Package pump stations are the most simple version of wastewater pump stations. They are versatile but are not as well suited to sites with a high water table or limited access for installation.
In terms of cost, they represent the most cost-efficient and easiest solution for smaller sites and can be up and running quickly. The tank is delivered to site with the pipework and valves already installed. Once surrounded in concrete, a single site attendance is required to install the pumps and commission the system, negating the need for a confined space entry.
However, if not installed correctly they are prone to failure from water ingress. They also have the shortest life span and are typically not structural units in them self. GRP package pump stations will typically not be adopted so although the upfront cost is cheaper, over their life span they typically end up costing more.
