About Us

OSD's design service provides site and soil evaluations (which include a site investigation and assessment), permeability soil tests and preparation of hydraulic engineering drawings and documentation for your application to your local council.

In addition to the standard design service, we can advise you as to the best greywater system for your needs. These range from low cost diversion devices to high end home greywater treatment plants. Be sure to check out our links page for a few alternatives!

We are covered by BSA insurance (QBSA 1018637) and Professional Indemnity insurance to the value of $1,000,000.00

On-site Sewerage Designs was started as a home-based business in 2000 by John and Kaye Hammond in Highfields. Today their daughter and son-in-law , Deana and Ben Meyers, run the business from an old shop on the corner of Raff and Logie Streets in Toowoomba.

We are very proud of our 9 years of designing residential and commercial on-site sewerage facilities for our customers and look forward to adding you as one of our valued clients.

Please don't hesitate to call Robbie Morgenstern or John Hammond at the shop on (07) 4637 9633 or on the mobile 0409 264 278. You can also drop in any time during our business hours -8:30 to 4pm Monday - Friday or send an email to onsitesewerage@bigpond.com whenever it is convenient for you.

We are only too happy to discuss your on-site sewerage and greywater needs with you.
