Hunua 4 Watermain

Hunua 4 Watermain

The Hunua project is the biggest water pipeline project undertaken in New Zealand for many years and involves 30 kilometres of 1.3 to 1.9 metre diameter steel pipeline traversing Manukau and Auckland cities. It involves the crossing of Manukau Harbour, three motorways, three railway lines, a creek and eight streams.

GHD was engaged in 2005 to carry out an options study for a new watermain from 'southern sources' to 'city centre'.  As a result of a competitive tender, GHD was jointly awarded the design contract in strategic partnership with engineering consultancy CH2M Beca in 2008.

Hamilton Water Treatment Plant

image

The Hamilton City Council in New Zealand wanted a world-class Water Treatment Station that met the city's water needs and exceeded or met New Zealand Drinking Water Standards at the lowest whole-of-life cost.

The original Hamilton Water Treatment Station (WTS) was a conventional clarification and filtration plant with a nominal capacity of 80 ML/d. The WTS drew water from the Waikato River and, in recent years, the water has shown increasing levels of unpleasant taste and odour as river algal levels increased. Cyanotoxins levels above detectable levels have also been found.

Christchurch Earthquake Emergency Response and Infrastructure Recovery

Support from the GHD team across New Zealand aided the quick deployment of specialist personnel and equipment to Christchurch.

The Christchurch earthquakes caused damage to almost half of the city’s urban roads. Almost 900km of Christchurch’s road network suffered damage necessitating not just repair, but rebuilding. The immediate challenge for GHD, however, lay in repairing and rebuilding key strategic road links for emergency response vehicles and vehicles delivering life-dependent supplies such as clean drinking water.

Non-revenue Water (NRW) Management Review

Non-revenue Water (NRW) Management Review

GHD was appointed to undertake a peer review of the program to determine if the current activities will reverse the rapid rise in the level of Non-revenue Water (unaccounted-for-water) and to identify what was required to achieve Metrowater’s (New Zealand) NRW targets.

The review process was guided by an overall audit process, data pathway analysis that examined the data from its capture through to its application in forecasting future NRW levels. The analysis of migratory nature of losses within the equilibrium equation of the water balance requires identified the cause and effect of the various errors associated with measuring and/or determining the different volumetric components. This process facilitated the determination and quantification of the various components of real and apparent losses..

Clear Harbour Alliance

Christchurch wastewater overflows – consent application

With the growth of Auckland City, the combined stormwater/wastewater system was exceeding capacity during rainfall events, resulting in pollution of the Waitemata Harbour. A conventional project model could not guarantee the level of service that Metrowater wanted for their customers during the separation process so they decided on an Alliance model – one that was strongly customer focussed. The project goal of cleaning up Auckland’s harbour was a philosophy of shared ownership and responsibility reflected in the principle – "it's ours".

Metrowater is Auckland City's water and wastewater utility and was established by Auckland City Council to provide water and wastewater services to over 142,000 homes and businesses, reaching 420,000 people across Auckland City. The area of operation covers 153 square kilometres with a water and wastewater network of more than 3,600 km of pipes. Metrowater’s expectation is that their customers receive the highest quality, reliable water supply possible and that Auckland City’s wastewater networks are managed in a cost effective, environmentally sound and sustainable manner.

Managing stormwater is one of Auckland City's many activities. Auckland City aims to protect Auckland's unique and valued environment and allow for future urban growth. It is Auckland City's job to assist Auckland's residents to make sure stormwater is managed properly on their land, and to safely remove stormwater across the city.

Auckland Transport’s drainage assets consist of approximately 27,500 catchpits, 2,300 soakholes and 550 manholes within Auckland’s central city and the Hauraki Gulf islands.  The condition and performance of these structures is critical not only to the city’s wider drainage and reticulation system, but also to the efficiency, safety and reliability of the transportation network.

Christchurch wastewater overflows – consent application

Christchurch wastewater overflows – consent application

Rebuilding Christchurch’s infrastructure is one of the largest and most complex civil engineering projects ever undertaken in New Zealand. The infrastructure rebuild project will be on-going for at another least five years and is expected to cost approximately $2.5 billion.

