The City of Robinson holds a Texas Water Right to withdraw water from the Brazos River which is stored in an off-channel reservoir on Tinsley, just outside the City limits. From the reservoir, the water is pumped to the adjacent Water Treatment Plant where it receives conventional treatment before entering a reverse osmosis treatment train. The finished water is stored in a 565,000 gallon clearwell before being pumped to the distribution system. There are 4 personnel assigned to the plant.
Five deep water wells, producing from the Upper Trinity formation, augment the City's water supply year round. Each well is equipped with a ground storage tank ranging in size from 200,000 gallons up to 500,000 gallons and 2 or more booster pumps to deliver the water into the distribution system. The wells are maintained by distribution system personnel.
An 800,000 gallon concrete storage tank located at the highest elevation in the City provides pressure by gravity to all of the City, except the upper pressure plane, which is served by a 200,000 gallon elevated storage tank (water tower). Including the ground storage at the well sites, the system has the ability to maintain over 3 million gallons of water in storage. While summertime peak usage reaches 2.5 MGD, system capacity is estimated at 3.5 MGD. There are 3 personnel assigned to this area. Major construction work is contracted to the private sector under the supervision of the City Engineers.
