What is the basis for the sewer user charge?

The sewer user charge is based on your water usage for the six month period of November through April. The water company provides the Water Pollution Control Authority with actual water usage for all properties in Stamford. The charge is based on the "winter usage" to avoid charging for heavier summer uses such as watering your lawn and garden, washing your car, or filling your pool, which do not impact the treatment system. If a property has a well usage bills are based on the residential average for sewer use in lieu of water usage readings.
