1. Introduction

The Town of Killingly, Connecticut (“Town”) invites sealed proposals from qualified pump manufacturers, suppliers, and contractors for the furnishing and delivery of one (1) new sludge gravity thickener pump for use at the Town’s Water Pollution Control Facility.

The basis of design for the sludge gravity thickener pump is a SEEPEX Model BN35-6LS progressive cavity pump, configured for municipal wastewater sludge service. The specified model establishes the minimum acceptable standards for performance, materials of construction, configuration, reliability, maintainability, and service life.

Proposers may submit an approved equal positive displacement pump, including progressive cavity pumps or other proven positive displacement pump technologies, provided the proposed equipment meets or exceeds the basis-of-design pump in all respects. Any proposed equal shall be specifically designed for continuous-duty municipal wastewater sludge applications and shall demonstrate equivalent or superior hydraulic performance, solid handling capability, materials, maintenance accessibility, operating life, and documented service history in similar installations.

The Town reserves the right to determine acceptability of proposed equal equipment based on compliance with this and the overall suitability of the equipment for gravity thickener sludge service.

This contract is for equipment supply and delivery only, unless otherwise noted. All furnished equipment shall be new, unused, and designed for continuous-duty municipal wastewater sludge service. The pump shall be manufactured, tested, and delivered in accordance with applicable industry standards, manufacturer recommendations, and generally accepted best practices for wastewater and sludge-handling equipment.
