Sheaffer & Roland Inc. has over 3 decades built a reputation in the design and operation of Wastewater Reclamation and Reuse systems. Key benefits of those systems, which range in processing capacity from 18,000 gallons per day (Glenwood School for Boys and Girls) to 24 million gallons per day (Beijing), are their environmental friendliness and the flexibility they offer to developers.
How it works
In the typical Sheaffer & Roland wastewater system design, wastewater is directed to influent pump stations. Then the wastewater moves through a comminutor, which shreds the waste, after which the material moves to deep aerated treatment cells, goes through a sand filter pump station and, finally, there is filtration and disinfection. An irrigation pump station helps complete the reclamation and reuse process.
The reclaimed water is ready for reuse after 40 days of treatment, but because of inclement weather there are many days during the year during which irrigating cannot be done. Therefore, storage lagoons are provided, which then are drawn down during times favorable for irrigation.
A golf course superintendent wrote to John R. Sheaffer II, president of Sheaffer & Roland, saying, in part:
“. . . we do, in fact, syringe the greens during the day with the reclaimed water from the Sheaffer & Roland Wastewater Reclamation and Reuse System. Because the irrigation water has essentially zero coliform it poses no health risk to my employees or the golfers. Irrigation with reclaimed water is recognized as preferable by the PGA and is widely used throughout the country. Syringing the greens with this same water by professional staff is likewise widely done and accepted.”
The Sheaffer & Roland operation is referred to as a zero-discharge system, because none of the treated wastewater is discharged into creeks or streams, as is usually the case with conventional treatment systems, but onto golf courses for irrigation. The Sheaffer & Roland wastewater reclamation and reuse system thus is regarded as more friendly to the environment than are the conventional systems, since nutrients from the discharges of those systems suggest negative implications for aquatic life.
