Abstract:
A convenient supply of safe water and the sanitary disposal
of human wastes are essential ingredients of a healthy,
productive life* With this in view a critical appraisal
of the water supply and sewage disposal arrangements in the
University of Moratuwa was undertaken to explore suitable
means of improving the system- Thereby a more satisfactozy
and efficient service for the present and the future will
be ensured*
In this study consideration has been given to the suitability
of the present sources in terns of location, quality, adequacy,
storage facilities, etc* with regard to existing water supply
system*
In assessing the sewage disposal arrangements presently
prevailing attention has beoi focused on such aspects as
location of 3ewers, manholes and treatment units, etc*
Further a detailed investigation into the working of the
existing treatment units was also undertaken in order to
assess the performance of these units in terms of
20 and SS. removal of BOD5
Investigations revealed the inadequacy and inefficiency of
the present water supply system* There is evidence of faecal
contamination of groundwater*
Improper operation and maintenance of the sewage disposal
system have resulted in its overall inefficiency*
Provision of a central water tower of capacity of 120,000
gallons and centralised pump house is recommended* Further,
provision of a simple water treatment unit is suggested*
The need for immediate repairs to unit No: 2 and the disinfection
of all sewage effluent are highly favoured*

The introduction of a new central sewage treatment unit
incorporating as far as possible the present sewers and
manholes is recommended.
To obtain a satisfactory and efficient service a proper
management of the water supply and sewage disposal
arrangements is essential.
