these changes will put more stress on already struggling
Waiwhakaiho and Bell Block and as such signage remains in place at these locations to advise against collecting shellfish. There were eight unauthorised incidents that occurred at the NPWWTP during the year; three due to blockages, two due to heavy rainfall, and three due to operator errors. Four events were recorded for sewer pump stations (all due to high rainfall), and a further 15 reticulation overflows (the majority of which were due to high rainfall or blockages due to fat and/or wet

that so few limits were breached indicates excellent management of the scheme. There are certain operational requirements also set by consents, which require flushing flows of 400L/s to be released down the residual flow reach once the Tariki weir has not naturally overtopped for 30 days. There was one occasion during April 2024 when the Company provided a notification with regard to extremely low flows in the Manganui River due to unusually low rainfall for a sustained period.

water allocation across Taranaki and details the technical work done to help support the implementation of the NPS-FM requirements. Overview of surface water quantity Taranaki receives frequent and plentiful rainfall. The amount of rainfall is extremely variable however, increases significantly from the region’s coastal fringes to areas of higher elevation across the eastern hill country and the slopes of Taranaki Maunga. Much of this rainfall rapidly flows to the sea via rivers
by NPDC assessed for compliance upon receipt. The monitoring showed that the activities were generally being carried out in compliance with the conditions of the resource consent. The results of surface and groundwater quality monitoring undertaken show no adverse effects of the activity on local fresh water resources. Site visits undertaken found the site to be tidy and well managed. During this monitor year, following higher than average rainfall the minimum separation distance
collection and retention systems; stormwater sampling and inspections of the discharge point and receiving waters in the Herekawe Stream. Scheduled inspections were carried out on 6 July 2023 and 3 August 2023. Notes from these visits are summarised below. 6 July 2023 First inspection for 2023/24. On site 14:00 to 14:50 representatives from Dow, Tonkin & Taylor and SGS. 50mm of rainfall had been recorded over the previous week at the Brooklands Zoo station. Stormwater ponds SV8000 and SV9200
