Services

Calibrated Modelling:
AWT New Zealand can predict flow rates, surcharge levels and overflow frequency for any given rain event, identifying inflow and infiltration areas (I/I) and capacity issues. With this information AWT New Zealand offers different solutions for improvement. For complex projects, SEWCOM, a proprietary product, is used to run a large number of iterations to determine the optimum solution.

Environmental Flow and Quality Monitoring:
AWT New Zealand has extensive experience in monitoring and water quality testing and continually encourages employees to develop new techniques and services to increase the accuracy and reliability of monitoring data.AWT New Zealand's automated sampling system is capable of taking duplicate samples in both glass and polycarbonate bottles allowing a full range of contaminants to be analysed from a single event.

Flow Monitoring Services:
AWT New Zealand is the largest provider of flow monitoring in New Zealand, with up to 100 flow monitors installed in the field at any one time. AWT New Zealand supports and encourages its employees to continuously develop new techniques and services to improve the accuracy and reliability of flow monitoring data.

Overflow monitoring:
AWT New Zealand offers an economical and purpose-built system to provide sewer overflow monitoring, alarming and notification. The AWT Zealand system is a valuable tool for dealing with overflows - sending accurate information immediately to maintenance teams and decision makers. The system helps local authorities meet their environmental and regulatory obligations.

Sewer Rehabilitation:
AWT New Zealand has extensive experience with sewer rehabilitation projects throughout New Zealand, managing projects from $10,000 to $2 million. AWT New Zealand's engineering team provide expertise on sewer investigations and system review, data assessment and strategy development, through to managing the sewer rehabilitation works at the local level. AWT New Zealand’s OSH system has been recognised as best practice and ensures all projects are completed safely and without environmental incidents.

Typical Projects

AUCKLAND - installation of compound weirs providing flow data

WAIMAKARIRI - installation of 28 v-notch flow meters and 4 rain gauges for a period of 12 weeks

Project CARE:
Project CARE (Council Action in Respect for the Environment) is $280 million, 20-year project aimed at establishing and meeting the community and regulatory expectations for beach water quality.

The project was initiated by the North Shore City Council (NSCC) and AWT New Zealand was engaged to undertake a comprehensive study.

The study assessed the performance of the existing stormwater and wastewater systems to determine the impact on the water quality of the East Coast Beaches. AWT New Zealand then developed system management strategies to ease the impacts on local beaches of sewage overflow and urban runoff.

The overall project has been divided into four different phases:
-data collection
-model development calibration and validation
-strategy development
-detailed system improvement options

The investigation included building hydrological and hydraulic models to represent the wastewater and stormwater systems and a receiving waters model to simulate the impacts on the beaches. These models were later used to explore long-term options for improvement of the stormwater and wastewater systems of North Shore City Council.

The New Zealand Water and Wastewater Association granted AWT New Zealand an award for the conscientious effort in developing system improvement and management strategies to protect receiving waters and improve the amenities of the recreational areas.
