Aerobic Services of South Texas maintains Aerobic Systems. We provide maintenance contracts for both residential and commercial units. We write contracts that provide inspection and testing of the systems once every four months (State Required), to intervals of every month with us providing additional services, such as adding chlorine for disinfection. Please contact our office for a quote customized for your particular needs. Maintenance consists of cleaning and inspecting items like air filters and water pump intakes. We also check sludge levels and recommend pumping when necessary. We check air pressure and adjust to correct levels. All controls are tested for proper operation and we may adjust the sprinklers on spray applications. On systems that have drip field distribution, we clean the water filter and field flush the drip lines.
