Stormwater Management Program


Program History


The City of Manor received its first Phase II Municipal Separate Storm Sewer System (MS4) permit in 2015 from the Texas Commission on Environmental Quality (TCEQ). We are currently in our 3rd permit under the National Pollutant Discharge Elimination Systems (NPDES; in Texas it is TPDES).

About Our Program


The City of Manor has developed a program to meet state and federal requirements related to stormwater. The objective of the Storm Water Management Program (SWMP) is to reduce pollution that travels into our waterways.


What The City Does


Several departments within the City are instrumental in implementing this plan. The City of Manor staff: 



What Is Stormwater


Rainwater, snow, sleet, or hail that runs off streets, houses, lawns, and other sites. Since it is not able to be absorbed into the ground, it goes into storm drains and drainage ditches. Once the stormwater goes into the drains and ditches it travels through the stormwater pipes until it reaches a body of water such as a stream, lake, creek or river.


Why Protecting Stormwater Is Important


Stormwater is untreated and goes directly into our lakes, rivers, streams, creeks, or oceans. Wildlife use the bodies of water to live in and for food and water. Wildlife can become sick from pollution that travels with the stormwater.


Types Of Pollution Can Travel With The Stormwater 


  • Oil, grease, metals and coolants from vehicles
  • Fertilizers and pesticides from gardens and homes
  • Yard debris (grass clippings, leaves, etc.)
  • Pet wastes
  • Trash: such as drink cans, food wrappers, etc. 
  • Soil from construction sites and other bare ground 
  • Soaps from car or equipment washing


How This Pollution Affects The Environment


Oil, grease, coolants, soaps, and pesticides are toxic not only to wildlife but also to our drinking water supply. Pet waste has large amounts of bacteria that can make the water unsafe for recreational activities such as fishing or swimming. 


The City of Manor Strives to promote Community spirit through the preservation of our unique character and heritage, while fostering a dynamic economic environment.
