Te Whariki - Stormwater Management in a Residential Development
Stormwater Conference
❄
Te Whariki is a joint venture Ngai Tahu Property and Lincoln University residential development in Lincoln, Canterbury. This transition of a greenfield site into extensive urban development includes the use of constructed wetlands which have shown improving stormwater treatment efficiencies.
The site receives stormwater from the Lincoln urban area as well as on-site runoff, and discharges into the spring-fed LII River. Water quality monitoring is undertaken to determine if contaminant sources are on-site or off-site, and to manage those sources. The consent conditions have at times proven challenging to monitor; with tight monitoring schedules, and the development’s progression affecting the location of monitoring sites.
Through involvement from the early stages of earthworks, to the near fully built Ivey neighbourhood, I have observed and will discuss the variations in water quality and the practicality of monitoring conditions.
