Coomba Park near Forster NSW. The clients, Elaine and Rupen Honnet required a very low maintenance system which also operated on on its own solar power.

Aerobic sand filter system under construction on the farm of Mr. Brian Wilkes of Stroud NSW. This system was an urgent replacement for a failed septic tank system.

A final layer of sand and gravel media is being applied to the aerobic sand filter. The blue liner material is designed to prevent contamination flowing either into or out of the filter.

AMP asked us to upgrade failed septic systems on five properties located beside the environmentally sensitive Tea Gardens River in NSW. AMP required that these systems produce very high quality waste water which was then to be dispersed to a sub surface disposal area. 

We replaced 3 failed septic systems servicing three separate cottages on this rural property. The big challenge on this project was dealing with the very heavy clay sub surfaces. The client also required a low visibility installation which could be easily obscured with minimal landscaping.

Markwell Plumbing have had the pleasure of helping Thiess Pty Ltd with wastewater management issues at various highway construction site offices over the years. This work in progress photo shows part of an installation at Karuah NSW where wastewater had to be safely disposed of into a native landscaped area.
