Benefits of Advanced Responsible Wastewater Management

The Hydroscape approach to wastewater management is to evaluate the most appropriate and responsible long term solution for your site. This may include a range of recommendations from which you can make an informed judgement. In many situations the site and soil limitations may require the adoption of an aerobic wastewater treatment system (AWTS). Some units are better suited to intermittent flows than others and some have markedly higher energy and maintenance requirements or installation limitations. Linking AWTS with other recognised wastewater management techniques provides for multi-barrier outcomes where the combination of more than one technology delivers design synergies that are not available with a single platform management model. This highly advanced design technique reduces public and environmental health risk and may facilitate development that would not otherwise be possible with a single system. Moreover the overall capital, lifecycle and energy costs may be considerably less against something that appears a cheap solution upfront eg requirement for additional solar panels or site terracing may be reduced.

Designing long term, environmentally and socially responsible solutions underpins the Hydroscape approach to wasterwater managment.  Some of the benefits that can be achieved include:

  • Possibility of nil or reduced contract servicing of wastewater system;

  • No disinfection or root intrusion chemicals required with innovative sub surface distribution techniques;

  • Large diameter discharge apertures unlikely to ever block and by design, do not require root intrusion management. Pressure compensating sub-surface drip systems use micro irrigation emitters that require permanent root intrusion chemicals either in-line or by impregnated pipes. SA Water requires all sites connected with mains water to have serviceable non-return valves (RPZ) installed at water meter (currently around $1000) for any sub surface dripper system connected to AWTS.

  • Energy consumption can in some cases be reduced to nil or only around 0.05kW/day for only the days it is used. When it is necessary to integrate AWTS management into the design, consideration should be given to the overall energy burden and matched to the availability of energy sources. Hydroscape can assist with appropriate AWTS selection and installation;

  • Innovative soil based dispersal systems can hold up to 400L of storage capacity per metre providing considerable redundant storage that helps to avoid problems with overload events eg party or extended family stay. Surface dripper systems have no reserve capacity and can result in under treated waste and malodorous wastewater being discharged around garden;

  • Lawn can be planted directly over the any of the above systems. This is not possible for surface irrigation systems with chlorine disinfection;

  • Footprint of disposal system can often be smaller than that required for irrigation system and therefore frees up land for other uses;

  • The entire dispersal system can often be completely sub-surface offering high level of public health safety and reduced likelihood of odours. Surface irrigation pipes are vulnerable to human contact by children, UV degradation and damage from mowing, rodents and pets;

  • Innovative zoning techniques can deliver water to multiple areas of the garden without need for manual intervention.
