TURNING A SPILL INTO A RECYCLING OPPORTUNITY FOR DM ROADS

CLIENT: DM Roads
INDUSTRY: Roads
TYPE OF PROJECT: Recovering Truck rollover Spill from waterway.
WHEN: April, 2020

BRIEF:

On the afternoon of Wednesday April 8 road network management leader DM Roads sought the assistance of Pipe Management Australia following a truck roll over on the Great Western Highway at Pendle Hill in Western Sydney. The accident led to 30,000 litres of silica grout liquid spilling into the stormwater causeway and entering into the main drainage system and into the waterway.

CHALLENGES:

The urgency of this job demanded an immediate and coordinated response that would require a multi-vehicle fleet and a large team. The work involved operating near a busy arterial road during peak evening traffic, and time was of the essence in order to ensure all contaminated liquid could be contained and removed from the waterway.

PMA SOLUTION: 

Through our emergency response team, the PMA crew and Combo Drain Cleaning units were on the road within an hour and headed for the spill site from the company’s NSW headquarters in Ingleburn. Over the next 48 hours, four PMA trucks and up to eight PMA staff worked round the clock to remove the large volume of waste liquid that had entered the drainage system before it moved into the waterway.

Using its fleet of purpose-built, state of the art large combination drain cleaning and recycling units, PMA removed all the stormwater containing the potentially dangerous silica grout liquid from the waterway.

As a leading utilities management service provider serving the east coast of Australia, PMA looked beyond simply solving the problem at hand for DM Roads. The management team looked at where they could provide proactive, additional value to the client and investigated the possibility of recycling the spilled product with the assistance of Bulk Recovery Solutions, one of PMA’s waste facility partners.

PMA Director Justin Johansen sought Bulk Recovery Solutions’ guidance on the possibility of comingling the waste material with other admixtures to be reused in the form of concrete blocks.

Bulk Recovery Solutions, a licensed EPA waste facility and one of NSW’s leading waste operations for the treatment of solid and liquid waste, analysed the waste material and determined that it could be recycled into concrete blocks.

OUTCOME:

By acting quickly and cohesively using industry-leading knowledge and cutting-edge equipment, PMA solved the time critical problem for DM Roads with an emphasis on safety and efficiency. All contaminated material was promptly removed from the drainage system and waterway in a tireless, round-the-clock effort.

But PMA’s commitment to the customer and to finding new ways to add value drove the team to go further for DM Roads. Unprompted and with the help of Bulk Recovery Solutions, PMA was able to return 30 new concrete blocks back to DM Roads to be used for future RMS projects. As a company, PMA prides itself on keeping its clients one step ahead – whatever the job. PMA delivered on this commitment for DM Roads.

BRISBANE CITY COUNCIL: GAILEY ROAD FLOOD GATES

CLIENT: Brisbane City Council
INDUSTRY: Local government, QLD
TYPE OF PROJECT: Flood gate restoration
WHEN: (when work commenced and when project was finished, or duration of project)
VALUE: $145,000

Brief:

Residents on Gailey Road, Toowong in Brisbane’s inner west reported unpleasant odours coming from a flood gate outlet into the Brisbane River. Brisbane City Council engaged PMA to develop an innovative solution to clean the flood gate, sump and outlet pipes to restore flow and remove the offending odours.

CHALLENGES:

The flood gate outlet directly interfaces with the tidal Brisbane River. Environmental values for water quality released into the Brisbane River were of paramount priority, particularly for turbidity and suspended solids.

PMA needed to find a solution that would enable the work to be done and the problem solved as quickly as possible without letting contaminants enter the Brisbane River water system. This required PMA to design and construct a sediment retention / water settlement basin in the work area to reduce the flow of the water and allow for settlement of sediment.

PMA SOLUTION:

To quickly solve this delicate problem, PMA called upon its portable GeoDesign Barrier Dam system to temporarily dam the site and create a work area free from inundation. To maintain the dry working area, pumps were set up to bypass the incoming flow of water around the GeoDesign Barrier Dam downstream and into the Brisbane River.

Using the Barrier Dam system, functional work hours were increased from a three-hour low tide window to a full day, during which debris removal could be performed. The barrier dam prevented incoming tidal water levels of up to 2.2 meters and the project was completed without any instances of environmental non-conformance.

OUTCOME:

PMA removed over 200,000L of sediment-laden material from the flood gate and outlet pipes over the eight-day project period. Over that period we moved three or more truckloads of sediment material offsite every day.

