Water Conservation & Quality

Daily water quality sample procedure

Water quality samples begin with the water quality vehicle which contains all equipment/instruments needed to collect the water samples.  The equipment/instruments include sampling tower, isotope alcohol, propane torch, sample bottles, cooling source (portable refrigerator or ice filled cooler). 

Upon arrival, the connection and sample tower are sterilized using alcohol and a propane torch.  The sample tower is connected to the sample connection site and the sample bottle is filled with water by opening a valve on the sample tower.  The sample bottle is addressed and stored in a portable refrigerator or ice filled cooler for transport to the NTMWD laboratory.  The NTMWD lab checks for any contaminants and reports back to the City of Rockwall on the quality of our water.

The current drought should remind us that water is no sure thing.

Low Flow Toilets
The toilet is the single biggest water user in your home. Flushing accounts for about 38%, more than a third, of the water used within your home each day. Replacing an old model toilet with a new low-consumption toilet could automatically and permanently cut your home water consumption by 25% or more.

Water Efficient Appliances
Thinking about replacing that old, worn-out clothes washing machine? High efficiency clothes washers save water, energy and space in your home. Most are front-end loaders that use tumbling action to get clothes clean. Look for the Energy Star Label to ensure that you're buying the most efficient product possible.

Consider this: High efficiency clothes washers use 30% - 50% less water, that's 5,000 gallons per year! They use 50% - 60% less energy to run. They require 1/3 less detergent. Your clothes will get less wear and tear in a high efficiency washer. They'll need less time in the dryer, too.

High-Efficiency Dishwashers
High efficiency dishwashers use about 6-10 gallons of water per load of dishes (some use as little as 3.7 gallons!). Compare that to 9-12 gallons per load for average dishwashers and 20 gallons for hand washing. Many newer models require little or no pre-rinsing of dishes – that's more water and time saved.

It is the goal of many individuals and groups alike to promote water conservation practices by raising awareness of the value of responsible water management.  We further would like to raise awareness to the need of adopting water-wise landscaping, gardening and watering practices.  It is important to all of us!
