Our plans
as the city grows we create more barriers to
natural ground soakage. This increases the volume
of stormwater run-of, placing greater demand on
the city’s stormwater network.
In additon to growth, climate change means it
is raining more and standards are increasing to
protect our built environment from the efects of
climate change.
Our key challenge in the future is looking at the
best ways to integrate land use and the design
of stormwater assets. We want to make sure our
stormwater network is efcient, cost-efectve and
beter for the environment.

The stormwater network drains this run-of through
pipes and open watercourses into the city’s
streams, lakes and the Waikato River.
The Council manages stormwater through
encouraging ground soakage, providing a network
of pipes and open drains, landscaping, street
maintenance and planning controls.
Landowners are also required to allow as much
stormwater as possible to soak into the soil. This
replenishes precious groundwater reserves and
flters out many pollutants.
