for municipal and rural water supply.
Did you ever wonder why many rivers have
water in them when it hasn’t rained for days or
weeks, there’s no snow melting, and the
ground is dry? The rivers are being filled up by
water coming from out of the ground in the
form of springs and seepages which brings us
on to the topic of groundwater.
Groundwater facts
Groundwater is water which occurs in
formations below the earth’s surface. In
Taranaki we use 44,022m3 per day but

current consent. The site has not been used in recent years.
The discharge site is approximately 120 m long and 25 m wide, and is shown in Figure 2.
Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on the site drains away
at a very rapid rate. The site does not suffer from flooding from rain or tidal action, due to its elevation.
1 The Council has used these compliance grading
typical example.
Water Rain: - raindrops falling on bare earth wash the soil away. The rain soaks into
the soil making it heavier and causing it to sometimes slip away.
Sea: -waves crash against the coast, grinding rocks into sand and cutting back
the edge of the coast. Coastal drift carries the sand along the coast to calmer
water where it builds beaches.
Rivers: - the force of the flow cuts away at the banks of the river causing them
to become undercut and fall

1.4.4 Chemical sampling
Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on
the site drains away at a very rapid rate. The site does not suffer from flooding from
rain or tidal action, due to its elevation. Monitoring over the past three years noted no
discharge of leachate or liquids from the base of the dune as a result of the discharge.
Therefore, no water quality samples were programmed or collected at the site

It is acknowledged that other site-specific
considerations will also have to apply, such as:
1. the avoidance of conflict between air discharge
points and neighbouring dwellings
2. land contours
3. orientation to the sun.
(f) Discharge point design
Dispersion of discharges is enhanced by:-
increasing the height of discharge points;
avoiding the use of conical rain shields over
discharge stacks;
There were plenty of April showers last month with nearly 775mm of rain at the North Egmont Visitors Centre and 574.5mm at Dawson Falls. Rainfall was on average 101.8% of the long-term average, and ranged from 65% at Taungatara at Eltham Rd and Oeo u/s Awatuna Wetland, to 192% at Matarawa at Matarawa Valley. Year to date rainfall is sitting between 103% (Mangati at SH3) and 206% (Matarawa at Matarawa Valley) with an average of 139.7% of normal. Mean river flows were 133.8% of typical values,
as well as ensuring public awareness of the impacts of
stormwater on recreational water quality particularly after a rain event. In the coastal water, where most
people are likely to bathe, counts were well within ‘Surveillance’ mode (MfE, 2003; Table 3). The health risk
overall, was therefore considered to be low.
The addition of groundwater monitoring to the 2023/24 programme allows the Council to track impacts to
groundwater quality from the WWTP. In the first year, groundwater samples

all this autumn colour means a lot of leaf fall and subsequent raking. To be honest, we sometimes run out of places to hide them. Thankfully, the idea of removing every leaf is fading away. The benefits of leaf litter, the fungi that consume it and recycling it into the soil are now being recognised. Our current process is to clear paths, chop up anything that falls on the grass and add it back to the turf. The general policy is to leave what we can to be broken down and added to the soil
