SESL Enables Smarter, Sustainable Redevelopment

SESL Australia

From SESL’s perspective, nearly all redevelopments haven’t been brought into the 21st Century in their soil and waste management.  

Millions of dollars are wasted in nearly every development project in soil disposal to landfills, and quarried material being brought in for final landscaping and turf areas.That is why SESL believe that the ‘S’ in SUSTAINABLE stands for ‘SOIL’!

SESL has been busy working on a number of projects that help our clients comply with regulation and minimise risk to the surrounding community and environment, helping them achieve their business objectives compliantly and in an environmentally sustainable way.

SESL Australia has been particularly busy with site remediation – which involves coming up with smart strategies to manage contaminated land, waste, groundwater and surface water that will both have a successful outcome, and give real value for the client.  Our core has always been our soil and horticultural science, and something unique is produced when our experts come together.

Site Remediation and sports field Design for Western Sydney Council sports field:

Australia’s national identity is shaped around sport, so it comes as little surprise that many of SESL’s innovative solutions include improving sport fields, golf courses and community parks and landscaping.

This is where SESL Australia comes in. We were recently asked to design an upgrade of an existing sports field to a state level competition sports field in Western Sydney for a local government and Australian Football League (AFL). With our multidisciplinary soil science and contaminated land consulting skillset combined, we were able to provide assessment, reporting and design services for remediation of the underlying landfill, and design of the overlying sports field, to provide an environmentally improved AFL State-level sportsground. SESL provided an estimated $900 000 worth of savings in  Beneficial Reuse Survey, to reuse and amend existing soil in different horizons for drainage and growth media for the sports field turf.

This Beneficial Reuse Survey helped identify what soils could be evacuated, set aside, modified and reused for different horizons of soil – while maintaining the highest quality specifications for A Grade competition turf.

In addition, SESL Australia also handled a site remediation project for an industrial client at a nearby location. SESL saved the client $30,000 by reusing bioremediated sand from this separate project in our sports field project as part of the designed sports field soil amendment, after successful application under a NSW EPA specific recovery exemption and order (SRRE/O) to reuse it as part of the soil amendment at the sports field redevelopment site. This meant we cut down on sand use by 300 tonnes, which is nothing to sneeze at!

Our team combined various skills and disciplines (contaminated site specialists, horticultural specialists, soil scientists, NATA accredited laboratory, waste specialists) to significantly boost the value of the project. We managed to reduce waste to landfill by an estimated 6,500 tonnes and cut back on quarrying by 6,800 tonnes.

SESL has successfully provided beneficial reuse of soil and waste materials for water bodies, sports companies, developers and local and state government bodies, all over Australia, some times saving the client 10’s of millions of dollars and just as importantly, providing a sustainable solution in minimising waste and imported materials.

Going forward, SESL Australia is reaching out to help more councils, government bodies, sporting association, developers, businesses and organisations to save time and money by using better science for sustainable reuse of soils and materials, and helping with innovative approaches in their development projects, and bringing ‘SOIL’ back into ‘SUSTAINABLE’ projects.
