Martyn Cole Water & Wastewater Asset Manager Kapiti District Council Tracy Clode Associate – Project Management CH2M Beca Introduction Monitoring Data Management Reporting Adaptive Management Group Changes to Consents Into the Future Introduction September 2013: 35 year consent granted (78 pages of conditions) Innovation . Ground water discharge to river so more river water could go to supply . No NZ precedent . Tests and trails conducted during consenting Monitoring . Conservative approach as implemented full scale . Extensive monitoring regime . 3 year baseline monitoring Adaptive Management . Ongoing compliance review . modification of monitoring and operation

Monitoring

Small Coastal Streams Borefield Water Conservation Automated data collection (136 parameters) 7 Small Coastal Stream site . Each with in stream DO, Temperature, and water level. Plus piezometer ground water level. 13 Wetland sites . Each with a piezometer ground water level. Some sites have more than one piezometer. Borefield sites . 13 Electrical conductivity sensors . 32 Piezometer ground water level sensors across deep and shallow aquifer River and WTP sites . Water level in river . 2 Raingauges . 8 Production bores data collection including instantaneous pump rates and daily abstraction rates . 3 flow meters through the WTP Manual Data collection (1400+ parameters) . 320 Production Bore Water quality sample parameters (monthly) . 520 Wetland condition monitoring parameters across 13 sites, plus aerial photos + photo points . 180 at 5 River Condition monitoring parameters across 5 locations (every 2 weeks or more in summer) . 378 Small Coastal Stream parameters across 7 sites (monthly) . 6 parameters across 2 River flow gauging sites . 7 Small Stream Fish Surveys . 5 River Fish Surveys . 2 Upstream Tributary Fish Surveys . Additional Borefield water depth and EC measurements as needed. . Additional monitoring as and when needed should trigger levels activate.

Review Conclusion

Innovative scheme required a conservative approach

The collaborative and pragmatic approach has resulted in an efficient and effective monitoring regime

Adaptive management approach is working Questions
