Our SERVICES
Precision subsurface drainage solutions that protect land, improve performance, and maximise productivity across sports fields, horticulture, agriculture, and developments—designed, installed, and maintained by experienced specialists.
Sports field drainage
If your sports field struggles with waterlogging, muddy patches, or constant downtime, Subsurface Water Management delivers fast and precise subsurface drainage that keeps turf dry, safe, and playable year-round. Using laser-guided one-pass installation and low-impact machinery, we install accurate, efficient drainage systems with minimal disruption to your surface. Our process includes a full site assessment, precise trenching and pipe installation, clean backfilling, and final checks to ensure everything flows perfectly. The result is a firmer, safer field that drains quickly, requires less maintenance, lasts longer, and keeps players, schools, clubs, and communities happy across all field types—from footy and cricket to soccer, hockey, and multi-use ovals.
Horticultural drainage
Smart subsurface drainage helps your plants thrive by removing excess water, improving soil health, and boosting productivity across vineyards, orchards, vegetable farms, and nurseries. At Subsurface Water Management, we design and install precision horticultural drainage systems using laser-guided one-pass technology that digs, pipes, and backfills in one efficient motion. Each system is tailored to your soil, slope, and crop type, ensuring healthier root zones, reduced disease, and long-lasting performance. With fast installation, minimal disruption, and expert planning from assessment to finishing touches, our solutions deliver stronger crops, better yields, and long-term value for growers of all scales.
Agricultural drainage
Maximise crop health and long-term productivity with precision subsurface drainage designed for broadacre farming. At Subsurface Water Management, we install laser-guided, one-pass drainage systems that improve soil structure, reduce waterlogging and salinity, and keep your paddocks accessible year-round. Our deep-trenching capability, perfect grade control, and detailed CAD planning ensure reliable drainage flow across all soil types and landscapes. With faster installation, minimal disruption, and proven benefits like healthier crops, better yields, and reduced downtime, our tailored systems offer a cost-effective solution for broadacre cropping, grazing, irrigated paddocks, and farms facing persistent water or salinity challenges.

Keep your drainage system performing at its best with professional maintenance from Subsurface Water Management. Our services—including high-pressure jetting, subsurface repairs, and contour drain maintenance—prevent blockages, reduce waterlogging, and extend the lifespan of your drains across sports fields, farms, and horticultural sites.

Regular maintenance improves drainage efficiency, protects soil and plant health, lowers repair costs, and ensures your land remains productive and accessible year-round.
OUR LATEST PROJECTS
Ray Owen Reserve – November 2025
We were involved in a larger scale project of rebuilding the oval at Ray Owen, we were working closely with Sports Turf Construction making time frames and communication important, this project involved a lot of hard rock digging with specialty rock teeth on our 2620 Masten Broek machine, we installed 6.5kms of Subsurface Drainage linked up to 225mm – 375mm collector pipes into concrete pits including concrete headwalls as designed. This was another Project we worked closely with intercompany businesses to achieve a great outcome for the City of Kalamunda
OUR LATEST PROJECTS
Highway Construction – Oakajee Project – May 2025
We were engaged by Highway Construction to trench and install 1.2kms of 100mm Subsurface Drainage and Rip Raps along the batters on the side of the new highway to alleviate the subsurface water pushing up from the sub-base under the road.
This was a challenging job as we had a specific time frame to complete, and the use of a specialized Rock cutting machine as the soil profile was predominantly a hard rock.
OUR LATEST PROJECTS
Local Wineries – Cullen Wines, Woodlands Wines, Edwards Wines – 2025
We are continuing to install Subsurface Drainage throughout the Southwest Wine Country helping to reduce Waterlogging and increase fruit growth, using our smaller 1012 Masten Broek machine we can fit between the existing fruit rows causing minimal disruption and damage to the area.
OUR LATEST PROJECTS
Woolkabin Farms Wagin – April 2025
With our one pass laser guided 2520 Plow machine we Installed 2kms of Slotted Socked Draincoil throughout waterlogged areas of the Grain Farm, this will increase crop yield within the first year of planting in these areas
OUR LATEST PROJECTS
City of Gosnell’s – Jean Garvey Oval – March 2025
Jean Garvey Oval was experiencing extensive flooding on the Oval during the Winter period, we installed over 3.5kms of 100mm & 160mm of Subsurface Drainage encased in Aggregate and finished with Topsoil as per specific design, this not only helped with the flooding but also increased the grass root structure strength and health. This was another Project we worked closely with intercompany businesses to achieve a great outcome for the City of Gosnells.
OUR LATEST PROJECTS
Kirk Whiting – Farm Munglinup
This land was experiencing Waterlogging and Salt Scouring, we installed 7 hectares of Subsurface Drainage encased with aggregate with our 2520 Masten Broek Plow, this improved crop yield by 2.5 tonnes per hectare of Canola in the first year, with a return on investment in 2 years.