In October 2011, GHD was engaged by Christchurch City Council to prepare and submit a regional consent application to repair and upgrade Christchurch’s earthquake damaged wastewater infrastructure. Even though the repairs were essential for the long-term social and economic success of Christchurch, it was anticipated that the works could result in the discharge of untreated wastewater into the Avon and Heathcote Rivers, and the Avon-Heathcote Estuary. It was therefore paramount that any discharges were mitigated and/or avoided where possible, so that public health and safety was maintained.

Ammonia Phosphorus Removal, Metropolitan Syracuse Treatment Plant Onondaga County (NY, USA)

In partnership with two other firms GHD was retained by Onondaga County, New York to provide engineering services in connection with the design and construction of improvements to its 84 million-gallon-per day Metropolitan (METRO) wastewater treatment plant, with the objective of upgrading the level of wastewater treatment provided for ammonia and phosphorus removal.

The project established that the facility, which provided conventional secondary treatment (with seasonal nitrification and phosphorus removal to less than 1.0 mg/L), needed to be upgraded to provide year-round ammonia removal (1.0 mg/L as N for June 1st to October 31st, and 2.0 mg/L for November 1st to May 31st), and phosphorus removal to 0.12 mg/L TP for a 12-month rolling average.

Santa Rosa Urban Reuse

image

The City of Santa Rosa’s water recycling program provides high-quality water for agriculture, energy production and urban uses. Historically, this program was managed for its wastewater disposal benefit.  GHD assisted in the development of the City’s Incremental Recycled Water Program – a 30 year master plan for managing the system. We then led a consulting team tasked with evaluating a range of alternatives for expanding Santa Rosa’s urban water recycling program by up to 6600 acre-feet per year, as one piece of the incremental program.

Because of an increasingly constrained regional water supply, the benefits of urban reuse were studied by the water utility and wastewater utility in partnership. The analysis included over a dozen alternatives for system configuration and size and concluded that a 3000 acre-foot expansion provided the best value for both utilities.

91st Ave Treatment Plant

The 91st Avenue WWTP Chlorination Improvements project involved the replacement of a 120-ton bulk chlorine system with a system consisting of 32 one-ton chlorine cylinders.  The plant has a treatment capacity exceeding 180 mgd. The existing chlorination equipment and piping was replaced while the plant was in full and normal operating condition. The plant’s treated effluent is used at the Tres Rios Wetlands and as cooling water for the Palo Verde Nuclear Generating Station.

The project also involved the development and coordination of the Maintenance of Plant Operation (MOPO) procedures. The chlorination of the plant effluent had to be maintained at all times during construction. The project also included building structural, electrical, and HVAC modifications. The equipment installed included the following:

Cox Creek Wastewater Treatment Upgrade (Md, USA)

GHD was retained by Anne Arundel County for the Enhanced Nutrient Removal (ENR) Upgrade of the Cox Creek Water Reclamation Facility (WRF). The 15.0 mgd (56.7 ML/d) Cox Creek WRF is the largest of the County’s seven (7) major wastewater treatment facilities and is also the County’s largest single contributor of nitrogen and phosphorus to the Chesapeake Bay. 

During the facilities planning phase, a comprehensive examination was made of all plant unit processes and hydraulics.  As part of this project, a decision was made to expand the peak day hydraulic capacity of the facility from 30 to 45 mgd (113 to 170 ML/d) to accommodate observed I/I derived peak flows. ENR alternatives were evaluated in a two-step approach with the first step shortlisting to three alternatives and the second step selecting the final recommendation based on conceptual designs and lifecycle cost analysis. A Membrane Bioreactor (MBR) process was selected to replace the existing MLE process. MBRs proved to be the right choice for the Cox Creek WRF due to very tight site constraints, inadequate existing reactor volume to fully nitrify year-round, inadequate existing secondary clarification facilities, limited hydraulic head available for process modifications, and the County’s desire to produce as high of quality of effluent as possible with the maximum degree of reliability.
