Wastewater

Qk4 staff members have planned and designed numerous wastewater collection and treatment systems for municipalities, public service districts, private residential/mixed-use developments, and industries throughout the United States.  This background includes new facilities of varying magnitude, as well as system expansion and cost-effective rehabilitation of existing systems.
Qk4’s capabilities include the management, planning, permitting, design, construction supervision and operational technical assistance of all components of wastewater systems, from treatment plants and pumping station to trunk sewer, siphons, tunnels and outfalls.  Easement acquisition services are also available.  Qk4 can provide either traditional design/bid services or implement a wastewater project on a design/build turnkey basis.

Drainage/Stormwater Design

Qk4 strives for “sustainability” and ecologically sensitive approaches to stormwater management.  Qk4’s experience and expertise in drainage/stormwater design ensures workable solutions to drainage problems in all types of environments.  Our staff has extensive experience in the preparation of Stormwater Management Plans, hydrologic and hydraulic, modeling, design of bio-swales and rain gardens, storm sewer and detention/retention basin design.  Our designs have alleviated drainage problems for high-profile developments, residential areas, shopping centers, highways, and industrial parks.  We offer a full range of services, including permit application, zoning ordinance amendments, hydraulic analysis, design, and construction specifications.  We are also experienced in handling stormwater pollution issues that relate to the  U.S. Environmental Protection Agency’s (EPA) Municipal Separate Stormwater Sewer System (MS4) program.
