Domestic Service

WCI Engineering Services Team services and repairs hundreds of residential package sewage treatment plants, pumping stations and rainwater harvesting systems across the South West and beyond.

Our Domestic Service Contracts ensure worry-free functionality, retention of the manufacturer’s warranty and a full service history (a must have when you come to sell). All contracts are backed up by a Service Level Agreement ensuring responsive emergency call outs. WCI carries comprehensive insurance covering all our products and services and our work is guaranteed.

WCI responded very promptly and efficiently when I needed a broken aeration tube fixed urgently on my Diamond plant. They set out a quote for the work which was adhered to and advised on the state of the plant when they also serviced it. The WCI team were professional, friendly and very helpful in organising a visit date given they had a long journey to fit in with other customers in the area – saving us all travel time cost. I couldn’t recomend them highly enough for domestic sewage plant repairs and maintenance.

WCI supplied us with a Solido Sewage Treatment Plant for our Barn Conversion Near Fitzhead, Somerset. The plant was competitively priced and absolutely superb service from everyone that I dealt with at WCI. We didn’t realise that delivered promptly. We completed the installation ourselves before having the system commissioned by one of WCI’s skilled technicians, who was both knowledgeable and friendly. 6 months on and the system is running well – Thanks WCI!


Brad, Naomi, John, Duncan and Barry from WCI have been great team to work with, providing a friendly, professional high quality service at a reasonable price.

We worked with WCI for a number of years on our project and continue to use them to service the water treatment system. They consistently arrive as arranged and have provided invaluable advice and support to us in sometimes difficult times. Many thanks WCI!

WCI were the only local company to respond to a failed sewer pump at my home. As we potentially would have a back-up of sewerage, I was desperate to get the problem resolved quickly. At the arranged time Chris duly arrived, and after a lot of searching, managed to locate the failed pump, which was hidden under a gravelled driveway. The old failed pump was inspected, and a new one quickly ordered. Several days later the new pump was fitted and everything was back up and running. I was impressed with the speed and efficiency of both their engineer Chris, and the company as a whole, with excellent communication, and on-time visits. Would highly recommend.
