Wastewater Retrofits: Designing New Equipment Around Existing Infrastructure

A lift station can be a structure in the future that is filled with pumps, pipes valves, controls and electrical equipment, however its performance is largely assessed earlier. The final design of a lift station is influenced by many factors, including flow calculations, elevations on the site, pressures in the system as well as wastewater characteristics, peak conditions, maintenance access, control systems, and future capacities.

For project owners comparing the best lift station designers, the more useful question isn’t simply who can specify pumps. Who can translate the conditions of the site into a complete, practical system that is simple to set up, maintain and use?

Gravity Limits Itself

Gravity is often the most effective method of transporting wastewater, but the development pattern and terrain do not always work together. The newest commercial, residential and industrial developments are typically too high or distant from the existing gravity sewer infrastructure.

A lift station will provide the required force mechanically to move wastewater from one part of the system of collection to the next. However, designing one requires a thorough understanding of both normal operation and other situations that are less convenient, for instance, peak inflows, pump maintenance or equipment malfunction, or any future growth in demand.

Companies that are regarded as among the top wastewater engineers must therefore analyze the entire conveyance problem rather than considering the station as an isolated piece of equipment.

Existing Infrastructure Makes the Puzzle Harder

The only problem is not the new construction. A lot of municipalities are required to upgrade or replace older stations in order to keep essential sanitation infrastructures functional.

Forcemains, wetwells and other existing components, electrical services and controls boundaries, site boundary, and downstream infrastructure can limit the new design. Engineers need to decide what will remain, and what must be replaced and how the new elements are to be incorporated into the current system.

Romtec Utilities works across municipal, private, commercial, industrial, retrofit, and replacement projects, allowing pumping systems to be built according to the particular operating and ownership requirements of every project.

Stormwater follows different rules

The most skilled designers of stromwater systems using the search terms available must resolve a completely different hydraulic issue. Stormwater systems can undergo dramatic variations in their volume, based on the amount of rainfall, drainage capacity and allowed discharge rates.

Stations that serve detention basins, for instance, may need to temporarily store runoff until pumping it out at a set rate. Engineers must take into consideration flow, head conditions, water quality requirements, flood-management targets and the nature of the drainage system for which they are receiving.

Prefabrication is a way to move work from the site of work

Field assembly is a complicated process that could result in confusion in scheduling, errors delays, and changes to orders. Romtec Utilities uses substantial prefabrication before equipment reaches the site of the project.

Completing more assembly and quality-control tasks in a controlled setting can reduce the amount of construction that is required on the field. Romtec Utilities’s project-based approach will reduce the amount of amount of time needed to construct specific installations.

The process of commissioning is an integral part of engineering Success

It’s not enough just to put in all the parts for a station to be considered a proven one. Romtec Utilities offers installation advisors to assist in construction that includes starting up and control panel inspections pumps, operation testing, and training for personnel. Documentation is also available to provide operators with information on how to maintain the system and also to consider expansion plans in the future.

This stage is vital to owners who are looking for the most reputable lift station designers. A good engineering project should result in more than just an acceptable set of drawings. It should leave the proprietor with a working system that is well-trained, with a competent staff, valuable documentation, and equipment that is designed in accordance with the requirements the station will encounter in everyday operation.
