The Rain Water Management System (R.W.M.S) is a system

that is used to collect rainwater during rainy days and

allocate it around a household automatically according to a

users needs. The user can choose how much water to

allocate to different parts of the house using a graphical

LCD and touchscreen. The system runs on an internal

scheduler which will automatically detect the right time to

do certain tasks. The system will also perform automatic

leak checking and maintenance and alert the user if there is

a problem.

The entire system is centralised around the GUI system

which works only with a touchscreen and Graphic LCD. It

has 3 screens and to navigate to each screen you perform a

slide gesture on the screen, which navigates to the next

screen, like an Android phone. The three screens are: Water Allocation screen, which allows you to

allocate water around the house as desired, the Scheduler screen, which shows the current system

time and at what times the scheduled tasks will begin and the System Overview screen, which shows

the allocation summary, the status of the main tank, whether the filters are clean or dirty and if

there are any leaks in the system. When the time for water allocation is ready, the system transfers

the water around the house working on a principle of sequence control. The water allocation can be

done in either percentage or millilitres/litres, whichever is

preferred by the user. This affords for flexibility. In cases where

the actual water is less than the requested amount, the system

adjusts dynamically and does intelligent adaptive control to

allocate the water around the house.

The system also has a maintenance mode, where it carries out

leak checking around the systems pipes. This happens at

another time, preferably night, and the system fills with water

to check if there are leaks. If there are, the system empties out

all the water and locks up. This is a safety measure. It also

detects when it is raining and automatically opens and closes

the top lid to collect the rain.

The system works with actual water and has been tried and

tested. Though the process is of moderate speed, the accuracy is impeccable and it is a system that is

very much needed in this eco-friendly environment around the world where people are trying to save

money wherever possible.