Once the work was completed, all flood gates were tested from 0% – 100% operating range and were determined to once again be functioning as intended. PMA recorded and delivered a detailed condition report to Brisbane City Council for the pipe network and floodgate infrastructure.
PMA safely and efficiently delivered this project:

  • within a highly urbanised and sensitive environment;
  • within the forecast time and cost schedules; and
  • without incident or community complaint.

“PMA REMOVED OVER 200,000 LITRES OF SEDIMENT-LADEN MATERIAL OVER THE EIGHT-DAY PROJECT PERIOD.”

TWEED SHIRE COUNCIL: THE LIGHT AT THE END OF THE CULVERT

CLIENT: Tweed Shire Council
INDUSTRY: Local government, NSW
TYPE OF PROJECT: Culvert cleaning
WHEN: (when work commenced and when project was finished, or duration of project)
VALUE: $10,500

BRIEF:

Tweed Shire Council contracted PMA to deliver safe and efficient Culvert Cleaning under Tweed Coast Road in the Northern Rivers region of NSW. The 4x under-road culverts were 100% of heavy silt and debris, including roots.

CHALLENGES:

Conducting Culvert Cleaning under busy carriageways can be a hazardous task due to the nature of the work involved. Culvert cleaning involves cumbersome manual handling of difficult materials in a confined space, where there is a constant risk of exposure to fumes from the busy road above.

The Northern Rivers region is also a significantly environmentally sensitive area. The intermittent creek feeds directly into Cudgen Creek, a well-known and highly visible estuary. As such, maintaining visual acuity downstream of the work area was paramount.

PMA SOLUTION:

To solve the problem for Tweed Shire Council, PMA employed its Microtraxx Remote Culvert Cleaner, a highly efficient machine that specialises in unmanned entry into culverts to clear high volumes of debris. PMA deployed the Microtraxx because it is specifically designed to work in environmentally sensitive areas. It runs on a biodegradable synthetic oil, which enabled PMA to pre-emptively minimise the effect of any possible spills or leaks during operation.
By operating the Microtraxx from a safe and well-ventilated area, PMA was able to efficiently and thoroughly clean the four 4m x 2m culverts and return them to fully operational status in 4.5 days. PMA achieved this with no manned entry into the potentially dangerous work area, which solved the problem while greatly reducing risk.

OUTCOME:

By tailoring a solution that specifically addressed the immediate needs of Tweed Shire Council, PMA was able to clear 360m3 of silt and debris from the four culverts under Tweed Coast Road and return them to full functionality in 4.5 working days. This was made possible due to PMA having highly skilled operators and the best equipment to rapidly solve the problem for Tweed Shire Council. PMA’s Microtraxx Remote Culvert Cleaner removed 100% of the sediment build-up that was blocking the culverts, allowing full flow for the upcoming wet season.

“PMA WAS ABLE TO CLEAN THE FOUR 4M X 2M CULVERTS AND RETURN THEM TO FULLY OPERATIONAL STATUS IN 4.5 DAYS.”

PMA CONDUCTS OPEN DAY TO MEET BCC STAFF

At PMA, we believe that innovation and communication are key to providing clients with a mutually beneficial outcome over the life of a contract. As part of the Brisbane City Council Ancillary Stormwater Asset Cleaning and CCTV Inspection contract that PMA has been servicing over the last five years, we have taken specific steps to meet in person with BCC staff to explain the work that we are doing for council. This saw PMA conduct an open day where council officers could get up close and personal with the PMA fleet of trucks and equipment and learn more about our capabilities.

To build on the PMA-BCC relationship, our open day allowed BCC managers and technical officers to view first-hand the capabilities, attachments and equipment available for hire during the term of the BCC Stormwater Asset Cleaning and CCTV Inspection contract. On the day, PMA provided subject matter experts who imparted detailed knowledge about the operation and use of the available suite of root cutting nozzles, penetrators, impact nozzles and warthogs that PMA employs to clean BCC’s drains.

The open day also gave PMA the opportunity to present the latest additions to the fleet servicing the BCC contract, including our purpose-built Spoutvac combo unit, and GPT 1, a support unit designed specifically for improving ease of access into Gross Pollutant Traps. Both units were selected to fill a niche in the BCC contract and ensured that PMA was providing cutting edge
solutions and best practice service to BCC through value-adding initiatives over the course of the contract.

OUTCOMES:

The open day was a resounding success for both PMA and BCC. PMA was able to communicate to eight BCC employees fundamental knowledge regarding the capabilities of vacuum trucks, their attachments and support vehicles. This helped BCC to improve decision making processes in the work request phase moving forward.
