Abstract• Water conservation is the most important

strategy for water planning and management for the future decades.

Reducing the usage of water and recycling of waste water for various purposes such as cleaning, irrigation and manufacturing.

What is Water Conservation???

Background• Today our faucets are equipped with the

pressure–balancing control valve to help maintain water temperature in the shower

• Typically takes 15-30 seconds for water to become hot

Purpose• Water Conservation in Urban areas

• Improve water management practices• Design a system that diverts the below-

temperature, undesired water to an external reservoir using several 2-way

solenoids

Design

• 120 V DC Heating Element• (3) 2-way valves powered at 12V• 20 gallon water tank• LCD Display• PVC pipes and fittings• 120 V Relay • Wall outlet• 2x4 Studs• 10x10 plywood

Deliverables1. Collect data through measuring the actual amount of wasted water and the desired water temperature.

(September – mid October 2014) 2 weeks

2. Select and identify thermal sensor with measuring ranges in the vicinity of the desired temperature.

(Mid-October – End-November 2014) 6 weeks

3. Select equipment to be used in building a prototype, this may include:

a. Water heater (or a heating element) b. 2-way solenoid (connected to the major water tank and diverts water between the reservoir and the tub spout).

c. Water tanksd. Micro-controllere. Actuating device (i.e.: high torque servo motor)f. Pipes and hoses (PVC pipes, fittings, etc)

(October – End-November 2014) 8 weeks 4. Independent research on materials and project.

(November 2014 – January 2015) 5. Control the valve through the microcontroller using data collected from the sensor.

(End-November 2014 – End-February 2015) 12 weeks 6. Build the prototype perform final testing.

(March 2014 – End-May 2015) 8 weeks
