Each spring for about one month, North Texas Municipal Water District (NTMWD) suspends the typical use of ammonia to allow the remaining chlorine to keep the water disinfected as it travels through the system. This temporary change in disinfectant helps maintain the system and high water quality year round. It’s important to do this before summer because hotter temperatures can increase the potential for bacterial growth in pipes. This change in treatment is scheduled for March 2020. Please see the NTMWD website for more information:

At the water supply, the health and well-being of our members, employees and community are important to us. We understand the concern and uncertainty you may be experiencing surrounding the coronavirus (COVID-19) and are committed to being responsive to the needs of our members as the situation evolves. In an effort to support distancing and limiting the spread of the virus, Markout’s Directors and Staff are putting the following procedures in place: 1. No cash payments will be accepted effective 3/25/2020 (this will be a permanent policy going forward). We have several other payment options including bank checks, money orders, personal checks, ACH withdrawals, credit card by phone (1-888-993-9176) and online credit card payments (see our website: 2. No payments will be received at the front counter until further notice – personal check and money order payments may be placed in the mail slot in the office door that faces Walnut Lane. 3. The office phones will be staffed during regular business hours, but the office doors will be locked. If someone needs to transfer service due to a home sale or purchase, kindly call the office for instructions. 4. During this time of national emergency when so many people and children will be at home and possibly ill, we will not disconnect service for non-payment. Late fees will be applied and late notices will be sent as usual to comply with Public Utility Commission rules. 5. Since the counsel is that no more than ten people should be gathered together, we are postponing our Annual Membership Meeting which was scheduled for April 2nd. Once a new date is determined, we will notify our members. We strongly encourage you to use our online tools which can be found at The Board of Directors will re-evaluate these procedures as the situation evolves. Thank you for your cooperation and understanding. We pray that you and your families are safe and well.
