**1.3 Justification**

Vermifiltration is a low-cost method that is eco-friendly, non-labour intensive, and it enables the treatment and reuse of wastewater [10]. LSU wastewater is disposed into the environment using septic tanks, thus increasing chances of pollution of the soil and underground water. Vermifiltration induces a decrease in COD, chlorides, TDS, TSS and pH in an efficient manner. The water is disinfected and clean enough to be used for farm irrigation and other non-potable uses. Some developed countries are using the system, and it has been highly recommended for developing countries since it is economically feasible and does not require a lot of maintenance and expertise. This study would therefore enable LSU to be able to reuse its wastewater for multiple tasks such as landscaping, construction, fire protection, irrigation of sport grounds and crops. This technique could be further utilised at household level, thus promoting decentralisation of wastewater treatment. The application of this low-cost sewage treatment system would go a long way in availing wastewater for irrigation and other non-potable water uses especially in the semi-arid areas.
