Hydro Power in Sewage Works

Hydro Power in Sewage Works

Hydro Power in Sewage Works

(OP)

We are looking into the feasibility of installing a small hydro electric unit downstream of a sewage inlet works.

The system will be around 250kW. It shall be a Kaplan type reaction turbine.

Although the sewage inlet works has screens(6mm 2 dimensions)and grit removal, I still have concerns regarding ragging up and grit errosion and build up in the turbine.

Does any one know of a similar installation, or have they considered one?

Thanks

Sow

The City of San Diego had a small hydro unit on the outfall of their Pt. Loma WWTP at one time.  I'm not sure if it still operational.
