Diverse Exper se

PEC engineers have completed numerous City projects integra ng exis ng infrastructure and City staff interac on to op mize func on, opera ons and maintenance.

Bartle & West has completed much of the City’s road and u lity work including u lity coordina on and brings long-standing rela onships and knowledge of the local permi ng process to advance your meline and manage costs.

Black & Veatch has more experience with BNR facili es in Kansas than any other fi rm. Our nutrient removal experts will design solu ons, combining innova on with tried and true methods to best address your nutrient control challenges.

Pump Sta on 10, The Heart of the System

Pump Sta on 10 — Func onal, Reliable, Economical and a Good Neighbor!

High-Capacity Flow Measurement Support Building

Wet and Dry Wells

• Provide real- me, accurate fl ow measurement data into and out of the PS 10 site

• Employ mul -beam mul -probe open channel fl ow measurement along with closed conduit magne c meters—with opera ons and maintenance access

• Connect real- me metering data to control center via fi ber op c network

• Provide ability for KAW WWTP control center to communicate with PS 10 and Four Seasons to divert/retain dry and wet weather fl ows on command via gate systems and pumps

• Diversion/fl ow measurement structures would be accessible, all materials would be corrosion-proof, concrete treated for corrosion, and provided with odor control

• Mul ple dry weather pumps w/VFDs• Mul ple wet weather pumps w/VFDs• Infl uent fl ow control coordinated with overall control system• All discharges fi ed with magne c fl ow meter• Mul -compartment wet well for diff erent levels of fl ow

diversion and necessary maintenance• Wet well surface scum removal capability• Wet well grit removal capability - self cleaning• Op on for large debris removal basket• Onsite odor control - done before• Wet well and pump size and confi gura on cri cal with

respect to treatment plant capabili es• Protected (corrosion and storm) space for all electrical and

MCCs• Ready access to all pumps, meters, valves and support

equipment• Standby power connec ons• Poten al use of similar or same size equipment

• Provide secure containment for electrical and control equipment elements

• Provide double roof system to ensure weather proofi ng electrical/controls while maintaining building appearance

• Provide concrete containment structure for tornado protec on of cri cal equipment

• Provide hard-wired connec ons for emergency power from mobile sources

• Provide enclosed, accessible workspace for fl ow meters, valves, odor control equipment, etc.

• U lize long-las ng exterior materials• Ensure public acceptance with neighborhood mee ng• Ensure adjacent landowner acceptance with specifi c mee ng

The Nutrient Limit Ques on

> 10 mg/L TN; 1 mg/L TP versus 8 mg/L TN; 1.5 mg/L TP> TP limits easier to achieve than TN limits

Ditch vs. Basins

> Ditches: Longer Sludge Age; More Stable; Easier to Operate- More Forgiving; Can be Re-rated in Future> Basins: High Rate Ac vated Sludge; Harder to Control; More Easily Upset; Requires More Operator A en on
