Loyal Customer:

Please be advised that Texas Operations & Professional Services (TOPS) has joined with Si Environmental, LLC (SiEnviro) and will be operating under that name starting January 1. We have made every effort to ensure that your service levels go unchanged and in many cases are improved. Your current account billing, payment information, as well as customer service contacts will remain the same.


As we complete the operational integration of our businesses, be assured that we are committed to delivering the high level of service to which you are accustomed. Any immediate changes that you may notice will be in relation to the company name change, the change of decals on the vehicles riding through your community and the change of logos on the uniform of personnel. You may also notice changes of the signage on District facilities and at our payment locations.


We will continue to keep you informed of important updates. In the meantime, please do not hesitate to contact us with any questions you may have. You will also still find many online services at, or by phone at 281-807-9500.
