MEDLI - Model for effluent disposal using land irrigation

A user-friendly program for designing effluent re-use schemes

MEDLI software
MEDLI - the NO. 1 solution for the NO. 2 problem!


Effluent - what's in it, where should we put it, and what happens to the environment when it gets there?

These are the important questions being asked of our effluent-producing industries by a society increasingly demanding environmental sustainability

Irrigating effluent is nothing new. However, determining the quality and quantity of effluent available, specifying irrigation frequency and the amount required, tracking the fate of the water, nutrient and salt components, and assessing the associated health risk from pathogens, are not trivial tasks!

Climate influences on wet weather storage requirements and plant growth make the task even more complex and daunting. A robust storage-irrigation scheme for one area may be very unsatisfactory elsewhere, and a successful short-term effluent re-use scheme does not necessarily equate to a viable reuse scheme in the long-term.

To confidently address all of the facets of the effluent problem, you need the best help available.

And that's why you need MEDLI.

MEDLI does what the spreadsheets can't

MEDLI is a user-friendly Windows program for designing effluent re-use schemes. It models the complex dynamics of the effluent cycle on a daily time-step, using historical daily climatic data - up to 110 years if weather data are available.

MEDLI outputs

MEDLI allows you to design and test the long-term viability of an effluent treatment and irrigation scheme. You can identify weaknesses in the scheme, and explore alternative solutions until a suitable robust design is found.

MEDLI is well-suited to sewage effluent reuse schemes (both municipal and on-site), intensive livestock industries (piggeries, dairies, and feedlots), agri industries such as abattoirs, tanning, rendering plants and the like.

With MEDLI, the effluent issue becomes a transparent, logical problem-solving exercise backed by comprehensive text and graphical output.

Try capturing that sort of capability in a spreadsheet!
