Monitored sites in the Awapuni Drain catchment

No sites found.
The Awapuni Drain provides drainage from an area that prior to draining was a large wetland situated quite close to Gisborne City and stretching along the coast behind sand dunes to discharge into the Waipaoa River. The catchment area is small (14km2) but it captures a range of discharges from industrial sites.
Awapuni drain follows a path through land zoned industrial ‘B’ and discharges from a range of activities are monitored along the drain as part of resource consent conditions. Industrial activity includes: lamb processing, fertiliser mixing depots, a closed landfill (and associated aftercare programme, bark composting, a large wood processing plant and intensive horticulture.
The area that the Awapuni Drain flows through is very flat and not much above sea level in altitude. This makes the flow of water sluggish when freshwater needs to be drained from the vicinity. The flow is also tidal for most of the catchment and the drain has tidal flaps at the exit into the Waipaoa River. The tidal flaps restrict the ability of water to discharge into the Waipaoa.
A feature of the area is Sistersons Lagoon. This lagoon is fed by remnant springs and discharges into Awapuni drain. The lagoon is subject to successful community restoration work and hosts school groups regularly, providing educational opportunities.
Gisborne District Council has information from several sites on the Awapuni Drain. Most are associated with monitoring specific resource consents for discharges to land and water in the area.

The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for data collection, laboratory analysis of samples collected and the statistical analysis and interpretation of the results presented.
If all Cawthron ticks are green, then you can trust this data. However, if one or more ticks are orange, then conclusions should be treated with some caution.
For more details on each tick, see our 'Can I Trust This Data?' Factsheet.
All samples were collected using approved field protocols and have been analysed in accredited laboratories. Therefore the data shown here has been collected and analysed following best practice.

This data is not flow adjusted. National guidelines suggest that flow-sensitive variables are flow 'adjusted' before trend analysis. Therefore, any trends shown here may be affected by variations in flow across sampling occasions.
