BioFizz is a biological sanitation treatment product intended for use in both septic tank systems, as well as conventional urban lavatories
BioFizz is a biological product developed by CSIR Biosciences, intended for use in both septic tank systems, as well as conventional urban lavatories. Septic tank systems are widely used in various parts of South Africa, Sub-Saharan Africa as well as in various other developing countries. Most urban populations in these countries are provided with septic tanks; although in some other less developed countries, up to 45 % still use traditional pit latrines.
The septic tank system provides a cost-effective on-site sanitation mechanism, and is the most cost-effective, and likely the only practical approach for securing the health benefits associated with hygienic disposal of excreta. Although its use is advantageous, numerous limitations of the use of septic tank systems have been reported.
The BioFizz product can also be applied as a biological alternative in normal domestic water borne sewage systems, where environmentally aware customers can use the product to reduce the burden on sewage treatment facilities and ensure cleaner effluent traps and pipes. On-site, point-of-source treatments of these septic tanks and urban lavatory systems are required in order to suitably treat sewage generated from households. This form of sanitation is also being adopted by suburban lifestyle estates and game lodges across Africa.

An international research institute is helping the government of Sri Lanka to improve septage management in the country.
On 8 May 2013, the Colombo-based International Water Management Institute (IWMI) and the Ministry of Water Supply and Drainage signed a Memorandum of Understanding that provides a collaborative framework for sustainable septage management in Sri Lanka.
IWMI will contribute research data for the drafting of a septage management component of the national sanitation policy. The Ministry will lead implementation of the policy through an advisory committee headed by Minister Dinesh Gunawardena.
Only about 3% of Sri Lankans have a sewerage connection while the rest rely on latrines and septic tanks for sanitation. Safe disposal of septage (fecal sludge) is a problem because of a lack of treatment facilities in large parts of the country.
IWMI is studying a new approach in cities around the world, which treats the sludge so that it can be safely reused as agricultural fertiliser. With the rising costs of imported fertiliser, such an approach would not only benefit farmers but also allow better sanitation and environmental protection for all.

The implementation of a dengue control programme in Puerto Rico led to the discovery of previously unknown mosquito breeding sites underground. Research published in the March 2008 issue of Medical and Veterinary Entomology showed that large number of mosquitoes (Aedes aegypti), which transmit dengue fever to humans, were found to breed in septic tanks.
