Widefield Wastewater Treatment Plant
Fountain, CO

General Description

Widefield Water and Sanitation District (WWSD) owns and operates a wastewater treatment plant located on the northern portion of the City of Fountain. The plant provides secondary treatment, a process that uses large round tanks to separate solids from water by gravity. The existing plant is currently rated for 2.5 million gallons per day (MGD) to serve a population of approximately 18,000 people within its district boundaries.

Since the original construction in the early 1940’s, the facility has undergone multiple improvements. The most recent improvement project included: installation of sludge dewatering equipment inside an existing building with installation of associated rotary lobe feed pumps, polymer feed equipment, dewatering filtrate pump, and a shaftless screw conveyance system. To protect the trucks from weather while solids are being loaded, construction of an exterior sludge distribution shed was also accomplished. KWS Environmental supplied a horizontal conveyor to accept solids from the two screw presses, an inclined conveyor, and a truck loadout conveyor with six drop points.

KWS Advantages

Truck Loadout System for Widefield WWTP in Fountain, CO - KWS Manufacturing

Conveyors and Supports are Constructed from 304 Stainless Steel

The KWS team started working with the consulting engineer on the project improvement design over two years before equipment startup. KWS provided conveyor sizing, layout options and technical information so specifications and budgets could be developed. KWS was selected by the contractor due to the upfront design effort and KWS’s competitive pricing. With 3D modeling capabilities, KWS easily coordinated interfaces such as adjoining equipment and building layout. The initial KWS design submittal was immediately approved with very minimal changes, saving the engineer and contractor time that would otherwise be spent on tedious revisions and re-reviews. The KWS equipment shipped early to meet the contractor’s installation schedule. Once installed, KWS sent a licensed professional engineer to the site for conveyor startup and training. The KWS engineer worked with the site system integrator to make sure the startup went very smoothly.

Special Features

KWS provided a shaftless screw conveyor system with abrasion resistant spirals and UHMW liners to handle the moist, lumpy dewatered biosolids. All exterior components of the conveyors and supports were manufactured from 304 stainless steel to prevent corrosion.

Biosolids discharge from two screw presses into a receiving conveyor, which directly feeds into the incline conveyor, reducing the overall footprint of the conveyor system. The inclined conveyor was designed with a tubular housing to increase conveying efficiency. The inclined conveyor then discharges to the truck load out conveyor. Trucks are loaded with biosolids using multiple slide gates. The gates are opened as required to evenly fill trucks for maximum usage. The KWS design is very compact and efficient.
