Optimal Stormwater wins City of Sydney Stormwater Harvesting Operation and Maintenance of 20 sites

Optimal Stormwater has recently won the contract for the Operation and Mainteance of 20 of the City of Sydney’s stormwater harvesting systems.

Operation and maintenance has already commenced and the stormwater harvesting optimisation plan has a system which automatically uploads performance data on each of the 20 sites to the City of Sydney internal website server.

The City of Sydney selected Optimal Stormwater based on the strength and knowledge of the team and the optimisation plan was well ahead of other tenderers including Neverstop, Veolia and Sydney Water.

The servicing contract is for a period of 3-5 years and will include existing major facilities such as Sydney Park, as well as new systems for Green Square and Harold Park when they come online.  Optimal Stormwater has constructed two of the systems – Alexandria Oval and Waterloo Oval and has already commenced rectification works on a few of the plants as part of the optimisation plan.

Bankstown Council, Optimal Stormwater & Bell Environmental win 2015 Stormwater NSW Award of Excellence in Asset Management

Optimal Stormwater won our 3rd award at the WSUD 2015 Stormwater Industry Association NSW Annual Awards night for Excellence in Asset Management.

Bankstown City Council has been awarded the Stormwater NSW Award for Excellence in Asset Management collaborative work with Optimal Stormwater and Bell Environmental.

Optimal Stormwater undertook a comprehensive GPT audit and provided detailed cleaning information to Bankstown Council for their next cleaning tender. By providing detailed critical information about all the GPTs such as pollution volume, cleaning frequency, de-watering locations, traffic management details, access keys, machinery required; cleaning companies no longer have to guess about items or inflate prices for contingencies. As a result, Council received the most fair and comprehensive GPT tender and received the best prices they have ever received for the cleaning of their GPTs.

Hume Council, Optimal Stormwater and Stormy Water Solutions win 2015 Stormwater Victoria Award of Excellence in Asset Management

Optimal Stormwater won another industry award at the 2015  Stormwater Industry Association for Victoria. Optimal Stormwater submitted for Excellence in Asset Management with Hume City Council for Excellence in Asset Management based on  collaborative effort with  Optimal Stormwater and Stormy Water Solutions. 

Optimal Stormwater undertook a comprehensive WSUD audit for Hume Council followed by Council GPTs.  This provided a clear picture on how their stormwater treatment assets were performing.  Some excellent outcomes included identifying cost effective upgrade of existing assets, as well as some that just needed maintenance.

Another positive outcomes was the capacity building and ownership of the ongoing maintenance that resulted.  Works on the ground have commenced with WSUD rectification designs by Optimal Stormwater and construction completed by Indigenous Design contributing to the success story.

Optimal Stormwater wins the City of Sydney MUSIC Modelling

Optimal Stormwater has won the updating of the City of Sydney MUSIC modelling.

The project is to update the City of Sydney’s existing catchment MUSIC models with the WSUD initiatives that have been implemented since the original Decentralised Water Master Plan. The project analyses, refines and updates all existing MUSIC models for all WSUD developments, GPTs, Public Open Space WSUD developments and roads and streetscape WSUD developments. The project involves analysis of all existing GIS, WSUD, stormwater

Optimal Stormwater wins the design and construction of a CDS1009 Unit for Lane Cove Council

Optimal Stormwater won the design and construction of a CDS P1009 unit at Lane Cove West for Lane Cove Council.

The GPT is to treat the catchment discharging into the newly constructed Blackman Park Creek and WSUD system. The CDS 1009 will also involve improved drainage hydraulics and creek rockwork.

This is the third GPT Optimal Stormwater has designed and constructed for Lane Cove Council and we are very pleased to continue the relationship of protecting the

Optimal Stormwater finalises stormwater harvesting design and construction for Kogarah Council

Optimal Stormwater won the design and construction of a reasonably small harvesting system for the Kogarah Council depot at Carlton.

A previous harvesting system was in place on a Sydney Water channel nearby, and Optimal Stormwater was selected to upgrade the offtake works, plan a new rising main to get this water to the Council depot, install a new treatment and disinfection system, and store the water in new elevated polymer tanks.

The harvested water is used for high pressure washing of garbage trucks and fill tankers for remote irrigation of median strips, parks and gardens. It was designed and constructed to allow for a recycled water extension to the nearby sportsfield for Council to consider as a future project.

The water was desired to have a 0.5mg/L chlorine residual, so a sodium hypochlorite dosing system was used for the disinfection. This is Optimal Stormwater’s first chlorine stormwater treatment plant so we now have designed and constructed every kind of stormwater treatment system possible and are able to choose between multiple types of stormwater treatment systems for future projects.

Optimal Stormwater undertakes the construction of a new stormwater harvesting pumpwell for a CDS 2028 Unit at Clovelly Beach

Optimal Stormwater was engaged to undertake the construction of a stormwater harvesting pumpwell connected to a CDS 2028 Unit at Clovelly Beach for Randwick Council through KK Civil.

The existing pumpwell and stormwater harvesting configuration was incorrectly designed or installed and Optimal Stormwater have been engaged to construct the new pumpwell and stormwater harvesting connection works, along with CDS lid strengthening and CDS diversion chamber vent to allow for the effects of high tide, strong waves and storm events.
